Energy Trivia

Question: 1

Which colour light has the most energy? Red, orange, yellow, green, blue, indigo or violet?

Violet. Violet light has about 1.5x as much energy as red light.

Question: 2

True or False: Some plants get their energy from eating bugs.

False. There are plants that eat bugs, but they do it to get vitamins, minerals and other nutrients. Those plants still get their energy from the light of the sun.

Question: 3

If you could gather all the energy in a lightning bolt how much would it be?

View the answer

The average lightning bolt contains about 5,000,000,000 joules. Scientists usually say this number as 5 gigajoules. This is equivalent to exploding 1000kg of TNT!

Question: 4

Energy cannot be created or destroyed. What do scientists call this rule?

View the answer

The Law of Conservation of Energy.

Question: 5

Which organ in your body uses the most chemical energy?

View the answer

Brain. About 20%! And about ⅔ of it goes towards firing and receiving signals through neurons and nerves.

Question: 6

True or False: you can cook food using sound

View the answer

True. Remember that sound is another kind of energy and can transform into heat. You'll need a lot of sound for a very long time though!

Question: 7

True or False: Sydney was the first town in Australia to have electric street lights.

View the answer

False Tamworth in NSW switched on arc and incandescent street lights in 1888.

Question: 8

The longest human electrical circuit ever made had how many people in it?

View the answer

1315. The longest human electrical circuit was achieved by Presbyterian Ladies College in Sydney, New South Wales, Australia, on 20 August 2015. The attempt took place as part of National Science Week.

Question: 9

What’s the highest voltage ever recorded from an electric eel?

View the answer

860 volts. That’s the equivalent of 575 AA batteries! It comes from a species discovered in 2019, Electrophorus voltai. One of the scientists, speaking from personal experience, said that a person probably wouldn’t feel a difference between a shock of 500 volts and anything higher. “It just hurts,” he says. High voltage but low amperage.

Question: 10

True or false: The word “electrocute” comes from the English words “electricity” and “execute”.

View the answer

True. So you’ve only been electrocuted if you die. Otherwise, you’ve just been shocked.

Question: 11

The word “electric” comes from the Greek word elektron, which means...

View the answer

Amber. William Gilbert, an English physician, physicist and natural philosopher, used amber to study static electricity.

Question: 12

In 1752, American Benjamin Franklin proved that lightning is an electrical phenomenon. His experiment used:

View the answer

A kite, a key, a silk ribbon, a metal wire, and a special jar for storing electricity.

Question: 13

A pacemaker is a small device some people have installed in their chest or abdomen. It uses electrical pulses to do what?

View the answer

Keep your heartbeat regular.

Question: 14

True or false: Electric cars have been around for over 100 years.

View the answer

True. William Morrison of Des Moines, Iowa built the first successful electric automobile in the United States in 1891. In 1900 about one-third of all cars found on the roads of New York City, Boston, and Chicago were electric.

Question: 15

Can cockroaches sense electrical fields?

View the answer

Yes!

Question: 16

Which scientist first measured the speed of light?

View the answer

Ole Rømer. He used planets to help him calculate the speed of light. His methods were so accurate that the only reasons his measurements were not closer was because other people’s calculations of planet sizes/distances were a bit off.

Question: 17

What is the speed of light (in vacuum)?

View the answer

300 million metres per second (that’s 8 zeros after the 3!)

Question: 18

A rainbow has the colours red, orange, yellow, green, blue, indigo and violet (ROYGBIV) in that order from outside to inside. What is the colour order of the secondary rainbow from a double rainbow?

School Comments View All

I just wanted to pass on how much the staff and students really enjoyed it and how perfect it was to launch our science week activities. The students were enthralled, educated and entertained – a perfect trifecta!

-Caulfield Grammar School – Big Science Big Fun

Thanks so much for presenting at our school on Monday. Our students enjoyed the show.

-Greenvale Primary School – Big Science Big Fun

Fizzics Education curated a thoughtful and hands-on experience for the children, incorporating practical, skill-based learning activities and followed by a science presentation at the end of the event involving liquid nitrogen. This was delivered safely and effectively, capturing both the children and the parents for the duration of the presentation.

-Macquarie Bank – Family Fun Day

Fizzics Education ran a show today at our school and it was wonderful. He was a great facilitator and the show was age appropriate and well done.

-Mount Zion Early learning centre – Little Science Big Fun
