Simple Machine 

Here is the booklet you have already started using. Download

Before you start on the booklet you need your own force meter (spring balance is a type of a force meter). You DO NOT need to use standard weights if you don't have them. Use coins or any other object that you think would be useful. Recall our activity to compare the weights of two stones. In fact, do not need to build the EXACT same force meter, you can use this video (go to video) as a start and use your creativity and the trash around you to make your own meter. The second video (go to video) is an example of this type.

Ensure that you have some elder around when you need to use tools that can cause injuries.
You don't want to spoil your holidays with stupid injury, don't you?

Here is the Ted-Ed video lesson I have customized for you all. (Go to Lesson)
Watch the video, Think and answer the questions given. Read and discuss more about the topic of levers.

Explore the website- to get your creative juices flowing to build your machine.
Especially the following two pages: Simple Gears and Law of Moments.
