Laser experiments you can share with Homeschool Kids

The word "LASER" represents light intensity with activated radiation emission. A laser is a light source that emits a focused beam of light. Lasers are usually monochrome – the light that shoots is usually one wavelength and color and is in a narrow beam.

Light from a standard incandescent light bulb, however, covers the whole spectrum and spreads throughout the room. (Which is good because you can light up a room with a narrow beam of light?)

There are about 100 different types of atoms in the entire universe and they are always vibrating, moving and rotating. Think about the kids on sugar. When you add energy to this atom (even more sugar to the kids), they will be really excited and jumps all over the place.

When the atoms relax back in honor of "normal" conditions, they emit a photon (photon). Think of the kids who come down of their sugar high, and everyone collapses on the couch.

A laser controls how power tablets release photographs. Imagine giving half of the kids sugar and figure how they would jump all over (like light bulb) when it came into effect. They would be very high-energy among the other half that could sit down.

Imagine now that this sugarcrumb leap in private space (focus laser beam). The sugar-kids are catching, and almost soon, the kids around them are participating in and sharing exciting energy. This is how the laser charges the atoms in the gas.

Imagine a cat that allows you to get a limited number of kids at once, but the rest is bouncing around you and charging everyone. This cat-flap stop is a laser beam stopping the laser. The atoms that are inside the laser lamps on mirrors like they charge each other.

Before we start, you need to protect your eyes – colored UV ski goggles are great to use, like a large frame of shades, but understand that these eye protection methods will not protect your eyes from direct rays. They are intended as general precautions for radiant voltage and spinning mirrors. (Yes, you must wear sunglasses in the dark!)

A very cool addition to the experiments below is a fog machine. (Rent one of your local retailer.) Turn it on, make sure you have good ventilation, dark lights and turn on the laser for outstanding laser experience!

A quick comment about lasers: keyboard lasers from the dollar store work just fine with these projects. Do not use green lasers sold in astronomy – they are too dangerous to the eyes.

Plastic bottle beam: Fill a plastic or a clean bottle of water with water and mix with a sprinkle of corn starch. Turn the lights down and turn the solvent up and defeat the beam in the bottle. Do you see the original beam in the bottle? Can you find the mirror beam and the front light?

Light bulb: In the dark, aim your laser with a frost glowing light bulb. The glow will glow and have some inner thoughts! What other types of light bulbs work well?

CDs: Scan your beam over the surface of the old CD or DVDs. Does it work better with scratch or smoother surface? You should see between 5-13 reflections of the surface of the CD, depending on where you shine and how good your "see" conditions are.

Glass and crystal: Match the beam light through a few cut crystal objects like wine glasses or clear glass pockets. Is there a difference between clear plastic or glass, smooth or multipurpose? Try the sprayer, both matt and wet.

Lenses: If you have an old pair of glasses, shoot your lenses and try one or both of the beams to see different effects. Try one lens and then try two in tandem with each other to see if you can change the beam. If you have polarizer filters, use two. You can replace two shades of lenses – no need to pop out the lenses – you can only use two pairs of shades. Make sure they are polished lenses (most UV shades are). Put both lenses in a beam and turn 90 degrees. The lenses should close the light completely in one configuration and allow it to go through the other direction.
