Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

Second graders identify the three phases of matter and demonstrate how a property can change states of matter. In this states of matter lesson, 2nd graders make an Ooze to discover how a solid changes into a liquid. Students...

Here is an excellent lesson plan on the water cycle and the states in which water exists. Learners identify the features of the water cycle, describe how water changes form, and look at ways that people affect the natural movement of...

Does matter really matter? Properties of matter are discussed by Sam and RJ: mass, volume, and density. They differentiate between mass and weight. They explain how to measure these properties. Make sure to teach your class about other...

Students will use water and cornstarch to make a mystery matter, and then discuss what happens when different energy is applied.

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...

The Next Generation Science Standards list matter and energy as the fifth concept. The video explains how these relate to flows, cycles, and conservation. It offers an understanding of the progression of skills from kindergarten through...
