Students explore earthquakes and seismic waves. They investigate how energy is released in the subsurface to create seismic waves. Students explore the inner workings of a seismograph and how they are used to determine the location of an...

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...

Fourth graders write poems that use local wildlife as their inspiration. After a class discussion which produces a list of wildlife that pupils have seen in their town, a review of three types of poetry ensues. They look at how...

Don't be fooled by the title; this is not really a lesson on elements. It is a project on classification, using the periodic table as an example. For that reason, it could be used in any branch of science. As an example, a group may...

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...

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...

Students 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...

Middle school environmentalists record the pH of four different liquids, including two aerosol cleaning products. They liken the products to acid rain and speculate in writing which might affect the human respiratory system. Although...

Analyzing historical legends is a fun way to develop critical-thinking skills. Pupils will use a graphic organizer to compare and contrast two historical legends relating to volcanoes. While this lesson focuses on the image of Crater...

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 examine global issues centered around HIV and AIDS. In this health science instructional activity, students compare and analyze public health measures and factors that affect the treatment of HIV/AIDS. They examine the role of...

A map of the Hudson River Valley is exhibited here. Arrows representing glacial striations are spread across the map for learners to analyze. They answer five multiple choice questions in response. The learning exercise is a compact...

It's a shame that there are no photographs in this presentation because the information is fascinating! Each identically fashioned slide contains bullet points of information about Antarctica that will enhance an earth science...

Students create cards for a memory game by entering data into a spreadsheet that is then merged into a word processing document. Tutorials are available through links on the lesson page.

Learners describe and interpret images. They make a simple sketch of an outcrop shown in a slide (or computer projection) then discuss possible interpretations.

In this science worksheet, students find the answers to the ten questions that relate common household items to having types of minerals in them.

Students classify different types of rocks. For this earth science lesson, students test different rock samples and construct a chart to record observations. They create a concept map that answers essential questions.

Students identify the three layers of the earth: core, mantle and crust. They demonstrate knowledge of the concepts of convergent and divergent motions of the earth and an understanding of plate tectonics.

Eighth graders research the connection between the convection currents within the mantle of the earth and the moving of Earth's plates. A connection to lessons at previous grade levels on the rock cycle and important background...

Students test and identify minerals according to their physical properties. In this mineral analysis instructional activity, students brainstorm ways to identify rocks and list their ideas on chart paper. Students study samples in pairs...

In this weathering and wind worksheet, students simulate the effects of weathering by wind using 2 canisters, 2 types of sandpaper and 2 sugar cubes. Students swirl the sugar cubes inside the canisters lined with fine and course...

In this changing crust worksheet, students use candy bars, licorice sticks and bubble gum to simulate the 3 types of forces that change the Earth's crust. These include compressional forces, tensional forces and transversal forces. The...

In this minerals worksheet, students read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...

Students become aware of the environmental problems caused by acid rain and study the pH scale. They determine acidity of local rain water.
