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...

Third graders study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Quiz the class on what they know before you teach it. This assessment will give you an idea of what basic scientific concepts are known to your learners. Physical change, state of matter, and basic plant and animal needs are covered.

Looking for a terrific chemistry lesson for your 5th graders? This one could be for you! After a teacher-led demonstration, learners are broken up into groups and perform an experiment using cabbage juice, water, window cleaner, and...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

The three states of matter are the focus of this chemistry video. Sal uses the example of a water molecule and explains in great detail the forces present that allow the molecule to change between a liquid, a solid, and a gas. Of course,...

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...

Sixth graders explore physical and chemical changes. In this physical science lesson, 6th graders study vocabulary, discuss the changes they see in the world and look up information on chemical and physical changes. Students create...
