Topic: Inclined Plane

An inclined plane is a slope or a ramp or any slanting surface that helps to carry loads with less effort.

​Essential Question

How has inclined plane changed the world?

​Learning Objective

Analyze and explain how inclined planes make it easier to lift things up.

Sub skill	I CAN	I CAN	I CAN
Analyze and explain	Analyze the data and form the conclusion with the help of the questions provided.	Analyze the data, plot the graph and form the conclusion with the help of given picture.	Analyze the picture provided independently and form conclusion. Give examples from real life where inclined planes are used for purposes other than lifting things up.

Success Criteria

Compare lifting the rock with the inclined plane and lifting it without the inclined plane.

​Extended Learning- CCL

​Mechanical Advantage (MA) is a measure of how much easier a machine (like an inclined plane) makes doing work. For an inclined plane, it’s calculated using the formula: Mechanical Advantage = Length of the Incline/Height of the Incline
Example: Imagine you're helping your friend move a heavy box into a truck. Instead of lifting it straight up, you use a ramp (inclined plane) to push the box into the truck. The ramp makes the job easier. Real-Life Question: You have a ramp that is 6 meters long and the truck is 2 meters high. What is the mechanical advantage of using the ramp?
