We used this activity in our homeschooling and I’ll be saving it for portfolio purposes (it being so obviously science-ey and all), but it’s also just a fun activity. And good writing practice!

Any child who has ever taken a bath has probably done this experiment on their own, so I wanted to use the familiar concept to introduce the process of testing a hypothesis and interpreting data.
