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
April 29th, 20103rd Grade Science Fair Projects and Ideas
April 14th, 2010
3rd grade science fair projects are a lot of fun because at this age children are eager to explore the world around them and find out how things work. They are constantly wanting to know the answer to the question “What happens if I do this…” and therefore they will likely come up with many different experiments they’d like to try. It may be difficult to decide on just one!
At this age they have a short attention span though, so the projects must be simple, fun and fairly short. There are many, many different project ideas for this age group such as; do all the children in their class have the same size hands and the same size feet as each other? They can research this by tracing the other children’s hands and feet on a piece of paper and comparing them to each other.
They could do a test to see if waterproof mascara is really waterproof. To do this you would need a couple brands of waterproof mascara, a piece of paper and some water. Simply put the mascara onto a sheet of paper and rinse it under some water to see what happens.
Another fun 3rd grade science project would be to see if raw eggs and hard boiled eggs spin the same number of times. Obviously they would need an adult’s help with this one in order to cook the eggs, and then they simply need to spin each egg and record the results. There are lots of great 3rd grade science projects out there; it’s just a matter of finding one that interests them.

Science Project Ideas
April 2nd, 2010
Science Project Ideas are sometimes hard to come by. When your child comes home from school usually in January or February and says, hey Mom and Dad my teacher sent home this note that we have a science project due in three weeks. Here are the details of what we need to do and here is a project board.
You suddenly feel overwhelmed. You were just getting back on track from the Holidays and are dealing with beginning of the year issues like tax preparation and finalizing out end of year work issues. Now you have to help your child find a science project that is interesting enough, creative and unusual, but yet unique enough so that it will not be like the other students science projects at school.
Also children have a tendency to rely on their parents to help prepare much of the project. No matter how much we try we have to help in some capacity.
Here is a science project idea that is simple and easy and that you child can do himself or herself. Depending on the age of your child you will need to supervise them because it uses matches which will need to be lit and batteries.
This science project will also be a great demonstration at a science fair where students need to present their idea and information about why it works.
For this science project idea you will need only three things.
A glass
Matches
2 AA Batteries
You are going to tell everyone that water will burn.
Fill the glass with water.
Drop the batteries in the water and leave them in the water for 30-40 minutes.
Remove the batteries.
Now light a match and hold over the water. The water should ignite and burn inside the glass.
Why does the water light and burn? Did the batteries leak or what energy is been put into the water?
Make sure your child researches those questions above to find the answers. I know you probably want the answers but we provide science project ideas. The kids still need to research why something works the way it does. That is why we make them do a science project so they can research and learn.
