Sea Turtle First Aid Investigation
Source Institutions
This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

Can Nutrients in Water Cause Harm?
Source Institutions
In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

Racing with the Sun: Creating a Solar Car
Source Institutions
Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

Hot Stuff!: Creating and Testing for Carbon Dioxide
In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

How to Make an Audio Tape Bow
Source Institutions
From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.

Family Fort Challenge
Source Institutions
In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

Sugar Crystal Challenge
Source Institutions
This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

Bright Lights
Source Institutions
In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

What is a Nanometer?
Source Institutions
This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

The Self-Watering Terrarium
Source Institutions
In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

Home Water Audit
Source Institutions
This activity offers learners and their families several ways to raise their awareness together about home water.

Balls and Ramps
Source Institutions
In this activity, learners use simple, everyday materials to experiment with balls and ramps.

Marshmallow Models
Source Institutions
No glue is needed for learners of any age to become marshmallow architects or engineers.

Divide and Conquer
Source Institutions
Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

Hot Stuff!: Testing Ice
In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

Build A Bee Bath
Source Institutions
In this activity, learners use found natural materials to create a water haven for bees and other insects.

Hot Cans and Cold Cans
Source Institutions
Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

Airplane Wing Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

Shrinking Cups
Source Institutions
This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.
