Spring Preparation

A common misconception is that the buds on trees form in the spring just before the leaves open up. However, by the time a tree’s leaves drop in the fall, its leaves for the next spring are already formed. Project Learning Tree’s activity “Bursting Buds” lets students investigate the stages leaf buds go through as leaves develop during the year. Adapt this activity by starting in the winter instead of the fall. For older students, have them work on identifying trees based upon the bud scars. This approach, sometimes in combination with bark, and tree shape, are ways people identify trees when they no longer have leaves.

Climate Change
According to most scientists, global warming is the single most important issue that affects our environment. Project Learning Tree’s activity, The Global Climate, is a good starting point for exploring this topic.

After students complete the student page “Saving a Ton of CO2” with their families, ask students what they can do individually to reduce CO2 every day (e.g. turn off lights when they leave a room, turn off electronics and unplug them when not in use, etc.). What can your school do?

What’s in the Air?
While Iowans don’t focus on acid rain, it still continues in parts of the country. Project WILD Aquatic’s activity “What’s in the Air” takes a look at acid rain, and the effects it may have on aquatic life and habitats.

Have students research Iowa’s role in acid rain. Does acid rain fall in Iowa? Do factories in Iowa release the pollutants described that can create acid rain? Are there any of these factories in your community? If so, how do they try to prevent pollutants from entering the air? Have these factories had to modify their production/disposal of waste to prevent air pollution since they were built?
