I found some eye droppers that I had in my cabinet so my first graders got a new center last week: practical living. Even though they are 6-8 year olds some still need fine motor work so, they had a transfer task. I colored the water blue to make it more fun. I presented the center to them showing them how to transfer the water. The first few days went pretty well. However, on Friday, I let two students work together and one kept getting blue water on the other's sleeve. I was not a happy teacher. I had even reviewed the presentation with them after the first time this happened.
I did get a kick out them "discovering" that the water dried up over the weekend.
This week we are going to use the droppers again (with clear water). But I am going to do science explorations with them.
