In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this math lesson, learners rotate through six estimating and measuring centers. First, learners read the book, "Room for Ripley" by Stuart J.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

In this activity, learners examine the culture and history of the tomb site.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

This activity has learners observe water and compare it to other liquids.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity learners will explore the concepts of density and matter in their quest to answer one simple question-will it sink or will it float?

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

Learners play the role of materials engineers as they test the flexibility of different materials.
