For this compounds worksheet, high schoolers identify molecules as compounds and provide a reason why they believe it is or is not a compound. Students write out chemical formulas. This worksheet has three problems to solve.

In this titration learning exercise, students determine the number of moles of an ion present in given solutions. Students calculate the relative formula mass and the concentrations of ions for solutions. This learning exercise has seven...

"By the hair on your chinny-chin-chin, I'll huff and I'll puff and I'll blow your house in," says the big, bad wolf! Engineering hopefuls are challenged to design and construct a hurricane-proof building from simple office and craft...

Explore Snell's Law using thin films. In the fifth installment of a seven-part series, pupils solve a set of problems relating to Snell's Law and use this skill during an experiment requiring the collection of reflective measurements...

Learners investigate why theoretical probability doesn't always match reality. The activity involves using Python 2.7 (or Sage) to set up a Bernoulli Trial. It also involves setting up a spreadsheet to simulate the Birthday Paradox....

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

Ron Toomer, a famous roller coaster designer, suffered from motion sickness. Pupils design their own roller coasters, learning about potential and kinetic energy in the process. Labs focus on the importance of drop height, energy...

It's time to slow your roll! Can your class create a track that allows a marble to roll as slowly as possible? Teams of science scholars collaborate to design, build, and test their tubes while learning about gravity and friction.
