No, at least not using everyday paper. NB: We've had some feedback about this one. The 'Mythbusters' show did try this and get 8 folds, however this required a paper sheet the size of a football field and further folding required a steamroller! Check this link. Of course, this is a Wikipedia stub and as such needs further verification on its statements. We've followed the stated instructions and only achieved a "7 fold" a couple of times. For most cases it really isn't possible.

Question: 10

What does TCP/IP stand for?

View the answer

Transmission Control Protocol / Internet Protocol.

Question: 11

What's the highest recorded surface wind speed?

View the answer

372 km/h! Over Mt Washington, New Hampshire on April 12, 1934.

Question: 12

What is the name of the layer of air closest to us in the atmosphere?

View the answer

Troposphere

Question: 13

True or false - is lightning 3 times hotter than the Sun?

View the answer

True

Question: 14

True or false: When lighting hits a tree the water inside the tree boils and expands, blowing the tree apart.

View the answer

True

Question: 15

Is the stratosphere above or below the troposphere?

View the answer

The stratosphere extends 50 km above the troposphere

Question: 16

Why is Merino wool so good at keeping you warm in winter?

View the answer

Merino wool fibres are wavy, not straight. Wavy wool traps air which is an excellent insulator. This trapped air can be heated by the body. 'Fine' wool fibres have 12 repeating waves for every cm, whereas 'coarse' wool fibres have less than 2 waves per cm. Merino wool can be 'super fine', making an awesome material for warm sweaters

Question: 17

How many volts can an electric eel produce?

View the answer

Around 500.

Question: 18

True or false: The Eiffel Tower is taller in summer than it is in winter.

View the answer

True. Metals expand as they are heated, and this can cause metal structures to stretch with temperature changes.

Question: 19

What is the word ‘radar’ an abbreviation for?

View the answer

Radio Detection and Ranging.

Question: 20

What year was the sound barrier broken?

View the answer

The ‘sound barrier’ refers to the speed of sound and breaking it means travelling faster than sound itself. It was first broken in 1947.

Question: 21

On the moon, which would hit the ground first if they were dropped from the same height and at the same time: a feather or a bowling ball?

View the answer

Neither, they would hit the surface of the moon at the same time.

Question: 22

Is it possible to physically stop light from moving?

View the answer

Yes, and scientists have done so!

Question: 23

What unit is used to measure the intensity of light?

View the answer

Candela (cd)

Question: 24

What does the acronym ‘LASER’ stand for?

View the answer

Light amplification by stimulated emission of radiation

Question: 25

What rock floats in water?

View the answer

There is only one - pumice. However, once water enters into the rock itself it will then sink.

Question: 26

Which freezes faster, hot water or cold water?

View the answer

Cold water.

Question: 27

What is the hardest known substance?

View the answer

Diamond

Question: 28

What is the speed of light?

View the answer

300 million meters per second.

Question: 29

Does light travel faster through air or water?

View the answer

The speed of light in a vacuum is 299,792,458 metres per second (lets call this 300,000,000 metres per second as an approximation!). However, as the density of a material increases so does its refractive index (which in turn affects the speed of light in that material). In this case, air is less dense than water and does not slow light down as much as water does. In short, light is faster in air than in water.

Question: 30

When you mix red and green light, what colour light is formed?

View the answer

Yellow (mixing light is very different from mixing paints)

Question: 31

The word “force” comes from the Latin word “fortis”, meaning:

View the answer

Strong

Question: 32

Your weight tells you how much stuff makes up your body.

View the answer

False. That is mass! Weight is actually the force of gravity on an object. Our weight on Earth is how much force the Earth's gravity has on us and how hard it is pulling us. So if we use the same scales to measure our weight on Earth and on Mars, it will show different numbers (60 kg vs 22.7 kg), but our mass will stay the same.

Question: 33

What is the name of the force keeping you in your seat on a rollercoaster when it goes upside down?

View the answer

Centripetal force. This keeps you moving in a circular motion instead of you being flung out of the curved path of motion.

Question: 34

When the roads are wet, sometimes that water reduces friction between the tyres and the tarmac and causes our cars to lose control. What is this called?

View the answer

Aquaplaning

Question: 35

Scientists often talk about “Classical Mechanics.” What does this mean?

View the answer

Describing how things move according to Newton’s Laws.

Question: 36

True or false: gravity can be so strong that it even pulls in light.

View the answer

True: When an object is massive enough it’s gravity can pull in light faster than the light can escape. These objects are called black holes.

Question: 37

Which muscle in the human body can produce the most force for its size?

View the answer

The masseter in your jaw. When an adult bites down hard, they can exert a force of 90N on their back teeth. That’s like sitting a 90kg weight on your molars!

Question: 38

Which is the strongest fundamental force in the universe?

View the answer

Strong nuclear force. It's 6 thousand trillion trillion trillion (that's 39 zeroes after 6!) times stronger than the force of gravity.

Question: 39

True or false: Isaac Newton was Albert Einstein’s great-great-grandfather.

View the answer

False. They’re not related at all.

Question: 40

What do we call the study of how objects move when forces act on them?

View the answer

Dynamics

Question: 41

True or false: You must touch an object to apply a force to it.

View the answer

False. There are forces that do not require the objects to touch in order to act on them, these are called non-contact forces. E.g. magnetic forces.

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

Welcome!
