YAAAAWWWWNNNNN!!!! Well, now that I’m finally waking up from my Thanksgiving meal food coma, it’s time to talk about our good friend tryptophan. Oh come on, you know the stuff or at least you have heard about it.
Tryptophan is one of the 20 standard amino acids. It is also one of the essential amino acids [...]

We got together with one of our first course takers to show everyone how pulleys work… without using pulleys!

This experiment was written by 12 year old Michael R. from Florida, USA!
Daredevil egg
Background:
This experiment is used to observe another Newton’s second law, according to which the force applied is the product of mass times the acceleration produced in the object.
Problem:
To verify Newton’s Second Law by using a placemat, tube and egg.
Materials:
An [...]
