Can Photosynthesis Occur at Saturn?
In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Monitoring the Body's Reaction to Stress
When stressed, do you prefer the fight or flight response? Scholars observe, measure, and identify the body's response to stress using a well-researched methodology. They learn about the autonomic nervous system, hormones, and more.

Making Fossils
Third graders examine the differences between cast and mold fossils. They discuss geological time and how many fossils are millions of years old, then create a cast fossil using clay and a shell, and a mold fossil using a shell and...
Curated OER
Periodic Pigment
Students make paint using the ingredients from recipes from the 17th century. In this paint making lesson plan, students follow a recipe with vegetable oil, eggs, pigment, paintbrushes, and more to make their paint.

Designing a Water Treatment Plant
How does dirty water get clean enough to drink? After viewing a PowerPoint that outlines the process water goes through at a water treatment plant, groups work together to design a chlorination chamber for a treatment plant.
Curated OER
Oxidation and Salt
Students study the reaction on iron in water, air, and sodium chloride. They create a situation that shows this process and gives them the opportunity to hypothesize what, why, and how. They keep records and do an oral and written ...
