• ### 3...2...1...Puff! (rocket stability)

Lesson

Students learn about rocket stability by constructing and flying small paper rockets.

• ### Arm Model

Lesson

Students construct a model arm and learn how muscles and bones work together to achieve efficient movement.

• ### Balloon Blast

Lesson

Students devise a plan to measure the distance of a balloon’s flight, predict the direction a balloon will travel as it deflates, and learn about Newton's Laws of Motion.

• ### Center of Gravity

Lesson

Students learn about center of gravity and how the body adjusts to the force of gravity to remain balanced.

• ### Heavy Lifting (launching with payloads)

Lesson

Students design and build balloon-powered rockets with which to launch a payload to the classroom ceiling.

• ### Hero Engine (third law of motion)

Lesson

Students use the thrust produced by falling water to investigate Newton’s Third Law of Motion.

• ### Launch Altitude Tracker

Lesson

Students construct a launch altitude tracker and use it, along with basic mathematics, to indirectly measure the altitude achieved by their rockets.

• ### Newton Car (second law of motion)

Lesson

Students investigate the relationship among mass, acceleration and force, as described in Newton's Second Law of Motion.

• ### Paper Rockets - Advanced

Lesson

Students design and construct advanced, high-powered paper rockets for specific flight missions.

• ### Paper Rockets - Basic

Lesson

Students design and construct simple, three-sided rockets.

• ### Paper Rockets - Intermediate

Lesson

Students construct paper rockets, fly them using the launchers built earlier, evaluate their rockets' flight, and modify their designs to improve flight performance.

• ### Rocket Cars: Rocket Races

Lesson

Students learn about Newton’s Three Laws of Motion as they construct and test a lightweight “rocket” car propelled by the action/reaction force of air escaping from an inflated balloon.

• ### Rocket Launcher (for all paper rockets)

Lesson

Students create an air pressure launcher for use with their paper rockets.

• ### Water Rocket Launcher (teacher only)

Article

Instructions for building and operating a platform from which to launch water rockets used in student experiments.

• ### Water Rockets

Lesson

Student teams construct water rockets from empty two-liter soft drink bottles, and qualify their rockets for flight by conducting string tests.

• ### Wind Tunnel (performance tester)

Lesson

Students construct a wind tunnel to test the performance of their paper rockets, and use data generated from the test to help them design better rockets.

• ### X-51 Project

Lesson

Students apply rocket science principles to design, construct, test, and launch rockets using a real-world problem-solving simulation.

• ### Force, Motion, Friction and Energy
