This column shares safety information for the classroom. STEAM subjects--science, technology, engineering, art, and mathematics--are essential for fostering students' 21st-century skills. STEAM promotes critical-thinking skills, including analysis, assessment, categorization, classification, interpretation, justification, and prediction, and are…

Pet birds, fish, reptiles, and mammals--all are often found in elementary classrooms because of the wide variety of opportunities they provide for exciting teaching and learning experiences. Applications of the opportunities these organisms can provide is reflected in the "NGSS" Life Science progression of disciplinary core ideas,…

Should middle school science teachers be concerned about students bringing in unknown sources of soil to work on in class as the activity suggests? The science is well intended, but is it safe? What are some possible safety issues that might be of concern in dealing with soil samples? This month's column provides several examples of unsuspecting…

The National Science Teachers Association's (NSTA) Science Safety Advisory Board recently launched the Safety in the Science Classroom portal. This portal serves as a gateway to safety resources for teachers, supervisors, and administrators. It also contains an evolving list of safety resources for elementary, middle, and high schools. The list…

All elementary teachers should be aware of their students' allergies especially when they are planning to use plants or animals in the classroom or interacting with them in the field. This knowledge is essential because allergy symptoms can range from an itchy rash to anaphylactic shock. This column shares safety information for the science…

Students coming into science labs need initial and ongoing training about safety standards and best practices. They also need to develop good attitudes about their work and the health and safety of their teachers and fellow students. The "School Chemistry Laboratory Safety Guide" is a resource for science teachers and school administrators to help…

This month's column features two true stories about the use of chemicals in the middle school science classroom. The lesson of these stories is simple. Certainly, it is prudent to have age-appropriate experiences in science, given the developmental constraints of students in middle school. On the other hand, when the curriculum necessitates…

Batteries commonly used in flashlights and other household devices produce hydrogen gas as a product of zinc electrode corrosion. The amount of gas produced is affected by the batteries' design and charge rate. Dangerous levels of hydrogen gas can be released if battery types are mixed, batteries are damaged, batteries are of different ages, or…

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…

When renovations or new construction occur, fire extinguishers sometimes get lost in the mix. Unfortunately, whether to save money or because the fire code is misinterpreted, some schools do not install fire extinguishers in laboratories and other areas of the building. Let's set the record straight! If flammables are present, the fire code…

Chemistry should be fun and exciting, but much preparation and skill are needed by the teacher and students in working with chemicals. Unfortunately, accidents do happen and things can blow up, but these incidents can help be prevented by knowing and following proper safety procedures. Knowing which chemicals are appropriate for the middle level…

As heat sources go, the old standby for elementary and middle school science laboratories has been the centuries old alcohol lamp. Unfortunately, this inexpensive heat producer has been a continuous source of accidents--many of which are relatively serious. Hot plates are emerging as the most popular source of heat for science experiments. The…

Both indoor and outdoor garden plants can cause problems. For example, the foliage of the bird-of-paradise and philodendron plants is toxic. A poinsettia leaf can kill a young child. Outdoor plants such as castor beans are highly dangerous. All parts of the potato and tomato plant are poisonous, except the potato and tomato themselves. Large…

Studying animals in the classroom enables students to develop skills of observation and comparison, a sense of stewardship, and an appreciation for the unity, interrelationships, and complexity of life. This article offers guidelines for working with live animals in the science classroom or laboratory.

Lighting a fluorescent bulb by touching it to the nose of a student who has one hand on an electrostatic generator is an illuminating demonstration of the properties of voltage. It demonstrates that the several hundred thousand volts of electricity passing through the student's body are not dangerous. However, students and teachers need to…
