Several weeks have passed since I posted about our science guided inquiry activity involving potatoes. Thankfully, the experiment is over and the classroom smells better. Yes, beware of 2 week old potatoes fermenting in the classroom! Stinky aroma aside, we learned some interesting things after completing the experiment. On our Day 7 observation, there wasn't a whole lot to report. A few of the potatoes had begun sprouting tiny buds in a few places on the skin. The students made and recorded their observations. We shared some of our inferences about the water traveling through the inside and skin of the potato and helping new buds to form. The students also recorded predictions about what they might see on Day 14.
Day 14 is when we finally observed some real changes. Here are a few photos of our 2 week old potatoes--
