Grow your Own Crystals Geology To begin this project you will need to boil water. This should be done by an adult or under adult supervision. While the water is boiling have the kids cut their sponges in small pieces or shapes of their choosing. Have each child place their sponge pieces in their own pie dish with a small separation between each piece of sponge. Once the water is boiled have each child mix one fourth cup of Epsom salt with one half cup of water. Do this part in a separate mixing bowl. When the Epsom salt and water are mixed the children can all add their choice of foodcoloring to their mixture. Make sure they only add a drop so they don't throw off the balance between the water and the Epsom salt. After they have colored their mixture each child can pour the mixture evenly over each of their sponge pieces. Once they have done that they should carefully place their pie dish on the windowsill or in another sunny location. The crystals will form as the water dissolves from the mixture. This will take several days. Have the children chart the progress of the crystal formation. The great thing about simple science projects such as this one is that you can change them up and make the outcomes different. This can be done by using different shapes of sponge. You can also take the sponge out of the equation and just fill the bottom of the pan with water. Another fun spin on this would be to do an experiment with and without the sponge at the same time.

Rusting Pennies For Science Chemistry Elementary School, Middle School First, you need to find two new, clean pennies, some orange juice and soda, and obtain two bowls or glasses to put the liquid and pennies in. Place a penny in each bowl or glass and fill one part way with orange juice and the other part way with soda. Wait about one week and then check the pennies. Do either one of them have any rust on them? They may not yet, and if they do not you will have to leave them for another week and check them again. Be sure to record your results! This project is a good one for people who have some time to complete their project. If you have a limited amount of time, then you might want to think of some other ideas fora science fair project that are a little less time consuming.

Plants Grow With Milk? Chemistry 4th The first thing you need to do is fill three different pots with potting soil, and put four or five seeds about one inch deep in the soil in the middle of each pot. You can then put a piece of masking tape on each pot and label them one by one; milk, juice and vinegar. Next, find a sunny place to put the pots, such as a windowsill, and place the pots side by side so they all get the same amount of sunlight. Then, water each one with the liquid assigned to it and repeat this process every other day until you notice one or more of the seeds beginning to sprout. Be sure to record your findings.

Tornado Formation Earth Science Elementary Earth science experiments can also take the route of weather formation in a safe way, of which tornados are probably the most intriguing for kids. The materials are also simple including a larger glass jar with lid, water, teaspoon, dish soap, food coloring and a few toy figures of houses, people or animals. Fill the glass jar until it is ¾ full. Add the food coloring and a teaspoon of the dish soap. Place the figures inside and tightly close the jar with the lid Shake the jar vigorously for 20-30 seconds Twist the jar and a tornado forms complete with the lengthening and contracting nature With these earth science experiments, any child can fully enjoy himself while at the same time gaining a respect for Mother Nature
