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 graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.

In this story time program, young learners listen to the Dr.

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

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

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

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

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.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

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.

This activity combines learning about nutrition, math of measurement and proportion, and healthy eating. Start by distributing food packages with Nutrition Facts labeled.

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

In this activity, learners will build the highest tower they can out of recycled materials.

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.
