ZOOM Glue
Source Institutions
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

Natural Indicators
Source Institutions
Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

Spill Spread
Source Institutions
In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

Acids & Bases
Source Institutions
In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

Cabbage Juice Indicator: Test the pH of household products
Source Institutions
Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

Copper Cleanup
Source Institutions
In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

There's Always Room For JELL-O
Source Institutions
In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

Erupting Fizz
Source Institutions
This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

Finding the Carbon in Sugar
Source Institutions
In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

Save Your Skin
Source Institutions
This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

Comparing the Amount of Acid in Different Solutions
Source Institutions
In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.

Atoms and Matter (3-6)
Source Institutions
In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

Why Circulate?
Source Institutions
In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

Kool Colors
Source Institutions
Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.

Make Your Own Batteries!
Source Institutions
This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

Edible Glass
Source Institutions
In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

Plastic Milk: You can make plastic from milk
Source Institutions
In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.
