In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners will work together to create a program to navigate a Remotely Operated Vehicle (ROV) through an obstacle course.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.
