In building projects or renovations, architects and administrators tend to label the science instructional space as a "science classroom," as opposed to a "science laboratory." What exactly is a science classroom, and what is a science laboratory? According to OSHA's Laboratory Standard (OSHA #29 CFR part 1910.1450), "laboratory" means a facility…

Having students design their own methods regarding data collection during a lab may help them formulate appropriate investigative procedures. The authors use a modified gallery walk to develop science skills. (Contains 3 figures.)

The Crime Scene Labs is a technology-enhanced unit with seven laboratory stations. Probes at many of the stations facilitate students collecting and analyzing their own data (some lessons are adapted from Volz and Sapatka 2000). The labs are designed to build 21st-century skills and model reform-based practices (NRC 1996). The crime scene allows…

Ask students to name the aspects of science class they enjoy most, and working on labs will undoubtedly be mentioned. What often won't be included, however, is writing lab reports. For many students, the process of exploration and data collection is paramount, while the explanation and analysis of findings often takes a backseat. After all, if…

If your lab facilities are going to be replaced or renovated, you should insist that the science instructors be involved in the process from planning to construction. You know what you'll need in a facility, and your input should be sought out by administrators and architects alike. Once construction is complete, changes can be very costly, so…

According to the National Science Education Standards, students should be able to describe an object by its position, direction of motion, and speed (NRC 1996). During a unit on motion, the author decided to use Hot Wheels cars as the object students would describe. The first two activities are used to introduce students to the equipment and the…

CSI: The Experience, a traveling museum exhibit and a companion web adventure, was created through a grant from the National Science Foundation as a potential model for informal learning. The website was designed to enrich and complement the exhibit by modeling the forensic process. Substantive science, real-world lab techniques, and higher-level…

Off-road motorcycle racing and ATV riding. Gardening and fishing. What do these high-adrenaline and slower-paced pastimes have in common? Each requires soil, and the texture of that soil has an effect on all of them. In the inquiry-based lessons described here, students work both in the field or laboratory and in the classroom to collect soil…

This article discusses how real research on Down syndrome, being done in a lab at Indiana University-Purdue University Indianapolis (IUPUI), was incorporated into a laboratory activity for middle school students. The activity asked students to evaluate real evidence from the research laboratory of a GK-12 fellow (a graduate student funded by the…

This is the story of how a typical middle school lab was transformed into an open-ended inquiry experience through a few small, but very powerful, changes. By allowing students to follow their own questions, the classroom filled with enthusiasm and students learned much more about photosynthesis, respiration, and the scientific processes. The…

The haphazard storing and tracking of chemicals in the laboratory is a serious safety issue facing science teachers. To get control of your chemicals, try implementing a "chemical tracking system". A chemical tracking system (CTS) is a database of chemicals used in the laboratory. If implemented correctly, a CTS will reduce purchasing costs,…

Asbestos has been used in the construction of elementary, middle, and high school ceilings, floor tile adhesives, pipe and structural beam insulations, science laboratory benches, wire gauss on ring stands, fume hood panels, general insulation, and more during the 1950s through early 1970s. Why? Primarily asbestos was selected because of its…

This article provides some tried and true methods of avoiding materials management and traffic problems associated with hands-on activities. While each class has its own personality and each teacher has his or her own style, these tips can be useful and practical in a variety of settings.

The feeding of Diarmis proboscis is an exciting outdoor laboratory activity that demonstrates a single concept of adaptations--cryptic colorations. The students are "transformed" into D. proboscis (no Harry Potter magic needed) in order to learn how adaptations work in the natural world. Prior to beginning this activity, students should have a…

Science laboratory activities and classroom demonstrations can be both fun and serious. "Fun" in that the students get nature to expose a few of its secrets in interesting ways. "Serious" in that there needs to be respect for the equipment and materials used in experiments and demonstrations in order to stay out of harm?s way. Laboratory accidents…
