This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

In this activity, learners explore Charles' Law in a syringe.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

This lesson focuses on how materials behave differently as their surface area increases.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.
