Sun Matters

From Step 2007 Wiki

We decided to incorporate the concept of global climate change into a third grade lesson on Alaskan plants. Since there is measureable evidence that average annual air temperatures are rising globally, we wondered how that would affect the soil temperature in which Alaskan plants are growing. In our lesson, students explored this idea by measuring and comparing plant heights and temperatures of the soil in which various plants were growing. They compared plants growing in direct sunlight to plants growing in the shade.
