Curated OER
Observing Chemical Reactions
Start this series of lessons with a bang! Five exothermic reactions are outlined in this resource, including a demonstration that produces both light and sound. In the lab, chemistry apprentices record temperature changes, make hand...
Curated OER
Gas Pressure, Volume, and Temperature
Physical science learners conduct a simple experiment using the heat of their hands to affect the fluid pressure. They place a balloon atop a freezing cold bottle and observe what occurs as it warms up. Both activities demonstrate how...
Curated OER
Identifying and Explaining Reactions
Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...
Curated OER
Heat Energy Released or Absorbed in Chemical Reactions
Chemistry whizzes test the change in water temperature produced by a burning candle and the change in acid temperature produced by magnesium metal. With these two laboratory activities they explore heat produced during chemical...
Curated OER
Magnetic Induction
Physicists of the future observe the behavior of current in relation to a magnet through several inquiry activities. They construct a generator and experiment with solenoid coils. They learn and apply electromagnetic laws, most often...
Curated OER
Cellular Organelles
Wow! Separate organelles from the cells of dried peas. Observe vacuoles in beet cells. Watch protists in action. Examine SEM photographs. Beginning biologists get a complete exposure to the structure and function of cell organelles. Two...
Curated OER
Variations in Living Things
Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...
Curated OER
Starlight
An introductory exploration of the nature of light is provided via activities and demonstrations. Science superstars observe various light sources, learn how to apply inverse square law, and practice using a light meter. Follow-up...
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
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
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...
