Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive learning exercise. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific...

In this percent composition worksheet, students carry out an experiment to determine the percent of zinc in a penny. They write a balanced equation for the chemical reaction they performed with the penny and hydrochloric acid.

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

A series of math and science activities feature M&M's® as manipulatives to help kids work through equations. The resource includes exercises on finding averages, percent of compositions, moles in chemical reactions, genotypes and...

Seventy percent of the air pollution in China is due to car exhaust. Under the umbrella of environmental chemistry, learners extensively explore air pollution. From the makeup of our atmosphere to sources of major air pollutants, classes...

In this chemistry review worksheet, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.

For this biology worksheet, students determine how many solvent and solute molecules there are in the red blood cell and the IV fluid. Then they determine whether the IV fluid is hypertonic, hypotonic, or isotonic to the red blood cell.
