I am always looking for math in the real world as that interests students the most. A video hyperlink is included to introduce your students to Clara May, putting a face and image with the problem.
My daughter, Clara is fed with a g-tube and I deal with unit rates every day. Using Clara's feeding tube as the problem, your students will use gravity feed bags or milk jugs/pop bottles with holes, to measure unit rates when the bag or jug is at varying heights from the ground.
Students quickly realized as they are compiling the data that the higher the bag or jug is from the ground, the faster the unit rate is.
Students will analyze the data to determine the best height for the bag to be hanging to hit a certain unit rate.
To extend learning, they will determine the validity of the bag measurement markings (quality control specialists) and/or create a schedule for when she should get water throughout the day.
Thank you and I hope you enjoy! Let me know if you see anything you think should be changed.
