Graphing: Growing Monkey

Look around your favorite retailer for these Growing "Things". I've seen turtles, crocodiles, princesses, pirates, etc.

We happened to have a monkey (thanks Aunt Amy - I told you it would show up on here!).

Take some measurements of your "thing" before you do anything with it.

Then place it in water.

Most of these say they'll take up to 72 hours (that's 3 days) to reach full size. I recommend you start on Monday, so you'll have all week to watch it.

Each day, at the same time (or as close as you can come), retake the same measurements you took initially.

At the end of the week, you should have several data points that can be graphed. Older students could determine the rate of growth.

You may even want to have them look at the data after 24 and 48 hours and ask them to predict how large it will grow by 72 hours.

My apologies, my "after" pictures of your monkey didn't turn out, so I don't have much for you. Our monkey about doubled in size. Some of the "things" out there are a lot smaller to start with and claim to increase by 600%, which should give you some great measurements.
