What is current electricity? Current electricity is power or a charge that flows in and out through a medium such as electrical wires. It can be stopped or started by opening or closing the wire connection as in turning a light switch from off to on.
Why do we need current electricity? • We need current electricity because without it we would not have xbox 360 or wii. We need it in everyday appliances like a vacuum, hair dryer, and even your computer.
What is static electricity? • Static electricity is electricity stored in objects then released when it touches an conductor. It is important to understand it because it happens everyday, when you walk across the carpet in socks, your socks take in the electricity and channels it to your body and then you touch a door knob.
What are the dangers of current and static electricity? • Current electricity can be channeled the wrong way and electrocute you. Static electricity is dangerous because big charges are lightning.
safety procedures for dealing with current and static electricity. Don’t drag your feet on the carpet, don’t stand outside in the rain with a medal umbrella. Where rubber gloves when you turn on a light, and when you unplug a TV computer or anything with a wire.
How to separate salt and pepper!!! • • • • This experiment shows how to separate pepper and salt using a balloon and static electricity. Equipment needed: One balloon (a comb and some plastic hairbrushes will also work well for this, particularly if you’re worried about the balloon bursting) A cloth (wool will work best) Salt Pepper Safety glasses The Digital Bits Science Lab Experiment: Wear safety glasses for this experiment – you don’t want salt or pepper getting in your eyes. Mix a small pile of salt and pepper. The challenge here is to separate the salt from the pepper. It’s easy if you have a balloon: inflate the balloon. Rub the cloth on the balloon, and the balloon will become negatively charged. This means the balloon will become attracted to objects that have a different charge. Luckily for us, the salt and pepper fall into this category. After charging the balloon, hold it above the salt and pepper mixture and slowly bring it closer. You’ll see the pepper fly up and stick to the balloon, leaving the salt behind. The salt stays put because it’s heavier than the pepper. This is why you want to move slowly, because if you move too close too fast, the salt will also fly up and attach to the balloon. When you’re done, you can either wipe or wash the balloon off to remove the pepper. Don’t pop it, or you’ll get pepper everywhere!
