What you get

What's in Your Sub Lesson

Everything a colleague needs to run your room for a period.

  • Written for a Colleague

    Every activity states its purpose, what students produce, and what on-track work looks like, so a capable professional can run the room without a script.

  • Self-Contained

    The plan runs on what the materials list names. No logins, no files on your desktop, no routines the sub wouldn't know.

  • Printable Student Work

    A worksheet, handout, or exit ticket comes with the plan, so the sub has something to hand out and something to collect.

  • Contingencies Built In

    Options for students who finish early, a paper path if the tech fails, and what to collect and leave behind at the end.

  • Grows Into a Full Sub Day

    One click builds the sub day: every period with its times from your planner, this lesson linked into its slot, and your notes to the sub on one page.

  • Devices or Paper

    Tell it whether students have devices. With devices, the plan adds one device-based segment and its paper fallback; without, it's paper and discussion.

For the Substitute

This is a cumulative review of plate-boundary types and the evidence scientists use to reconstruct past plate motion. Students first refresh prerequisite pattern-reading skills, then analyze several independent data sets and finish with an individual exit ticket. The central expectation is that students explain how evidence supports plate movement rather than only recalling vocabulary.

Before class

  • Find the stacks of the Plate Tectonics Evidence Review Packet and the Plate Tectonics Review Exit Ticket, one of each per student; print them from the lesson materials if they are not with these plans.
  • Find the Plate Tectonics Evidence Reference Sheet, one per pair, and place one between adjacent seats; print if it is not with these plans.
  • Write the time blocks where students can see them: introduction 7 minutes, evidence investigation 25 minutes, boundary review 13 minutes, exit ticket 5 minutes.
  • Arrange students to work with the person next to them; no specialized grouping information is required.
  • Have pencils and a small supply of colored pencils or pens available.

Learning Objectives

  • Identify and compare convergent, divergent, and transform plate boundaries, including the landforms and geologic events associated with each.
  • Analyze fossil, rock, continental-shape, and seafloor data to identify patterns that provide evidence of past plate motion.
  • Construct a claim about past plate motion and support it with relevant evidence and scientific reasoning.

Introduction

Opening the lesson

7 min
Distribute the Plate Tectonics Evidence Review Packet. Students independently complete the four-item prerequisite check, which asks them to identify a pattern in rock or fossil data, interpret a simple map key, match one boundary diagram to its name, and distinguish evidence from an inference. After 4 minutes, students compare answers with a partner for 2 minutes. Briefly review the answers and clarify that scientists cannot directly observe ancient plate positions, so they use multiple matching patterns as evidence. The purpose is to activate map- and pattern-reading skills needed for the investigation. Students should have four attempted responses and corrections in a different color or with a check mark.

Main Activities

1

Evidence Investigation: Reconstructing Past Plate Motion

25 min
Students work with one partner but record individual answers in the collectible packet. The packet provides three compact evidence sets: continental shapes plus fossil and rock distributions, seafloor ages and magnetic-band patterns on opposite sides of a ridge, and boundary features such as trenches, mountain chains, earthquakes, and volcanoes. For each set, students identify two patterns, infer the type or direction of plate motion, and explain how the data support that inference. Partners then complete a claim-evidence-reasoning response answering: What combination of evidence best supports the conclusion that Earth’s plates have moved over time? Allow approximately 7 minutes for each evidence set and 4 minutes for the final response, including partner discussion and transitions. The purpose is to practice grade-level analysis rather than simple vocabulary recall. Each student produces three completed evidence analyses and one short claim-evidence-reasoning paragraph. On-track work names specific data, distinguishes observation from inference, and explains why matching patterns or symmetrical seafloor data indicate motion rather than merely listing facts.
2

Boundary Review and Error Analysis

13 min
Students individually complete the packet’s plate-boundary matrix for divergent, convergent, and transform boundaries. They record relative plate motion, one typical feature or event, and a brief example of evidence that would identify each boundary. They then analyze two fictional student statements, such as the claim that all volcanoes form at divergent boundaries or that matching fossils alone prove continents were always joined, and revise each statement to make it scientifically accurate. Students compare revisions with a partner during the final 3 minutes. The purpose is to connect evidence of past motion with the processes and surface results of plate interactions. Students produce a completed matrix and two corrected explanations. On-track responses accurately distinguish boundary motions, connect subduction to trenches and volcanic arcs, connect spreading to new seafloor, and recognize that a strong conclusion uses multiple independent lines of evidence.
3

Individual Exit Ticket

5 min
Students independently complete and submit a four-item exit ticket: identify a boundary from a short description, interpret a seafloor-age pattern, select the stronger of two evidence-based claims, and write two or three sentences explaining how two different lines of evidence support past plate motion. The purpose is to measure individual understanding after partner-supported review. On-track work uses at least two specific pieces of evidence and links each one to movement. Collect both the packet and exit ticket before dismissal.

