Does anybody know any 4th grade science projects?

Answer 1

Here are a few ideas:

1) It should be something that interests the student.

2) Is should be something the student can do on his or her own. Nothing kills your chances in a science fair faster than work that was obviously done by an adult.

3) Your experiment should enable the to answer a question he or she has posed. Keep in mind, no one expects a student to break new ground. Science is a methodology for answering questions about the physical world, and in the end the student is demonstrating to the judges that they understand that methodology.

Here are a couple of examples:
A) "What is the ideal amount of water to make plant seeds sprout?" You'll need several pots with equal amounts of soil, and a packet of seeds. Document the number of seeds planted in each pot, and at what depth. Put no water in one (completely dry soil) and increasing (measured) amounts in the others. The last one should have way too much water. Document which one sprouts first, and the height of hight of each sprout day by day as they grow. If you add any water after the plants sprout, you need to show when, and how much.

B) "Does relative humidity effect the amount of time it takes water to boil?" For this you need a source of heat that can be set to a repeatable level (like an electric hot plate), a cooking pot, a room thermometer and a barometer. Boil the same amount of water once or more each day, and make a note of the temperature and humidity each time, along with the amount of time. hopefully, you will have several data points that share the same tempurature, but different levels of humidity.

4) NO VOLCANOS!!!!

There is even a link to a forum by Janice VanCleve, science teacher who has written LOTS of fun science project books (available at most public libraries).

Answer 3

Depends what they're learning... can always do the plant one where you put food coloring in water and the plant in there and it takes 2-4 days but theplant changes color... celery happens right over night or in a couple of hours... OH! And the one where you duck tape two 2 liter bottles together, one filled with water and make a water tornado thing!!

Answer 4

When i was in 4th grade, i grew plants in a biodome and measured to see which was the tallest.

Answer 5

Do cookies, and make them a bunch of times leaving one ingredient out each time.
