Today we continued our investigations with simple machines and pulley's. We used our Physics Stations to learn how to calculate mechanical advantage of a pulley system.
Later we used our Physics Stations to answer the question; What impacts the frequency of a pendulum system? We divided into groups that were based on three different claims; Group one claimed it was the weight at the end of the string. Group two claimed it was the length of the string, while group three claimed it was the angle of release. The results were fascinating
Before lunch we began our explorations with magnets. We focused our investigations on what materials interact with magnets. We began to investigate and solve the mystery of the Canadian nickel. After lunch we studied magnetic fields. We used iron filings to see what was once invisible. We explored the shapes and outlines of a variety of magnetic fields. We then had the magnets interact with each other to see how their magnetic fields were affected.
Our field trip today would take us to IB3 ( Industrial Building 3) where Fermilab's efforts to develop superconducting radio frequency technology is well underway. Upon our return we spent the end of the day investigating electricity and seeing the connection between magnets and electricity. We will continue exploring circuits tomorrow.
