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...

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...

Now you see it, now you don't. Our moon seems to pull a disappearing act from time to time—but why? Take your seventh grade scientists above and beyond to discover the truth about the moon and the role it plays in Earth's little...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Even though they may not be tested on standardized assessments, social skills are vital for students to develop during their years in school. Through a series of discussions, activities, and role-playing exercises,...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Astronomy is literally over your head, but this lesson will explain how we study it. Young scientists make telescopes, calculate and compare the light gathering power of lenses, and simulate detection of infared radiation....

Students explore human growth and development as they participate in class activities, reading and discussion. Worksheet and handouts are included in the lesson.

This lesson focuses on the states of matter: solids, liquids, and gases. It also discusses the Kinetic Theory of Matter, Thermodynamics, Triple point, Phase Change Graphs and the Heating Curve of Water. It provideds adrawing of a heating...
