7th Grade Science Sub Plan — No-Prep Ideas for Substitute Teachers
No-prep science sub plans — reading and research tasks, observation activities, vocabulary review, and science notebook prompts a substitute can facilitate without lab expertise.

Science sub plans should avoid labs entirely — substitute teachers shouldn't handle chemicals, flames, or specimens without specific training. The best science sub plans use the class period for reading, reflection, research, or concept reinforcement.
No-Prep 7th Grade Science Sub Activities
Science Reading and Summary
Materials: Printed science article or textbook passage
Leave a relevant science article (newsela.com has grade-leveled options). Students read, annotate (underline main ideas, circle vocabulary), and write a 3-sentence summary. Collect at the end.
Science Vocabulary Review
Materials: Vocabulary list from current unit, blank paper or notebook
Students choose 10 vocabulary words from the unit. For each: write the definition in their own words, use it in a sentence, and draw a diagram. No dictionary needed if the unit words are familiar.
Scientist Profile Research
Materials: Computers or printed profiles
Leave a list of scientists connected to the current unit. Each student picks one, researches 5 facts, and writes a paragraph about why that person's work mattered. Works even without computers (use printed profiles).
Science Concept Diagram
Materials: Blank paper, colored pencils (optional)
Students create a detailed, labeled diagram of a concept from the current unit — a cell, the water cycle, the solar system, a circuit. Must include labels, arrows, and one explanation sentence per label.
Science Journal Reflection
Materials: Science journals or blank paper
Prompt: 'Explain [concept from current unit] to someone who has never heard of it. What would surprise them? What's the hardest part to understand?' No research needed — just prior knowledge.
Classroom Management Tips for Science Sub Days
- →Explicitly tell students: 'We are not doing a lab today — the classroom teacher has left reading and writing work'
- →Do not allow students near lab equipment — lock or cover it if possible before leaving
- →Science reading tasks work best when students have a clear annotation strategy (circle new words, underline main ideas)
- →Allow students to work with a partner for the diagram or vocabulary tasks — peer talk aids retention
- →Collect all work — even if incomplete, it documents what happened
Before You Leave (Teacher Checklist)
- ☐Pre-print all reading materials — don't assume the sub can manage printing
- ☐Remove or secure any lab equipment that might tempt students
- ☐Write the unit topic and the day's task on the board
- ☐Leave your email in case the sub has a specific question about content
- ☐Prepare a backup activity in case the primary task runs short
What to Include in Your Sub Notes
- ✓Note the current unit topic so the sub can answer 'what are we studying?'
- ✓Leave any reading materials pre-printed — don't rely on the sub to operate printers
- ✓Specify: no lab equipment to be used under any circumstances
- ✓Note where science journals or notebooks are stored
- ✓List students who need support for reading tasks (simplified text, partner work)
Common Science Sub Day Challenges — and How to Prevent Them
“Students say they don't understand the science reading.”
Leave reading materials with pre-highlighted key passages or a glossary of difficult terms at the bottom. The sub can direct students: 'Try re-reading the highlighted sections first.'
“Students want to do a lab instead of the assigned work.”
Include a clear note on the sub plan: 'Labs require the classroom teacher. Today's tasks are the assigned work.' The sub should refer students back to the work.
Sub Plan Tips: Science in 7th Grade
- 1The safest science sub plan: a science reading article + a vocabulary activity + a diagram prompt
- 2Never leave a lab as the sub plan — the liability and safety risk are not worth it
- 3Leave a scientist of the day fact on the board — it sparks curiosity and gives the sub an easy conversation starter
Frequently Asked Questions
Can a substitute run a science lab?
Generally no — labs involve safety protocols, student behavior management with equipment, and content knowledge that substitute teachers typically don't have. Leave reading and writing tasks instead.
What science sub plan works for any grade?
A science reading passage with comprehension questions + a vocabulary activity + a concept diagram prompt. These three activities require no content expertise from the sub and keep students meaningfully engaged.
What if students have a science test scheduled on the sub day?
Consider moving the test if possible — test administration requires the teacher's judgment about accommodations, timing, and questions. If it must happen, leave extremely detailed instructions about materials, timing, and collection.
