In this electricity activity, students read about electric charge, ionic notation, and conductors and insulators. Then students complete 19 matching, 6 fill in the blank, and 2 short answer questions.

In this chemical equations and symbols worksheet, students are given two written equations and they translate each into chemical symbols. They are given two equations with chemical symbols and they translate them into written equations.

Eighth graders define the pH scale, acids and bases. They distinguish between acidic and basic solutions using litmus paper. Students review simple chemical formulas. They define the subscript and coefficient in terms of chemical...

Students generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.

In this minerals and rocks worksheet, students answer questions about the chemistry of minerals, scratch tests, rocks and the rock cycle, and erosion and deposition.
