Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

Experiment with the center of gravity by stacking blocks in a way that appears to defy its force. This is a fascinating demonstration that you can use when teaching about gravity, forces, or balance. 

Groups simulate an orbit using a piece of string and a water balloon. Individuals spin in a circular path and calculate the balloon's velocity when the clothes pin can no longer hold onto the balloon.

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

Host a design challenge of Olympic proportion! Junior engineers build their own bobsleds using simple materials. The activity focuses on kinetic and potential energy and how the center of mass affects motion on a downhill track....

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Scholars build a boat using an assortment of materials such as foam plates, aluminum foil, and skewers, then test its buoyancy with pennies. Challenge boat builders to construct the strongest or fastest boat in a healthy competition with...

Wrap up the unit in one final design. Pairs use their knowledge of aviation to design new flying machines and record how their designs take into consideration the forces that act upon airplanes. The pupils determine whether their designs...

Harness the awesome power of gravity. Scholars build a zip line to transport a ping-pong ball. The challenge is to get to the finish line in under four seconds. At that speed, individuals better be sure to strap on the harness!

Slide all the way to the bottom. Using the design process, pupils create a carrier for a ping pong ball that will travel down a zip line. Learners test their carriers and determine solutions to issues they encounter to complete the third...

Just how do astronauts stay safe during moon landings? Here's an activity that allows investigators to use the engineering process to explore how shock absorbers protect astronauts during landing. Applying knowledge of gravity, force,...

Toys are great for learning about physics. Scholars use Slinky® toys to study Newton's laws of motion and types of energy. After a little play, they then model longitudinal and transverse waves with the Slinky® toys.

Defy the laws of gravity. A simple activity has learners create a siphon pump for water. The challenge is to get water to flow upwards through a tube.

Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.

Do you think the lab smells like rotten eggs? Sorry to hear about your sulfering. A set of five experiments covers many different topics including seasons, gravity, food, precipitation, and photosynthesis. Though not presented as a...

Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...

It's a bird, it's a ... device made to mimic birds. The eighth installment of a nine-part module has pupils read various articles to learn about bird flight. They consider the implications for aeronautical engineering.

Why do you weigh more in space? Each individual in your class explores this question and others as they determine the mass and weight of different objects using two types of scales. They perform conversions and discuss their...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

Can't build a cantilever? You'll be able to after a hands-on, constructive activity. Young engineers build cantilevers out of straws and tape. The finished products must be able to hang off a table as far as possible.

Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Has your class wondered how fast a human could run or how high they are capable of jumping? Help them understand these concepts as they explore acceleration and use an accelerometer to make semiquantitative measurements of acceleration...

Balloons aren't just for parties! An inquiry-based lesson explores the idea of using balloons for space exploration. Learners become engineers as they attempt to control the ascent and descent of a helium balloon using different masses.

Create egg drop soup. Teachers first set up eggs that are held up above cups of water with a piece of cardboard and cardboard tubes. Learners try to determine a way to get the eggs to drop into the cups. Using a broom, the instructor...
