The Shadow Knows II
Source Institutions
In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.
A Degrading Experience
Source Institutions
In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.
Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.
Blazing the Trail
Source Institutions
In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.
Rocket Pinwheel
Source Institutions
This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.
Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.
Pot-in-Pot Refrigeration
Source Institutions
In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.
Is It Possible: Estimating Measurement
Source Institutions
In this activity, learners will decide together on a question about how far, long or high the group could reach together.
Straws and Airplanes
Source Institutions
Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.
Handheld Water Bottle Rocket & Launcher
Source Institutions
In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.
Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
Solving Playground Network Problems
Source Institutions
In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.
Observing the Moon
Source Institutions
Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.
More Bubbles!
Source Institutions
In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.
For Your Eyes Only
Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.
Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.
Mountain Man Measurement Rendezvous
Source Institutions
In this math lesson, learners participate in several activities where they apply measurement skills.
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.
