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

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners discover that a material can act differently when it's nanometer-sized.

In this activity, learners make self-assembled polymer spheres.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this game (on pages 14-21), learners explore how each human being inherits genetic traits such as eye color.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this activity, learners examine nanoscale structures of common things.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

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 investigate how some butterfly wings get their color.

In this activity, learners investigate the properties of graphene and graphite.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

In this Spanish-language chemistry activity, learners use simple materials to explore how fire extinguishers work to put out fires.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.
