Sun Dials and Bridges

We have been focusing on observing shadows in science lately. Each week we are measuring our shadow and observing how the length is changing. Eventually, we will plot this on a line graph and predict how long it will be after spring break. Today we used chalk to draw our shadow 4 times throughout the day. Many students believed the shadow would only get smaller, not necessarily change direction. The activity takes us right into building a sun dial next week. Our last College of Engineering lab took place today, led by a UNR student. The focus was on different types of bridges, with the lab directed on building a suspension bridge.
