Designing a Laboratory

We are opening a new academy for grades 10, 11, and 12. We're going to have a science lab for combined use in biology, chemistry, and physics. I've taught in labs, but I've never designed one. Where do we start?
K. D. -- Oklahoma


There's nothing more exciting for a science teacher than walking into a new laboratory. The first thing we notice is the equipment. But there's a lot more to designing a lab than selecting and installing the tables.

Whether you're constructing a new facility or remodeling an existing one, planning the lab facilities is a complicated process. It's better to work out all the details in advance than have to go back and correct any mistakes or omissions. I would strongly recommend that you start with the NSTA Guide to Planning School Science Facilities, available through the NSTA Science Store. This publication has a chapter on safety guidelines (including storage of materials), sample floor plans, Americans with Disabilities Act (ADA) guidelines, and even suggestions for "green" labs. It has user-friendly chapters on the steps of this planning process, lots of photographs, and checklists. It also is essential you research recommendations or requirements from your state department of education and your local building codes.

I assume you are going to meet with all of the science teachers for their input. Ask a lot of questions: What kind of science instruction would take place in the lab: lecture/discussion with supporting lab activities vs. an inquiry-based curriculum with ongoing activities? How many students will be in a class? What kinds of investigative processes are suggested or required in your state's science standards? What will be the role of technology? The NSTA Guide has many discussion-starters.

The first priority should be safety: features such as showers, eyewash stations, fume hoods, air exchangers, fire extinguishers and blankets, sanitizing equipment for goggles, master shut-off switches (for gas, water, electric), adequate and uncluttered workspace dimensions, room size, and unobstructed exits from the lab. The NSTA Guide explores what should be in place so that students and teachers can work safely. The Council of State Science Supervisors also has recommendations in their publication, Science Safety: Making the Connection.

I talked to several other science teachers who suggested:

  • Include more storage space than you think you'll need, especially if the lab is used for more than one subject.
  • If several teachers share the lab, include some adjoining office space for teachers to work and store teaching materials.
  • In addition to the lab stations, get flat-top student desks or tables that can be pushed together for cooperative work.
  • It is impossible to have too many electrical outlets or dataports (if you're not wireless).
  • Include a large wall area for a white board—preferably an interactive one—or at least a
  • Visit other schools to see their facilities. Try to go during the day when students are there.
  • Be sure to budget annually for repairs, upgrades, or replacement items. Include training costs in your budget.
  • Train all science staff in safe laboratory procedures and handling of materials. Revisit safety procedures annually, or more frequently if needed.
  • Include administrators in any discussion of safety issues or other concerns.

  • If anyone has other suggestions for K.D., please feel free to add a comment!

    Conference First-Timer

    I’m very fortunate to be attending NSTA’s National Conference on Science Education this year. I’ve never been to an event of this size, and I want to get the most I can out of it. Do you have any suggestions for a first-timer?
    Renee, Flint, Michigan

    Congratulations! Attending this event is a wonderful professional experience. I assume you’ve registered, made arrangements for lodging and transportation, and have your lesson plans ready.

    There are a few things you should do before you go:
    • Participate in the March 3 NSTA webinar How to Maximize Your NSTA Conference Experience. If you miss it, look for the archived version.
    • Check out the conference blog and the conference event on Facebook. Ask other participants in the blog and Facebook group for advice.
    • Consider what topics you want to focus on at the conference: What content do you want to know more about? What areas are a struggle for your students? Are you looking for new textbooks or equipment? Get suggestions from your colleagues, too. Ask your students what you should learn more about (related to science, of course!). Then go to the conference website and use the Session Browser to look at the session descriptions. You can even print out a personal mini-program.
    • Preview the Transcript section on the conference site. When you turn in a session evaluation, the session will be added automatically to your transcript. You can also add events manually. This is a great way to show your administrators which sessions you attended (and it looks impressive!).
    Some hints on what to take:
    • A rolling bag, if you know you can’t resist picking up every brochure and session material you encounter (resistance can be futile).
    • Address labels are handy for sign-up sheets and marking your program and other materials.
    • If you don’t have any business cards, get some or make your own. Be sure to include your e-mail address and what and where you teach. These are great to handout when you’re networking with other teachers, presenters, and even exhibitors.
    • A digital camera is handy to take pictures of equipment, displays, speakers, and new friends.
    • Have an envelope or other system for keeping receipts and other documents. Expenses not reimbursed by your school might be tax-deductible (check with your accountant).
    • Above all, pack comfortable walking shoes!
    At the Conference:
    • Pick up your badge holder, your copy of the program (there’s one for each day) and other conference materials ahead of time, if possible. Take some time to finalize your daily schedules. I like to put a small reminder in my badge holder with the session names, times, and locations.
    • Attend the first-timers session on the first day.
    • Turn in the session evaluations.
    • Divide and conquer if you’re attending with a friend or colleague. You can only be at one place at a time, so coordinate with other teachers to share notes and materials from sessions missed.
    • Consider taking some snacks and a water bottle (the concessions are often crowded at lunch time).
    • Resist the temptation to collect every brochure, poster, and promotional giveaway in the exhibit area. It’s like a science wonderland! But whatever you collect, you’ll have to get home somehow. I know teachers who take an empty bag (see above under things to take) they can check on the way home (cheaper than shipping via a delivery service).
    • Take some time for sightseeing. There will be a booth at registration staffed by local teachers. They’ll have lots of ideas and suggestions for what to see and do.
    • Keep a log or journal of the sessions you attended, people you met, and new ideas. Update your homepage, Facebook, or class Wiki/blog with a summary of what you are learning at the conference. Update your conference transcript.

