This is the best activity I've ever done at school- EVER!!! This was a comment by a student this week as we found out about the complexities of density in a sink or float activity. Student's predicted before testing items like cantaloupe, grapes, oranges, wood, plastic, glass, etc. Who knew that tiny rocks would sink, but the cantaloupe would float???? Students did a long list of items, before writing about their results the next day! All of this talk of differences in density came about when Archimedes had to solve the problem of the density of the king's crown. Get your student to tell you about it.
This next week students will be making a budget plan to review place value and rounding. Can they keep to the budget? We'll see!
