Pedal Power
Source Institutions
In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
ZOOM Glue
Source Institutions
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
Starting Your Container Garden
Source Institutions
This guide outlines how to plant a garden even if you don't have a yard!
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
Action Figure
Source Institutions
In this project, students explore how levers work, by making a puppet with moving limbs.
Pocket Protractor
Source Institutions
In this activity, learners create angle-measuring devices--protractors--out of paper. Learners follow a series of steps to fold a square sheet of paper into a triangular Pocket Protractor.
Zipline
Source Institutions
In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.
Print Hints
Source Institutions
In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.
Carbon Cycle Roleplay
Source Institutions
In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.
Hunger Signals
Source Institutions
This game explores the different reasons we choose to eat, and helps us be aware of when our body needs food and when it does not.
Thaumatrope
Source Institutions
In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.
Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
Plants Count
Source Institutions
In this activity, learners put on their naturalist hats and explore the world around them.
