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.

PhysicsQuest

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.

Planck Scale

My 7 year old son Ben (who is sitting next to me now) has recently become interested in how small things can be. He is not convinced that nothing can be measurably smaller than a Planck length because whatever is Planck sized can always be divided into something smaller.

He thinks perhaps Planck lengths can be divided into energy beams that then become infinite.
