In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

Learners and their families celebrate and recognize the importance of making healthy choices every day by participating in a health fair.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this math lesson, learners rotate through various centers while comparing and ordering objects according to length.

In this activity, learners build small animated toys that move.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

Build your own version of the classic physics toy using simple materials.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

In this activity, learners explore watercraft engineering and sailing.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