    Back Home:
    • Share your experiences with your students. Use some of the promotional items you collected as prizes or gifts.
    • File your notes and handouts. Share the materials and what you learned with your colleagues.
    • Send a note of appreciation to the administrator who approved your attendance at the conference. Write a brief article for the school or district newsletter, if appropriate.
    • Print your transcript.
    • Get ready for next year!
    I know I’m not the only teacher going to the conference. Does anybody else have tips for conference newbies? Please leave a comment.

    Science and Reading

    I have to attend a workshop on teaching reading in the content areas. Is it really the job of a secondary science teacher to teach students how to read?
    —Sofia, Visalia, California


    Short answer—Yes, it is the job of science teachers to help their students learn how to read science materials.

    I once worked on a project that involved reading in the primary grades. I was surprised much of the instruction took place with stories and most of the books in the classroom libraries were fiction as students learn to read. However, in the upper elementary and secondary grades, students read to learn. They are expected to comprehend and learn from nonfiction or informative text (as in textbooks, websites, and other publications). These materials have a different structure and different kinds of illustrations than fictional text. I wonder if many secondary students’ reading “problems” are, in reality, a lack of guidance and experience in interacting with informational text.

    Unlike what students might see in a reading or English class, science resources are not usually written in a story-telling style or in chronological sequence. Science text often starts with a main concept and then provides descriptions or supporting details. Science text often uses headings, subheadings, abstracts, summaries, sidebars, footnotes, and graphics. Science text uses specialized vocabulary and may be written from an expert point of view. Students may not realize reading science text can be a slower process than reading a novel or story, and rereading a section is appropriate and even encouraged.

    It's frustrating for teachers when students don't seem to comprehend what they're reading. Two resources I've used and would highly recommend are Teaching Reading in the Content Areas: If Not Me, Then Who? by Rachel Billmyer and Mary Lee Barton and its companion Teaching Reading in Science (A Supplement to Teaching Reading in the Content Areas) by Barton and Deborah L. Jordan (both are available from the Association for Supervision and Curriculum Development (ASCD) bookstore . These books focus on reading for comprehension and include activities and graphic organizers to engage students before, during, and after reading content area materials.

    Understanding science text also requires visual literacy. Think of the many nonlinguistic representations used in science: symbols on a weather map, the Periodic Table, chemical equations, Punnett squares, molecular diagrams, formulas, graphs, diagrams, and maps. It's important for science teachers to help students understand how these graphics have meaning and are an integral part of the language of science.

    Regardless of the grade level, an effective way to help students interact with text is by modeling with a “think-aloud,” making your thinking and reading processes visible (and audible) to students. For example, science textbooks have many graphics supporting the content, but many students do not always see the relationships between graphics and text. It’s been my experience that taking a little time to model how to make these connections may help students become more independent readers. Some teachers even accompany their students on a "guided tour" of each chapter of the textbook.

    If a secondary student cannot decode words, there is certainly a need for intervention by reading specialists. But helping students develop strategies to comprehend text material is an important job of all content teachers. It's unrealistic to expect our colleagues in the language arts department to teach students how to comprehend science text (and history text and mathematics text) when they have their own curriculum and skills to teach. Many of the reading skills students learn in their other classes can be transferred to science, but they may need some help from us to make the connections.

    If you'd like to see how other science teachers address the issue of reading and science in their classes, go to the NSTA store and enter reading as a search term. You'll get a list of recent NSTA journal articles with a wealth of ideas (journal articles are free to NSTA members). For more information on the "think-aloud" strategy, check out this school district resource and the TeacherVision website.
