Can You Make Ice Cream in Two Minutes?
Source Institutions
In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

Root Beer Float
Source Institutions
In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

Chocolate Chip Cookie Constellations
Source Institutions
This chocolate chip cookie recipe includes templates for baking night sky constellations of the season right on top! Two templates are included, one for 9pm mid-April, and one for 10pm mid-July.

Colors Collide or Combine
Source Institutions
Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

Universal Indicator Rainbow Trout
Source Institutions
In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

Mysterious M&M's
Source Institutions
Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

Color Changes with Acids and Bases
Source Institutions
Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.

Fizzy Fun
Source Institutions
In this activity, learners test what happens when they put baking power on different frozen liquids.

Build a Fruit Fly Trap
Source Institutions
In this construction activity, students use a 2-liter bottle to build a fly trap.

Avi's Sensational Salt Dough
Source Institutions
In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.

Change in Temperature: Endothermic Reaction
Source Institutions
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

Breathing Yeasties
Source Institutions
Does yeast breathe? Find out by watching how plastic bags filled with yeast, warm water and different amounts of sugar change over time.

Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

Invisible Ink
Source Institutions
In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

Chicken Wing Exploration
Source Institutions
In this activity, learners explore cooked chicken wings and identify the various parts including: bones (radius, ulna, humerus, shoulder joint, elbow joint), tendons, and cartilage.

Oily Ice
Source Institutions
In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

Mix and Match
Source Institutions
In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

M&M's in Different Temperatures
Source Institutions
Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
