Start the Year Safe: Teaching Middle School Lab Safety That Sticks

Every September, I look forward to rolling out hands-on science experiments with my students. But before the goggles go on and the Bunsen burners come out, I know we need to build a strong foundation: lab safety . Let’s be honest, middle schoolers can be equal parts curious and impulsive. They love the idea of “real science,” but sometimes forget that science involves risks if we’re not careful. Over the years, I’ve realized that the way I teach safety at the start of the year makes all the difference in how seriously students take it later on. Why Lab Safety Matters in Middle School I’ve had students ask, “Do we really need to go over this? I already know not to drink the chemicals.” And sure, most of them understand the obvious rules. But what they don’t always think about are the smaller details, like leaving a backpack in the aisle (hello, tripping hazard!), or wearing long sleeves near an open flame. Those little things can lead to big problems if we don’t practice safety consi...

Middle School Science: Making a Model of the Respiratory System using a Pop Bottle and a Balloon

My Grade 8's have been learning about the respiratory system in science.  This week, we made models of the respiratory system using a pop bottle, a balloon, and a plastic shopping bag. I got the idea from Habits from the Heart and created a lab worksheet for my Grade 8's to follow.  I have guided the students through all the labs we've done up until this point, but for this lab, I stepped back and let the kids take the lead.   I told them that I would help if they got stuck, but it was their job to work with their partner to follow the instructions on the handout. Most of the kids followed the instructions very well, but the trickiest part was creating the handle on the bag, and securing the elastic band. Here is one of the finished models: I loved going around to the different tables to see the reactions from the students when they pulled and pushed the diaphragms (plastic bags) of their models and saw the lungs (balloons) inflate and deflate.  T...
