Pupils use a video, the Internet and hands-on activities to explore how to determine the age of rocks and fossils based on radioactive decay data.

Students study acid rain and complete several activities that show how it affects the environment. They role play members of the community involved in a major decision involving the protection of the environment.

Learners explore the causes and effects of the Earth's ozone holes through discussion and an interactive simulation. Using gumdrops and toothpicks, they conduct a large-group, interactive ozone depletion model.

Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of radiation for different surfaces. Students follow instructions in this guided inquiry based lab and are then asked...

Students define what a city is. They investigate the top 10 - 15 most populated cities. SDescribe factors influencing the location and growth of urban sites. They site examples of cities that have grown with different models of urban...

Pupils observe and demonstrate how objects can be charged positively and negatively and how static electricity works. They observe a teacher-led demonstration, and in small groups rotate through various static electricity activities,...

Students explore the origin and distribution of oil and gas in a region of global significance, the Middle East including the geologic history and the socio-political and environmental issues associated with hydrocarbon exploration and...

Fourth graders explore The Great Wall of China and use materials to make a class Great Wall of China students measure a portion of the classroom, school or playground and construct a "Great Wall" to scale.

Young scientists access the EARTH Web site in order to engage in this lesson life forms found in the ocean. Student groups of 3 - 4 choose one set of deep-sea organism images. The groups decide how they would classify their organisms and...

If you are teaching physical oceanography to middle school earth scientists, here is a terrific multiple choice worksheet. Learners look at a diagram of a landscape created by glacial sediment deposition and the resulting ocean floor....

How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...

Two hands-on activities celebrate the sun and moon autumnal equinox. First, scholars create a cairn using a shoebox, flashlight, and drawing tools to view the sun's progression. Second, learners take to the kitchen to bake mooncakes...

Students explore the Earth's movements by completing worksheets. In this plate tectonics lesson, students define such natural disasters as volcanoes, earthquakes, tsunamis and mudslides and discuss their connections to plate tectonics....

Students discuss the effects of earthquakes. In this earth science lesson, students create earthquake models and earthquake-proof buildings. They construct their own seismograph.

Students explain how melting glaciers affect global warming. In this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Students participate in a simulation of the equal and unequal distribution of the earth's renewable resources. They discuss renewable resources and how food resources can increase and decrease, participate in the simulation, and analyze...

Sixth graders explore standard and nonstandard measurement. In this measurement lesson, 6th graders estimate the lengths of different objects and write about their observations during measuring. Students work in groups to...

Second graders study Earth's materials. In this air and weather lesson, 2nd graders note changes in the weather and examine tools that help us study the weather. Students analyze how changes in the environment make changes in the...

Fourth graders explore the three layers of the Earth describing the composition, thickness, and temperature of each layer. Layers are compared and contrasted and data unearthed placed into graphic organizers.

Students investigate space travel. In this science lesson, students discuss the space station and its representation in orbit. They talk about food, travel and survival in space with the correct equipment.

Eighth graders study how and why animals are classified into eight groups in the animal kingdom. They work together to identify organisms. They use the key to determine the phylum for the included problems.

Geology beginners examine three different rock samples and determine their origin by their characteristics. By making and recording observations, they become familiar with features of igneous, metamorphic, and sedimentary rock types....

Students view cut-away images of the planets' interiors, comparing and contrasting them with the Earth's in written form. Students also classify each planet as "terrestrial" or "Jovian". The Planet Interiors applet on the CSA website...

Discover the change of the seasons by modeling the Earth-Sun system. Learners model the orbit of the Earth around the sun and explore how and why the patterns of winter and summer occur.
