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.

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.

Make Your Own Batteries!
Source Institutions
This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

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.

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.

Baseball
Source Institutions
In this math activity (Page 17 of the Play Ball! PDF), learners play a game of "baseball" and analyze the results of the game.

Treasure Hunters
Source Institutions
Learners use their opponent's clues and a compass rose to find the hidden treasure on a map. Learners use problem solving and coordinate grid skills as they hunt for treasure.

Virtual Farm Management
Source Institutions
This activity (located on page 3 of the PDF under GPS: Farm Animals Activity) is a full inquiry investigation into raising livestock.

Traveling Nanoparticles Model
Source Institutions
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

Where Was That?
Source Institutions
In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

Our Sense of Touch: Two-Point Discrimination
Source Institutions
In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

Stairway to the Sky
Source Institutions
In this math activity, learners use cubes to calculate how many blocks it would take to build stairways with different heights.
