Students construct rockets from balloons propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.
Students learn about stress and strain by designing and building beams using polymer clay. They compete to find the best beam strength to beam weight ratio, and learn about the trade-offs engineers make when designing a structure.
In a few minutes, with Code.org's simple drag-and-drop tutorials students can make their own Flappy game from any web browser or tablet, and share it instantly with friends. [1:33]

Students learn about applied forces as they create pop-up-books the art of paper engineering. They also learn the basic steps of the engineering design process.
How did Galileo figure out the mathematics of falling bodies? This video segment adapted from NOVA examines Galileo's work on motion. [4:00]
Students use water balloons and a length of string to understand how the force of gravity between two objects and the velocity of a spacecraft can balance to form an orbit. They see that when the velocity becomes too great for gravity to hold the spacecraft in orbit, the object escapes the orbit and travels further away from the planet.
In this fast-paced NASA Brain Bites video, an astronaut demonstrates the impact of microgravity on the use of tools in space. [0:47]
New York Times technology columnist David Pogue visits the Institute of Robotics at ETH Zurich, where materials scientists are designing a microbot that can travel into a human eye to treat a type of blindness. [2:49]
What is known about gravity? Find out Einstein's thoughts on gravity in a brief overview of this mysterious force.
This interactive activity from the NOVA Web site samples Galileo's experiments with falling objects, projectiles, inclined planes, and pendulums.
In this video adapted from NOVA scienceNOW, find out about the discovery of a new building material, the carbon nanotube, whose physical properties could theoretically enable the creation of a 22,000-mile elevator to space. [4:29]
Meet Nate Ball, a mechanical engineer who designs and builds devices that solve problems and even save lives, for example, vaccination devices for remote or disaster areas. He discusses what it's like to be an engineer, a robot project he is working on, and what he does for relaxation. [8:00]
To engineer Mary Frecker of Pennsylvania State University, origami holds the future for designing tools that could be used in fields such as medicine and space exploration. [5:55]
States the equation of Newton's law of universal gravitation. States the value of G and uses the equation to solve problems.
An interactive simulation that teaches about gravitational force, circular motion, and astronomy by manipulating the sun, earth, moon, and a space station to observe the effects of gravity and orbital paths. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional materials.
Move the sun, earth, moon, and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it.
Definition of gravity and how it relates to weight. Includes a video. [3:54]
