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.
This lesson allows students to consider navigation around Antarctica, where longitudinal lines converge at South Pole. Through this study, students should learn about polar stereographic projection, satellites, navigation using various instruments, Antarctic geography, and NASA’s Operation IceBridge airborne mission. In the first part of this 55-80 minute lesson, students will be faced with a dilemma. Their task will be
NASA’s Operation IceBridge (OIB) flies airborne missions each year over both Polar Regions, collecting ice thickness and extent data on glaciers, ice caps, ice shelves and sea ice. This data is useful to many disciplines studying climate, weather, ocean circulation, sea level and many related fields. The National Snow and Ice Data Center (NSIDC) houses and organizes the data
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 Revitalizing Power of Teacher-Researcher Collaboration
The nature of science is continually moving us forward; from a fresh set of findings we rush ahead excitedly to the next batch of questions. From this continual pursuit, new ideas, methods and instruments are designed by scientists and technicians at a rapid pace, in turn yielding new data. As science teachers, we need
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
