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...

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....

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...

Designed to use when teaching adults preparing for their high school equivalency exam, the resource integrates reading practice, writing, and analytical thinking in every lesson. The unit covers 23 topics, but it only includes three...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

How important is water quality where you live? The first module in a six-unit series includes four lessons on water quality. By applying the concept directly to the lives of pupils, they engage in meaningful learning. They read about...

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...

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

The first STEM lesson in a group of 10 explores composting. After discussing how to make a better tomorrow, classes are challenged to track garbage in their communities, visit a local waste management facility, and conduct a survey...

Many muralists throughout history have focused on using their art to represent aspects of their culture or community. After thoroughly researching several muralists, budding artists will create a larger than life mural that contains...

Students explore energy usage in home and in school. They examine the types of non-renewable sources and discover alternate sources of energy. Through group activities, students calculate the perimeter and area of a given room. They make...

[Free Registration/Login may be required to access all resource tools.] The law of conservation of mass and an example.

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.

Everything in our universe has mass- from the smallest atom to the largest star. But the amount of mass has remained constant throughout existence even during the birth and death of stars, planets and you. How can the universe grow while...

This resource includes videos, interactives, and additional resources to help students understand the law of conservation of mass and how to balance chemical equations.

Learn about the conservation of mass and energy as it applies to different living systems.

[Free Registration/Login may be required to access all resource tools.] Explains Law of conservation of mass and why chemical equations must be balanced.

This lesson explains the law of conservation of mass within chemical reaction with audio and quiz questions.

[Free Registration/Login may be required to access all resource tools.] In this module, students will learn about the cycles of nature (water, carbon, nitrogen, and phosphorus) that support the flow of nutrient matter through an...

Atoms and molecules come together to create matter. What happens to the weight of matter when it is frozen? Can matter be destroyed? Check out these activities to clearly understand how this works.

Explore balanced chemical equations in this tutorial. Tutorial includes videos, interactive activities, and practice to help students understand balanced chemical equations and the Law of Conservation of Mass.

Learn how mass is conserved in physical and chemical changes.

[Free Registration/Login may be required to access all resource tools.] What happens in a chemical reaction is explained, along with how it is represented by a chemical equation. In a chemical reaction, the law of conservation of matter...

[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.
