By counting differences in amino acids, biology stars examine the relationships between different primates. With information gleaned, they map out a phylogenic tree and discover common ancestry. You will need to create printable versions...

Students draw conclusions why Mesosaurus has only been found in Africa and Brazil and how its fossil remains serve as important evidence that shows where two continents were once joined together.

Students explain and interpret topographic maps.

Students use geographic information to make an outline map of Africa, then demonstrate their understanding of the physical landscape of Africa by using a variety of materials to create a physical map of Africa

Amazing science can sometimes happen right before your eyes! The class gets cozy as they watch crystals grow. They use Epsom salts, rocks, and food coloring to create crystals. They'll observe the entire process, documenting every step...

Students consider how cavers make adaptations to the cave as do bats.

Sixth graders identify and classify changes in their lives. During the second lesson students record observations of Blue Palo Verde seed pods and predict changes over time leading to further investigations.

Students examine how gas pressure causes eruptions of explosive volcanoes, and demonstrate how the build-up of gas from dissolving alka seltzer causes the lid of a film canister to blow off. They compare/contrast between the model and...

Students examine how rocks are formed, used, and how to collect them. They listen to and discuss the book, Let's Go Rock Collecting, sort rock samples, and collect rocks from home.

Students examine how rocks are composed of different minerals. They analyze rock samples, then examine cookies, sorting out the simulated mineral ingredients from the cookies and identifying the mineral ingredients.

First graders study ways in which the earth changes due to erosion and weathering in this series of lessons.

Second graders examine how igneous rocks are formed by watching a video. They create a volcano.

Students investigate how Native American containers changed over time and how the use of pottery changed their lifestyle. They create a pottery container.

Young scholars collect and look at rocks and write down information about them in science notebooks. They make comparisons and sort the rocks according to their properties, and then discuss their findings with their classmates and put...

Fifth graders examine and discuss the topography, climate, natural resources and artwork of Costa Rica. They develop a diagram of the layers of the rain forest, and design a tourist brochure or advertisement promoting Costa Rica's...

Eleventh graders compare the artistic values of Terry Evans' photography with LandSAT images and other images made for purely scientific, government and commercial purposes. They consider the artistic choices made in aerial photography.

Students use fossils found in rocks to determine the age of rock in Illinois. They use a chart to identify the fossils and then identify the periods of rock.

Underclassmen create a cone-shaped landform and then draw a contour map for it. Then they examine a quadrangle (which was easily located with an online search), and relate it to what they experienced. The accompanying worksheet is...

Junior archaeologists examine types of artifacts from the Bronze Age on the internet. In collaborative groups, they create a story about a ship from this period and then construct a model of the ocean floor after their ship has sunk....

Students examine the soil in their local area and create a soil profile. They record observations in the field and the classroom. They create their own display of the soil profile as well.

Students review the three types of rocks and the rock cycle. They participate in an experiment in which they discover the lithification process of sedimentary rocks. They record and share their observations.

On a topographic map, students identify the scale bar, north arrow, and contour interval. They then locate a hill on the map and make note of the contour lines. Students then locate other places with similar contour line patterns....

Learners compare recent and historic maps to explore landscape changes. Using photos provided, students identify prominent features on the maps. They discuss differences in landscape, human impact on watershed, and changes in natural...

Pairs of high school biologists compare amino acid differences in the beta hemoglobin of different primates. They use the information collected to construct a phylogenic tree. Follow-up discussion questions are provided. This is a...
