B3.3 Muscle and motility: grass skirts
22 quick questions on muscle and motility, a higher level subtopic, each answered in a word or two. Print a sheet for each team, a key for the checker and a tick sheet, then tape the sheets to the board and race.
How it runs
- SnipA runner cuts one strip off the bottom of their team’s sheet.
- Answer as a pairBack at the table, they write the answer on the strip. No books.
- Get it checkedThe checker reads it against the key: you, or a student holding it.
- Back for the nextA tick earns the next strip. Wrong? Back to the table to try again.
