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. For 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
The Catapult
Students identify the advantages and disadvantages of a catapult as a weapon. In this physics lesson, students construct their own catapult. They investigate how changing one variable affects results.

Small Trebuchet
Travel back to medieval time where learning is just a stone's throw away! A video introduction shows a trebuchet (catapult-like machine) as it launches a rock into a lake. Learners use their quadratic modeling skills to predict the...
Curated OER
UFOs
Learners, in groups, construct a catapult. Then they conduct a series of experiments by catapulting a marshmallow, using different lengths of spoons, across the room. They predict, measure, and record the measured distance on a worksheet.

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
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...
Curated OER
KS2 Forces and Motion
Students 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 a...
Curated OER
Simple Machines, Odd Machine
Students construct a device to 'launch' a marshmallow at the teacher and then discuss various forms of levers. They work in teams to design catapults and identify different kinds of levers.
Curated OER
Elastic Forces
Third graders predict and experiment to discover the amount of force exerted by a stretched elastic band. They construct a spreadsheet and make a bar graph showing the results of their experiment.
Curated OER
Prosperity and Challenges
Young scholars watch a slideshow about the technological advances in agriculture. After viewing, they complete an index card about one aspect of the slideshow. In groups, they create a cause and effect timeline in which they identify...
Curated OER
Projectiles
Students measure the angle and distance of an arc. In this projectile lesson, students observe arcs created by water guns, bow and arrows, and slingshots, then work in small groups and use protractors and strings to measure the angle and...
Curated OER
Exterior Ballistics
Young scholars explore velocity and trajectory. Using exterior ballistics rules, students predetermine the path of an artillery shell. Given equations and the firing angle, young scholars determine the velocity and horizontal travel. ...
Curated OER
Angling for Distance
Explore the concept of projectile distance through determining the angle that will provide the maximum distance of a launched projectile. High schoolers launch baseballs on a football field and video tape the path of the ball.
Curated OER
Move It!
Third graders examine simple machines. For this simple machines lesson, 3rd graders observe simple machines at work in a video, then experiment with creating their own simple machines to move objects.
Curated OER
Don't Let Parabolas Throw You
Students identify relation, function, patterns and range. In this algebra lesson plan, students factor and graph quadratic equations. They use transformation to move the parabola around and make predictions.
Curated OER
Simple Machines, Survivor-Style
Students apply the principles of simple machines to create events in a wacky obstacle course. They work with a partner to prepare a visual presentation and an expository description of the obstacle course. Each group sequentially...
Curated OER
Simple Machines, Odd Machine
Students examine levers and design a machine that uses a lever as a central component. In this lever machine lesson students test various machine designs and evaluate their effectiveness.
