Number Sense and Computation: An Apple a Day
Source Institutions
In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.

Visualizing How the Vestibular System Works
Source Institutions
In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

Shoe Dichotomous Key
Source Institutions
In this activity (on page 2 of the PDF under GPS: Cactus Activity), learners will develop their own version of a tool used by biologists, a dichotomous key, by collecting all their left shoes.

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.

What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

Building Blocks
Source Institutions
In this activity (page 32 of PDF), learners investigate the nutritional needs of healthy bones and muscles.

Living Clocks
Source Institutions
In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

Try Your Hand at Nano
Source Institutions
This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

Rockets Away!
Source Institutions
In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.

Marble Drop Game
Source Institutions
Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

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.

Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

Statistics: Steppin' Out
Source Institutions
In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

Probability: Chances Are
Source Institutions
In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

Paper Drop Design Competition
Source Institutions
Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

Shark Sizes
Source Institutions
In this graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.

Wet Art
Source Institutions
In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

That's the Way the Ball Bounces: Level 1
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

Doughy Physics
Source Institutions
Learners drop two different masses of play dough and observe how long it takes them to hit the ground.
