This is the only icebreaker that I use with my high school science students! I've used it for over 5 years and it is always my favorite day of the year. This icebreaker activity allows you to 1) talk science on day one 2) randomly group students for your seating chart 3) spend time getting to know your students and 4) allowing them to get to know you!
Let your high school or middle school science class solve the crime while they practice applying the scientific method! Lab instructions, student and teacher worksheets, and materials lists for the activity are included.
