Curated OER
Designing and Building Catapults
Seventh graders complete a challenge to create a catapult that projects a marble or other projectile at least one meter. While experimenting they apply the Four Question Strategy to answer the question, " How can I make one modification...
Curated OER
Build a Catapult
Studens construct their own catapult. In this history of catapults lesson, students work in groups to make their own model of a catapult. Students use physics vocabulary terms explain how the catapult works. Students test the catapults...
Curated OER
Levers: Catapults
Students construct a catapult that shoots a cotton ball at least two meters using Legos, rubber bands, and plastic spoons. They discuss how the catapult works, and identify any problems they had with their experiment.
Curated OER
Catapults!
Students work together to discover the relationship between the angle of catapults and the flight of different objects. They discover the heavier the object the more force is needed. They examine how engineers use this information to...
Curated OER
Simple Machines, Odd Machines
Students recognize and identify common objects that can be used as a lever. In this simple machines lesson, students experiment with materials to design and construct a machine that uses a lever. Students also design and build a catapult.
Curated OER
Science: Motion Commotion
Students examine Newton's three laws of motion to discover what causes it and how it changes. They conduct motion experiments by building catapults and constructing balloon rockets. Finally, they conduct peer studies correlating...
Curated OER
KS2 Forces and Motion
Young scholars participate in a variety of activities of scientific principles. In this science lesson, students experiment with spaghetti and marshmallows to build a strong structure, balance nails on a nail, and use force to catapult...
Curated OER
Fling It
Students investigate the best design using technology. In this science lesson, students construct a freestanding object with specific materials to be able to shoot a ping pong ball and a marshmallow. They have to adjust and discuss...
