This lesson describes how decomposition happens, and the role of microorganisms in this process. The animation, which runs for 3:23 minutes total time, covers information that students may or may not be familiar with. Here is one suggestion for working your students through the animation. By actively taking notes during the animations, students can engage in a dialogue with the
The purpose of this lesson is to highlight the importance of the structure of a leaf at its implications for how it decomposes. The animation, which runs for 2:03 minutes total time, covers information that students may or may not be familiar with. Here is one suggestion for working your students through the animation. By actively taking notes during the
The purpose of this lesson is to highlight the importance of the Carbon Cycle in the natural cycles of photosynthesis and respiration. It also models how human activity can alter the carbon cycle. The animation, which runs for 2:56 minutes total time, covers a large amount of information that students may or may not be familiar with. Here is one
Through investigation, you will determine which solution has the highest density.
Objective
To determine, through experimentation, which of a variety of solutions has the highest density.
Preparation
Background: The waters of the ocean are constantly moving in many different ways. The surface of the ocean rises and falls in rhythm. These movements, in the form of
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
We hope that this activity will be completed by a multitude of classrooms, students, scientists, and teachers around the world in celebration of International Polar Week - a global celebration of the Polar Regions during the equinoxes each year. Please find more information about this activity, including translations in many languages at [Flakes
Glaciers are slow-moving masses of ice that exist where more snow falls than melts. They occupy about 10% of the Earth’s land, mostly in Greenland and Antarctica. Here, glaciers can be as much as 2 miles thick and weigh more than millions of tons. As they move, glaciers can widen and deepen valleys, flatten forests and grind boulders
To compare the conductivity of freshwater and seawater. This is a lab activity, and students should be taught appropriate safety measures, including eye protection and safety while using electricity.
Procedure
1. Use the table in attached PDF to record your data.
2. Put 100 mL of 3.5% NaCl solution into a 250 mL beaker.
3. Attach 2
Sea ice, the thin layer of ice that covers most of the Arctic Ocean and surrounds most of the Antarctic continent, represents a distinctive feature of our planet. The attached flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of information about sea ice including sea ice formation, movement, monitoring, seasonal patterns, and forecasting. A follow-up
This PDF handout and activity provides background information about polar weather and climate followed by an activity to help students consider their own local weather vs. polar weather. Students will observe the weather where they live and report on basic meteorological data such as air temperature, precipitation, wind etc. and use a weather map to compare their local weather to
