Identification of Different Compounds and Substances
High schoolers conduct a series of tests to identify unknown compounds. In this chemistry activity, students compare the physical and chemical properties of substances. They collect data and formulate a conclusion.
Curated OER
It's All About the Roots
Students investigate the process of hydroponic agriculture. They grow beans in different hydroponic solutions, compare results and graph their observations.
Curated OER
Wetland/Estuary Structure and Functions
Students plant wetland plants in aquatic soil and regular soil. They test the effect fertilizers have on each and record the chemicals found in run-off water collected from each soil sample.
Curated OER
The Effects of Temperature on Chemical Mixtures
Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.
