9. Mars Probe Crash Pre and Post Assessment

10. PRE ASSESSMENT: What form of measurement system are you more used to? 1. Metric (meters, liters, grams) 2. English (feet, pounds, inches, etc) 3. I am equally used to both of these systems 4. I am used to a different system

11. PRE ASSESSMENT: Imagine you know the Metric and English systems equally well. Which do you think is a better system to use? 1. Metric (meters, liters, grams) 2. English (feet, pounds, inches, etc) 3. Not sure – I need to learn more before deciding

12. PRE ASSESSMENT: Do you think the entire world should be obligated to use one, universal, worldwide system of measurement (EITHER metric, OR English, etc)? 1. Yes 2. No 3. Not quite sure – need to learn more before making a decision

13. As a class, we will read the articles… Expect to stop during the articles for comments, questions, and feedback. Feel free to highlight, take notes, etc. SHARE what works best for you when you are reading a text for understanding These are yours to keep – they are NOT graded! You may bullet point for the questions (do not have to use full sentences)

14. Debate (pending time) 2 groups – pro/con for the worldwide use of the metric system _____ minutes to discuss as a group and use smart phones for additional research Each individual has the opportunity to state 1 reason for their decision, followed by evidence based reasoning. Once an individual from one group has spoken, an individual from the other side will have a chance to rebut (once again, using evidence!) You cannot speak again until at least ____ people on YOUR SIDE have spoken You may change sides at ANY TIME by walking to the other group.

15. POST ASSESSMENT: Imagine you know the Metric and English systems equally well. Which do you think is a better system to use? 1. Metric (meters, liters, grams) 2. English (feet, pounds, inches, etc) 3. Still not sure!

16. POST ASSESSMENT: Do you think the entire world should be obligated to use one, universal, worldwide system of measurement (EITHER metric, OR feet/pounds, etc)? 1. Yes 2. No 3. Still not sure!
