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.
In this set of lessons, students have the opportunity to think like scientists as they examine actual data related to Arctic ground squirrels, organize it in logical ways, and make inferences based on the data.
Objectives
Students will develop an understanding of some of the ways scientists use and organize data.
We want students to develop the habits, traits, and qualities of effective scientists. What better way for them to learn what these traits are than by hearing from actual scientists? In this lesson, students watch video interviews with four Arctic scientists from the University of Alaska, notice what types of work scientists do on a daily basis, and make
Plan and run a family fun afternoon or evening with several hands-on activities. Students help run the activity stations and share what they have learned about the Polar Regions. A great culminating activity for a unit on the Arctic, Antarctica, or both, and a fun way to involve families in the learning experience.
