This simple machines grade 5 lesson plan gives you a complete 60-minute investigation your students can do with everyday classroom objects. It aligns with the Ontario Science and Technology curriculum, Grade 5, Structures and Mechanisms strand, and works well across other provincial curricula that address forces, motion, and mechanical systems.

Lesson Overview: Simple Machines Grade 5

Students identify, classify, and test all six simple machines using objects found around the school. Through hands-on stations and a recording sheet, they connect the abstract concept of mechanical advantage to real tools they already use. The lesson closes with a class discussion on how simple machines reduce the effort needed to do work.

  • Grade: 5
  • Subject: Science
  • Duration: 60 minutes
  • Curriculum alignment: Ontario Science and Technology, Grade 5, Structures and Mechanisms strand (2022)
  • Cross-curricular connections: Math (measurement, ratio), Language (science vocabulary, written explanation)

Learning Goal

Students will be able to identify the six simple machines, explain how each one changes the direction or magnitude of a force, and provide real-world examples of each machine found in Canada’s homes, workplaces, and natural environments.

Success Criteria

  • I can name and describe each of the six simple machines.
  • I can explain how a simple machine makes a task easier by changing force or direction.
  • I can match everyday objects to the correct simple machine category.
  • I can record and communicate my observations using labelled diagrams and sentences.

Materials

  • A wooden ruler and a stack of books (lever demonstration)
  • A pencil sharpener or toy car with axle (wheel and axle)
  • A simple pulley system or a rope looped over a hook (pulley)
  • A ramp made from a stiff piece of cardboard and a stack of textbooks (inclined plane)
  • A plastic knife, a door stopper, or a zipper pull (wedge)
  • A jar lid, a bolt, or a corkscrew (screw)
  • Printed station cards (one per station, with guiding questions)
  • Simple Machines Investigation recording sheets (one per student)
  • Spring scale or rubber band for measuring effort (optional but recommended)
  • Pencils, rulers, and coloured pencils for diagrams

Hook (5 Minutes)

Place a heavy textbook on one side of the room and ask two volunteers to slide it to the other side using only their hands. Then place a round pencil case under the book and ask them to try again. Ask the class: “What changed? Why was it easier the second time?” Record student ideas on the board without correcting them yet.

Tell students that today they are going to investigate six types of tools that humans have used for thousands of years to make work easier. Show a short image slideshow (or draw quick sketches) of a construction crane, a wheelchair ramp, a pair of scissors, a screw, and a bicycle wheel. Ask: “What do all of these have in common?” This forces and motion lesson builds from curiosity, not from definitions.

Direct Instruction (10 Minutes)

Using a whiteboard or projected slides, introduce each of the six simple machines with a clear definition, a labelled diagram, and one Canadian example. Keep each explanation to two sentences maximum before moving to the next.

  1. Lever: A rigid bar that pivots on a fulcrum. Example: a seesaw at a Canadian playground.
  2. Wheel and axle: A wheel attached to a smaller cylinder that rotates together. Example: a bicycle or a door knob.
  3. Pulley: A grooved wheel with a rope or cable that changes the direction or effort of a force. Example: a flagpole at a Canadian school.
  4. Inclined plane: A flat surface set at an angle to reduce the effort needed to raise an object. Example: a loading dock ramp at a Canadian warehouse.
  5. Wedge: Two inclined planes joined at one end to split or hold materials. Example: an axe head used in logging.
  6. Screw: An inclined plane wrapped around a cylinder. Example: a jar lid or a wood screw.

After each definition, ask a quick thumbs-up or thumbs-down check for understanding before moving on. This keeps the direct instruction portion tight so students spend more time investigating than listening.

Guided Practice: Station Investigation (25 Minutes)

Set up six stations around the classroom, one for each simple machine. Each station has the physical object, a station card with two or three guiding questions, and space for students to test the machine. Students work in pairs, rotating every four minutes on your signal.

Guiding questions at each station follow this format: “What type of simple machine is this? How does it change force or direction? Where have you seen this machine in real life?” Students record answers and sketch a labelled diagram on their investigation sheet. Circulate to prompt deeper thinking with questions like “What happens if you move the fulcrum closer to the load?” on the lever pulley wheel and axle stations.

