In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

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.
