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.
Strengthen a Paper Bridge
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp
My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
Foam Tower
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star
Heart and Lungs
Source Institutions
In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.
Paper Airplane Contest
Source Institutions
In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.
Cooling the Mummy's Tomb
Source Institutions
In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.
Build a Borneo Glider
Source Institutions
In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So
Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.
Our Sense of Sight: How We Perceive Movement, Depth and Illusions
Source Institutions
In this activity, learners investigate visual perception as well as plan and conduct their own experiments.
Building a Magic Carpet
Source Institutions
In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.
Gross Growth
Source Institutions
In this activity, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.
Trees: Recorders of Climate Change
Source Institutions
In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho
Signs of Change: Studying Tree Rings
Source Institutions
In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible
Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about
Sleep Patterns
Source Institutions
In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.
Fill 'er Up!
Source Institutions
Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.
