Come Shine with Us: Floor Polish Testing and Industrial Science To Teach Critical Thinking

Explore the unique characteristics of polymers. A complete activity begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

With Earth Day quickly approaching, as well as many science fairs, why not challenge your class to investigate geothermal energy or other renewable energy resources? There are five driving questions explored in depth here, as well as...

Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water. 

One of the factors that automotive engineers must consider is wind drag. The less wind drag, the more efficient the car will be. They perform many tests in wind tunnels, then refine their designs and test again. Using simple materials,...

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Get an up-close-and personal look at the sun from the safety of your classroom with this fun science application. Offering numerous activities, images, and videos, the resource supports children of all ages as they learn about the sun.

Spangler leads an 11 year old scientist through the processes behind his science fair project, which was designed to see if any common household liquids (besides water) would expand when frozen. Liquids such as motor oil, ethanol,...

Students prepare a test solution whose color changes when an acid or a base is added. They determine whether various household substances are acids or bases and look for patterns in the results. Students determine how their test solution...

Under the sea, the geography is as varied as it is on land! Young oceanographers find out about continental shelves, abyssal plains, seamounts, trenches, and mid-ocean ridges by viewing and reading the eight high-quality slides. Then...

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...
