Curated OER
Projectile Motion II
Students explore projectile motion and kinematics in two dimensions. They determine, using an adjustable projectile launcher, what angle makes a projectile go the highest.

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...

Trebuchet Toss
Young engineers work in teams to design and build their own trebuchets according to certain criteria; they must be able to launch a mini marshmallow accurately into a pie tin. Background reading material, a planning sheet for trebuchet...
Curated OER
Aerospace Engineering
Twelfth graders examine the physics of rocket flight. They build and launch model rockets to measure their performances.
Cornell University
Catapults
Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome.

Marshmallow Catapaults
After a brief lecture on levers, torque, projectiles, and the five-step engineering design cycle, young physical science learners or engineers build catapults out of craft sticks. This is an open-ended exploration of what works and what...
Cornell University
Catapult
Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

Another Way of Factoring
Focusing on this algebra lesson, learners relate quadratic equations in factored form to their solutions and their graph from a number of different aspects. In some problems, one starts with the original equation and finds the solutions....
Curated OER
Air Movers
Students learn about Rube Goldberg machines (complicated devices designed to accomplish simple tasks and then design and build a machine that uses more than six separate steps to move an empty aluminum can. They can either work...
Curated OER
My Crazy Contraption
Fourth graders design a contraption, which contains five different examples of simple machines and works without intervention. They sketch designs and label its parts. They present their creations to the class and relate them to Rube...

Impact Craters: Holes in the Ground!
Students simulate crater formation through a lab activity. In this space science lesson, students calculate how much energy is transferred during meteorite impact. They identify different factors affecting the size and depth of craters...

Particle Models in Two Dimensions
In this motion worksheet, students draw and label the trajectory of objects including the x-component and y-component of the velocity. Students calculate acceleration and speed. This worksheet has 7 problems to solve.
