Today was all about graphing. We graphed Distance vs. Time and Speed vs Time for all of our Speedy Lab trials. Tomorrow we will finish this lab with a conclusion that ties together our tests, data, and graphs.
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.
