In this ionic bonding worksheet, students observe diagrams about ionic bonds and crystal formation. They answer 37 short answer questions about the properties of monatomic ions, polytomic ions and write correct formulas.

High schoolers explore biotechnology. In this scenario-based lesson, students take a survey on what they know about genetic engineering, view a PowerPoint, and conduct a web quest. High schoolers will then be placed in groups, and...

Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...

For this plant reproduction worksheet, learners will compare a female cone to a male cone. Then students will review the terms associated with the parts of a plant involved with reproduction. This worksheet has 18 short answer questions.

Students demonstrate their understanding of a chemical process.  In this exploratory lesson students create a clay animation that shows how a specific type of chemical bond. 

In this nouns worksheet, students identify all the nouns in a one page text about the food chain. Students circle the 80 nouns in the passage.

Eighth graders participate in various demonstrations on electricity. In this physics lesson, 8th graders explore static and current electricity. They apply concepts to real world situations.

Students conduct an experiment to determine dew point and use a formula to detemine altitude. They construct a chart and predict what altitude clouds would form, given the dew point on the ground.

Learners explore physical education by completing a quiz in class. In this engineering lesson, students identify different ways engineering has made sports safer such as stronger padding and helmets, stronger equipment and smarter...

Students investigate the properties of heat. They explore methods of temperature control and measurement. Through experimentation and activities, students design a high tech tree house. They consider electrical, solar, and natural heat...

High schoolers study photosynthesis and chemosynthesis.  In this chemosynthetic lesson students explain the processes of these and define terms. 

High schoolers create a food web of the arctic ecosystem. In this biology lesson, students explain how global warming affects this ecosystem. They explain how losing a species affects the entire community.

In this science worksheet, young scholars look at the information carefully in preparation for a formal assessment. The focus is upon defining different aspects of air masses.

Students learn the idea of drama in their own lives; and then transfer that idea to the works of others in this series of lessons. They discuss the question of identity.

Students are shown many ways in which Mono Lake water and distilled water are different. They demonstrate that the survival of common soil bacteria declines as pH increases. Students examine the behaviors, adaptations, energy transfer,...

Ninth graders perform a series of experiment to investigate heat transfer and phase changes. In this physical science lesson, 9th graders identify and calculate the different subatomic particles. They explain the importance of scientific...

Eighth graders research and present to the class information about cloud categories. They observe clouds and describe the characteristics of their cloud observations. They take a cloud identification quiz.

Fourth graders choose a simple machine and write about they way they believe it will work. Students experiment, write down procedures used and record observations. They will find a picture of the machine and add it to their report.

Pupils confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.

Students work in groups to research and prepare a report on cloud types. They present their findings to the class and take a group quiz competing for points. Students go outside and determine which type of clouds are visible on that day.

Students work together to create a simple conductivity tester. They discover the difference between conductors and insulators. They test different types of materials for their conductivity as well.

Students are introduced to the terms related to the water cycle in their native language. In groups, they describe the steps of the cycle using different materials found in their art classroom. They describe how energy helps water...

Seventh graders participate in a number of activities designed to increase their understanding of how sound is generated and how it travels.

Students explore the amount of radiation in the Earth's atmosphere. They calculate the total amount of incoming and outgoing radiation over a day and determine how "balanced" the radiative system is over a particular location.
