Flinker
Source Institutions
In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.
Mountain Rescue Mission
Source Institutions
In this math activity, learners play a game that helps reinforce learners' understanding of the coordinate system.
Conveyor Engineering
Source Institutions
In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.
Spinning Your (Color) Wheels
Source Institutions
In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.
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!
¡Truco Con Agua!
Source Institutions
En esta actividad los aprendices aprenderán un truco de magia donde la magia es la presión del aire.
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.
Just a Minute
Source Institutions
How much can you do in one minute? In this activity, learners estimate how many times a partner can complete a task (like writing their name or jumping jacks) in one minute.
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.
Odd or Even
Source Institutions
In this math activity, learners play a game and try to collect the most cards by guessing if the next number to appear will be odd or even.
Knee Jerk Reflex (Patellar Reflex)
Source Institutions
In this quick and simple activity about reflexes (third activity on the page), learners conduct a simple test to explore the knee jerk reflex, typically conducted at the doctor's office.
Telephone Talk
Source Institutions
In this math activity, learners find patterns in telephone numbers.
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.
