Students are given maps depicting two or more air masses and they then categorize bodies of air by temperature and moisture characteristics. They recognize large regions of similar type air. Students are given a map of air temperatures...

Students discuss ways our environment becomes polluted. They make a list of ways to keep it clean.

Students examine the concepts of porosity and permeability. They conduct experiments to determine the porosity and permeability of gravel, sand, and clay. After performing the experiments they collect and graph data, comparing the...

Livestock managers reinforce math and science skills while learning about the nutrients found in manure. They predict which animal produces the largest amount and which animal's manure contains the most nitrogen. Finally, they compare...

In this reactions worksheet, students use Hess's Law to calculate the heat gained or lost by different reactions. Students determine if the reaction would occur spontaneously at a given temperature. This worksheet has 9 problems to solve.

Tenth graders observe enzyme activity. They discuss the relationship between drug use and enzyme activity.

Seventh graders study and make a model of the significant formations of the ocean floor. They examine images and illustration and apply their imagination while creating the model. They are challenged to complete further research as an...

Students explore the average surface temperature of planets. They use the Planet Temperature Calculator to find the average temperature. Students explore how the distance from the sun affects the Earth's average surface temperature. They...

Second graders study the life cycle of a butterfly by observing metamorphosis taking place in a butterfly pavilion. Students illustrate their understandings of the body parts of a caterpillar and butterfly, as well as the life cycle,...

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.

Students explore fish adaptations and anatomy. In this science lesson, students discuss various adaptations of fish and how those adaptations help them.

Sixth graders experiment with mixtures. In this chemistry activity, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

Sixth graders investigate the difference between rocks and minerals. They name the three kinds of rocks (sedimentary, igneous, and metamorphic) and know the differences between them.

Pupils use screens of three sizes to separate a mixture of five solid materials. They plan and conduct simple investigations using appropriate tools, measures, and safety rules and record and report observations, explanations, and...

Learners write a report about energy use. In this conservation lesson, students interview adults about their use of renewable and nonrenewable energy. Learners synthesize this information and write a report from the point of view of a...

Students view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.

Young scholars study how people have tried to save beaches from wave erosion. They examine what has occurred to Cape Hatteras as a result of beach erosion and the efforts to reduce the erosion.

Students create acid rain using carbonic, nitrous, nitric, and sulfurous acids.

Young scholars are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.

Students investigate human needs and how they have adapted to different environments. They complete an experiment to discover the effect of stress on muscles. They use the food pyramid to create a plan for healthy eating.
