Matter of the day:

Light Bulbs

Diagram:

What is it?:

In 1879, Thomas Edison’s design team developed a carbon-filament light bulb in a vacuum to prevent burn-out. Different inert gases like argon, nitrogen, krypton, neon, xenon, and halogen.

Why does it matter?.

The major form of lighting for over 100 years.

Vocabulary:

Electric force is the attraction or repulsion between electric charges.

Chemical Energy is the energy stored in substances.

Batteries change chemical energy into electrical energy.

terminal: the points on a battery where electricity flows.

Circuit:a a path that allows electrons to flow.

Current:the flow of electrons.

Volt: the potential for the flow of electrons from a source.

Conductor:a material that allows electrons to flow.

Insulator:a material that prevents electron from flowing.

Resistor:a material that slows that flow of electrons.

Dry Cell Battery:

Diagram: 

What is it?: 

A battery that uses a chemical paste electrolyte for the reaction to move electrons. Rolled graphite, zinc, and a chemical paste eletrolyte.

Why does it matter?.

Most of the batteries we use are of this type.

Matter of the day:

Magnetic Levitation Trains (MagLev)

Diagram:

What is it?:

A near frictionless train that rides smoothly and can travel at over 500 kilometers per hour. Opposing magnets suspend the weight of the train and its passengers. At slower speeds, it is nearly silent.

Why does it matter?.

It may become a major public transportation system in the future.

_____________________________________________________________

Vocabulary:

magnet :any material that attracts iron and materials that contain iron.
magnetic pole: The ends of a magnet where opposite forces are strongest.
The attraction or repulsion between magnetic poles is magnetic force.

The area of magnetic force around a magnet is known as its magnetic field.

magnetic domain: electrons spnnning in the same direction make a material magnetic. The more spin in the same direction, the stronger the magnet

Electron Microscope

Diagram:


What is it?:

By using electrons instead of light, we can see things as small as individual large atoms. The electrons are shot a the target using magnetic ‘lenses’ to focus the beam.

Why does it matter?.

It gets real images of many of the smallest things that we can see.

Vocabulary:

electron: negatively charged particles that surround an atom’s nucleus that have almost no mass.
magnet :any material that attracts iron and materials that contain iron.
magnetic pole: The ends of a magnet where opposite forces are strongest.
The attraction or repulsion between magnetic poles ismagnetic force.

The area of magnetic force around a magnet is known as itsmagnetic field.
