Lesson 4: Investigating Streams (PT)
Streams originate from rain and snow melting. Springs feed into streams when water slowly under the ground finds a way to earth’s surface/ Gravity causes rainwater to soaks into the soil while the remainder flows downhill causing tiny channels/rivulets that gradually deepen and cause gullies to form. Eventually, continued precipitation and soil erosion cause a stream and shape the valleys through which they flow. Downstream, other small streams/tributaries join the flow and make a river and eventually rivers can form enormous land features (exGrand Canyon).)

6. Make a Popplet graphic organizer to show the effects of rain and streams on land (as observed in lessons 3 & 4) and how water from the stream changed the land. Add a photo of water changing land and a pictures of the aftermath of rain flowing on land which illustrates erosion (DOK 3) (SEP 8)
