Whodunnit?
Chemical & Physical Properties
Topic:
Time Range:
Matter
10-20 Minutes Supplies:
Pencil & Paper
General Procedures:
A.) Give students a Whodunnit Worksheet. Students will need to answer the 10 multiple choice questions about
the topic. Each correct answer will result in a clue. Students will check off the Players, Last Known Whereabouts
and Methods that are accounted for. The one remaining from each column is the correct solution. In this case it
should be:
“Mrs. Bio electrocuted the victim in the pool.”
B.) Print out the “Clues” and cut them out. I suggest you laminate them for future use. Spread them in different
locations in the classroom and turn the students loose. Have teams of 2-3 circulate and attempt to figure out the
clues. They can record the answers on the handout. You can require they write complete sentences. Once they
think they have all the pieces, they can come to you to check their answer. If they are wrong, let them figure it
out ☺
An alternative “Clue 10” is provided in the event you want a different result for different class periods.
