## ✔ PART 1: MATCH THE SIMPLE MACHINE TO ITS OPERATION

Correct Matches:

1. lever →
> *a straight rod or board that pivots on a point called a fulcrum which can be moved depending weight of the object and the force needed; used to make lifting easier.*
👉 Explanation: A lever uses a fulcrum to multiply force. Examples: seesaw, crowbar, bottle opener.

2. wheel & axle →
> *a set of wheels connected by a smaller cylinder, called an axle, allowing the set to turn; makes moving objects easier.*
👉 Explanation: The wheel rotates around the axle, reducing friction and making transport or rotation easier. Examples: doorknob, car wheel, skateboard wheel.

3. wedge →
> *two inclined planes joined back to back that fit into crevices and are used to split things in two.*
👉 Explanation: A wedge is essentially two inclined planes back-to-back — it concentrates force to cut or split. Examples: knife, axe, doorstop.

4. inclined plane →
> *a sloping surface, used to alter the effort and distance involved in doing work, such as lifting loads.*
👉 Explanation: An inclined plane reduces the force needed to lift something by increasing the distance over which the force is applied. Examples: ramp, slide, staircase.

5. pulley →
> *a wheel with a groove around the outside edge where a rope is placed and is used to make pulling objects upward easier.*
👉 Explanation: Pulleys change the direction of force and can multiply it (especially with multiple pulleys). Examples: flagpole, window blinds, crane.

6. screw →
> *an inclined plane wrapped around a cylinder which easily moves through material such as wood.*
👉 Explanation: A screw is an inclined plane coiled around a shaft — it converts rotational force into linear motion. Examples: jar lid, bolt, spiral staircase.

## ✔ PART 2: CLASSROOM EXAMPLES OF EACH SIMPLE MACHINE

*(These are common, observable examples in most classrooms)*

| Simple Machine | Example in Classroom |
|----------------|----------------------|
| lever | Scissors, stapler, seesaw (if available), crowbar (in tool kit) |
| wheel & axle | Door knob, rolling chair wheels, pencil sharpener handle |
| wedge | Knife (in science kit), doorstop, scissors (blades act as wedges) |
| inclined plane | Ramp (if accessible), stairs, slide (playground nearby), bookshelf ramp for books |
| pulley | Window blinds, flagpole (if school has one), science demo pulley system |
| screw | Jar lid on supply container, bolts holding furniture, pencil sharpener screw mechanism |

> 💡 Note: Some tools combine simple machines — e.g., scissors use both levers and wedges. For this activity, focus on the primary function or most obvious machine type.
