Organic Chemistry Problem Set Key
In this organic molecules worksheet, students solve nine problems involving reactions of organic molecules. They must draw and label reactions, explain the processes of the reactions and predict products of reactions
Curated OER
Convection Activities
Learners conduct a series of hands-on activities to demonstrate that heated air expands and that warm air rises because it is less dense.

Let's Take a Rock Apart!
Students examine a crushed rock and sort the minerals they find in that rock by color and other properties.
Curated OER
The Changing Landscape
Students examine the evolution of landscape painting in France from the 17th to the 19th century. They study and compare three landscape paintings, emphasizing space, depth, and the concepts of foreground, middle ground, and background.
Curated OER
Denaturing Proteins
Students investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to denature...
