Fifth graders gain knowledge about Mars and Earth. In this compare and contrast lesson, 5th graders use visual representations of the solar system to observe the characteristics of the planets. Students read fiction and nonfiction...

Students investigate the products agriculture provides in raw materials. In this agriculture products lesson, students make a list of common items used and foods eaten. Students work in teams to categorize agriculture products based...

In this ohmmeter learning exercise, students are given ten questions about circuits and and the resistance in those circuits. They explain how an ohmmeter is used and answer questions about different wire systems and their resistance.

For this electronics worksheet, students design and build a four-channel audio mixer. They complete 2 short answer questions about it.

Students analyze satellite images.  In this astronomy lesson, students examine 3 satellite images in order to understand how satellite images are taken and what they can teach scientists.

Students discuss what they know about coral reefs and are introduced to the importance of preserving coral reefs. In this coral reef lesson, students make connections between coral ecology in the classroom and in the real environment...

Sixth graders plot the a day's movement of the sun across the sky using sun dials fashioned out of clear plastic bowls. They repeat the activity at various times throughout the year and record and compare their results.

Students analyze an engineering problem. They contrast paper and pencil mastery of concepts with hands-on mastery. They present their design and rationale behind it, whether it works or not.

Students explore the light spectrum. The teacher uses holographic diffraction grafting film on an overhead to demonstrate the true nature of color. After observing a vivid rainbow, students recognize that white light is composed of all...

High schoolers investigate genetics and evolution of species. They simulate the breeding of birds using origami birds. In addition, using dice they introduce genetic variation into the species.

High schoolers investigate how Hardy-Weinberg Equilibrium is established and what assumptions and conditions are necessary to reach Equilibrium. They model alleles using materials such as index cards, M & M's and goldfish.

Place learners into groups to research and present different renewable energy sources. As individuals listen to the class presentations, they take notes and then write a persuasive article defending the form of energy that they feel...

Learners derive the equation of Gauss's law. In this physics activity, students investigate the factors affecting the strength of the electric field. They perform simulation on Gauss's law.

Young scholars investigate the concept of half-life by conducting an M&M experiment. In this chemistry activity, students differentiate nuclear fusion and fission. They present investigation findings to class.

In this comparison of evolution worksheets, students read information about Lamarck's hypothesis of evolution and Darwin's hypothesis of evolution. Students then rate the scenarios given as either supportive of Lamarck's or Darwin's...

Students, in groups, study cheetah, blind cave organisms, and naked mole rats to explain facets of evolution.

Students research the Earth's patterns of rotation and revolution, create a chart and graph of these patterns and use them to explain the causes of night and day and summer and winter.

Students discuss and role-play the elements of natural selection. They use toothpicks to represent Stick-Worms and discover the mechanisms of change of traits in populations.

Ninth graders explore soil erosion. Through a class discussion, they examine soil conservation methods. Given a potted plant, 9th graders observe the effects of erosion when water is poured over the soil. Students brainstorm terms...

Students observe the state changes in water. In this matter lesson, students observe, measure, and describe water as it changes state. Students explore how water can change from a solid to a liquid then back again. They journal their...

Learners complete guided notes while learning about the earth's seasons.

High schoolers determine the phases of the moon. They observe experiments to formulate explanations for moon phases. Students identify waxing crescent, waning gibbous, and the causes of the phases.

Students explain how moon phases occur. They explain three ways that the night sky has been used through history. Students locate some of the constellations in the night sky. They discuss stories and myths surrounding stars.

Students gather information about gene banks. In this biology activity, students work in groups to complete an activity sheet about genetic databases and organism genomes. Lesson includes extension ideas.
