Make and Fly a Helicopter
Source Institutions
Learners follow the template to build and fly a paper helicopter.
Big Things Come in Little Packages
Source Institutions
As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
Tie Dye Painting
Source Institutions
This is an activity exploring color and color mixing.
Wetland Filter Model
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.
Estimation Exploration
Source Institutions
In this "Sid the Science Kid" activity from Episode 103: Enough With the Seashells!, learners practice estimating numbers of objects (like shells) and then check their estimates by counting.
Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
Mechanical Grabber
Source Institutions
In this engineering activity, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.
Animal Guess Who
Source Institutions
In this game, learners take turns guessing toy animals from around their house based on the toy's characteristics.
Current Events
Source Institutions
Learners model the ocean currents that carry hot water from the tropics to northern latitudes.
Topographic Investigation: Map an Underwater Surface
Source Institutions
In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.
Electroscope
Source Institutions
In this activity, learners make an electroscope out of a foam cup, straw, aluminum pie pan, thread, and foil. Learners use their electroscopes to test for static electricity.
Phenakistascope
Source Institutions
In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.
If Hot Air Rises, Why is it Cold in the Mountains?
Source Institutions
This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside
Testing Antimicrobials:: Antibacterial Soap? Do They All Work the Same?
Source Institutions
Many common household cleaners are antimicrobials.
Life in the Sidewalk Cracks
Source Institutions
In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.
Forward-Reverse Switch
Source Institutions
In this activity, learners build a switch to turn electrical circuits on and off.
Drawing Board
Source Institutions
The Drawing Board consists of a marking pen that remains stationary and a platform that swings beneath the pen, acting as a pendulum.
Roller Coasters
Source Institutions
In this activity learners will build roller coasters and test them using small balls or marbles.
Our Place in Our Galaxy
Source Institutions
In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.
The Decayed Pumpkin
Source Institutions
In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi
