STRAW Restoration Reflections - Connecting Our Landform Investigation to Our Field Trip at Stafford Lake
by Jenna, 4th grader at Loma Verde Elementary School

On April 20, 2009 our class did a science project about erosion. Miss Golden gave each table a bag of dirt so we could pour it in a stream table. So when we poured it we had to scrape the sand over to the other side and the tool was called the angle. Oh and the stream table had a little hole at the end so water can come out... but we're not there yet! So we put a ruler right on top of the sand and one person from each table went up to get a cup of water with a hole on the bottom. We put it on the ruler so when the person poured the water in the cup, the water would dribble down the hole. The water would bring the sand with it part of the way, and the water would go through the hole and into a basin. Then, Miss Golden left them outside for a day so they will dry.

We set the sand up like a plateau (we needed to keep the sand flat). When we let the water drip out and it was all done and dry the sand made a canyon and the water made a little river. Here are a few pictures of our landforms:



=Remember Our Restoration at Stafford Lake in October??= =  = =Discussion Question:= =Think about what you saw in yours and your classmates' stream tables and what observations you recorded in your Science Notebooks. Tell how your investigation relates to our Restoration Field Trip at Stafford Lake.= (Please type your answers on this page's [|Discussion Board] )
