Blast Off!
Source Institutions
Students design and create their own air-powered rockets, in this hands-on activity.
Gravity in Action
Source Institutions
Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.
Where Will It Go?
Source Institutions
In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.
Rocket Launchers
Source Institutions
In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.
Cupcake Delivery
Source Institutions
In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.
The Rumblin' Road: Determining distance to a Thunderstorm
Source Institutions
In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.
Boomerang
Source Institutions
Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.
Pinball Wizard
Source Institutions
In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.
Canine House of Cards
Source Institutions
This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.
Inkjet Printer
Source Institutions
In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.
Helicopter Twirl
Source Institutions
Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.
Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.
Pop Bottle Whirligig
Source Institutions
Learn about friction and kinetic energy with this cool spinning toy.
Ramp Racers
Source Institutions
In this activity about friction and gravity (page seven of the pdf), learners use toy racing cars to explore how the two forces affect the motion of objects.
Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
3-2-1 POP!
Source Institutions
In this physics activity, learners build their own rockets out of film canisters and construction paper.
Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
