Simple machines

Science

• The child learned about the different types of simple machines, such as levers, pulleys, inclined planes, and wheels and axles.
• They learned how each simple machine makes work easier by reducing the amount of force needed or by changing the direction of the force.
• The child learned about real-life examples of simple machines, like using a lever to lift heavy objects or using a wheel and axle to move things more easily.
• They also learned about the concept of mechanical advantage and how simple machines can provide an advantage in doing work.

For continued development, encourage the child to explore more examples of simple machines in their everyday life. They can look for simple machines at home, at school, or even in the playground. They can also try to make their own simple machines using household materials or building kits.
