Senses

By Ida Murray          Grades: 3 - 4

Concept: Human and animals use their senses to survive.

Comparing Friction

By Patty Brown        Grade 5 - 6

Concept: Friction varies with type of surface

Investigating Plants of the Tongass

By Connie Tracy       Grade: 6th

Concept: Students will recognize and identify some plants from their local ecosystem, including plant signs during the non-growing seasons.

Adaptations

By Emily Roseberry       Grade: 7 - 9

Concept: Living things have special adaptations for survival

Friction

By Ben Collman       Grade: 9th

Concept: Friction is a force that opposes relative motion (sliding) between two surfaces. The size of the friction force is (nearly) independent of the surface area of contact. The size of the friction force between two surfaces is proportional to the force with which the two surfaces are pressed together. The nature of the surfaces in contact can also affect the size of the friction force.

Nitrogen Cycle

By Susan Fredrickson       Grade 9 - 10

Concept: All organisms need nitrogen to build proteins, which are used to build new cells. Plants that do not have nitrogen-fixing bacteria in their roots must get nitrogen from the soil, or die.
