Science fair projects for 5th grade

The science of machines never fails to fascinate kids. Alternatively, you could see if plants will grow if they are "watered" with liquids other than water. The key to developing a successful project is finding an idea that is interesting to a 4th grader. Write messages using different types of invisible ink. Investigate decomposition. Wow your students by layering colored sugar water as you learn about density, adhesion, and cohesion. Put different materials between a magnet and metal. You can try this project with ants or other crawling insects as well. You can try milk, juice, vinegar, and other common household liquids. Then you need some great hands-on experiments in your tool kit! The classic crystal experiment gets a new twist when you have kids shape pipe cleaners into their own names first. Create edible soil layer models, complete with gummy worms, for a simple earth science project. So pick up some supplies and get ready to blind your students with science! Is there a common trend or not?

Explode a Mentos geyser. Plastic seems incredibly modern, but people have been making casein plastic from milk for centuries. Put different materials between a magnet and metal. Learning about oceanography? Grow crystal names. Your students will truly feel like scientists when they perform this classic experiment.

Test seeds that sprout quickly, like radish seeds, and different microwave times, such as 5 seconds, 10 seconds, 30 seconds, one minute.

4th grade physical science projects

Use a control no microwave treatment for comparison. Water plants with a different solution of salt or sugar. A related question would be to see if plants can survive if they are watered with soapy water such as leftover dishwater. Grow bacteria in petri dishes.
