Constellation Detective
Source Institutions
In this quick activity, learners practice locating a constellation in a map of very dark skies.
Make a Water Cycle Wristband
Source Institutions
In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.
Pop Fly
Source Institutions
In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!
Make Recycled Paper
Source Institutions
Learners shred used paper, add water, and blend it into pulp. They then strain and roll the pulp out to make new paper.
Overlapping Spots: Make a bright spot brighter
Source Institutions
This perception trick focuses on conflicting information to the brain...instead of trying to see two images, you're trying to get a bright spot by overlapping the image you see through two tubes.
Why is the Sky Purple?
Source Institutions
This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
Kicking Machine
Source Institutions
In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.
Self-Assembly Game
Source Institutions
This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.
Model Well
Source Institutions
In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.
Afterimage
Source Institutions
In this optics activity, learners investigate afterimages.
Toothpick Patterns
Source Institutions
In this math activity, learners make toothpick designs by following simple patterns.
Tip Topper
Source Institutions
In this math activity, learners role-play as wait staff at the Kidtropolis Diner. It's the end of the night and it's time for the staff to collect their tips.
Achi: A Strange Game of Tic Tac Toe
Source Institutions
In this game, learners strategize to be the first player to make three in a row.
Hot Spoons
Source Institutions
In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.
An Object in Motion
Source Institutions
In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.
Subtracta's Dog
Source Institutions
In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.
Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
Snake
Source Institutions
In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.
Pupil to Pupil
Source Institutions
In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.
The Braille Alphabet
Source Institutions
In this activity (8th activity on the page) about the sense of touch, learners make their own set of Braille letters. Learners use glue to make raised dots on a Braille Alphabet Sheet.
