Radiometer and Plasma Ball

-DRIVING QUESTION:

Radiometer:

Why do the flags inside the Radiometer spin when light is turned on?

Plasma Ball:

Why does the light bulb light up when it's close to the Plasma Ball

-PHYSICS PRINCIPLES

Radiometer:

• Electromagnetic Radiation

• Pressure

Radiometer:

• Heat

• Electromagnetic Conductivity

1.INTRODUCTION:

• In my project I answer the questions "Why does the light bulb light up when it's close to the Plasma Ball?" and "Why do the flags inside the Radiometer spin when light is turned on?" These occur due to certain physics principles such as pressure and high voltage phenomena.

2.MATERIALS:

1. Radiometer

2. Light Bulb

3. Plasma Ball

3.PROCEDURE:

• Plasma Ball:

  • Gather materials: a plasma ball and a light bulb

  • Turn on the Plasma Ball and approach the light bulb towards it, notice how it immediately lights up!

  • No safety instructions needed

• Radiometer:

  • Gather materials: a lantern and a Crookes Radiometer

  • Light up the Radiometer, and watch it spin!

  • No safety instructions needed
