Science 8 I gave these graphics to the students and had them make observations. I didn’t know it at the time, but the work that we put in at the beginning of the year with observations is really paying off. I was able to randomly go around the room and get good responses from almost all of the students. The diffusion example was recognized as being very similar to our food colouring lab, and the kids were able to see how osmosis was different (sugar particles couldn’t go through the membrane but the water could). The class still has to work through the specifics, especially in terms of concentration. I think next class I will use some Peer Instruction for formative assessment and checking for understanding.
