What a Drag!
Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.
Curated OER
Universal Proportions: Earth and Moon
Students create scale models of Earth, the Moon, and the distances within the universe. Working in groups, they construct their models of Earth and the Moon on a scale of 50:1 and calculate how far apart to place their models. They...
Curated OER
How Big Are Earth, Sun, and Moon?
Third graders draw what they believe is in space on a dry erase board. In groups, they are given a beaker half filled with water and they add a teaspoon of oil, observing the different layers that form. To end the lesson, they identify...
Curated OER
Are You a Golden Ratio?
Young scholars explore the concept of the golden ratio in nature and architectural design. They discuss examples such as petals on a sunflower and the Parthenon. In small groups they take turns measuring their body parts to find a...
