An acid/base indicator that's made of blended red cabbage and water is used to demonstrate the various reactions that an acid/base solution goes through when some carbon dioxide gas is added. The best way to add the carbon dioxide is to...

The best part of equilibrium is that nothing changes. A video offers a simple definition of acids and bases, common acids and bases, and their conjugates. 

Learners, through watching a simulation, can manipulate various characteristics of different solutions focusing on acid-base solutions where pH, strength of solution, and concentration may be changed. Views may be at the molecular...

Students explore light and color, including how colors are mixed to produce new colors, how light is filtered, and how light is reflected off of surfaces. They read materials provided, complete worksheets, and complete hands-on activities.

Photocopy single-color images onto acetate transparencies and either demonstrate or have your class experience the combination of colors to produce images. Children will learn that cyan, magenta, yellow, and black combine to make all of...
