Chemical Magic - Think Ink - Cool Science Experiment

If you have taught the first instructional activity 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...

In this physical and chemical change worksheet, students solve 13 clues in a crossword puzzle focusing on rates of chemical reactions and changes in the state of matter.

Students are able to observe chemcial and physical changes while producing a brilliant formation of foam. They are able to experience the use of an indicator in the reaction. Students record information based on their observations.

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...

Your enthusiastic chemists will flip over this entertaining video about matter and its chemical changes! Take an in-depth look into what chemical changes are and the evidence that is observed, such as color, smell, and heat. Then,...

Poor Sam! His graham crackers have undergone a physical change, so he can't make his s'mores! Mia explains that their molecules haven't changed, therefore they are still graham crackers. The two teens then discuss clues that would...

Want to add a wow factor to your current chemical changes lesson plan? Try a microscale experiment with colorful precipitates! Partnered learners conduct 10 single displacement reactions and record their observations.

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...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

What is more important, style or substance? This video explains the difference between physical (style) changes and chemical (substance) changes. It uses many examples and various ways of determining which type of change has occurred.
