Today in science: After preparing their Lab Notebooks for the (new) “Bulb Investigation,” students were asked to construct 3 simple circuits and observe (and describe) the brightness of the bulb (or bulbs) in each circuit. At the end of the lesson, the PATTERN we observed in this investigation could be stated as follows:
E period: As the number of bulbs in the circuit INCREASED from 1 to 3 bulbs, the brightness of the bulbs DECREASED from “fairly bright” to “no visible light at all.”
F period: As the number of bulbs in the circuit INCREASED from 1 to 3 bulbs, the brightness of the bulbs DECREASED from “fairly bright” to “a barely visible light/glow.”
This observed pattern is the basis for the question assigned for homework to each student in the Google Science Classroom: What do you think is the reason (explanation) for the pattern you observed the when building the 3 bulb circuits (001, 002, 003) in Monday’s science lesson?
Homework: In their Google Science Classroom, students will see that they have been assigned a single question to which they must respond (and submit/turn in). All student responses must be made in the Google Science Classroom and not through Veracross or email.
Tuesday & Thursday, January 26 & 27th
Today in science: Students were asked to redraw the 1-bulb circuit they built in yesterday’s bulb investigation, but this time with a focus on atoms and elements…the elements commonly found in batteries and the metal atoms that make up both the connecting wires and the bulb (filament). This meant taking notes and drawing some atom diagrams in their Lab Notebook, but also learning how to decode the entries in the periodic table of the elements not only to determine how many neutrons and protons can be found in the nucleus of different kinds of atoms, but also to determine how many electrons can be found outside of the nucleus in these same atoms. With the help of a physical model in which students were asked to form a connecting wire with Dr. Merritt acting as the ‘battery,’ students were asked to see electricity as a series of expulsions and collisions of electrons. The role of ammeters was also explained in terms of how they ‘count’ the numbers of electrons passing through a point in a circuit second.
Tuesday homework: There is no science homework tonight.
