This will be our first full week on the Electricity and Magnetism Unit and now in the 2nd semester. As I mentioned in class last week, due to my illness, the homework that was due on Thursday has been moved to Monday (January 19). So the homework and DUE date for this week is as follows:
Monday, January 19: Pick three of the following seven scientists and for each write 2-3 sentences on their contributions to electricity: Benjamin Franklin, Thomas Edison, Michael Faraday, James Watt, Allessandro Volta, Andre-Marie Ampere, and Hans Oersted.
Thursday, January 22: Many people are switching from incandescent to compact fluorescent light bulbs. The homework is as follows:
- Count all the light bulbs in your house. How many are there in total? Of the total, how many of them are incandescent and how many are compact fluorescent light bulbs (and also halogen)?. Put the number of bulb types in a bar graph form.
- Finally, how are compact fluorescent light bulbs different than incandescent light bulbs in terms of expense, average bulb life, and efficiency? Why are people switching? Answer these questions in complete sentences.
-Mr. Pfiester
PS. Please bring in a lemon to school either Monday or Tuesday. We will be creating lemon batteries and try to light small LEDs with the electricity produced.
