Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

Students investigate the art and science of pyrotechnics.  In this chemistry and computer lesson plan, students learn about the chemical basis of fire and structure of fireworks.  Students then apply their knowledge...

Learners demonstrate that setting of plaster and cement is a change, which involves a release of heat energy, use data collected experimentally to construct comparison graphs and analyze the graphs to make predictions about future...

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...

The fifth lesson in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

For this chemical bonds learning exercise, students determine how much energy is needed to break bonds. Students classify reactions as exothermic or endothermic and identify a reaction as reversible. This learning exercise has four...

In this chemistry practice worksheet, students select the correct response to the given questions. Students apply knowledge about the states of matter, finding vapor pressure and atmospheric pressure.

Students explore latent fingerprinting. They observe a supervised demonstration of the process that real-life crime scene investigators sometimes use to identify latent fingerprints. In addition, they brainstorm ways to improve the...

In this carbon dating activity, students write and illustrate a comic strip describing the entire process of C-14 dating. Then students complete 6 short answer and 2 fill in the blank questions.

In this chemical reactions worksheet, students apply the Le Chatelier's principle to determine the equilibrium shift in the reaction based on specific changes to the system. This worksheet has 2 short answer questions and 2 problems to...

Learners investigate the changes that occur at the molecular level when a liquid becomes a solid. They freeze water in baby jars and observe the changes that occur in the process.

Learners explore the process of combustion.

Eighth graders measure temperature changes and make drawings of the interactions between matter and energy. By measuring the temperature students can conclude if there are changes in levels of energy. .

Students investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

In this thermodynamics worksheet, students answer multiple choice questions about enthalpy and entropy, they calculate molar entropies and they determine equilibrium constants and free energy of reactions.

In this bioluminescence worksheet, students read about various organisms that glow on land and in the sea. They answer three critical thinking questions after reading about these chemical reactions.

Students study oxidation and define vocabulary pertinent to it.  In this oxidation lesson students make predictions and create experiments

Eighth graders explore chemical reactions and their products. They define a chemical reaction and describe the characteristics of a chemical reaction. Students classify chemical reactions.

Students investigate the concepts of conservation of mass and simple chemical reactions. Students complete lab experiments and record all observations as well as conduct experiments on their own to determine which reactions created...

Students explore how chemistry is associated with the annual celebration of America's independence. They learn what gunpowder is made of, the anatomy of a firework, how noise is made in fireworks and the safety issues.
