Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

Engage the class like never before as pupils learn to differentiate between multiple physical and chemical changes by conducting a list of small experiments, most often with household materials. They make observations and discuss the...

Generate entertainment by assisting students in creating multiple chemical changes during the course of small experiments integrated into one packed lesson. Individuals observe examples of chemical changes as they occur and gather data...

A combination of lab activities, class discussion, and teacher demonstration shows chemistry aces the difference between physical and chemical changes. Participants track the mass of a candle as it burns, rotate through a series of...

When your upper elementary or middle school class is learning about chemical changes, these activities help demonstrate the concepts. In Part A, they submerge and place a nail partially underwater, then after a week they make...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass concretely. 

After viewing a short video about property changes, preteen scientists watch you combine different materials, and then perform two of their own experiments. For each demonstration or activity, they are to determine whether a physical or...

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. 

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...
