Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

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...

As the title suggests, this is a simple summary of fossil fuels. There are no questions or problems to solve or no notes about fossil fuels. The notes cover how fossil fuels are formed, how we extract them, what humans use them for, and...

Historians believe the first vertical water wheel was invented in Rome during the Augustan Age. The sixth lesson in the series of 10 has scholars experiment with designing their own water wheels. Through testing various pastas and...

In this pH instructional activity, learners describe acids and alkalis. They also determine whether substances are strongly acidic or alkaline. To determine the pH of given substances, learners use the color of universal indicator paper....

For this chemical bonds learning exercise, students determine how much energy is needed to break bonds. Students classify reactions as exothermic or endothermic and identify a reaction as reversible. This learning exercise has four...

In this titration learning exercise, students calculate the moles of acids in a given amount of solution, balance equations, and calculate the concentrations of given acids. There are 10 problems to solve.

For this instructional activity about elements, students review the electron configuration of given elements and then complete the electron diagrams for the transition metal elements. This instructional activity has five problems to solve.

For this pH worksheet, high schoolers determine how indicators work and what the pH scale is used for. Students learn what happens when non-metals burn in air and metal oxides dissolve in water. This worksheet has 10 problems to solve.

In this activity, learners review the definitions of acids, bases, and salts. They also describe the differences between acids and alkalis and define neutralization. This activity has two short answers and one problem to solve.

In this chemical reactions learning exercise, students practice writing chemical formulas, word equations, and symbol equations. They also identify the types of reactions. This learning exercise has seven problems to solve.

For this compounds worksheet, students 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.

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.

In this fertilizer worksheet, high schoolers read background information about how farmers began using nitrogen compounds as fertilizer and how Fritz Haber developed an efficient process. Based on their reading, students complete 10...
