In this half-life worksheet, students use a given table of half lives, mass, time and amount of original sample to solve for unknowns in nine given half-life problems.

In this pressure and kinetic theory learning exercise, students review Dalton's Law of Partial Pressure, the Kinetic Molecular Theory of Gases, and Graham's Law of Effusion. Students then solve 5 problems using these equations.

Symmetry, line, shape, art, and math are all connected through a fun hands-on craft. Included are instructions to a classic activity, where learners create butterflies to show symmetry in nature and then discuss symmetry in math. It is...

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...
