In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

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

In this activity, learners become detectives and use chemistry to investigate fingerprints.

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

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

What keeps bubbles and other things, like airplanes, floating or flying in the air?

In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.

In this activity (on pages 10-15), learners investigate starch in human diets and how plants make starch (carbohydrates) to use as their food source.

Use grape juice, baking soda, water and vinegar to make acid and base indicator paper! This activity contains a recipe and instructions for the indicator paper.

In this activity, learners explore materials through paper chromatography.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

Learners carefully look at four known household crystals.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

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