Two lessons explore the connection between energy transformation and a given job. In lesson one, small groups role-play a scenario that showcases the energy transformations that may take place during a job-specific task. The second...

Here's a resource ideal for independent learners who need extra reinforcement or would like to work ahead. These textbook chapters and practice problems cover many basic physics concepts, starting with potential and kinetic energy and...

After nine lessons and activities about energy, here is the final assessment. The 20-questions include multiple choice, multiple choice with justification, short answer, answer analysis, and labeling diagrams to challenge learners.

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Communicate chemistry clearly with a concise guide to writing chemical equations. It covers everything from the parts of a chemical equation to the different types of reactions that budding chemists may encounter.

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.

Through informational text, interactive practice problems, video clips, and real-world application, students are introduced to the science of Stoichiometry.

[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.

Resource investigates the beliefs of Dalton's atomic theory which consists of four parts. Which points do we still use today, and what have we learned since Dalton?

[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...

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

This lab experiment shows students that mass is not gained or lost during a chemical reaction. Lab also includes a set of lab questions that requires students to balance the chemical equation for the reaction that occurs in this lab.

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

Young scholars investigate whether or not chewing gum should be considered eating using the law of conservation of mass to reason that the portion lost of the original mass of gum must be swallowed.

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

Learn how mass is conserved in physical and chemical changes.

[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.
