Let’s explore simple machines in basic science:
- Lever: 🤸‍♂️
- A lever helps us lift or move things more easily.
- Examples: see-saw, crowbar, and scissors.
- Pulley: 🏗️
- A pulley helps us lift heavy objects by pulling on a rope or chain.
- Example: flagpole, curtains, and crane.
- Wedge: 🔪
- A wedge is like a triangle and helps split or cut things apart.
- Examples: knife, axe, and doorstop.
- Screw: 🔩
- A screw is like a twisty nail and holds things together.
- Examples: screws in furniture and lids on jars.
- Inclined Plane: 🏞️
- An inclined plane is like a ramp and makes it easier to move heavy things up or down.
- Examples: wheelchair ramp, slide, and hill.
- Gear: ⚙️
- Gears help machines work smoothly by turning one gear to make another one move.
- Examples: bicycle gears and clock gears.
- Wheel and Axle: 🚲
- A wheel and axle help us move things easily by spinning around an axle.
- Examples: bicycle wheels, car wheels, and doorknobs.
By understanding these simple machines, we can make our work easier and do fun experiments to learn more about how they work!
