In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

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 activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners will explore saturated solutions and discover how crystals form.

In this activity, learners create secret messages using a candle. Learners discover that watercolor paint is attracted to some materials, like paper fibers, but not others, like oil.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

In this activity, learners will experiment with salt and ice in order to turn a bag of ingredients into ice cream.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.

In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?

In the kitchen, learners can perform their own density investigation.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

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.

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.
