The 7th graders at White Hill build a water timer with a plastic bottle, tin foil, and a rubber band. The worked on 1 minute timers, 2 minute timers, and 4 minute timers.

This was a very successful lesson. The students were super engaged and worked hard to determine how to make a one, two, and "free choice" minute timer. In the end, we plotted all of the class data on one plot. For many, it was their first introduction to a scatter plot. Nice to bring in statistics in such a natural way. We were able to come up with a "best fit" line that showed that there is indeed a proportional relationship between the amount of water and the length of the timer. A next step would be to look at how the rate at which the water comes out changes in relationship to the depth of the water. One way to demonstrate this is to take a 1 quart plastic milk jug and make 5 or 6 holes up the side. Tape the holes over and then fill with water. When you remove the tape you can quickly see that the hole at the bottom creates a stream that reaches out much further than the hole on the top.

This looks like a great lesson! I like how you had the students build the 1 minute and 2 minute timers and then do a "free choice" timer. I did a similar activity with measurement. The students were really engaged. Thanks for sharing!

I would like to try this with my 5th graders. They were given a rate/distance conversion problem last week that they were having trouble visualizing and frankly just understanding the relationship between rate and distance(measurement). This lesson seems like it would be valuable for them to actually "see" rate and measurement by literally manipulating the time and the measurement. Thanks for the post!
