Magnet Races
Source Institutions
In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.
Build a Rocket - and a Launch Pad!
Source Institutions
In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.
Air, It's Really There
Source Institutions
This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.
Over the Hill
Source Institutions
In this physics activity, learners construct a small-scale version of a classic carnival game.
Building Bridges
Source Institutions
In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.
Changing Colors
Source Institutions
Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.
Crater Maker
In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.
Corner Reflector
Source Institutions
In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.
Camera Projector
Source Institutions
In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
Make Your Own Paper
Source Institutions
The Chinese invented paper made from plants and cloth about 2,000 years ago. Learners follow a similar process to make paper from recycled paper.
Marshmallow Catapult
Source Institutions
In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.
Reducing Friction-Build a Hovercraft
Source Institutions
In this activity, learners learn about friction by making their own miniature hovercraft.
Why Does the Moon Have Phases?
Source Institutions
In this activity, learners use a simple 3D model to discover why the Moon has phases.
Lighting Up Celery Stalks
Source Institutions
In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla
Pom Pom Potential
Source Institutions
In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.
Self-Portrait Silhouettes: Activity 2
Source Institutions
In this activity, learners make a photographic image—without a camera!
The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
Exploring Size: Scented Balloons
Source Institutions
In this activity, learners use their sense of smell to explore the world on the nanoscale.
Bones
Source Institutions
In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.
