5 day-plan(s) · WeLearn JA SCI T2 G4
Day 1: What Are Simple Machines
Grade 4 Science · Term 2, Week 3 · 60 minutes
| Objectives | Recognise simple machines that make work easier. |
|---|
| Materials | Everyday machine pictures |
|---|
| Key vocabulary | simple machine, work, easier, effort, load |
|---|
| Engage (starter) | "How do tools make hard jobs easier?" |
|---|
| Develop (main) | Interactive: match everyday tools to jobs they make easier; introduce effort and load; tap-to-reveal simple machines. |
|---|
| Plenary (close) | What do simple machines do for us? |
|---|
| Assessment | Recognises simple machines. |
|---|
| Teacher notes | The MoEY step-up: simple machines this year. |
|---|
Day 2: Levers
Grade 4 Science · Term 2, Week 3 · 60 minutes
| Objectives | Investigate how levers make work easier. |
|---|
| Materials | Ruler, pivot, weights |
|---|
| Key vocabulary | lever, pivot, fulcrum, effort, load |
|---|
| Engage (starter) | "How can a lever lift a heavy load with a small push?" |
|---|
| Develop (main) | Interactive: build a ruler lever over a pivot; lift loads with different effort positions; tap-to-reveal how levers help. |
|---|
| Plenary (close) | What is the pivot of a lever called? |
|---|
| Assessment | Investigates levers. |
|---|
| Teacher notes | Effort further from the pivot lifts more easily. |
|---|
Day 3: Inclined Planes
Grade 4 Science · Term 2, Week 3 · 60 minutes
| Objectives | Investigate how a ramp makes lifting easier. |
|---|
| Materials | Ramps at angles, cart, force meter |
|---|
| Key vocabulary | inclined plane, ramp, slope, effort |
|---|
| Engage (starter) | "Why do we use a ramp to load heavy things?" |
|---|
| Develop (main) | Interactive: measure the force to pull a load up ramps of different slopes; compare with lifting straight up; tap-to-reveal. |
|---|
| Plenary (close) | How does a ramp help us? |
|---|
| Assessment | Investigates inclined planes. |
|---|
| Teacher notes | A gentler slope needs less effort. |
|---|
Day 4: Pulleys
Grade 4 Science · Term 2, Week 3 · 60 minutes
| Objectives | Investigate how pulleys help lift loads. |
|---|
| Materials | Pulley, string, weights |
|---|
| Key vocabulary | pulley, lift, direction, effort, load |
|---|
| Engage (starter) | "How does a pulley help lift a flag up a pole?" |
|---|
| Develop (main) | Interactive: use a single pulley to lift a load; note it changes the direction of effort; tap-to-reveal how pulleys help. |
|---|
| Plenary (close) | What does a pulley change about lifting? |
|---|
| Assessment | Investigates pulleys. |
|---|
| Teacher notes | A single pulley changes effort direction. |
|---|
Day 5: Review: Simple Machines (Levers, Ramps, Pulleys)
Grade 4 Science · Term 2, Week 3 · 60 minutes
| Objectives | Consolidate levers, inclined planes, and pulleys. |
|---|
| Materials | Machine kits, review stations |
|---|
| Key vocabulary | review, lever, ramp, pulley |
|---|
| Engage (starter) | "Machine engineer challenge!" |
|---|
| Develop (main) | Interactive: build and test levers, ramps, and pulleys at review stations. |
|---|
| Plenary (close) | Name a simple machine and how it helps. |
|---|
| Assessment | Station accuracy. |
|---|
| Teacher notes | Reinforce machines make work easier. |
