Great first day of school! It was so nice to meet all of the new 8th graders and get our science year off and running. In class students made ball and stick models of methane, a flammable gas, and then Mr. Powell made soap bubbles filled with methane. Students made some predictions about the behavior and properties of the methane bubbles and after a demonstration learned that they are highly flammable! We also covered some class guidelines and procedures. Please BRING A COMPOSITION BOOK to class tomorrow.
GOLD TAPE QUESTION: Write out the chemical formula and draw the chemical structure for the strongest acid in the world.
The only clue left at the crime scene is a mysterious white powder. Students will analyze 6 different known powders, associated with 6 different suspects, to determine the identity of the whiteboard thief! This activity is modified for 8th grade, based on The Proof is in the Powder, originally designed for the International Exhibition of Sherlock Holmes. Students will finish their investigation tomorrow and complete this assignment by writing a crime report that is due Monday.
Mr. Powell is an 8th grade Science Teacher in Western Colorado.
