Source Institutions
In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.
Your Energy Needs
Source Institutions
In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.
Building Blocks
Source Institutions
In this activity (page 32 of PDF), learners investigate the nutritional needs of healthy bones and muscles.
Double Horn
Source Institutions
In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.
Muscle Fibers
Source Institutions
In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.
Probability: Chances Are
Source Institutions
In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.
Shark Sizes
Source Institutions
In this graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.
Eyepatch Challenge
Source Institutions
In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.
Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.
Electric Gamebox Challenge
Source Institutions
In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.
On Target
Source Institutions
In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.
