Kelvin Scale

With so many students out of class on a field trip on Friday, we switched the order of Lesson 52 and moved ahead to Lesson 53.  We will return to Lesson 52 tomorrow after students have the opportunity to read through the lab and complete the pre-lab. Today, class began with a short SciShow video about the Kelvin Scale:

After the video, students worked through the Lesson 53 Worksheet.  The worksheet refers to a simulation which can be accessed here: Gas Properties (PhET simulation which requires Java).  The Lesson 53 PowerPoint is available for review by clicking here.  For homework, students should complete textbook questions 1-7.  Notes from class are provided below:

Biogeochemical Poster Project

We began the week with a brief review of what to expect on the quiz scheduled for this Friday.  Class notes are shown below:


This week, students will work in groups of three students each to create a poster representing biogeochemical cycling.  For the project, students will create a poster to model the water, carbon, nitrogen, phosphorus, and sulfur cycles on a poster with an emphasis on including the ecosystem of Yellowstone National Park where possible.  Students will have access to the class textbook and the class set of laptops to conduct their research.  Students will also receive the Nutrient Cycling POGIL worksheet packet that will provide them with additional information about the process of carbon (C), water (H and O), nitrogen (N), and phosphorus (P) cycling.  Sulfur is often included as a component of the biogeochemical cycle, frequently appreviated as the CHNOPS cycle.  To help keep student projects moving forward, a variety of resources will be posted here for review.

Crash Course: Carbon and Water Cycles

Crash Course: Nitrogen and Phosphorus Cycles

Bozeman Science: Biogeochemical Cycles (includes the Sulfur Cycle)

The Global Carbon Cycle – a website with data about global carbon cycling with actual numbers that need to be added to the student posters.

Water Cycle – USGS website providing a robust review of hydrologic (water) cycle vocabulary, a presentation of the cycle itself, and data students will need to add the actual amount of water stored in various locations on Earth.

Texas A&M University has a website with pages devoted to explaining the Nitrogen Cycle.  Additional in-depth information about the Nitrogen Cycle is available on the Nature Education Knowledge Project website.

Phosphorus Cycle – information about the cycle and a nice graphic from the Shmoop University website.

Sulfur Cycle – a presentation provided by The Environmental Literacy Council
