Learners balance chemical equations and solve for gram to mole ratios.

Students explore speed by calculating the average speed of several snowmobiles, and predicting which of them is the fastest. They watch a race to verify their calculations.

This isn't your typical basic lesson—it's more acidic! Learners use pH information to determine the hydroxide ion concentration of different substances and then use these values to analyze information. The calculations require...

Practice converting a conventional number into scientific notation, and vice-versa. Using an applet, they perform the operations of multiplication and division on numbers expressed in scientific notation.

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

Students investigate water usage at school and at home. They use graphs and tables to evaluate water usage. Students describe possible water conservation measures. They use graphs and tables to relate data as part of a written report.

In this star magnitude and multiplying decimals worksheet, students solve 5 problems using the magnitudes of given stars to determine which stars are the brightest, they determine the magnitude differences of stars and they sort given...

Students examine the relationship between the products they use and energy use. Using the internet, they identify the role that manufacturing plays in using energy and the emissions that change the climate. They discover the steps to...

For this chemistry 112 worksheet, students use their knowledge of chemistry concepts to answer the multiple choice questions provided. Students calculate the answers using the appropriate formulas.

Students work in groups to define chemistry vocabulary including the terms reactants, products, exothermic and endothermic. They then combine the group definitions to arrive at a consensus definition for the class. Students also listen...

Upper graders identify the major characteristics of a wetland. They explore the human factors that change a wetland and write a descriptive paragraph about wetlands. This comprehensive instructional activity also has an interactive...

Fourth graders investigate the principles and uses of gears, and examine how gears can be used to alter the direction of motion or the speed of an object. They observe two cars with different sized wheels roll down an inclined plane,...

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.
