A curiosity table. That’s what I call it. Whenever my students have a free minute (which rarely happens), I encourage them to investigate the materials on the curiosity table in our classroom.
Today I added something new—an Atmospheric Mat .
It was a gift from my good friends at Educational Innovations. This unusual and uniquely shaped article elicited intense curiosity from my students. They wanted to know what it was, how to make it work, what you could use it for, and what was the science behind it. “Figure it out,” I told them.
As I watched them explore and experiment, I realized this mat was much more than something to elicit my students’ curiosity. It was a way to teach them what scientists do.
Students first keyed in on the fact that the texture of the surface mattered. They decided to try to lift a desk. The surfaces of our desks are very smooth; we use them as whiteboards. They could lift the desk a little, but not very far.
Deciding that it was because of the smoothness of the surface (as opposed to the weight of the desk), they decided to try something a bit rougher. Success. A rougher surface seemed to work better. The fact that the second object was lighter was not obvious to them.
Next, they decided to try the hallway floor, given that it is concrete and supposedly rougher. Obviously, they were not trying to lift the floor, but rather to see how hard they needed to pull on the mat before it came loose. The floors in our hallway are sealed, which makes them relatively smooth. This meant that the floor in the hallway did not give much more information about how the Atmospheric Mat worked.
To get back into the room from the hallway, students needed open the door. Why not see whether the Atmospheric Mat had the ability to open the door? This trial was followed by hoots and yells as the door opened.
This prompted a huge influx of questioning. Students tested the mat on the wall. They tested it on the board. They tested on their iPads (which did not work, because the iPads are too small). Would they reach a point where the surface was too rough?
Each test gave additional data which led to additional questions about how and why the Atmospheric Mat works. They even tried using it upside down, expecting that it would behave like a suction cup.
As you can see, this is an incredible tool to study forces and atmospheric pressure… and more. At some point, I’ll bring up the fact that there are no “sucking” forces in science. We’ll figure out together that the roughness of the surface isn’t what makes it hard to pull off an object. That’s it’s atmospheric pressure. But for now, the Atmospheric Mat is a tool that I’m going to continue using to ignite my students’ curiosity. I’m going to let my students explore it for as long as they want. Their exploration won’t be driven by me; their curiosity will be what drives them.
At the end of the day, when it was time to stack our chairs, one of my students asked me if she could use the Atmospheric Mat to lift her chair onto the top of the pile. “Give it a try,” I said. She was delighted when it worked and worked very well.
“Hey, Mrs. Foote,” she said after the chairs were stacked, “I feel like a scientist today.”
“You are!” I told her. And it was all due to the Atmosphere Mat that I put on the curiosity table.
