Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Young scientists explore many different types of energy including light, heat, nuclear, sound, potential, and more. They match the types of energy and identify when energy transfers from one type to another.

Students conduct a series of experiments in which they explore chemical reactions. They detect chemical changes by observing how physical properties change when two different chemicals are combined. They list and describe the reactants...

In this chemical reactions worksheet, students fill in 12 blanks with the appropriate terms related to chemical reactions. They also indicate if 4 statements are true or false and match 7 words with their descriptions. Students complete...

Eighth graders are introduced to the topic of Environmental Chemistry. In groups, they review the steps within the scientific method and develop their own hypothesis and design an experiment. They solve equations related to the...

Pupils examine water. For this chemistry lesson, student examine the physical properties of water and how it changes from a liquid to a solid or a gas. This lesson contains links to a second and third complimentary lesson on evaporation,...

In this chemistry review instructional activity, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...

Introduce physical science learners to the forms of energy using this PowerPoint. The concluding slides present scenarios for discussing the transfer of energy from one form to another. Informative text is crisp and attractive, but the...

Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...

Middle schoolers study the chemical and physical weathering of "rocks".  In this weathering experiments lesson students complete a lab that demonstrates how rocks weather.

Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

Combine science and reading skills with a reading comprehension exercise. Kids read four paragraphs about energy conversion and answer some reading comprehension questions about the information they have read.

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

Students investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...

For this conservation of mass worksheet, students design an investigation to demonstrate the Law of Conservation of Mass. Students describe their investigation, collect data, graph the data and write a conclusion about what they discovered.

Students differentiate physical and chemical changes. For this chemistry lesson, students give examples of each type of change. They take the review quiz at the end of the lesson.

Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....

Elementary school physical scientists explore kinetic mechanical energy by dropping a golf ball on different surfaces. They discuss how human made materials might react to light differently from nature made materials. This lesson plan...

This PowerPoint progresses slide-by-slide through all the facts you would want to deliver about acids, alkalis, salts, and the related lab tests. Each slide has one or two facts about a physical or chemical property or behavior. The...
