It’s time for the school’s annual science fair competition. Now that your child is older, what are some good 4th grade science fair project ideas? Magnets? Plants? Electricity? No need to worry, 4th grade science ideas are not that hard to come up with. Here is a sample project:
Materials Needed
-scissors
-spoon
-tape
-crazy glue
- nails (same length)
-medium size cardboard box
-balloons
-bowl
-bag of sugar
-two thin wooden boards (Make sure they have lengths/widths that are equal to or less than the length and width of the bottom of the cardboard box.)
Step by Step Procedure
1. Adult supervision might be required. Take one of the thin wooden boards and crazy glue/tape a nail right in the middle of the board. Put crazy glue/tape on the head of the nail and stick it on the board so the point side of the nail faces up.
2. Take the other thin wooden board. Glue and tape the nails in the same manner as the first board (pointy side up). Instead of one nail, take four nails and arrange them in a square shape in the center of a board. Make sure the nails are about the same height.
3. Take the cardboard box. Using scissors, cut off the top and one of the sides.
4. Place the one pined wooden board into the box. Make sure the nail is in the middle.
5. Blow up one balloon and put it lightly on top of the nail. Make sure to be careful. You do not want the balloon popping!
6. Take the lid of the cardboard box that you cut off with the scissors. Put it on top of the balloon.
7. Put the plastic bowl on top of the cardboard lid, right in the middle. The sole needle should be holding everything up.
8. Add one spoonful of sugar into the bowl. Watch what happens. Keep adding spoonfuls of sugar until the balloon pops. Record how many spoonfuls of sugar it took for the balloon to pop.
9. Now it is time for a different setup. Take out the wooden board with the one nail. In its place, put in the wooden board with four nails. Make sure the nails are in the middle.
10. Repeat the other steps. Blow up a balloon and put it on top of the nails. Put on the cardboard lid. Then put the bowl in the middle.
11. Add spoonful of sugar until the balloon pops. How many spoonfuls did it take this time?

4th Grade Science Fair Project Ideas

What are appropriate science projects for 4th graders? This is the question that you, the parent, might find yourself asking when your child brings home the annual science fair handout. Obviously, you cannot do the volcano every year. But what should you do instead? What kind of other projects are there? Don’t worry. You do not need to be a scientist to figure this out.
Here is one of many science projects for 4th graders:
Materials (what is needed for the experiment)
Adults might want to help the child handle some of the equipment.
-cup of muddy water
-cotton balls
-scissors
-tape
-plastic drinking straw
-clear vase
-paper towels
-electric drill
-an empty, liter soda bottle (plastic)
- rough gravel
-fine gravel
-large grained sand
-fine grained sand
-camera
Procedure
1. Adults might want to help with this step. Take the electric drill and drill a hole in the cap of the soda bottle. You want the plastic drinking straw to fit snugly into this hole. You can use tape to get the straw to stay.
2. Take the soda bottle and put it upside side down into the vase. (Enter the straw end first.) The straw should reach halfway between the top of the vase and the bottom of the vase.
3. Take scissors and cut the bottle of the soda bottle off. Make sure to get rid of the four protrusions that are commonly found on most soda bottles. With the bottom gone, you can now place things into the bottle.
4. Fill the neck of the soda bottle with cotton balls.
5. Now it is time to put our rocks into the bottle. First put in the coarse gravel. Then put in the fine gravel. Next comes the large grain sand. On top of that is the fine grained sand. And finally, all the way on top, layer some paper towels.
6. Take a picture of the glass of muddy water next to your man made filter. These pictures can be used in the results section.
7. Pour the muddy water into the soda bottle. Watch the water drip from the straw and into the vase. What color is it?
8. Time how long it takes the water to come through. Take pictures showing the results.
9. Using rocks, you have created a filter for muddy water! – And science projects for 4th graders!

Water is a very powerful force. Depending on where the water is running depends on the force and power it has. Here is a science project to show the force and power of water.
Get the following materials before you start the project.
A half gallon orange juice or milk carton An ice pick or a nail about the size of an ice pick Tape preferably masking tape Water A sink (no you won’t need to go get one but you will need to have a sink available to do the project) Scissors A Permanent market or pen Paper A ruler or tape measure
Instructions for project:
Using the ruler measure 7 inches from the bottom of the paper orange juice carton and make a mark. Do this on all sides. Now using the scissors cut around the carton along the marks you made so you know have a box 7 inches high. Now on one side only use your ruler and measure
