From Polymers to Bioplastics: Looking Toward Finding Renewable Resources
Students investigate the properties of polymers. In this chemistry lesson, students explain the importance of energy sources. They produce a bioplastic from the lab and evaluate its structural integrity.
Curated OER
Engineering
Students examine how Shell uses engineering. In this engineering principles lesson students visit a web-pages, answer questions, and examine the ways that engineers go about exploring different ideas.
Curated OER
Putting on Mass: Just how do Trees grow?
Learners articulate an explanation of photosynthesis. They identify problems they have with comprehension of how a plant gains mass. Students describe a historical experiment.
Curated OER
Related to Natural Products
High schoolers examine how the microwave delivers energy at different power levels. They work together to complete experiments on various materials and different power levels. They answer discussion questions to end the lesson.
Curated OER
Einstein's BIg Idea
High schoolers discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.
Curated OER
Colored H2 Balloon Explosions
Students perform an experiment in which they put different types of salts in a balloon, fill it with hydrogen gas, and ignite it. The electrons in the salt molecules are excited by the heat and release energy in the form of light. ...
Curated OER
Plants and Air Purity
Students explore how green plants help improve air quality. They read an article and discuss the importance of air quality and its effects on the human body. They investigate by connecting hose to the top of a Bell jar and to a funnel....

Developing a Theory About the Nature of the Contents of a Sealed Box
Students observe the changes of a closed chemical system. They record and analyze the data as they manipulate the system. They answer questions to end the instructional activity.
Curated OER
Teaching about Aquatic Respiration
Students explore respiration in a lake ecosystem by experiment and research.
Curated OER
Car Engines
Students create piston systems and explore the conversion of linear to rotary motion that propels a car. In this motion lesson, students build and test a model piston/crankshift system and discover why there is a maximum limit to how...
Curated OER
Glass Transition in a Rubber Ball
Students illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect of...

Connect the Spheres: Earth Systems Interactions
Is everything really connected? Take your class on a walk outside, where they will make observations and write them down on a worksheet. Once they are back in the classroom, learners will work to determine if and how things like birds,...
Cornell University
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.
