Flame Out

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

Students see evidence of chemical reaction and follow the scientific method to hypothesize, observe, and reach conclusions. They conduct a series of egg based experiments such as forming crystals and complete journal activities as a...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

By both demonstration and hands-on investigation, physical science fanatics come to know that some materials react when they come together. Adding vinegar to both baking soda and to baking powder, the difference between the two is clear....

First graders discover that a chemical reaction is responsible for the effects seen with Crayola Color Wonder markers. They observe that the color changes are the result of a chemical reaction between chemicals in the Color Wonder paper...

In this chemical and physical reactions worksheet, learners read a 2 page science article, answer 10 statements as true or false, give 2 ways a chemical reaction is different from a physical reaction, answer 1 short answer question and...

Thinking back to the last time you taught a lesson on chemical changes ... was there no reaction? Check out an explosive video to put some spark back in your instruction! The narrator of the video guides you through the expectations, as...

Get a surprised reaction from trying out the chemical reaction. Scholars conduct a chemical experiment by adding yeast to hydrogen peroxide and dish soap in a plastic bottle. They learn that yeast contains a catalase enzyme that releases...
