Risk assessment and safety controls worksheets for Grade 7 Science teach students how to recognize hazards, evaluate risk, and choose appropriate controls during laboratory and field investigations. Designed around Ontario Science STEM Skills and Connections, this resource connects safety decision-making with scientific responsibility, documentation, and ethical work practices.

Recognize Hazards and Evaluate Risk

Students first distinguish a hazard from a risk. They examine hazards such as sharp tools, hot surfaces, electricity, and chemicals that may irritate skin or eyes, then consider risk by evaluating both the likelihood of harm and the severity of possible injury. This gives students a practical framework for thinking about safety before an activity begins.

The resource introduces engineering controls and administrative controls through realistic science situations. Students consider how guards and ventilation can change equipment or the working environment, while training, rules, time limits, eye protection, and labeled chemical containers rely on procedures and human behavior to reduce danger. Safety data sheet information is also addressed as an important source for making safer choices.

Apply Safety Thinking to Lab and Fieldwork

Emergency planning extends the safety discussion beyond identifying hazards. Students work with scenarios involving chemical warnings, fumes, spills, demonstrations, and fieldwork near water. They consider route planning, changing weather conditions, emergency procedures, visible signage, and incident reporting, including situations where nobody is injured.

Ethical responsibilities are integrated throughout the material. Students examine why science workers should follow instructions, protect themselves and others, report incidents honestly, and stop work when conditions become unsafe. These ideas help connect laboratory safety with responsible scientific decision-making rather than treating safety as a separate checklist.

Practice, Review, and Teacher Support

Students apply the concepts through a reading passage, multiple-choice questions, true-or-false statements, concise written responses, matching, a cloze passage, and a Did You Know section. Tasks ask learners to identify hazards and risks, distinguish control types, interpret safety situations, and explain appropriate responses to changing conditions.
