Water and Penny Experiments


-many pennies
-eye dropper
- clear drinking glass


One Experiment

1. Take the glass of water and fill it all the way to the top.
2. Carefully add pennies into the water one at a time. Does the water spill over immediately? How many pennies can you add before the water spills over?

Second Experiment

1. Put a penny on the table.
2. Take an eyedropper and begin dripping water on the surface of the penny. How many drops of water can fit on a penny? More than you think!

Another Science Project

Materials You Need

1. spoon
2. blank sheet of white paper
3. pencil
4. matches (Be careful, you might want to help your child handle these.)
5. beaker
6. glass
7. glass stirring rod
8. potassium or sodium nitrate (you can buy this chemical from science companies)
9. Camera or video recorder

Procedure (instructions)

1. Take the glass beaker and pour one cup of water into it.
2. Take the potassium or sodium nitrate. Measure out about one half of a teaspoon. Pour it into the beaker.
3. Use the glass stirring rod and stir until all the chemicals dissolve in the water.
4. Keep adding one half teaspoons of the chemicals to the beaker. Stir using the rod. When the chemicals stop dissolving in the beaker and begins to build up on the bottom, it is time to stop. You now have your solution ready.
5. Take the blank sheet of white paper. Dip your glass stirring rod into your solution. This solution is now your “ink.” Draw! Draw any design you want on your paper. Don’t be afraid to overuse. Make sure your lines are thick with solution.
6. Using a camera, take a picture of your paper, still wet from your sketching.
7. Let the paper dry a bit.
8. Before the lines of the solution disappear, take the pencil and mark an area of the drawing.
9. Now it is time to record our results. Have someone start the video recorder. Focus it on the drawing.
10. Take a glass and fill it up with water. Have an adult strike a match. Hand the glowing tip to the child. Get ready!
11. Have the child touch the spot on the paper that was marked with the pencil.
12. Film what happens! Take pictures. Get before and after shots of the paper to put on the science project board.

4th Grade Science Experient

In order to do science projects for the 4th grade, you first need the materials. Here is a list:

-pH paper
-lemon juice
-two see through glass containers
-magnifying glass
-glass or plastic vial
-nylon stocking or one leg of pantyhose (Don’t get alarmed! It’s for the experiment!)

Now it is time for the Procedure:

1. First cut up the coat hanger into one long metal wire. Be careful. Then take the wire and make a circle with an 8 inch diameter.

2. Take the stocking or pantyhose leg and stretch the opening top around the 8 inch wire. Staple it in place.

3. Cut off the end of the stocking or pantyhose (where the toes are). The take the vial and put it into the new hole that you just made. Make sure the vial opening is in the stocking/pantyhose. Use tape to secure the vial in this position.

4. Now it’s time to go outside! Take your new “net” and go to a pond, stream, lake, beach or ocean. Holding the wire part of the “net,” drag the net in the water. You are now collecting plankton, tiny microscopic organisms that you will use in your experiment!

5. As you drag the net in the water, plankton should be collecting in the vial. Pour the water in the vial into one of your two glass containers. Use a magnifying glass to look for plankton. Then go collect more plankton. Make sure you have enough plankton for your two containers. You want to have equal amounts of plankton in each container.

6. Everyday, add a tablespoon of lemon juice to ONE of your containers. At the end of the day, test the pH of each container using your pH paper.

7. Record these pH readings everyday. Also note how much plankton are in each of the containers everyday. Take pictures. Write down your observations.

8. After a week, your experiment is finished! What happened? Compare the plankton and pH readings of both containers.

Part II of the 5th grade science fair project

Now for the continuation of the 5th grade science fair project idea.

Next are the Results:

Take a photograph of the jars. Better yet, bring the two jars into class. Describe with a few sentences what happened to the different liquids that were poured into the jars. Compare the objects in the first jar and the second jar. Write down what happened in sentences.

And now for the Conclusion:

The liquids form different layers because they have different densities. Materials denser than a liquid will sink in it. Materials that are less dense will float.

Now that we know the conclusion, we can write a purpose:
What happens when you mix oil, water and honey?

A Great 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: You should do this part last. Come up with your own title!

Materials: For this 5th grade science fair project idea, you will need

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


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