Technology Lesson Topic & Standards

In groups of 5, the 7th grade student will work cooperatively with his/her partners to design an experiment to model a leaky faucet within 15 minutes using the given materials and guideline, and determine the amount of water wasted due to the leak over the 30 minutes period. Then, the student will graph the data on a graphing calculator (TI-83/84), and write an equation for a line of best fit and make predictions for different lengths of time based on the data on a blank sheet of paper (Note: Turn in one paper per group).
