Discovering Enzymes
Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.

WHAT MAKES A LIGHT BULB LIGHT?
Young scholars are able to use inquiry to answer the essential questions. They are able to predict and test configurations of a battery, bulb, and wire that make the complete circuit. Students craft a group and individual theory of a...
Curated OER
Enzymatic Action
Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...

Einstein's Big Idea
High schoolers investigate the concept of the Einstein's Theory of Relativity while conducting research using the internet and following the outline of the objectives to guide the information search. The lesson includes background...
Curated OER
Plant Pigments
Students investigate the components of chlorophyll. They use paper chromatography to separate the many pigments of chlorophyll from one another.
Curated OER
Unknown Element Project
Students work with a partner to determine the identity of an unknown element based on given descriptions. Groups use classroom textbooks, encyclopedias, and science internet sites to identify their unknown element then write a report as...

The Awful 8: A Play
Students perform a play that presents the causes and effects on people and the environment of the eight major air pollutants.
Curated OER
Air Pollution Word Search Activity
Students examine the issues surrounding air pollution. They discover how it affects peoples health and the government's regulations. They complete a word search activity to practice the vocabulary.
Curated OER
Using VNTR Analysis to Identify Guilt at a Crime Scene
High schoolers collect DNA from cheek cells. They compare and contrast the processes of DNA replication and PCR. They discuss how this information can be used to determine guilt at crime scenes.
Curated OER
Synthesizing Pigment and Dyeing Cloth
Students create a synthetic dye and oxidize the dye and record the effects.
Curated OER
Cytoplasmic Streaming
Students prepare successful wet mount slide of Elodea. They determine and identify environmental conditions that induce cytoplasmic streaming. They determine the positive aspects of cytoplasmic streaming. They illustrate knowledge and...
