Making soap you can use
Those textbook experiments are no good. Using this simple method you can make a real bar of soap. It's
Curated OER
Surface Tension (Soap Boat)
Students investigate the affect of soap and water temperature on surface tension.
Curated OER
Bubble and Boyle
Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...
Exploratorium
Bubble Suspension
Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity:
Carbon dioxide gas is more dense than air
Bubbles are semipermeable, allowing only carbon dioxide to diffuse...
Curated OER
Playing With Polymers
Students explore the world of polymers. In this chemistry activity, students make polymers and observe their properties. Follow-up questions and extension activities are included.
Curated OER
Why is My Honey Runny?
Students identify the factors that affect viscosity of substances. In this chemistry lesson, students define what viscosity is in their own words. They give real world applications of viscosity.
Curated OER
Water
Students conduct a series of investigations on the unique properties of water. In this general science activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.
Curated OER
States of Matter
Students discuss a given set of questions based on Chemistry and matter and review a glossary of terms. They conduct experiments on each state of matter: "Dry ice and water, Dry ice and soap and Dry ice and Isopropyl Alcohol." and...
