Science: Avalanche!
Eighth graders examine avalanches after reading excerpts from John Muir's book, "The Yosemite." In small groups, they conduct experiments with flour, sugar, and potato flakes representing different snow consistencies. Then, 8th graders...
Curated OER
Model Storage Facility
Students design a storage facility that can withstand extreme wind loads. In this physics activity, students decide how to build their facility considering budget constraints. They evaluate their design and present it to class.
Curated OER
Geodesic Dome
Students build geodesic domes using newspaper after watching a video about the architectural concepts used in building domes. They decide which geometric shapes can be used to build the strongest building.
Curated OER
Cytoskeleton of a Cell
Students examine the cytoskeleton of a cell. They work together to build a structure with a certain number of materials. They share their "cell" with their classmates.
Curated OER
Measure Object Using English and Metric Systems
Students are able to measure various objects using English and metric systems within half of the smallest unit of the measurement device. Students identify units of length, volume, mass and temperature according to International System...

Earthquake Crossword
In this earth science worksheet, learners find the words that are related to earthquakes. The answers are found at the bottom of the page.
Curated OER
Avalanche!
Middle schoolers explain that when forces on an object are balanced, the motion of object does not change. They describe how an object changes its motion when forces on it are unbalanced. They plan and conduct a scientific investigation...
Curated OER
Daphnia and Algae: A Study of Pond Dynamics
Students observe interrelationships and interdependencies of organisms which may generate stable ecosystems. They also study that living organisms have the capacity to produce infinite sized populations, but environments and resources...
Curated OER
Design & Technology: Materials Strength
Young scholars investigate the function of a floor stretcher and some of the past designs. The goal is to improve the design durability and ease of use. Then they sketch their ideas and write a rationale for changes made to the structure.
Curated OER
Types of Forces
Students study scientific names and descriptions of forces. In this motion lesson students organize information into a graphic organizer then teach it to other students.
