NATS 101 The World We Create
Remember, Project 3 Dues this Tuesday!
4/8
2
Todays Goals

• Give you an opportunity to
• Assess what you have learned,
• Reinforce central concept and ideas
• Be better prepared to complete Project 3.

3
Has anyone noticed the flow?
4
How about this flow?
5
Where are we now?

• Chemical Synthesis
• Polymers
• Properties Transformations
• Impact
• Societal Environmental

What do these concepts have in common? Lets
organize our ideas!
6
Build a Concept Map
Work with your partners to complete the map
(take 15-20 minutes) Fill in the concept map
with linking phrases and add directionality to
your connections. The upper portion of the map
relates to the first part of Unit 3, and lower
portion of the map relates to the second part of
Unit 3
Note You should use this to guide your thinking
for the next activity, so make sure you are
drawing valid connections

Question Generation

• You will work in groups to come up with questions
  for the game
• Groups will focus on different parts of the
  concept map to generate questions

10
Question Generation

• Your group should generate at least 5 quality
  questions per group of 2 or 3

(5 minutes)
11
Question Generation

• These groups will convene to quiz each other with
  their questions
• Your questions must be answerable

(5-10 minutes)
12
Question Generation

• Give your TAs your questions

13
Question Generation

• Your TAs will quiz the other subgroup with the
  generated questions
• Take this time to understand the content

(15-20 minutes)
Note TAs make sure to switch subgroups when
asking questions and to give back their questions
when finished
14
Lets Play a Game!

• Choose a spokesperson for your group
• ?
• Spokespeople

15
Game

• Three teams participate at a time and the game
  will cycle through all 9 teams (starting with A,
  B, and C)
• The team with the highest score wins 5 extra
  points on HW 9

16
Game

• When we ask the intro question, the first
  spokesperson to raise their marker and answer
  correctly gets a point and control

17
Game

• For the team in control, the spokesperson that
  answered it correctly will ask one of their
  questions to the team of their choice, that team
  will have a specified time to answer it

18
Game

• If the team gets the question wrong, the team
  that asked the question will have the opportunity
  to get a point, if they can answer their own
  question correctly

19
Before We Begin

• Any Questions?

20
