# Inclined planes simple machines essay

Lots of hand on activities, book recommendations, free printables, and more! These science activities for kids are recommended for Kindergarten, 1st grade, 2nd grade, 3rd grade, 4th grade, and 5th grade students.

Today we start a new hands on science unit for homeschool kids — simple machines. We will discuss why we need simple machines, simple physics concepts for kids, and discuss the first of the six simple machines — inclined plains. This unit is geared towards Kindergarten, 1st grade, 2nd grade, 3rd grade, 4th grade, and 5th grade students.

Why do we need Simple Machines? We need simple machines to help us work more effectively. To better understand how machines work, we need to define some physics concepts for kids.

Simple Physics Concepts for Kids We started out reading some books the heart of any study. These are our favorites that I highly recommend. This beautifully illustrated picture book explains the basics of forces and motion in an easy to read rhyming book. Put a box of books that is too heavy for your child to lift on the floor.

Ask your child to life the box on the table. No matter how they accomplish it, how long it takes, or who helps it is still the same amount of work. When you were moving the box the force of gravity was working against you; making it heavy to lift.

You used energy to lift the box. When you worked together you each had to use less power to accomplish the same work. Simple machines make work easier Machines make our work easier. Think of how much work it would be to pick up a car to take it to the mechanic if we had to do all the work ourselves.

Luckily we have a machine called a tow truck that makes it easier. What are other types of machines we use? Many machines are complex with lots of moving parts, but ALL complex machines are made from six simple machines: Simple machines have one or no moving parts.

Simple Machine 1 - Inclined Planes An inclined plane is a flat surface with one edge raised higher than the other.

They are useful to help moving heavy items from one level to another easier. They include things like hills, ramps, staircases, and so many more! This book helps kids visualize a whole bunch of inclined planes:Many other things we think of as "simple" machines are combinations of the three basic principles.

For example: A pulley is a wheel, and if you try to hoist a load vertically by pulling the rope at a shallow angle, the rope is an inclined plane. An inclined plane is another simple machine. Inclined planes are also known as ramps. Ramps make a trade off between distance and force.

No matter how steep the ramp, the work is still the same. A winding road on a mountain side is a good example of a ramp. Some simple machines are modified inclined planes. The wedge is one of those machines. One or two inclined planes make up a wedge. Examples of simple machines that may be on a building site include screws, ramps, chisels, nails, saws (inclined planes), hammers and wheelbarrows (levers) and pulleys.

See image 3 All these machines make life easier for builders and construction workers. It is crucial that the machines are simple. The inclined planes, pins, levers, pulleys, locks, winches, racks, and belts of the Nautilus and aerobic machines put earlier stages of .
