Hi folks,
Today we began the next part of our energy unit with is energy in motion, in other words, waves. Today we worked on the concept of frequency and hertz.
In order to work with this, the students created 3 pendulums. One of which had a frequency of .5 Hz, one had a frequency of 1 Hz and the last had a frequency of 2 Hz. From their data, they then predicted what length of string would have a frequency of 1.5 Hz.
Extra Credit possibility. Continue working with pendulums and do a lab exploring one of the many variables you thought of today during class. For example, changing the weight of the bob. Does the height of the swing matter? Does interference of the swing matter.
