F in Signs

june-2008-059This won’t take long. Forgot that I snapped this photo last year as we were clearing out the stuff in the beach house before it was torn down. Always joke in our family about a summer trip out west when we were in Salida, CO and the street names were letters. Someone lives on the corner of F and Walnut, F and Elm, F and Broad–you get the idea. So . . . this vacuum bag just tickled my fancy and brought back memories of that trip. Any teachers out there know that you never have these two letters spend any time together and you never go from X to C!

Simple Things II

geoscience-008Today my four geoscience classes conducted one of my favorite activities of the year. It is so simple yet evokes such wonder and interest in the students. They simply investigate how two fluids of different densities (hot red water and cold blue water) interact. The preceeding day they had diagrammed warm and cold fronts. They come away from this activity fully understanding that fluids of different densities DO NOT mix easily. They have to diagram the set up before pulling out the divider and then draw an “after” diagram. They have to make predictions and geoscience-001support their ideas and then get to “test” their predictions right away. After the blue slide under the red, they reinsert the divider, mix the one side (to produce warm purple water) and go again. There is often a chorus of “that’s sick Mr. W,” which I know means they are finding the experience interesting.
