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.
Students will engage in a hands-on activity to help them consider what students in a tropical climate do to prepare for recess compared with students who live in the interior of Alaska.
Objectives
Students will:
* Compare what students in a tropical climate do to prepare for recess with students who live in the interior of Alaska.
* Learn
This lesson is intended to have the students think about the animals of the Arctic and which ones they think are the largest. This will help with misconceptions of some animals being smaller than they think and you sneak in the scientific method and measuring skills while doing this lesson. Students will love actively participating and comparing themselves
Students will conduct quantitative and qualitative observations on living organisms. By recording careful measurements, making and testing various hypotheses, on super mealworms, students will gain some understanding of how wildlife researchers conduct their studies.
Objective
Students learn to take measurements on living organisms and use those measurements to consider the health of the organisms.
Dividing the class into Little auks and predators, students complete survival game for several seasons. After tallying up total volume of food collected, survival rates of the chicks can be graphed and analyzed.
Objective
Students will be able to experience the hazards that Little auks must avoid in order to survive. Students will understand the value of
Compare what students in a tropical climate do to prepare for recess with students who live in the interior of Alaska. Learn several consequences caused by sub zero temperatures. Create awareness that people are able to prepare for a cold environment by adding layers of clothes.
Objective
Compare what students in a tropical climate do to prepare
