Gettysburg Rocks Recycle to Win
Eighth graders use a geologic cross section to study the rock cycle of the Gettysburg battlefield. In this rock cycle activity, 8th graders connect the rock cycle and continental rifting.
Curated OER
Revolving Shapes Around an Axis
Students design a wheel that could be used on a CO2 car. In this engineering instructional activity, students investigate cylinders and volume as they perform rotation around an axis. They create patterns using circular turns about an axis.
Curated OER
Visualizing Solids of Revolution - Washers
Students solve the area of a cross section. In this calculus lesson plan, students solve areas rotated and bounded by two functions. They solve using the washer method.

It Creeps. It Crawls. Watch Out For The Blob!
How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

Modeling Riverbeds with Polynomials (part 2)
Examine the power of technology while modeling with polynomial functions. Using the website wolfram alpha, learners develop a polynomial function to model the shape of a riverbed. Ultimately, they determine the flow rate through the river.

Sketching Cones
Students sketch cones and identify its properties. In this geometry lesson, students calculate the surface area and volume of each three dimensional shape. they define and sketch prisms, pyramids and cylinders.
Curated OER
Watersheds:Stream Channels And Post-fire Stream Flows
Students draw cross sections of a stream channel from field data. In the field, using a GPS, they determine the depth of a stream channel and use a spreadsheet to graph the stream channel.

Tree Cookies
Students identify heartwood, sapwood, and a tree's annual rings, infer from a tree's rings what damage or stress might have occurred in its life, and make a time-line of human history that coincides with a tree's rings.
Curated OER
Oil Search
Students participate in a mock oil search game and attempt to find "oil" in a model oil field. They drill initially based on random guessing, but each time they drill they use prior knowledge to determine where to drill next. They must...
