What's the Matter? is a guided inquiry lesson on classification of matter, physical and chemical properties, and physical and chemical changes. There are two parts to this lesson: (a) concentration game for definitions and (b)...

In this interactive lesson, learn what the "physical properties" of matter are and how can they be measured and observed.

This guide focuses on everyday substances and how we can change their properties by adding heat or cold, physically manipulating them, or mixing them together.

Investigate the changing states of water as you help Steve stay alive while in the Arctic. Includes background information about changing states of matter and about the water cycle, as well as a quiz.

Students will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...

Students use a dichotomous key to sort materials into natural and man-made and sort further using the adjectives rough and smooth; this activity builds both science and language skills as students classify materials and build deeper...

Young scholars will become familiar with transparent, translucent, and opaque objects. Students predict whether items are transparent, translucent, or opaque. Finally, young scholars will show what they have learned by producing a song,...

These notes and illustrations will help you understand the concept and properties of acceleration.

Learn more about the properties of velocity, acceleration, and force vectors in this illustrated article.

This article helps students learn about Newton's laws of motion and the properties of force.

Understand and learn about the properties of space and time and the concept of relativity.
