Benham’s Disk
Source Institutions
In this activity (on page 2 of the PDF under GPS: Light and Color Activity), learners will see the illusion of colors produced by a rotating black and white image known as Benham’s Disk.

Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.

Probability: Rock Around The Clock
Source Institutions
In this math lesson, learners apply the Monte Carlo method of simulation to determine a reasonable estimate.

Single Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

Challenge: Microgravity
Source Institutions
In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

Water: A Basic Ingredient
Source Institutions
In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

Stained Glass Glue
Source Institutions
In this activity on page 6 of the PDF, learners use glue instead of glass to create artwork that can be hung in a window.

Marble Challenge
Source Institutions
In this physics activity (page 6 of the PDF), learners will try to keep a marble in a bottomless cup without touching the marble inside.

Hoopster: An Airplane Made from Paper Hoops
Source Institutions
This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

Iodine Investigators!
Source Institutions
In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

Exploration Vehicles
Source Institutions
Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

Exploring A Hydrogel
Source Institutions
In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

Build a Bridge
Source Institutions
In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.

Exploring Tools: Mitten Challenge
Source Institutions
In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

Torsion Drum
Source Institutions
In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

Hydraulic Car
Source Institutions
In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

Kimchee Fermentation Chamber
Source Institutions
Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.

Density Stackers
Source Institutions
In this activity, learners investigate density as they discover how liquids separate to form density layers. Learners discover what happens when they add syrup, cooking oil, and water to a jar.

The Ups and Downs of Thermometers
Source Institutions
In this activity, learners examine the parts of a thermometer. After placing a thermometer in hot and cold water, learners look at molecular model animations of the liquid in a thermometer.
