How to Succeed Teaching Science as a Substitute

Substitute teaching science can feel intimidating if it's not your specialty. The good news: most classes have lesson plans, and your primary job is facilitation — not expert delivery. The substitutes who get called back repeatedly are the ones who establish calm quickly, keep students engaged using proven moves, and leave the room better than they found it. These are learnable skills.

Key Classroom Strategies

1

Emphasize the scientific method as a framework students already know

2

Use demonstrations rather than full lab activities unless the lesson plan specifically calls for them

3

Connect topics to students' everyday experiences (weather, food, technology)

4

Have students predict outcomes before revealing answers to build engagement

5

Keep safety as the top priority and don't run labs you're uncomfortable supervising

Lesson Plan Tips

  • +Review lab safety rules before any hands-on activity, even simple ones
  • +Check with a neighboring science teacher if you're unsure about equipment or materials
  • +If a lab is planned, read through the entire procedure before class starts
  • +Have students write observations in complete sentences to keep them focused
  • +Use the textbook's chapter review questions if you need to fill time

Common Challenges

Lab activities requiring equipment or chemicals you're unfamiliar with

Students wanting to conduct unauthorized experiments

Complex topics where your own content knowledge may be limited

Managing safety with students who don't take lab rules seriously

Emergency Lesson Ideas for Science

No lesson plan? No problem. Keep these ready in your substitute teacher toolkit:

Science myth vs. fact quiz where students discuss and defend their answers in groups

Have students design an experiment to answer a question they choose (on paper, not live)

Nature observation journals using the schoolyard or window views

Watch a short science video and have students write three things they learned and one question they still have

Classification activity where students sort everyday objects by scientific properties
