My Honors students are exceptionally open-minded. I decided to do away with traditional notes for the Gas Laws unit and let them tell me what they know about the properties of gases. We spent about half of the block breaking through all the misconceptions they had about their world and it led to great discussions in both classes. Then we learned about the relationship between Pressure and Volume using pressure sensors and a syringe. They quickly understood the inverse relationship between the two properties and I was very satisfied with the lesson.
I planned on using the Gas Properties simulation from PHeT just to verify what they had discovered earlier using the pressure sensor. The sim was projected onto the board and I asked for a volunteer to go up and manipulate it. The student quickly figured out how to add gas and I asked the students to explain what they were seeing. The shouted out things like:
- The molecules are constantly moving
- They spread out to fill the container
- They are all moving with the same speed
And while this is going on, the student at the board is playing with the simulation. She is moving the little man to change the volume and pumping in more gas. Well, that's the point where I was no longer needed in the room. The class began to yell out things they wanted her to do: raise the heat, lower the heat, pump in heavier things, blow the lid off, add tons of gravity. I had planned to use the simulation as the next class' lesson, but the students were so into what they were learning that I literally couldn't stop them. I tried to do it. TWICE. But I was completely ignored.
I sat down at a desk and snapped these pictures.
Naturally others wanted a turn so we needed to rotate. I made whomever went to the board make a statement for the class to add to their notes on the topic. No PowerPoint, no outlines, no formal notes. In one block we covered an entire unit's worth of material. And the best part, every word is theirs. I told them nothing.
I am a really lucky teacher to work in a school that has amazing students that let me do the crazy things that I do.
