Naming Binary Covalent Compounds
In this compounds worksheet, students read how to name binary covalent compounds and then practice by naming 10 binary covalent compounds.
Curated OER
Is it Ionic?
In this ionic compounds activity, students are given clues about compounds such as their physical and chemical properties in order to determine if they are ionic compounds. Students indicate which compounds are ionic and which are not.
Curated OER
Synthesis Reactions
Tenth graders write and balance chemical equations and make a PowerPoint presentation on synthesis reactions.
Curated OER
Mixing Colors
Fifth graders perform experiments with color mixing and color changing. They observe the differences between physical and chemical changes and record their observations in journals.
Curated OER
Acid and Base Testing
Students study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.
Curated OER
ECOLOGICAL BIOASSAY OF COPPER SULFATE IN DAPHNIA MAGNA
Students use this lab as a follow up to the introduction of the ecosystems and productivity levels, bioassays and what and how they measure, and Daphnia magna as an index organism, i.e., a species whose health within an ecosystem...
Curated OER
Rusting: A Form of Oxidation
Students observe and record the corrosive nature of oxidation-reduction reactions, and determine the electro-chemical series of selected metals.
Curated OER
Mass To Mass Problems
In this chemistry worksheet, students engage in a series of chemical problems that are associated with comparing mass to mass. The answers are included.
Curated OER
Identifying Wetlands
High schoolers describe three major categories of indicators that are used to delineate wetlands. In this wetlands lesson students visit a wetland and make observations then complete an activity using the soil.
Curated OER
Toxics Lesson Plan
Students discover that chemicals and toxics are all around us and we can make a choice whether or not to use them.
Curated OER
Periodic Behavior of Oxides
High schoolers investigate the properties of oxides and observe their periodic trends. In this behavior of oxides lesson plan, students experiment with metallic oxides and non-metallic oxides to determine if they are acid, basic or...

Enzymes Help Us Digest Food ~ Introduction to Sugars and Enzymes
After an explanatory introduction to sugars and enzyme activity, biochemists discover whether lactase is needed to digest lactose, sucrose, and milk as a whole. High school science lab skills are required for these investigations.

Condensation
It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Dissolving Different Liquids in Water
Not many youngsters realize that solids aren't the only materials that can possibly be dissolved in water. During this investigation, they find out that some liquids can dissolve in water as well. This is part of a unit on solubility,...
American Chemical Society
Temperature Affects the Solubility of Gases
Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...
