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...

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...

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and...

What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...

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...

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...

Polymers are an important part of our day-to-day lives, but how much do your pupils know about them? Learn the basics and beyond in a series of activities designed to build skills in observation, planning, organic chemistry, and bonding.

Some reactions absorb heat while others release it. Young scholars investigate both types of reactions in a 12-lesson unit. Each lesson presents a lab investigation that monitors temperature and considers the types of reactions taking...

Add a splash of color to your chemistry class! Science scholars discover the principles behind color through a wide variety of hands-on activities. Lessons include dyes, chromatography, and flame tests.

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. 

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...

Some scientists argue that air pollution now causes more deaths than smoking. The second unit in a six-part series focuses on air quality. Scholars learn what's in the air, how clean the air around their school is, and what they can do...

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...

Mother Nature's Gravel Company is open for business! The unit includes four lessons covering weathering and erosion. Experiments are simple to complete and young geologists compare notes to see who makes the biggest ice...

Do you want to learn about how you learn? Help pupils become the best learners they can be by teaching them how their brain works. The resources available include videos about brain structure and a study guide full of activities that...

[Free Registration/Login may be required to access all resource tools.] Provides the definitions of physical and chemical changes in matter and gives examples. The law of conservation of mass is also described.

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...

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

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.] 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.
