In a far away city called Grant City, the main export and production product is the steel widget. Everyone in the town has something to do with steel widget making and the entire town is designed to build and export widgets. The town hall has the instructions for widget making, widgets come in all shapes and sizes and any citizen of Grant can get the instructions and begin making their own widgets. Widgets are generally produced in small shops around the city, these small shops can be built by the carpenters' union (whose headquarters are in town hall). After the widget is constructed, they are placed on special carts which can deliver the widget anywhere in the city through specialized widget railways. In order for a widget to be exported, the carts take the widget to the postal office, where the widgets are packaged and labeled for export. Sometimes widgets don't turn out right, and the "rejects" are sent to the scrap yard where they are broken down for parts or destroyed altogether. The town powers the widget shops and carts from a hydraulic dam that is in the city. The entire city is enclosed by a large wooden fence, only the postal trucks (and citizens with proper passports) are allowed outside the city Performance Task Create your own analogy of the cell using a different model. Some ideas might be: a school, a house, a factory, or anything the student may use as a representation. Announcements Long Quiz 1 (1st meeting) Topic: Cell Theory Long Quiz 2 (2nd meeting) Topic: Cell Ultrastructure BRING 1 FILLER NOTEBOOK Announcements Lab Activity next week (2nd Week of 1st Quarter) Bring the following: microscope slide methylene blue (per class) tissue paper newspaper clean toothpick lab gown (not required, but with additional points if with lab gown) Short bond papers Pencil and coloring materials
