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
The Importance of Teacher/Researcher Collaboration
Collaboration such as this offers a window into the science rarely seen by teachers and their students. It allows the public/students to experience, in real-time, relevant data collection of the 21st century. Furthermore, experiences such as these demonstrate the universal factors of the scientific process. It does not matter if we are practicing science in
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
Just as the increase in atmospheric CO2 is causing the global air temperture to rise, the container with the added CO2 will trap more heat inside and will show a higher internal temperature.
Overview
This activity/demonstration can be used directly following lessons on greenhouse gasses and their effects on warming the atmosphere by allowing shortwave UV energy
In this one hour presentation, PolarTREC teacher John Wood explains the scientific work in the Carbon Balance in Warming and Drying Tundra expedition from Healy, Alaska.
The local on-line newsletter interviewed Mr. Wood over the phone and talks about the upcoming expedition to the interior tundra of Alaska and how it will involve the students at Talbert Middle School in Fountain Valley.
