Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

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.

In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.

In this activity, learners examine their tongue and taste buds.

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
