Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Thirsty Candle
Source Institutions
In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.
Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.
Molecules in Motion
Source Institutions
"Molecules in Motion" explores how materials behave and change in a vacuum.
Mirror, Mirror
Source Institutions
In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.
DIY Elephant Toothpaste
Source Institutions
In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.
Sink or Swim?
Source Institutions
Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.
Liquid Lava Layers
Source Institutions
In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.
Iron in Cereal: Find iron in your food!
Source Institutions
Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.
Red, White and Blue II Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.
Constellation Tubes
Source Institutions
In this activity, learners will create their very own constellation.
Release the Grease!
Source Institutions
In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.
Identify Your Fingerprints
Source Institutions
Learners roll their fingerpads in ink pads, and then press their fingerprints onto balloons. Learners inflate the balloons to produce enlarged versions of their fingerprints.
Sock It To Me
Source Institutions
In this activity, learners discover how sweating makes us feel cooler. Learners put on one damp sock and one dry sock and sit in front of a fan.
Fireworks in a Glass
Source Institutions
In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.
Static Shock!
Source Institutions
In this hands-on activity, learners explore static electricity through the use of common household products. They also explore the connection between static electricity and cold weather.
