We will meet at the western edge of Silver Lake Beach.  The Trees For Tomorrow staff will teach us how to rake the lake bottom at the edges to catch the critters that live there.  We will work at identifying the critters and analyze the health of the waters based on the critters we find.  We will learn to be clean water heroes.  There is a limit of 25 kids.  Kids ten and under need an adult to accompany them during the activity.  You will want to wear weather-appropriate clothing and sunscreen.  Sign up for this activity at the Library.
