Chemical Change Science Projects – Cool Chemistry That a Student Can Do

Chemistry science projects involving a chemical change are often chosen by middle and high school students. Many kids like to do an experiment with a dramatic chemical change. When searching for a project, it can be difficult to find an experiment with chemicals that are easy to find, and easy to work with.

One popular project involving chemicals is an experiment determining which fruit or fruit juice has the most vitamin C. A simple indicator is made with cornstarch and iodine. Students (and parents) enjoy watching the chemical reaction that occurs along with titration, which is a fancy way of saying “putting in drops”. This project can be modified in several different ways, allowing your student’s creativity to shine. We get letters from many students telling us that this easy science project was submitted to the fair, and was chosen as a winner.

Another great science project involving a chemical change is watching what happens as yeast ‘eats’ sugar.  In this project, warm water and yeast are placed in a bottle with a bit of sugar. A balloon is placed over the mouth of the bottle. As the yeast consumes the sugar, carbon dioxide is released, causing the balloon to blow up. This project is so much fun to watch that our kids did it over and over until we ran out of yeast.

Both of these projects can be done as demonstrations; they offer dramatic reactions that students will be able to observe immediately. Both science projects can also be experiments. They naturally lend themselves to a question, the formation of an hypothesis, and testing. The results can easily be graphed to form a conclusion.

5th Grade Science Fair Project Idea

It’s that time of the year again! Time to create, design and carry out a science project for the school science fair. Stumped? Don’t worry this article will help you plan a 5th grade project in science.

Here is a great 5th grade science fair project idea:

Every 5th grade project in science needs these important sections: title, materials, purpose (of the experiment), hypothesis (what you think is going to happen), procedure, results and conclusion. For this 5th grade science fair project idea:

Title: Come up with your own title!

Purpose: We all heard the saying water and oil do not mix. Why? Water and oil are both liquids and should mix like liquids. What will happen when we actually test this saying and mix oil and water? What will happen when we mix honey in? What will happen when when place objects in this mixture?

Hypothesis: This section is for your predictions. What do you think will happen when you pour the liquids in the jars? What do you think would happen to the objects? When you place objects into water, they usually sink. Do you think this will happen when you place objects in liquids that are not water? Don’t worry about being right! Hypothesis can be wrong, after all you need to do the experiment to find out.

Materials: For this science fair project idea, you will need

honey
small objects of different weights such as paper clips, coins, toys, marbles, etc.
two different jars that are at least 8 inches tall
water
vegetable oil
food coloring

Procedure:

Pour honey into one jar so it is 2 inches high.
Food color the water (pick whatever color you like best!) and then pour 2 inches of water into the same jar with the honey.
Then add oil to the same jar, 2 inches high again.
Pour the liquids in reverse order in the second jar. (oil, water, honey)
Put the objects in one jar. See what happens to the objects after 10 minutes, one hour, two hours.
Repeat step five for objects in the second jar.

Results: What happened? Describe everything. You don’t need to include explanations of why something occurred. Make sure to bring to jars to the science fair!

Psychic Development – Exercises to Develop Your Psychic Abilities

Without question there are many exercises that can be practiced in order to enhance our psychic development. We all have some psychic ability. To what degree depends on how open you are and your willingness to practice your psychic development. Many advanced psychics practice daily their psychic development skills in order to keep themselves in tune and on top of their game. We will talk about a few basic psychic development exercises that can be used by anyone with a yearning to move forward energetically and develop stronger psychic powers.

Exercises for development:

Attuning with the white light – Practice every morning imagining that you are encompassed with a beautiful white light. Imagine the white light falling all around you and forming a protective circle around your body. Become familiar with this white light until you make it your own. Over time you will learn to work with this white light for protection, healing and awareness.
Attuning the chakras – With this exercise imagine the colors of the chakras on your body. Starting with violet for the crown chakra, moving to indigo for the third eye, then blue for the throat, and green for the heart, yellow for the solar plexus, orange for sacral and red for the base chakra. Become attuned and familiar with these colors and from there you can learn to balance them.
Build a psychic shield – When one starts to use and work with their psychic energy, it becomes necessary to build a personal psychic shield. We don’t want out energy to be drained by others or any negative influences to penetrate our psychic energy. Imagine a shield surrounding your body of radiant white light. Ask this shield of white light to protect you from any negative or intruding energy. Ask that only positive, uplifting energy be allowed through.

