Scientists in Siberia are seeing trends of more severe and widespread wildfires. By observing and measuring larch forests, they are trying to understand how the forests are changing. What do these trees need to survive? Are they getting what they need? Students will plant lodgepole pine seeds providing some with all the necessary components for survival and others missing
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
Students will learn to:
* Observe and record weather patterns
* Process data by creating graphs/charts
* Compare actual weather data from the Siberian Arctic to local weather patterns, draw conclusions and make future predictions concerning weather patterns.
Big Idea
Why do people need to track weather over time?
Lesson Preparation
You will need a thermometer, tracking calendar, and
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
