Tenth graders test their saliva for enzyme activity. In this enzyme lesson, 10th graders conduct an experiment to test the enzymatic activity of their saliva. They relate the lack of certain digestive enzymes with alcoholism.

The radical reactions of polymers seems abstract to many pupils, but this lesson turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and experimental weight...

Meant to be used in connection with the article "In Teacher Ratings, Good Test Scores Are Sometimes Not Good Enough" also available on The New York Times website, this resource provides 12 short-answer writing prompts that ask both basic...

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...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

In this kinetics worksheet, students solve twenty one problems related to reaction rates, half life, reaction orders, catalysts, and activation energy.

Students determine that the rate of reaction is affected by temperature, surface area, concentration of reagent, and addition of a catalyst or inhibitor. They observe that on December 3rd, 1984, 8000 people died when the chemical plant...

Students analyze the lifetime accomplishments of Muhammad Ali in the area of sports and his role as a catalyst for social change.

Students analyze the lyrics of protest songs as a catalyst for social change. They discuss the influence of music on behavior and explain the use of music as a means of self-expression.

In this photosynthesis, disease and Immune System worksheet, students fill in the blanks with key terms to complete sentences about the transfer of energy from the sun to plants, enzymes as catalysts in reactions, homeostasis, the immune...

Eleventh graders examine the qualities of a leader.  In this American History lesson, 11th graders read the story of Nathaniel Bowditch and use it as a catalyst for discussions on leadership and the definition of a hero.  

Discover the connection between redox reactions and fuel cells. Collaborative groups build a Hoffmann Apparatus that demonstrates the electrolysis of water and then convert their models into a fuel cell. They use their fuel cells to...

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

If you've ever felt a little drained ... try converting some ATP to ADP! Science scholars perform one of life's most important reactions using a simulated lab workbench. The fun-to-use interactive allows pupils to control the reactants...

What a big job for such a small particle. Young scientists learn about the role of nanoparticles in catalytic converters for cars. They conduct an experiment to create alginate-MnO2 catalytic spheres. 

Scholars learn about kinetics and buffers as they use qualitative and quantitative methods to understand enzyme rates and buffer capacity. The application of Beer's Law and spectrophotometry solidifies pupils' knowledge in the first of...

More than 80,000 scholars earned college credit for Chemistry with the AP exam in 2015. The College Board released the free-response questions covering topics, including moles, that often confuse scholars. They also released example...

Students observe the chemical change that occurs when sodium iodide is dropped into a flask containing 30% hydrogen peroxide. They discuss how this exothermic reaction occurred as they study the chemical equation involved in the reaction.

The 1955 murder of Emmett Till is often regarded as the catalyst for the Civil Rights Movement of the 20th century. Learn more about the brutal crime—and, as many believe, the miscarriage of justice—that began a national conversation...

Students explore light, and how it travels in straight path, recognize that light-sensitive chemical processes can be used to create images using light as catalyst, discover that light can be refracted by convex lens to focus camera,...

Students explore how enzymes are important in the chemical reactions of all living things.  In this enzymes and catalysts lesson plan students complete an activity to see how enzymes change living things.

Students investigate alternative catalysts for the degradation of hydrogen peroxide.  In this fermentation lesson plan students complete an activity that breaks down cellulose into sugar. 

Students visit science museums. In this hands-on science lesson, students visit the Leith Conservation Trust, Catalyst, and the River and Rowing Museum in person or online to study Britain's waterways.

High schoolers analyze the lyrics of protest songs as a catalyst for social change. They discuss the influence of music on behavior and explain the use of music as historical record.
