Blast Off!
Source Institutions
Students design and create their own air-powered rockets, in this hands-on activity.
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.
From Here to There
Source Institutions
In this water activity, learners discover ways to move water across the water table.
Big and Little Cups
Source Institutions
In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.
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.
Toy Chemistry
Source Institutions
In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
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.
Float or Sink?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Roving on the Moon
Add to list DetailsIn this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.
Hidden Alarm
Source Institutions
In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.
Tempest in a Teacup
Source Institutions
In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.
What's the Buzz?
Source Institutions
In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.
Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
Hang Time
Source Institutions
Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.
Kaleid-o-mania
Source Institutions
In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.
Thrill Ride
Source Institutions
In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.
Blow It Away
Source Institutions
In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.
Feel the Heat
Source Institutions
In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.