The three psychic development exercises may seem ultra simple, however they are imperative when you start on your path to using your psychic energy. The first step is to be in tune with yourself and then you can start to tune in to others. Remember that psychic development is ongoing most likely throughout your entire life. Don’t be in a rush, allow yourself to grow into your spirit and you will be amazed at how powerful you are.

Telepathy For Beginners – How to Begin to Be Telepathic

Communication through means other than senses bears the name of telepathy. It consists in transmitting and receiving information to and from someone else’s mind. We all know from experience that these things do happen. Here is an example of telepathy.

I was planning to go on a trip to a foreign country a few months ago. I ordered my flight ticket and received the flight details with the name of the airport where the plane was due to take off. On the big day, before heading for the airport I checked my flight once more, just to be sure everything was all right, and I was surprised to see that my plane had been directed to another airport in the city.

That came as a shock because I had checked on the previous day and no changes had occurred yet. Fortunately this did not interfere with my plan and everything went smoothly – I got to the airport just in time to catch the plane – but this incident made me take a moment and think more thoroughly of the connections that human mind can establish with other minds. In this case the message may have been sent to me spontaneously by someone who found out of the change before I did or by the airport staff.

This was a typical example of spontaneous telepathy, the kind of connection that is established irrespective of the receiver’s or sender’s will. However, telepathy can be practised intentionally and the effects are the same. A message reaches the receiver because the sender wants him or her to get it and mentally concentrates on that purpose. This is called deliberate telepathy and there is a very good exercise that beginners may do in order to learn how it works.

Here is a typical telepathy exercise for beginners. Choose someone you feel comfortable with, a very good friend you have a lot in common with. It is easier to send and receive information to and from someone you know well. Your friend should sit in the opposite corner of the room. Grab a pack of cards and start looking at one of them, trying to make your friend ‘receive’ the image of that very card. Your friend will then write down the impression he or she has got from this attempt of yours. Do the same with another card and so on, till you have ‘sent’ the images of the whole deck of cards to the receiver. Check your friend’s notes to see if he or she has got the right messages. Then reverse roles and be the receiver yourself. In this way you may understand how good you both are as senders and receivers. After practicing this with all the cards twice or three times, you should have a break so as not to get bored. When you have seen some improvement in the quality of the messages sent, you may as well practise this exercise long distance if you and your friend agree to a certain time and each of you tries sending an image for five minutes. Next time you meet, you can compare the results.

Some people are better senders; others can receive messages more easily. There is also a certain number of people who can do both at a very high level. They say ‘practice makes perfect’ which is fairly true about telepathic exercises as well. The more you practice the more details you are likely to send or receive and in time you will be able to ‘manipulate’ more complex thoughts between you and your partner.

7th Grade Student Science Fair Project Idea

This is a science project to test if fluoride actually protects your teeth from harsh beverages we eat and drink daily. Instead of using our pearly whites will will test this theory on egg shells. This is an easy science project for your 7th grade student or middle school kid. An 8th grader or high school kid may also want to do this experiment as well. You can make it as in depth as you need to or as easy as possible.

You will need these supplies

10 glasses
10 eggs
Soda
Vinegar
Fluoride from a local dentist
Lemon juice
Coffee
milk
Paper towels
Graph paper

Experiment instructions:

Divide the glasses and eggs in half. Place one in front of each cup. Place 5 of them on side of a table or counter top and the other half on the other end to keep them separated. Pour soda in a glass at each end so that you will have two containers with soda in them, one in each group. Now place vinegar in two cups the same as the soda. Put coffee in the similar way and then lemon juice and finally put milk in the last two. You should have 5 glasses on each side that have different liquids contained inside of them and they are the same as the cups on the opposite end of the counter.

Now take the fluoride and wipe it on 5 eggs. Let them sit for about 1 hour.

Place the group with no fluoride into their glasses and after the 1 hour place that bunch into their cups. You may want to do this in the evening because you will want to let these sit overnight.

