This is a four station lab focusing on lab safety. I have my students rotate through the stations in groups of 3-4 depending on the class size, and spend 10-15 minutes at each station. I don't usually set a timer, but have them switch when it looks like the majority are ready.
The four stations focus on four different learning styles. The first station has questions to read and discuss with the group. The second station is set up to include a picture showing what not to do in a lab. The third station has a graphic organizer to complete regarding safety symbols. The fourth and final station is set up to show a video/song about lab safety and gives students a chance to summarize what they have seen.
This activity is also part of my "Becoming a Scientist Unit Plan" that is also for sale in my store!
