To Float or Not to Float - A Lesson on Density
Students define density in their own words. In this physics lesson plan, students calculate density using mass and volume. They explain why some objects sink and some float.

CheMATHstry That Sticks Right to You
Young scholars find the percent composition of sugar in the gum. In this chemistry instructional activity, students calculate percent error from the experiment. They use dimensional analysis to convert between units.

Mystery Card 3
Students will make a circuit on a mystery card. They will connect wires, bulbs, and battery to form an electrical tester. After students learn how to make one following the directions, they can create their own mystery card by...
Curated OER
Mystery Card 2
Students make a circuit on a mystery card. They then use an electrical tester to determine where electricity flows between circles on the card. They will connect wires, bulbs, and a battery to form an electrical tester.
Curated OER
Mystery Card 1
Learners test their knowledge of electrical conductors and circuits by constructing an electric tester and using it to determine where electricity flows between circles on a mystery card.
Curated OER
Towel Testing
Students examine how to design and implement experiments. In this paper towel experiment activity students test the strength of paper towels.

Designing a Flotation Strategy for the Purification of Recycling
Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...
Curated OER
The Air Up There!
Students create a model of a column of air and discover one of the reasons why low and high pressure systems exist and why low pressure is often associated with bad weather.
Curated OER
Soil Comparison and Analysis
High schoolers perform tests on different soil samples. In this earth science activity, students classify the soil into groups according to test results. They write a lab report following a certain criteria.
