1. Bellwork: Please get out your ‘green’ SLOT and work on Day 4 SLOT is due today! For information about the retake for the Blood Typing Quiz, please check my blog! iblog.dearbornschools.org/wachholz The retake form and all of the requirements can be found there. (Work on it over break and it won’t be a big deal!)

2. Today’s Learning Targets I can design an experiment to test a hypothesis. (claim) Gather data during an experiment (evidence) and draw conclusions from the data. By the end of the unit, I can explain how blood stain patterns are a function of velocity, direction, angle, surface, and the height of the fall. Blood tells a story…it is up to us to interpret it!

3. Essential Question: How is the size of a blood drop effected by the height in which it falls?

4. Directions: 1.Get with a group of no more than 4 people. You will need a white board and dry erase marker. 2.Form a hypothesis (claim) about the essential question. (Height vs size of blood drop) 3.Design an experiment to test your hypothesis and write the procedure on your white board. 4.Get your procedure approved, complete the lab, and gather data (evidence). 5. Take a picture of your whiteboard, put your names on any index cards, and clean up.
