We finished heat and light activities this morning before going on a field trip. We began by testing the heat conductivity of various materials. The race to melt a pad of margarine was won by aluminum with brass in second followed by steal. Wood never finished the race!
We then discussed solar energy and how important shadow lengths are when telling time.
We used the fermi sundial and then retreated to the lab to model the passage of time across the United States using a flashlight and golf tee. We trekked from the science center through the forest to the Minos and Minerva projects. Upon our arrival we met a brilliant Brazilian scientist named Mateeus Carneiro (mateusfcarneiro@gmail.com ) Mateus took us 300 feet underground and showed us several detectors and explained in detail each project's purpose and what they hope to learn.
In the afternoon we began our exploration of magnetism and electricity. we created magnetic fields.
We even reproduced the fermi lab symbol; the quadrupole. Students identified materials that interact with magnets and what magnets can be made from different materials. They also have varying strengths. We learned that all metals are not attracted to magnets and that Canadian nickels change their metal content over the past 40 years. From there we moved onto learning about electricity. We made a human circuit and then made our own circuits with wires and aluminum foil. The push of electrons is called voltage and that volts have an additive property.
