Field trip!

Today we traveled to Catalina State Park to study macro invertebrates in streams. Macroinvertebrates are small living organisms that you can see with the naked eye and that don't have backbones. We caught little creatures from a stream and used a "key" to figure out what species we had caught. Today we caught damselfly larvae, dragonfly larvae, whirlygigs, Sunburst diving beetles, mayfly larvae, water spiders, and we even found tadpoles and frogs! The fact that this stream had so many species living in it, told us that it was healthy water and did not have many (if at any) pollutants. I have learned so much about water in the past two days! Check out my pictures! :)
