Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

This demonstration activity models how Venus appears from Earth.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

Learners observe the outside and inside of raw chicken eggs, record descriptions, and hypothesize what will happen when a facilitator drops an egg on the floor.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.

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 explore the relative size of the Sun and Earth as well as the distance between them.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this physics activity, learners will investigate the strength of egg shells.

In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

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

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