In this half-life worksheet, students determine how much of the radioactive isotopes will remain after a certain amount of time. This worksheet has 11 problems to solve.

Students explore volcanoes. In this science lesson plan, students discuss the characteristics of volcanoes and view a video segment about a volcano. Students examine plate tectonics.

Students observe the growth of a seed, predict what will happen when seeds are planted without soil, and conduct an experiment using a hydroponics system.

Ninth graders complete a unit of lessons on ecosystems, organism interactions, and energy flow. They create a key for known species of fish, diagram the movement of energy through an ecosystem, and create and present food chains and food...

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...

Learners investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...

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

Students investigate the magnetic attraction of different materials by observing a demonstration, and review the words "attraction" and "materials." Next they conduct exploration of a number of materials which have different properties...

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.

In this mixtures worksheet, students fill in 7 blanks, determine if 4 statements are true or false, match 7 terms with the appropriate definitions, and solve 2 problems. These include topics such as homogeneous and heterogeneous...

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

Fifth graders research energy sources used in the United States. In this energy sources lesson, 5th graders work in teams to research various energy sources. Students complete a worksheet for the research and make a short video 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.

Students examine Chinese folktales. In this literature and philanthropy instructional activity, students read Chinese folktales and analyze their literary elements. Students consider the effects of generosity in the tales and in their...

Students determine how geography affects how people live, work and play. They identify the different landforms in the three regions of Peru and create a travel brochure highlighting Peru's attractions.

Students gain an understanding of Peru's history. They analyze how specific ideas and beliefs have had an effect on a particular period of time and they trace the route of the Spanish Conquistadors on a map of Peru.

Students recognize that global winds move in specific directions in specific latitudes and describe that in a written form. They relate the motion of the wind belts to historical navigation.

Students simulate the Coriolis Effect to comprehend why winds in the Westerlies are prone to cyclonic and anti-cyclonic motion. They arrive at an explanation of processes that drive world wind patterns

Students predict the flow of an oil spill and depict it on a map. They explain the predicted route of the oil spill using knowledge of ocean currents in a short presentation to their peers.

Fifth graders examine animal adaptations and how they meet their needs in a variety of environments. They discuss how they might adapt to their own environment before discussing how an animal could adapt. Next, they complete an...

Middle schoolers examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph...

Eighth graders demonstrate how scientific principles can be used to provide resources in an emergency situation.  In this evaporation lesson students view a demonstration on a solar still and see a brief PowerPoint presentation. 

Students compare the weathering of different-sized materials. Comparisons are made and data analyzed to reach conclusions about the process of weathering. Applications can be made for the higher grades.

Second graders define condensation and evaporation. They identify and describe the steps in the water cycle. They ask questions to end the lesson.
