Students experiment on Boyle's law using balloons and other common materials. In this chemistry instructional activity, students explain the relationship between pressure and volume. They solve problems relating to Boyle's Law.
Curated OER
Clouds
Third graders complete various activities about clouds. They create a cloud in a lab, write a cloud story, make a cloud model and complete a webquest.
Curated OER
Kites
Students build a kite while integrating math and science. In this kite building lesson, students construct a blueprint and apply mathematical formulas while constructing a kite. They use appropriate flight and kite terminology to...
Curated OER
Mass vs. Weight
Students explore physical science by conducting a measurement experiment. In this mass lesson, students identify the differences between mass and weight and define a list of other vocabulary terms. Students utilize electronic scales and...
Curated OER
Tree Identification
Students list four ways to identify trees. In this tree identification instructional activity, students use tree identification techniques such as leafs, bark, wood grain, soil type, and climate to create tables and graphs.
Curated OER
Monitoring Energy Expenditure
Students use heart rate monitors and complete a swimming and running test. These tests allow students to obtain personal data, to manipulate the data through calculations of various parameters, and to graphically represent the data.
Curated OER
Conveyor Belt Production
Students design a system that will move their glass product across a room in the plant. They must move the product 12 feet and their items cannot fall off at any time.
