In this salts learning exercise, students read how salts are created and how different acids make different salts. This learning exercise has one graphic organizer and seven short answer questions.

In this anions activity, students are given a table showing nine anions, the test that indicates the presence of each anion, and what will be observed when each substance is added to the anion.

Students explore aquariums. In this fish and ecosystems lessons, students establish a freshwater aquarium environment using materials provided. Students read about and care for the classroom fish.

In this oxyanions worksheet, students identify the common polyatomic ions. They write formulas and name polyatomic ions based on IUPAC rules.

Students discover how temperature effects the solubility of solutes by experimenting with a range of temperatures. They develop skills for observing, inferring, measuring, comparing and contrasting.

Middle schoolers discover correlations in food preferences of invertebrates, and assess stream health through use of kicknets, invertebrate keys, CBL systems and probes.

Students take a virtual trip to a Catfish Aquaculture Pond and analyze soil bacteria to determine how many nitrogen cycle bacteria are present. They graph the number of colonies present and use data to determine ammonium levels in the soil.

Students investigate the factors that compose the nitrogen cycle. The harmful effects of acid rain and ozone depletion are also discussed in the lesson. Students define the nutrient that is often limiting to plant growth through...

Young scholars explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are...

For this stoichiometry worksheet, students practice calculating moles, molar mass, and percentage composition of given compounds. This worksheet has 55 problems to solve.

For this reactions learning exercise, high schoolers read about two types of reactions that take place between metals: displacement and competition. Then, they answer two problems.

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...

In this compounds worksheet, students name the given compounds from its chemical formulas and write the chemical formula from the compound name. This worksheet has

In this acid and base worksheet, students fill in a table with the type of acid or base and the symbol used in calculations. Types of acids and bases identified include strong acids, weak acids, strong bases, weak bases, Lewis acids, or...

For this acid and base worksheet, students fill in a table given acids and bases and identify the type of acid or base it is and the symbol used in calculations.

In this electrochemistry worksheet, students determine the voltage of a cell based on the reduction potentials. Students write a condensed cell diagram and the oxidation half reaction for the cell. This worksheet has 30 problems to solve.

In this compounds worksheet, students name the given ionic compound, describe how covalent compounds are named, and write the chemical formulas for the covalent compounds. This worksheet has 2 fill in the blank and 3 short answer questions.

In this chemical reactions worksheet, students balance an equation, determine the type of reaction, and write the net ionic equation. This worksheet has 5 problems to solve.

In this solubility instructional activity, students are presented with a table that shows the solubility of salts and hydroxides in cold water. The table shows which salts and hydroxides are soluble and which are insoluble.

Students identify patterns and relationships from data that is collected and solve variables.  In this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

Young scholars build a fish trap across a small stream. The purpose of the trap is to collect baseline data of Oncorhynchus kisutch, Coho salmon, smolt numbers coming out of a spring-fed pond. Other biological data also be measured.

Learners participate in a field and laboratory study to determine if local freshwater mussels are environmentally stressed.

Students experiment with local lake water to determine the health of the lake waters. They explore the human impact on the lake water, hypothesize and share inferences in a scientific report.

Students cuminate their study of molecular structure and bonding with this activity.
