In this activity, learners investigate passive solar building design with a focus solely on heating.

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity about cartography, learners work in teams to create two different map projections: a planar (or polar) and a cylindrical (or Mercator) projection.

In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

In this activity, learners make their own encrypted code to pass along secret messages using a printable cipher wheel.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.