In the morning place a paper towel in front of each glass. Using a spoon remove each egg carefully and place on the napkin in front of the cup.

Using your graph paper make notes from your visual observations. Now carefully pick up the paper towels and pipe any excess residue from each egg separately. Notice the shell exterior of each and make notes.

Did any particular liquid change the structure of the shell? Did more than one beverage change the outside hardness and how?

Compare the fluoride eggs to those with no protection. Was there a difference in those coated versus those without?

This is where your research needs to come into play. If you notice effects of the shell, structure, or strength decide what could be in these substances to cause this. For the high school student your need to research the acidic values of each liquid you used to determine its ph and acidic strength. If this is for 7th grade or a middle school science project just showing that eggs protected with fluoride were protected may be satisfactory enough or to state that one substance is strong enough to eat up the shell. Was the fluoride effective in protecting the outer coating?

Hope you find this 7th grade science project useful and get a good grade. Remember it is what you put in it.

3rd Grade Science Projects Made Fun & Easy

There are plenty of third grade science projects that will be fun for your child to do. Kids this age love to learn new things and find out answers to questions on their own. Encourage them to choose a topic that interests them so it will be fun for them and they will see it through until the end. If they choose a topic that bores them, the parent may end up doing the majority of the work and that’s not good for the parent or the child. One fun project might be to see if everyone in their class has the same size feet and hands. All you need for this project is some paper and markers, then trace each child’s hands and feet, and then compare them with the rest of the class’s tracings.

Another fun project is to see if cut flowers last longer in cold water or warm water. All you need for this project is some white flowers, like carnations, some water, food coloring and two vases. Fill one vases half full with warm water and add some food coloring, then fill the other half full with cold water and add some food coloring. When finished, put one flower in each and see what happens. Do flowers drink warm water faster, slower or at the same rate as cold water?

No science project has to be complicated, just interesting. As long as you use your imagination, you will come up with plenty of third grade science projects.

Ten Interesting Things About Water

Water may seem the most basic of things on our planet, but it is also one of the most important. Here are ten interesting things about water to quench your thirst.

When considering water, it is important that you do not take it for granted. When you compare our planet to all the others we know of, we are the only body that has life on it. What is the reason? We are the only one with water!

1. Water is the most common substance on earth with 70 percent of the earth’s surface covered with water. There are roughly 326 million cubic miles of water on earth.

2. There could be no life without water. Every living thing is made of at least some water. Roughly 60 percent of our body is water.

3. A cow must drink roughly four gallons of water to produce one gallon of milk.

4. Humans consume over 16,000 gallons of water during their lifetimes. Water carries out life processes in everything. It controls biological reactions and serves as a remedy for digestion of other nutrients.

5. 97 percent of all the fresh water on the planet is trapped in glaciers, particularly in Antarctica.

6. Less than 1 percent of the water treated by public water systems is used for drinking and cooking. A quarter of the world’s population is without safe drinking water.

7. The natural rotation of the Earth has been slightly changed by some 10 trillion tons of water stored in reservoirs over the past 40 years.

8. You can live for roughly a week without water, but you can live for 30 days or more without food.

9. Water absorbs infrared radiation, which gives a blue tint to large bodies of water such as lakes and oceans.

10. Water has a high surface tension due to a strong bond between the atoms comprising it. As a result, things float on water that otherwise should not based on basic physics. To see this, take a pan of water and place a paper clip on it. Note that it floats and ridges of surface tension around its edges. This is also why you can slightly overfill a cup with water without it spilling.

Water is one of the fundamental building blocks to life on our planet. As these items show, our planet would be a barren rock without it and we would not exist.

