Good afternoon my son has a science project the category is physical science can you'll give me science ideas he can do i'm new to this

As a experiment you could use is The affect of light in plants. A study He can do is maybe about Gravity affects and how it works on weight. Also you can do a all time favorite the Mentos and Diet Coke Experiment.

Hopefully one of these ideas will inspire you!

scientific laws are the result of testing theories and proving them to be facts.
