 * <span style="font-family: Arial,sans-serif; font-size: 10pt;">Assessment: || <span style="font-family: Arial,sans-serif; font-size: 10pt;">Question:
 * 1) <span style="font-family: Arial,sans-serif; font-size: 10pt;">1. Of all the evidence in the classroom, which do you think should be studied first and why?
 * 2) <span style="font-family: Arial,sans-serif; font-size: 10pt;">2. What evidence do you believe is most important and why?
 * 3) <span style="font-family: Arial,sans-serif; font-size: 10pt;">3. What predictions can you make about how the evidence will fit into the crime?

<span style="font-family: Arial,sans-serif; font-size: 10pt;">Ask students to write their theories of the crime in their notebooks.
 * 1) <span style="font-family: Arial,sans-serif; font-size: 10pt;">1. What happened and how did it happen?
 * 2) <span style="font-family: Arial,sans-serif; font-size: 10pt;">2. Who had a chance to do it in the way the evidence suggest?
 * 3) <span style="font-family: Arial,sans-serif; font-size: 10pt;">3. Why might the person have committed the crime?

 * 1) <span style="font-family: Arial,sans-serif; font-size: 10pt;">a. Pretend a crime has been committed in your bedroom! Follow these steps to secure the scene:
 * o <span style="font-family: Arial,sans-serif; font-size: 10pt;">Make a sign identifying it as a crime scene.
 * o <span style="font-family: Arial,sans-serif; font-size: 10pt;">Make observations of the room and take photographs, if possible.
 * o <span style="font-family: Arial,sans-serif; font-size: 10pt;">Measure the room and begin your rough sketch.
 * o <span style="font-family: Arial,sans-serif; font-size: 10pt;">On sketch, draw, in windows and doors, which are your fixed points.
 * o <span style="font-family: Arial,sans-serif; font-size: 10pt;">On sketch, add furniture.
 * o <span style="font-family: Arial,sans-serif; font-size: 10pt;">Identify the evidence, measure it from fixed points and include it in your drawing. ||
