From the highest high to the lowest low here's a resource that won't fall flat. Given data on the area and the highest and lowest elevations of each of the 50 states, learners decide which states are the least flat and the most flat. Of...

Students make their own tooth impressions of a sharp and a flat tooth and compare the differences. They make impression of fossil teeth from dinosaurs comparing the sharp and flat teeth and learning about their uses.

Students analyze and discuss footprints and dinosaur tracks. They listen to books about paleontologists, create and analyze their own trackways using black paper and chalk, examine the data, and form hypotheses about footprints and...

Young scholars examine and simulate how paleontologists map objects. They hide and find objects using a grid to map the objects' placements.

Students create and draw fictional dinosaurs. They write a description of their dinosaur.

Learners discuss the structures of a bone and observe a demonstration of bony materials.

Students use M&Ms to simulate radioactive decay of elements.

Students make a mold using Plaster of Paris and then make a cast using that same mold. They pick a fossil and describe how it looks. They write a fictionalized story about its life, or burial. (

Learners develop abilities necessary to do scientific inquiry. They develop an understanding of chemical reactions, structures and properties of matter. They develop decision-making skills in natural and human-induced hazards.

Students participate in an archaeological excavation to determine how archeologists make inferences about various cultures. They reconstruct the site using layers of drawings. They discuss the kinds of information they learned.

Students examine physical change with different temperature and solvents. In this elements and compounds lesson, students conduct experiments to discover what happens to the mass of a substance when is undergoes a physical change.

Students visit the Hydrology Study Site, conduct a visual survey to discover info about local land use and water quality, and document their findings by mapping the water body. They use this investigation to raise questions for further...

Students follow the appropriate sampling protocol and take two measurements of a local water source. These measurements are Transparency and Temperature. This info about local land use and/or water chemistry issues may require further...

In this early primate worksheet, students will read information about the fossil evidence of the earliest primates. Students will complete 3 short answer questions based on their reading.

In this Earth's history activity, students will complete 5 true or false questions based on the early history of the Earth. Students will match 7 fossil vocabulary words to their definitions. Students will complete 4 short answer...

Students practice dating fossils. They learn the concept of "deep time"--that earth was formed billions of years ago. They experience excellent hand-outs and virtual age tutorial links.

Young scholars acquire a general knowledge of fossils and paleontology, the study of evidence of life in the past and identify the major invertebrate groups (phyla) commonly found in the fossil record.

Learners identify geographical features of different regions encountered by migrants on the Oregon trail. Students research how the Oregon landscape may have affected life and 19th century westward migration. Learners write a narrative...

Students research the evidence for prehistorically formed methane hydrates contributing to global warming. For this climate change lesson, students work in groups to research methane hydrates, global warming, The Cambrian Explosion, and...

Students examine trees and discuss how the environment effected the tree. They also predict what the area look like in fifty years.

Students explore Iowa geography and topographic maps. In this geography and topographic maps instructional activity, student investigate maps, newspapers, Iowa flora and fauna. Students gain an understanding of how different landforms...

Students use cabbage, backing soda, cobblestones, and more to test the acid in the water. In this acid mine damage lesson plan, students complete 13 experiments to test and treat acid.

Sixth graders follow in the footsteps of early scientists as they put the pieces of Pangaea back together and discovered the forces that create the variety of landforms and sea-floor features of our Earth.

In this sedimentation worksheet, students use the current rate of sediment deposit by the Colorado River in the Grand Canyon to answer questions about the changes taking place in the canyon. They graph the amount of deposit over 75 years...