Assessment

Students will be assessed by the regular teacher from the collected work. The evidence packet shows whether students identified patterns accurately, interpreted boundary processes correctly, and cited multiple independent data sources in their claim-evidence-reasoning; the exit ticket checks boundary identification, seafloor-data interpretation, evaluation of the stronger claim, and an explanation connecting at least two lines of evidence to past plate motion. Collect both documents and leave a short note on how many were turned in, any misconceptions that came up repeatedly, and any students who left substantial sections incomplete.

If Things Go Differently

If students finish early

  • Check that every inference in the packet cites a specific observation or number from the reference sheet.
  • Add a labeled sketch of one plate boundary and annotate the direction of motion, landform, and likely geologic event.
  • Write a rebuttal to the claim that one matching fossil is sufficient by itself to prove a complete reconstruction of past continents.

Wrapping up

  • Collect every student’s review packet and exit ticket; keep the two items together if possible.
  • Count the collected exit tickets and note any absent students or substantially incomplete work.
  • Leave the collected work in clearly labeled stacks on the teacher’s desk with a brief note identifying common misconceptions or behavior concerns.
  • Collect reusable Evidence Reference Sheets and return desks and supplies to their original arrangement.

Standards

  • MS-ESS2-3: Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions.

How it works

From Topic to Sub Lesson in Four Steps

  1. Tell it what the class should work on

    Enter the topic, pick the subject and grade, set the period length, and say whether students have devices. Add a note about where the class is in the unit if you like.

  2. Review the lesson

    In about a minute the full lesson opens: an overview for the sub, a timed lesson, and what to do if things go differently. The student documents and slides appear on the same page a minute or two later. Read it the way you'd read a plan from a colleague.

  3. Print it

    Print the lesson straight from the page or download it as a PDF or Word doc, then print each student document from its own card.

  4. Keep it for next time

    The lesson and its materials save to your library automatically. From there, one click builds the full sub day: your periods and times from the planner, this lesson in its slot, and one page the sub runs the day from.

FAQ

Sub Lesson Generator Questions

What does the sub lesson generator make?

A complete substitute lesson for the topic you enter: an overview of what the class is working on, a timed lesson with a clear opening, activities, and an assessment the sub collects, a printable student document, and notes covering what to prepare, what to do if students finish early or the tech fails, and how to wrap up. It's the same lesson engine Lesson Maker Pro uses for regular lessons, written for someone who has never met your class.

How long does it take?

About a minute for the lesson. The student materials and slides generate in the background and appear on the lesson page a minute or two later.

Is it free?

Yes. Generating takes a free teacher account, which includes 5 generated lessons a month. Every sub lesson saves to your library so you can reuse it, and Pro removes the cap.

Will a substitute be able to follow it?

It's written for a teaching professional, not read aloud from a card. Each activity says what it's for, what students should produce, and what on-track work looks like, so the sub can make judgment calls. Nothing depends on your routines, your files, or your presence.

Can I add my schedule to it?

Yes, on the sub day document. It lists every period of the day with its times (filled in from your planner), links a lesson into each teaching period, and carries an opening and closing note to the sub on one page. It assumes the sub binder on your desk covers procedures, seating, and who to call, so there is nothing else to fill in. Print the packet or share a private link, and nothing about individual students is stored in the app.

Do students need devices?

No. The default plan is paper and discussion only. If you say students have devices, the plan includes one device-based independent segment and a paper fallback for it. You can also turn the plan into a Digital Experience (one a month on the free plan): a self-paced version students work through on their own devices while you watch the dashboard from home.

Can I edit the plan?

Yes. You can edit the lesson's objectives, activities, materials, and assessment, and any of the generated materials, or regenerate a piece with different instructions. The notes for the substitute are generated with the lesson; regenerate the lesson to change them.
