Ask & Experiment

Ask & Experiment has experiments for you to try at home, activity books to download, PhysicsQuest resources for your school or after school group, and a way you can get your physics questions answered by real physicists.


HenriPhysicsQuest, a free competition for 6-9th grade students and after school groups, consisting of four science experiments that give students clues to solve a mystery. Classes can submit their answers online and be entered in a random drawing for prizes. PhysicsQuest kits are free to registered classrooms and groups.

This has become a bone of contention in an otherwise ideal marriage.
