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...

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....

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...

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,...

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

Through an instructional video, games, and activities, students explore three types of change matter makes: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form...

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

Using simulations observe what solids, liquids, and gases look like at the atomic scale. After observing the different states of matter at their atomic level, students will be able to conclude about the forces and attractions that exist...

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...

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...
