Week 4 Tuesday
Challenge: Superman vs Batman
Instructions: If you're looking to start a fight on a playground, ask a few of the elementary school kids would win if Superman fought Batman. It would be a close fight, for sure, but there's little agreement about which character would remain after a head to head battle. At your tables you should decide the winner and what powers and properties of that character tipped the balance for your group. Start by considering each hero's
- mobility
- fighting abilities
- fighting style
- major losses and
- vulnerabilities.
You might want to list the strengths and weaknesses of each character or you might want to read up on the histories of the heroes and their battles. After 30 minutes we will reconvene as a class to list the attributes that each table has considered and to tally the Superman vs Batman votes. May the best superhero win.
Follow-up: History of flight
