Collect Invertebrates to Determine Water Quality
Source Institutions
This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.
Quipus
Source Institutions
Learners create an Incan counting device called a quipu (pronounced kee-poo).
Sink or Swim?
Source Institutions
Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.
Who Can Harvest a Walleye?
Source Institutions
This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.
Oil and Soap
Source Institutions
Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.
Bending Light
Source Institutions
In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.
Shark Cart
Source Institutions
In this activity, learners touch and observe skulls of sharks and rays to learn about their diversity (over 400 species of sharks alone!).
Binary Challenge
Source Institutions
In this activity, learners cut out 5 paper cards and label them with 1, 2, 4, 8, or 16 dot(s) to explore binary digits.
Any Year Calendars
Source Institutions
This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.

Source Institutions
This strategy game has simple rules but can be a challenge. Players start with an empty hexagonal grid. On each turn, a player initials one empty hexagon on the grid.
How the Rubber Meets the Road
Source Institutions
In this activity, learners explore how engineers design tire treads to increase safety and reliability.
Magic Sand: Nanosurfaces
Source Institutions
This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).
Freezing Lakes
Source Institutions
In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.
Crystal Stencil Stars
Source Institutions
In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.
When is a Glass of Water Really Full?
Source Institutions
In this activity, learners see how many coins they can add to a full glass of water before the water overflows.
Homemade Rube Goldberg Machine
Source Institutions
In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.
Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.
A Feast for Yeast
Source Institutions
In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.
Our Solar System to Scale
Source Institutions
In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.
Make a Mobile!
