Simple Machines: Using a Spring Scale to Measure N's

 What is an "N"? You might be asking. 

Yes, this is Physics for first and second graders. Here's an example of an Eduflow hybrid learning assignment for our study of simple machines. We began with the inclined plane.

Watch the video SciShow Kids Ramps: A Super, Simple Machine!

Add any new types of inclined planes you discover

into your I Spy mini-notebook!

How Many Newtons? Using a Spring Scale to Measure Force

Build an inclined plane and pull several heavy books up it.

Measure the force using a spring scale!

To give you an idea of how to use a spring scale to measure force,

watch these two videos:

How to Use a Spring Scale to Measure Force

The unit of measurement used for force is called a Newton or N for short.

It is named after Isaac Newton.

How to Set Up this Experiment Notice how the string is attached

to the book on this one.

Remember to pull it as a slow, steady speed when measuring force.

Remember, this is a tool not a toy. Treat it with respect.

Experiment with your inclined plane. Make it shorter. Make it longer.

Use different types of surfaces. Record your findings on your record sheet.

You're thinking like a scientist!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

And so we began both at home and at school....

We learned how to read the spring scale.

We started out with less slope and then increased the slope

and increased the load.

We recorded our findings in our yellow lab notebooks.

Who knew there was so much to be learned

about inclined planes!? We find them everywhere

around us, including in our parking lot!

This is the start of a great study of simple machines!
