Curated OER
An Introduction to Acids and Bases
Investigating pH is intriguing, especially with these activities designed for an introductory chemistry or physical science class. Pupils use litmus paper to distinguish acids and bases and then make indicators from food products. They...
Curated OER
Factors that Affect Reaction Rates
Collaborating chemistry pupils observe that temperatrue increases the movement of dye throughout water, stirring increases the dissolving rate of sugar cubes, and concentration of solutions increases the chemical reaction rates. These...
Curated OER
Catalysts and Enzymes
Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...
Curated OER
Todd Duncan: The First Porgy
High schoolers view a video and conduct research about Jim Crow laws and their effects on race relations.
Curated OER
Example of Convection
Compare the density of different salt solutions and then observe currents that are caused by the difference. Set up a demonstration of dynamic equilibrium. The intent with these activities is to begin building understanding of density...
Curated OER
Construction of Food Chains and Tracing Energy Changes
If you need a few basic activities for teaching food chains to your emerging ecologists, here they are. Three sheets of organism cards are included for learners to cut out and arrange according to trophic relationships. To make the most...
Curated OER
Trophic Pyramids and Levels
The bulk of this lesson involves the construction of both an aquatic and a terrestrial ecosystem in which to observe trophic relationships. Detailed directions are provided, as well as discussion questions, and assessment activities....
Curated OER
Populations
Take your ecology aces out in the field to practice population counts and model the benefits of camouflage. Though not particularly exciting, these activites and the assessments that are also included are practical and applicable to your...
Curated OER
Models of Chemical Families
A simple activity for introductory chemistry classes is thoroughly explained in this lesson plan. Each individual receives a sealed box containing an unknown object. Inquisitors use indirect evidence to draw conclusions. This activity is...
