The 3-5th grade standing where they figured Pluto (smaller than a pinhead) would be if the sun (a soccer ball) was at the crosswalk in front of the school. Each pace that they took was approximately one yard which equaled approximately 3,600,000 miles. They had to walk over half a mile from the sun to Pluto! They learned that our solar system is enormous and that to create a model of it (to scale) you would need a lot of room!Wednesday, April 7, 2010

Field Report for Mt. View Ditch, 4/2/10
On Friday, April 2, our class went to Mt. View Ditch to decide where to collect data. We looked at five different places near the ditch and finally decided on a place near Venetta Rd. The sky was blue the whole drive down to the ditch and also sunny while we were there.
The salinity was pretty low, the average was 5ppt. Our data is a little messed up, so we don’t know what the water temperature was. The data sheet says that it is 12˚F, but that doesn’t make any sense, since the ditch wasn’t frozen. We don’t know if that 12˚ was Fahrenheit or Celsius, or if the measurement was even 12˚ at all! We caught nothing in the nets, and the bucket had a leak so it didn’t hold any water, so I guess it was good we didn’t catch anything. When we were done collecting data we wrote and drew about our trip to Mt. View Ditch.
Mt. View Ditch is man-made and was dug when the road was being built. It eventually empties into Harry Hall Creek, which we took a trip to on the 15th of January.
Once we were back at the school we unpacked the backpacks and washed the tools that got wet and then let them dry out. Our next trip this Friday will be to Rink Creek.
Our class has one question for anyone reading this; we saw some ground cones on our trip and we were wondering, what do ground cones eat?
