We had a great trip to the Tacoma Nature Center for the Water Sleuths presentation. The students investigated a model of how rainwater runs into the sound and were able to see that pesticides, waste water, and other pollutants affect it.
They also tested the water from Snake Lake for nitrates and phosphates, as well as the ph level.
Students counted the number of animals heard and seen as they walked the half mile to one of the bridges over the lake.
Once they got to the lake, they used secchi disks to check the water clarity of the lake. Ask your child about the secchi disks!
It is a good thing they didn't need to count all of the mosquitoes that swarmed them when they reached the bridge! They were everywhere!
Once they had gathered all of their data, they were able to deduce that Snake Lake is healthy!
