Lead and Mercury Ion Catalase Inhibition
Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.
Curated OER
Evaporation of Alcohol and Water
Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.

Conservation of Mass
In this conservation of mass worksheet, students design an investigation to demonstrate the Law of Conservation of Mass. Students describe their investigation, collect data, graph the data and write a conclusion about what they discovered.

Activity #8 Which State Are You In?
Young scholars define, give similarites and differences between solids, liquids, and gases. They compare and contrast a solid, liquid and gas in terms of shape, volume, compressibility, diffusion and density. Pupils classigy common...

What Changes Occur When Water Freezes?
Learners investigate the changes that occur at the molecular level when a liquid becomes a solid. They freeze water in baby jars and observe the changes that occur in the process.

Melting and Freezing of Water
Students differentiate the three states of matter. In this chemistry lesson plan, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

You Light Up My Life: Developing a Scientific Theory for What Fuels a Candle's Flame!
Students examine how candles work and how scientific theories are developed and tested. Students propose hypotheses about what is burning in a candle then perform tests in order to develop their scientific theory. After a teacher...
Curated OER
The Same But Different
Third graders observe a frozen container filled with ice and discuss what happens when the ice sits out in the room. They practice measuring the mass and volume of the ice, watch as the frozen container is placed in a warm water bath to...
