Homeostasis, Negative Feedback, and Positive Feedback
So many bodily activities depend on homeostasis! Give learners a solid background to understand the basic process of the human body. Scholars first examine negative feedback loops contributing to body temperature regulation and then a...

End of Unit Assessment, Part 1, Continued: Revising Vocabulary and Conventions Based on Feedback
Writers align their position papers with the last two rows in the rubric. After looking at the rubric rows for vocabulary and conventions along with feedback on their papers, class members revise their essays. They then look at the...

Homeostasis and Negative Feedback – Concepts and Breathing Experiments
More asthma attacks happen at higher altitudes, but why? Scholars complete worksheets, learning about homeostasis and feedback related to breathing. Then, they work in small groups to experiment with breathing in limited amounts of...

Permafrost Thaw Depth and Ground Cover
The thaw depth of tundra creates a positive feedback loop with both global warming and the carbon cycle. Scholars sort photos and develop a hypothesis for ground cover and permafrost depth. Then they review the data and measurements...
Curated OER
Reflecting on Reflectivity
Students plan and construct a "mini-lab" to measure the reflectivity of different earth surfaces. They measure reflectivity of materials, including ice, soil, rocks, etc., and then extrapolate from what they have learned to consider the...
Curated OER
Sea State
Students explain the process of wave formation and analyze the relationship between the ocean and the atmosphere. For this oceans lesson students use buoys to cast real time sea state conditions.

Climate Change: Carbon Cycle
Students explore the carbon cycle. In this carbon cycle lesson, students discuss the four main reservoirs where carbon is stored and then discover the process through which each reservoir absorbs and releases CO2. This lesson includes a...

A Model of a Scanning Tunneling Microscope
Ninth graders explain how a scanning tunneling microscope works. In this chemistry activity, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their atomic model.
Curated OER
Stepper Motor
Students compare a stepper motor from a traditional motor. In this physics lesson, students summarize how it works. They build their own stepper motor and explore its uses.
Curated OER
Losing An Island
Students examine carbon dioxide and determine the impact of greenhouse gases on the earths spheres. In this pollution lesson students complete a lab activity to see the impact of gases on the environment,
