I started my first full-time teaching position this semester—high school biology. According to the students, they did not do many labs last semester. I’m eager to do inquiry activities with my students, and obviously I want to do so safely. The department chair gave me copies of the safety contracts and handouts to use. Do you have any other suggestions as to what I should consider before our first lab activity?

Congratulations on your new job! I’m sure your students will learn from and enjoy the lab investigations and activities. I would recommend investing in a copy of the NSTA Press book Investigating Safely, which has many suggestions and resources for high school science.
It’s hard to take over in the middle of the year, so before you do your first activity, take time for an “inspection:”
Before your first activity, do an orientation with your classes, reviewing safety issues and your routines. Show them where the safety equipment is, and demonstrate how/why/when to use it. Create your lab groups ahead of time. Your first activity should be one that does not require a lot of materials and that does not have many safety issues. During this “dry run” with full classes, circulate around the room and take notes. Remove anything blocking student access to the lab stations or exits, such as extra desks, extension cords, or carts. Decide where students should stow their backpacks, coats, and other personal gear. Stand at each lab table to determine if students can see the board or screen. Look for any corners where you can’t see the students. Adjust your plans and routines, if necessary, based on this assessment.
It is a challenge to engage students in planned and purposeful science investigations that are also interesting and relevant to them. Safety concerns can seem overwhelming, but planning (and over-planning), awareness, and common sense will see you through.
