ABCs of Electricity
ELECTRICTY SAFETY AND YOU
- Don’t climb fences near electric substations. If you lose your ball, ask an adult to call the power company –– they will come out and return it to you.
- When unplugging an appliance, do not yank on the cord. Pulling on the cord will damage the cord, appliance or the outlet.
- Fly your kite far away from power lines or substations.
- Always check for power lines before you climb a tree. Electricity can go right through a tree branch and right through you.
- Keep electrical stuff away from water.
FUN FACTS — DID YOU KNOW?
There’s Electricity In YOU
- Electricity plays a role in the way your heart beats. Muscle cells in the heart are contracted by electricity going through the heart.
- Electrocardiogram (ECG) machines used in hospitals measure the electricity going through someone’s heart, when the person is healthy it usually shows a line moving across a screen with regular spikes as the heart beats.
Electricity In the Animal Kingdom
- Electric eels can produce strong electric shocks of around 500 volts for both self-defense and hunting.
- Bees are attracted by a flower's bright petals and fragrance — but that’s no all! Flowers often experience a change in electric charge after they've been visited, so by sensing electric fields, bees can decide whether a flower is worth investigating (or if someone got there before them).
- 25,000 fireflies equal one 60-watt incandescent light bulb.
- Ever wonder why birds can sit on power lines but not get shocked? Because electricity is always looking for a way to get to the ground, birds are safe because they are not touching the ground or anything in contact with the ground.