113 Facts About Animal Cruelty

Animals caught in traps can suffer for days before succumbing to exposure, shock, or attacks by predators.
Traps often kill “non-target” animals, including dogs and endangered species.
To cut costs, fur farmers pack animals into small cages, preventing them from taking more than a few steps back and forth.
Crowding and confinement is especially distressing to minks- solitary animals who occupy up to 2,500 acres of wetland in the wild.
The frustration of life in a cage leads minks to self-mutilate- biting their skin, tails, feet- or frantically pace and circle endlessly.
“PETA investigators witnessed rampant cruelty to animals. Workers beat pigs with metal rods and jabbed pins into pigs’ eyes and faces.”
Snakes and lizards are skinned alive because of the belief that live flaying makes leather more supple.
Piglets are separated from their mothers when they are as young as 10 days old.
Once her piglets are gone, the sow is impregnated again, and the cycle continues for three or four years before she is slaughtered.
Approximately 3 to 4 million cats and dogs- many of them healthy, young, and adoptable- must be euthanized in animal shelters every year.
Cows produce milk for the same reason that humans do- to nourish their young – but on dairy farms calves are taken away at 1 day old.
1 day old calves are fed milk replacements (including cattle blood) so that their mothers’ milk can be sold to humans.
Animals can suffer brain damage or death from heatstroke in just 15 minutes. Beating the heat is extra tough for dogs.
Each year, approximately 10,000 bulls die in bullfights.
Most cows are intensively confined, unable to fulfill their most basic desires, such as nursing their calves, even for a single day.
Cows are fed unnatural, high-protein diets-which include dead chickens, pigs, and other animals.
Overall, factory-farmed animals, including those on dairy farms, produce 1.65 billion tons of manure each year.
Kid goats are boiled alive to make gloves.
The skins of unborn calves and lambs – some aborted, others from slaughtered pregnant cows – are considered “luxurious.”
About 285 million hens are raised for eggs in the US. In tiny spaces so small they cannot move a wing.
The wire mesh of the cages rubs off hens feathers, chafes their skin, and causes their feet to become crippled.
Before 1986, only four states had felony animal cruelty laws.
Glue traps cause terror and agony to any animals who touch them, leaving them to suffer for days.
In one study, 70% of animal abusers also had records for other crimes.
Sealers often hook baby seals in the eye, cheek, or mouth to avoid damaging their fur, then drag them across the ice to skin them.
Arsenic-laced additives are mixed into the feed of about 70 percent of the chickens raised for food.
Every year, nearly a million seals worldwide are subjected to painful and often lingering deaths, largely for the sake of fashion.
Scientists estimate that 100 species go extinct every day! That’s about one species every 15 minutes.
Every year in the US, 50 million male piglets are castrated (usually without being given any painkillers).
More than 15 million warm-blooded animals are used in research every year.
The methods used in fur factory farms are designed to maximize profits, almost always at the expense of the animals.
To test cosmetics, cleaners, and other products, hundreds of thousands of animals are poisoned, blinded, and killed every year.
In extremely crowded conditions, piglets are prone to stress-related behavior such as cannibalism and tail-biting.
Farmers often chop off piglets’ tails and use pliers to break off the ends of their teeth- without giving them any painkillers.
For identification purposes, farmers cut out chunks of young pigs ears.
Animals on fur farms spend their entire lives confined to cramped, filthy wire cages.
For fur, small animals may be crammed into boxes and poisoned with hot, unfiltered engine exhaust from a truck.
Engine exhaust is not always lethal, and some animals wake up while they are being skinned.
Larger animals have clamps attached to or rods forced into their mouth or anus so they can be painfully electrocuted.
Bird poisons attack birds’ nervous systems, causing them to suffer seizures, erratic flight, and tremors for hours before dying.
If you drink milk, you’re subsidizing the veal industry.
Male calves are often taken away from their mothers at 1 day old, chained in tiny stalls for 3-18 weeks, and raised for veal.
After they are taken from their mothers, piglets are confined to pens until they are separated to be raised for breeding or meat.
Although chickens can live for more than a decade, hens raised for their eggs are exhausted and killed by age 2.
More than 100 million “spent” hens are killed in slaughterhouses every year.
Forty-five states currently have felony provisions for animal cruelty. (Those without are AK, ID, MS, ND and SD.)
Dogs used for fighting are chained, taunted, and starved to trigger extreme survival instincts and encourage aggressiveness.
Dogs that lose fights (or refuse) are often abandoned, tortured, set on fire, electrocuted, shot, drowned, or beaten to death.
Cows on average product 16 lbs of milk per day. With hormones, antibiotics, and genetic manipulation? 54 lbs a day.
Humane treatment is not a priority for those who poach and hunt animals to obtain their skin.
Alligators on farms may be beaten with hammers and axes, sometimes remaining conscious and in pain for 2 hours after skinning.
Investigation of animal abuse is often the first point of social services intervention for a family in trouble.
A Canadian Police study found that 70 percent of people arrested for animal cruelty had past records of other violent crimes.
Dog fighting and cock-fighting are illegal in all 50 states.
Hoarding of animals exists in virtually every community. Well-intentioned people overwhelmed by animal overpopulation crisis.
The consequences for hoarders, their human dependents, animals, and the community are extremely serious- and often fatal for animals.
Declawing is a painful mutilation that involves 10 amputations – not just the nails – but the ends of toes (bone and all).
The long-term effects of declawing include skin and bladder problems and the gradual weakening of cats’ legs, shoulders, and back.
Declawing is both painful and traumatic, and it has been outlawed in Germany and other parts of Europe as a form of cruelty.
Kangaroos are slaughtered by the millions every year; their skins are considered prime material for soccer shoes.
Across the US, 6 to 8 million stray and abandoned animals enter animal shelters every year, and about half must be euthanized.

