When your mom tells you to chew your food, you really should listen! A lesson plan on the digestive system examines the first step of digestion that happens in the mouth. Learners check crackers and use iodine to highlight changes...

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...

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.

In this physical world instructional activity, students review concepts relating to the chemical and physical properties of matter, density of matter, and if matter is a solid, liquid, or gas. This instructional activity has 9 terms in a...

Students examine different types of chemical reactions. They explore how alcohol molecules affect the reaction rates. They answer discussion questions to end the instructional activity.

Students show the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They see the flaws associated with this thinking because of the lack of CO2 and H2O and lack of sufficient gravity in order...

Students examine water. In 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...

In this matter worksheet, students answer ten questions about matter including the phase of matter, mixtures and how they are different from compounds, the physical and chemical properties of matter and the difference between homogeneous...

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...

In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...

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...

Students are introduced to the concept of chemical change when they observe the chemical change that occurs between vinegar or lemon juice and heat.

Students investigate quality of water in a stream, lake, or pond by examining chemical, physical, and biological characteristics.

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

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....

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...

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...

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....

High schoolers determine the physical and chemical factors that affect plant growth. In this biology lesson, students explain the role of hormones in plants. They investigate how competition with other plants affect their growth.

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

Students identify substances and discover common substances and their chemical composition.  In this chemistry lesson students write a description of the substances and how they are used.

In this anatomy worksheet, students complete 22 review questions in the format of short answer, table completion, and fill in the blank after finishing an online virtual experiment about the chemical and physical processes of digestion.
