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

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 complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

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

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

Using indirect methods, learners determine the shape and size of a piece of carpet hidden under a piece of plywood.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.

In this activity, learners investigate how geometry plays a role in perspective.

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

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.

In this activity, learners will explore how the human brain interprets environmental stimuli.

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

In this activity, learners make scale models of the Sun and Earth out of paper mache.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