The sheer number of animals killed makes it impossible for pigs’ deaths to be humane and painless.
Because of improper stunning, many hogs are alive when they reach the scalding hot water baths.
13% of intentional animal abuse cases involve domestic violence.
Animal cruelty problems are people problems. When animals are abused, people are at risk.
Instead of improving conditions for animals, the dairy industry is exploring the use of genetically manipulated cattle.

If he has withdrawn from you, is not as affectionate as he once was, won’t spend personal time with you and has stopped being intimate with you, those are definitely red flags. If he is preoccupied with his cell phone – texting and reading texts, then you are right to think, “I want to read my husband’s text messages”.

What you will need to do is wait for a time when he is out of the room and pre-occupied with something else. A good time is when he is in the shower, because you know he will be in there for a certain amount of time. Find his cell phone and take a good look at it. There should be a history section with “sent” and “received” calls and texts. Be ready for what those messages might say, because just thinking “I want to read my husband’s text messages” may not prepare you for what you find.

How To Tell If Your Husband Is Cheating On You

Have you ever wondered if your husband is cheating on you? Has he cheated on you before and are you wondering if he is cheating on you again?

One grim reality that a lot of women don’t want to face is that any husband can cheat on their wives. This statement runs counter to romantic notions of faithful and singular love, but evidence from countless years of observation indicate that it is true.

The smart wife will take this fact with a grain of salt and keep her eyes open for signs of cheating. The first clear sign is usually easy to spot if you have been paying attention. This has to do with sudden changes of routine. For instance, is he coming home later than usual or leaving the office for extended periods of time.

The sudden onset of overtime is usually what first leads most wives to suspect their husbands of cheating. But from there, a lot of wives are afraid to go any further. They think up of rationalizations to convince themselves that their husbands aren’t going astray. They close their eyes to other signs until the truth is blatantly staring them in the eyes. Most wives are uncomfortable playing the role of detective and snooping on their husbands. On this regard, psychologists advice wives to start gradually. Begin with the obvious, they counsel. Check his car for signs such as strands of hair that don’t belong to you. Check his shirts for lipstick stains. Make a conscious effort to check if he has the smell of an unfamiliar perfume.

Keep your eyes and ears open. Does he suddenly take frequent business trips that take him away for days or weeks? Does he usually say that he’s tired or that he’s had a long day when he comes home from the office and you want to speak with him. Does he evade direct questions or have difficulty looking you straight in the eyes when he tries to answer them? If the answer is yes to any or all of these questions, chances are that he is indeed cheating on you.

Other signs include frequent phone calls on his cell, frequent calls at home where the caller hangs up when you answer, late-night phone calls that make your husband move to the next room, going online late at night when you’ve gone to bed, suddenly dressing better on a regular basis, carrying a condom when you’re on the pill, sudden changes in your sex life, say, he suddenly feels uncomfortable of is suddenly more aggressive or passionate.
