Water’s Going On?
Every molecule of water that was present when the Earth’s oceans were formed millions of years ago is still present today. That means the water you drink is the same water dinosaurs drank! Most of the water consumed in the United States comes from groundwater. Groundwater takes hundreds or even thousands of years to replenish. Water is important to every living thing on Earth which is why it is so important to conserve and protect our water resources. Use Project WILD Aquatic’s “Water’s Going On?” to track your own water consumption!
Young Child Extension
Set up stations for children to explore water. Supply scoops, cups and other tools for filling, dumping and exploring. Supply cold water, warm water and ice. If possible, boil water to show children water in its gas form – steam. Ask children: Do you use water? What do you use water for? Who else uses water? Do animals use water? Where is there water? At your home? Outside? What do you like about water?

Invasive Species
Have you ever heard of zebra mussels? Or purple loosestrife? How about gypsy moths? There is thing that all of these species have in common – they are all invasive species. Invasive species are non-native species that overrun an environment where they have been transplanted. Throughout history people have intentionally and unintentionally moved species from their original environments to new ones. These non-native plant and animals are not always harmful, however, some of these new species cause problems when they outcompete the native species. Explore the world of invasive species with Project Learning Trees “Invasive Species”! February 26 to March 3 is National Invasive Species Awareness Week. Check out the NISAW website for things you can do to make a difference! http://www.nisaw.org/2012/ways_to_observe.pdf

Young Child Extension
Young children can help count birds too! Take kids on a walk around the school yard or observe birds through the windows of the classroom. Keep a chart to track the number of birds sighted. Put a bird feeder up outside the classroom window to attract birds for children to watch. Or help the children make pinecone bird feeders to hang up themselves. Use Growing Up WILD’s “Bird Beak Buffet” to learn more about our feathered friends!
