KS2 Science Quiz: Explore the World of Muscles

Science Quiz - Muscles (Questions)

Get ready to flex those brain muscles in our exciting KS2 Science quiz! We're diving into the world of muscles, not just in humans but in animals too. This quiz explores the different types of muscles, what they're made of, and how they work by squeezing and relaxing.

Muscles are like magical tissues that make animals and humans move. They're made of stretchy protein fibres. Fun fact: 'muscle' comes from the Latin word for 'mouse' because moving muscles reminded people of mice. Check your biceps in the mirror and see if you agree!

Do all animals have muscles? Which muscle relaxes when you flex your biceps? Test your muscle knowledge with this awesome KS2 Science quiz!

Science Quiz - Muscles (Answers)

What are muscles made from?

[ ]	Fat cells
[ ]	Thin strands of iron
[x]	Thousands of small stretchy fibres
[ ]	Carbohydrates

Each muscle is actually a bundle of small stretchy fibres made from protein

How do voluntary muscles always work?

[ ]	Voluntary muscles always work on their own
[x]	Voluntary muscles always work in pairs
[ ]	Voluntary muscles always work in groups of three
[ ]	Voluntary muscles always contract at the same time

Voluntary muscles are the muscles you can control. They are also called 'skeletal' muscles. Involuntary muscles are also called 'smooth' muscles

When you contract your bicep, what happens?

[x]	Your tricep relaxes
[ ]	Your other bicep also contracts
[ ]	Your arm lowers
[ ]	Nothing else happens

Muscles work in pairs: when you contract your tricep, your bicep relaxes and when you contract your bicep, your tricep relaxes

What attaches muscles to the skeleton?

[ ]	Ligaments
[ ]	Joints
[x]	Tendons
[ ]	Arteries

Ligaments hold bones together at the joints

Which of these is not an involuntary muscle?

[ ]	The heart
[ ]	The diaphragm
[ ]	The muscles lining the stomach
[x]	The tongue

The diaphragm (the powerful muscle under your lungs) is interesting - you don't need to make it contract (because it's involuntary), but you can if you want to. That's why people can control their breathing but don't have to think about every breath

Skeletal muscles are usually attached to bones at both ends. Which muscle is an exception?

[x]	The tongue
[ ]	The gluteus maximus
[ ]	Pectorals
[ ]	Triceps

The tongue is only connected at one end - otherwise, how would you be able to chew and swallow, or even talk?

What do your muscles need in order to work?

[ ]	Carbon dioxide and energy
[x]	Oxygen and food
[ ]	Nitrogen and energy
[ ]	Carbon dioxide and blood

The cells in the muscles can convert oxygen and food into energy

Exercise makes muscles do what?

[x]	Grow bigger and stronger
[ ]	Grow smaller and weaker
[ ]	Become less stretchy
[ ]	Become less effective

The more you use a muscle the bigger and stronger it gets, but if you don't use it, a muscle gets smaller and weaker

Your facial muscles allow you to do what?

[ ]	To use your brain
[x]	To make different facial expressions
[ ]	To hear
[ ]	To lift heavy weights

You have more than 30 facial muscles. These allow you to make an enormous range of facial expressions

[ ]	Snakes have very strong muscles to help them move
[ ]	Some insects have thousands of muscles
[x]	Humans are the only animals with muscles
[ ]	Birds need powerful muscles in order to fly
