Curated OER
Individual Gas Laws
Students learn the relationships between the different properties of a gas and use previous knowledge and make predictions. They predit and explain certain phenomena of gases using their chemical knowledge.
Curated OER
Gas Law Problems
For this gas law problems worksheet, students research and answer nineteen unique questions associated with gas laws. Students work in pairs to answer the twenty questions asked.
Curated OER
Liquid Crystal IR Detector
Students experiment with one method of detecting infrared radiation. They simulate the detection of infrared radiation using a liquid crystal sheet.
Curated OER
Solids, Liquids, and Gases
In this chemistry element worksheet, 7th graders complete three pages of activities that help them learn about solid, liquid, and gas forms.

The Engineering Place: Balloon Flinking [Pdf]
A lesson and activity sheet on buoyancy. Students add weight to a helium-filled balloon to keep it suspended so that it won't float or sink, but instead will 'flink.'
