Newton's First Law of Motion

Salamander's science text book talks about motion, position, friction, but nothing about Newton. So I thought I could introduce Newton and his three laws of Motion and just focus on the first  Law of Inertia, by doing a fun "Turkey Egg Experiment.

I show them a short video on Intertia.

What is Physics? The science of how and why things ________.

Newton was a _____________ who lived from _____ to _______.

He discovered ______ laws of motion.

The first law is called the Law of _______.

The first law of motion says: 'Things want to keep on doing what they are already doing'. If things are at ______, they want to stay at rest, if things are ________ they want to stay moving.

 Or

All the things in this world are lazy, they want to remain in the state where they are unless some outside _____ is applied upon them. This laziness is called inertia.

                                        Or

Things want to stay what they are already doing. They don’t want to move. This is called _________.

Turkey Egg Drop Experiment

Get the egg into the water.

Materials:

Egg, cardboard tube, water, drinking cups, tray, pie pans

Experiment:

1.    Fill the cups with ¾ full with __________.

2.   Center a _______  ________ on top of the  cup.

3.   Place the cardboard __________ on the pie plate, positioning it directly ________ the water.

4.    Now ________ the edge of the pie pan horizontally. Don’t swing up or down!

Thinking:

What did you think of the experiment? How does this show motion?

Answer: The egg it wants to do what its doing - not move. You made enough force to the pie pan to cause it to zip out from under the cardboard tube (there’s not much friction against the drinking glass). The edge of the pie pan hooked the bottom of the tube, which then flew off with the pan. You knocked the support out from under the egg. For a small nanosecond the egg didn’t move because it was already not moving. But the force of gravity took over and pulled the egg straight down toward the center of the Earth.

Also, according to Mr. Newton’s First Law, once the egg was moving, it didn’t want to stop. The gravity-pushed egg caused the water to splash out. Did someone get wet?
