Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
Gumdrop Dome
Source Institutions
In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.
Friction Racing
Source Institutions
In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.
See the Colors in Leaves
Source Institutions
Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.
Take It in Stride
Source Institutions
In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.
Groovy Sounds
Source Institutions
In this activity related to music and sound vibrations, learners make a phonograph or record player out of simple materials. First, learners assemble the turntable, arm, and sound cone.
Do Plants Need Sunlight?
Source Institutions
In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.
Can Car
Source Institutions
In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.
Slime
Source Institutions
Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.
Build a Roller Coaster
Source Institutions
Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.
Amphipods: More than Mud
Source Institutions
In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.
Shake a Shrub
Source Institutions
This is an activity where learners will discover what types and how many insects live in their own backyard.
How to Test The Strength of Shapes
Source Institutions
In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.
Handwashing Laboratory Activities: Fingerprint Technique
Source Institutions
In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou
Make Your Own Weather Station
Source Institutions
This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.
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!
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.
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.
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.
Making Circuits
Source Institutions
In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!