For the inclined plane lesson station, students use a spring scale to measure the force needed to pull a book up the ramp versus lifting it straight up. This gives a concrete, measurable experience of mechanical advantage. Find a printable recording sheet template and other science teaching resources to support this activity.

Independent Practice (10 Minutes)

Students complete the back of their investigation sheet independently. They are given a list of ten everyday objects (scissors, flagpole, wheelchair ramp, bicycle, axe, jar lid, stapler, wheelbarrow, zipper, wedge doorstop) and must sort each one into the correct simple machine category. They also write two sentences explaining how one machine of their choice reduces the effort needed for a task.

This activity works well as a formative check. You can browse additional ready-to-use lesson activities to extend or vary the independent task.

Consolidation (10 Minutes)

Bring the class together. Ask one pair from each station to share their most interesting finding. Guide the discussion toward the big idea: simple machines do not reduce the amount of work done, they change how the force is applied, making the task feel easier or more manageable. Revisit the hook activity and ask students to name which simple machine was demonstrated with the pencil case rolling under the book (wheel and axle).

Exit ticket: students write one sentence in their science notebook answering “How does a simple machine make work easier?” Collect these as a quick formative assessment before the next class.

Differentiation

Students Who Need More Support

Provide a visual anchor chart at each station showing the machine name, a picture, and a one-line definition. Pair these students with a peer who can read the station card aloud. Reduce the independent sort to five objects rather than ten, and allow oral responses recorded by a partner or educational assistant.

Students Ready for Extension

Challenge extension students to identify which simple machines are combined in a compound machine like scissors (wedge plus lever) or a bicycle (wheel and axle plus pulley). Ask them to design a compound machine on paper that solves a real problem, such as helping a younger student carry a heavy backpack up stairs.

Multilingual Learners

Pre-teach the six machine names with picture cards before the lesson begins. Allow students to label diagrams in their home language alongside English. Pair them with a bilingual peer if possible, and accept diagrams with minimal labelling as evidence of understanding during the station rotation. The provincial curriculum links page includes resources available in multiple languages for several provinces.

Assessment

  • Formative: Observation during station rotation using a class checklist; exit ticket sentence collected at the end of class.
  • Formative: Investigation recording sheet reviewed for accuracy of diagrams and sorting task.
  • Summative (follow-up): A short written or oral task where students explain one simple machine of their choice, describe its mechanical advantage, and give two real-world Canadian examples.

For a simple rating scale you can adapt for this lesson, try the 5-point assessment rating tool available in the tools section.

Follow-up Lessons

  • Lesson 2: Compound machines, focusing on how two or more simple machines work together in tools like scissors, can openers, and bicycles.
  • Lesson 3: Design challenge, where student teams build a device using at least two simple machines to move a small object across a distance with minimal effort.
  • Lesson 4: Simple machines in Canadian industries, connecting the science content to real careers in construction, farming, forestry, and manufacturing across the country.

Frequently Asked Questions: Simple Machines Grade 5

What are the six simple machines?

The six simple machines are the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw. Each one changes the direction or magnitude of a force to make a task easier. All more complex machines, called compound machines, are combinations of two or more of these six types.

How do you teach simple machines?

The most effective approach to a simple machines lesson combines direct instruction with hands-on investigation. Introduce each machine with a clear definition and a familiar Canadian example, then let students explore physical objects at stations and sort everyday items into categories. Connecting abstract definitions to objects students already use builds lasting understanding and supports Ontario’s inquiry-based science approach.

What is a Grade 5 science lesson?

A Grade 5 science lesson in Canada typically follows provincial curriculum expectations and runs between 45 and 60 minutes. In Ontario, Grade 5 science covers four strands: Life Systems, Matter and Energy, Structures and Mechanisms, and Earth and Space Systems. Lessons are designed to build scientific thinking skills alongside content knowledge, using observation, prediction, investigation, and communication.

How do simple machines make work easier?

Simple machines make work easier by changing the amount, direction, or speed of a force needed to complete a task. For example, a ramp (inclined plane) lets you use less force to raise an object by spreading the effort over a longer distance. A pulley changes the direction of force so you can pull down instead of lifting up, which often feels more manageable. The total work done remains the same, but the machine makes it more practical for a person to accomplish.
