Category Archives: Ice
For the past two weeks, we’ve been experimenting with ice. This is the first unit this year that has been truly all inquiry. Usually, I have to provide some leading questions (ok, MANY leading questions!) to get us around to where we need to be, but this time, it took only three.
What do you know about ice?
What are your experiences with ice?
When do we usually see ice?
We only got the first one answered and went in a completely different direction than what I had planned (at least that’s what I wanted them to think!!). I was expecting to use the other two questions and after 2 weeks now, we still haven’t gotten around to answering them!! Did I mention I LOVE INQUIRY??
Below are some pictures of the things we have been doing. Most of the charts you can probably figure out, but we did two experiments and I wanted to explain them at bit.
Yesterday, after talking about ice and how to get rid of it, we determined that we wanted to test different types of salt. I happened to have (wink, wink) rock salt and table salt in the room along with some ice and cups. We had 5 different types of things to test to determine how best to get rid of ice; the sun (a flashlight), our hands, rock salt, table salt, and a base (the control group). We waited 5 minutes and then measured to see how much water was in each one.
Today, we used dirt, gravel, hot water, and sea salt to try the experiment again. This time we used an ice journal to record our findings. I am presenting at NSTA in Philadelphia in March and this is part of what I will be sharing.
Okay, now on the to the pictures:
