Scientists in Siberia are seeing trends of more severe and widespread wildfires. Larch seeds are dispersed by wind. Experimentation is currently underway to determine distances larch seeds can disperse from viable, mature larch trees. Students will explore how various types of seeds are dispersed to get what they need to survive.
Timeframe: 90 minutes
Grade: K-2
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.
The inspiration for this lesson was to encourage students to experience and appreciate nature with their senses while addressing a Common Core State Standard. This activity allows students to infer what an object is by using all senses but sight. Phonemic awareness is a skill difficult to isolate outside of the context of reading; the audio portion of
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
This First Grade unit on the bowhead whale has been created to support the knowledge of children living within a whaling community. The unit focuses on the basic components of understanding the bowhead in a more scientific manner. Although my students know the bowhead in a uniquely intimate way because of their environmental and subsistence circumstances, our goal
This engaging topic and active game is inspired by a long-term scientific study of Black Guillemots nesting on an island near Barrow, AK. It introduces the life cycle of the Black Guillemot, how it raises its young, and the adaptations it is making to adjust to life in a changing Arctic.
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.
This lesson introduces students to krill, their importance in ocean ecosystems, and the physical structures that make up the krill body. The students will then use the principles of a "floater" species and design their own krill, hopefully having a class competition to see who can build a better krill.
Objectives
Students will understand the importance of krill in
Rings of life is a comparative lesson allowing students to investigate growth rings in walleye Pollock from the Bering Sea and Ponderosa Pine trees.
Objectives
Students will be able to compare and contrast growth rings on fish and trees, showing just one of the tools scientists use to monitor the health of different ecosystems. Students will also be able
