Students demonstrate the effect of the optic disc, or "blind spot," inherent to the optic nerve entering the posterior of the eye.

Students create a scale drawing of the atmosphere and relate it to atmospheric pressure.

Students determine the amount that sea level would rise, averaged around the globe, in response to the complete melting of several ice sheets.

Students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and compare them. Demonstrate the actual shape of the Moon's orbit around the Sun. Students will understand the gravitational forces between bodies and tidal forces generated by those bodies are different, and compare the two.

In this activity, students demonstrate the effect of the optic disc, or "blind spot," inherent to the optic nerve entering the posterior of the eye.

Students understand how some substances transmit light, some absorb, some scatter and some combine more than one process.

Students investigate motion and forces by trying to solve a problem of how to move two books across a tabletop by simply pulling on a rubber band.

Students use an IR thermometer to observe how heat energy from the sun can warm materials.

Students take on the roles of crab-like predators that have variations in the shape of "claws." Students will then go hunting/scavenging for beans on grass lawns with their feeding appendages, continuing the hunt for three rounds or "generations," with extinction and reproduction occurring between generations. To study evolution by natural selection in this predator population, the class will track the frequency of each appendage type through three generations.

Students determine the volume of water stored in the snow in the Red River Basin and give some possible reasons for why the flooding of the Red River was greater and occurred later in northern North Dakota than in southern North Dakota.

Students are placed in cooperative learning groups with the goal to teach the other members of their group a sub concept of atomic structure. Within each group, students take on the following roles: atomic number expert, mass number expert, isotope expert, and nuclear atom expert.

Students observe air pressure and recognize that air has mass and takes up space.

Students use high-resolution satellite data for selecting a new and safer location for the town of Villarrica, along with its corresponding communication and evacuation routes.

Students complete several activities to better understand how wind speed and temperature contribute to wind chill.
