In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

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

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

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

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.

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

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

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

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.
