Most students, regardless of their grade level, live “in the moment,” concerned only with factors and issues that have an immediate and direct impact on their lives. This is, to a large degree, understandable given the pressures, demands, responsibilities and constraints placed on students during their high school academic years. However, as teachers, we are required to not only
To begin the process of educating my students on my upcoming expedition to Antarctica, I introduced an activity entitled, “Questions about Antarctica…It’s What’s for Dinner.” In this assignment, small groups were asked to develop a list of 10 questions about anything - weather, clothing, wildlife, geography, geology, oceanography - related to Antarctica. Each question was worth up to 10 points
My name is George Hademenos and I am a physics teacher currently in my 17th year at Richardson High School in Richardson, TX. My primary instructional mission as an educator is to ensure that not only are my students exposed to the knowledge, content and lab experiences consistent with a science course, but that they are also
This lesson focuses on the diffusion of gas molecules across the cuticle membrane of sea spider legs and the role body size plays in the ability of sea spiders to uptake gases. Students construct model sea spider legs of varying diameters and use them to investigate the relationship between surface area-to-volume ratios and diffusion.
Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
Impacts of a field experience on teaching high school science
Early in my teaching career, I learned that authenticity is essential in creating working relationships with my high school students. By showing them that I am a human being with experiences, ideas, dreams, and opinions, I’m able to connect in ways that invite their attention as I teach skills
The Importance of Teacher/Researcher Collaboration
It can be a humbling experience to admit that something isn’t easy, or that you don’t understand a topic or concept. It is harder still when you are surrounded by knowledgeable individuals and expected to explain their research in an accurate manner. While humbling, it is educational. Through learning about concepts such as trace metal
This lesson incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify
In a “March Madness” game of survival of the fittest, will your microbe and its genes survive the test of changing conditions on Planet Earth and beyond? Students choose genes from a “toolbox” and pit their microbe against their classmates’, using critical thinking and argument writing to determine the microbe with the best chance of success. Based on PolarTREC
