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
In this activity students learn about varves, annual sediment layers found in lakes. Students will analyze authentic varve data from New England in order to correlate data from three different geographic locations .
Objective
Students will analyze authentic varve sediment data and create a graph of varve thickness. Students will use their results to make inferences about
This website provides information on the Arctic ground squirrel including facts and pictures explaining the adaptations the squirrel has to survive the harsh Arctic winters.
A great resource that includes content and lessons for all grades. You can sign up to receive seeds that have either been in space or on Devon Island plus seeds that have not been exposed to harsh conditions. Students will be able to participate in a blind study to see if they can determine which seeds are the harsh environment
