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...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...

Excite classes with a STEM project-based learning lesson covering chemical reactions. Groups study the different types through simulations and hands-on activities. They pick one type (synthesis, decomposition, single displacement, double...

Build a bridge to learning in a STEM-aligned unit about urban infrastructure. Young engineers explore the many aspects of civil planning and design in a five-day unit. Content includes the challenging aspects of balancing building with...

Learners explore the emotional and nutritional needs of teenagers in a six-lesson unit, which covers such topics as food sources, cooking skills, emotional well-being, and the positive effect of food and family occasions. 

Students will learn about reversible and irreversible changes in materials in this lesson.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students identify the chemical properties of a substance and describe chemical changes and differentiate them from physical changes....

Explore the differences between chemical and physical changes, including some examples at the atomic level.

Join Leander in his chemistry lesson, and learn about the change of different types of substances.

In this lesson, students match a substance with its state of matter, identify what state something is, and learn about temporary and permanent changes in matter.

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...

[Free Registration/Login may be required to access all resource tools.] Students will describe methods for separating mixtures, such as chromatography, distillation, fractional distillation, evaporation, and filtration. They will also...

Matter changes both physically and chemically on a fairly regular basis. Through these activities students will challenge their understanding of the changes that may take place with different types of matter.

Join Jacob on the Nova Zembla Expedition, and help him use suitable materials for building his house.

Do you know the difference between a physical and a chemical change? This interactive tutorial will explore these concepts!

[Free Registration/Login may be required to access all resource tools.] Definition of chemical change and examples, signs of chemical change and how it can be reversed.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

Students learn about solids, liquids, and gases in this interactive slide show. Animated cartoon characters explain concepts having to do with properties of matter. A self-checking quiz follows the lesson.
