Instructional Management and Safety in Elementary

Science instruction can be highly engaging for young learners. Through investigations and engineering design experiences, students ask questions, define problems, develop and use models, plan and conduct investigations, analyze and interpret data, apply mathematics and computational thinking, construct explanations, design solutions, engage in evidence-based argumentation, and communicate information. These active learning experiences support student understanding and should be planned with careful attention to safety, supervision, and developmental appropriateness.

Student engagement is often strongest when each student has a meaningful role or task. Teachers should ensure that all student activities are appropriately supervised by an adult and that students understand the safety expectations associated with their assigned roles. Any student-designed investigation or engineering design activity must be reviewed and approved by the teacher or instructor before work begins.

Communication about safety should involve the school, the student, and the family. Schools are encouraged to provide a science safety acknowledgment form for students and parents or guardians to review and discuss together. Such forms can help clarify expectations for safe participation in science activities and reinforce shared responsibility for maintaining a safe learning environment. Examples of such forms can be found on the National Science Teaching Association website or in appendix A. However, signed safety acknowledgment forms alone are not enough; educators must provide explicit instruction in safety expectations, and students must demonstrate success with safety training.

Materials management and housekeeping are essential components of safe elementary science instruction. Teachers should provide clear directions for obtaining, distributing, using, returning, cleaning, and disposing of materials. Science materials, equipment, and supplies should be secured when not in use to prevent unsupervised student access. Because preparation and cleanup can be challenging in elementary settings, grade-level teams should collaborate when possible to plan for materials organization, storage, setup, and cleanup. Instructional time must include explicit teaching of safe practices, proper cleanup procedures, handwashing, and emergency procedures.

Science activities require adequate space and sufficient instructional time. Learning environments should allow students to work safely, move appropriately, access materials, and clean up their work areas without crowding. When science instruction occurs in a multi-use classroom; laboratory; science, technology, engineering, and mathematics (STEM) lab; makerspace; or other specialized setting, schools should consider applicable safety recommendations, occupancy requirements, and local facility standards. Activities should be scheduled to allow enough time for setup, instruction, investigation, cleanup, and safe transition between tasks.

STEM labs, makerspaces, and similar elementary learning spaces present additional safety considerations. These environments may support a wide range of activities, including designing, building, testing, data collection, and analysis. Because these activities may involve different tools, materials, processes, and hazards, each learning experience should be reviewed for appropriate supervision, equipment use, personal protective equipment, storage, traffic flow, emergency access, and cleanup procedures.

Schools should provide adequate, secure storage for science materials, equipment, and chemicals. Storage areas should be organized, labeled, and designed to accommodate materials of varied sizes, shapes, and hazard classifications. Flexible shelving, drawers, cabinets, and other storage systems should be used as appropriate to support safe access by authorized staff and to prevent unauthorized student access.

Teacher demonstrations may be used to introduce or illustrate scientific phenomena. Demonstrations require the same level of safety planning as student investigations, including hazard analysis, risk assessment, identification of safety actions, and rehearsal before presentation. When a demonstration has any potential to expose students or observers to injury, appropriate protective measures should be used, such as safety goggles, shields, distance, and other controls. Demonstrations should have a clear instructional purpose and measurable learning outcome. Demonstrations conducted primarily for entertainment are not appropriate for the school setting and may introduce unnecessary risk.
