In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity, learners discover that some things only stand up while they are spinning.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

This lab activity has learners create a pendulum with a one-second period.

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this math lesson, learners identify, describe, and construct the five regular polyhedra.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.
