Day 4 of Read To Us Week brought us two awesome scientists! Tammie Wilson and Chloe Ryan joined us to tell us about their experiences working in the shipyards of Portland. Tammie explained how she helps to keep our water clean by keeping metal and other toxic materials out of the river when ships are being built. Chloe told us how she helps to protect our air by monitoring ships when they are painted. We are so glad we have great people like Tammie and Chloe that work so hard to help keep our environment clean.
