After a little over a semester of intentionally including multiple experiments every chapter, I wasn't nearly as intimidated when this file stared back at me from my chapter outline last week. I printed out the book's worksheet, gathered some resources for the next day and went home. The morning of, I decided to rework the task a bit (a have both the original and my file at the end of this post).
The students did swimmingly. Every student was on task for most of the period. The class did well seeing the relationships between the initial height of the water and the y-intercept as well as between the number of cubes added and the rate of change.
