Be a Junior Detective part 3


Practice matching a bite in a cookie to samples of your suspects dental indentations....this can be fun!

you will need
  • large soft cookie that doesn't contain chocolate chips or nuts ( sugar cookies are great)
  • Dinner size styrofoam plate cut into 6 equal wedges ( 1 plate for 3 suspects)
  • scissors
  • pen or marker
Have some take a single bite from the cookie
Gather several willing accomplices and have one person take the bite without telling anyone telling you who did it
Stack the styrofoam wedges in pairs and then cut off the point of the triangles about 1 inch from the tips
Have each suspect bite down on a set of wedges. ( note which is the top and which is the bottom of each pair and who it belongs to)
Now compare the overall size and shape, as well as the individual tooth impressions of each bite mark and those in the cookie.
Can you find the match?

**Missing , crooked, or new teeth, along with the overall shape of a person's mouth, create a unique impression. **
