Sugar and Spice and All Things Nice... Quiz

Answer: Each side of the brain controls the opposite side of the body.

The brain does a lot more than just control each side of our bodies, it is the part of us that thinks and remembers. Brains can be different sizes for different people but having a big brain does not make you cleverer, any more than having bigger feet would make you a faster runner!

Answer: True

We are born with about 350 bones but by the time we stop growing we will only have just over 200 bones. This is because as we grow some of the smaller bones join together to make bigger ones.

Answer: A pigment called melanin.

People with dark skin have more melanin than people with light skin. Our skin gets darker when we have been in the sun as the rays from the sun cause an increased release of melanin. However, whether you have light or dark skin, too much sun can burn you so you should always wear a hat, sun-protective clothes and sun-protection cream.

Answer: They make themselves shorter.

Muscles are fixed to our bones by long white strings called tendons and when the muscle gets shorter it pulls the bone. Muscles can only get shorter so they need to work in pairs to move bones in two directions. To move the bone back, another muscle gets shorter and this stretches out the first muscle again.

Answer: By using chest and abdomen muscles.

We breathe by using muscles in our chest and abdomen (the abdomen is our stomach area). When our chest gets bigger air rushes in to fill the gap. Our body takes the oxygen from the air and gives back carbon dioxide and when the chest relaxes and gets smaller the air rushes back out.

Answer: No

Hiccups are caused by the diaphragm muscle pulling down very hard and drawing lots of air into our lungs. To stop the air a flap at the top of the windpipe clamps down. The "HIC" sound is the air rushing in and the "CUP" is the sound of the flap clamping down over the windpipe.

Answer: Lub-dub, lub-dub.

If you want to listen to a friend's heart beat find somewhere quiet and rest your ear against their chest. Our blood carries useful things, like oxygen and food, all around our bodies. It also has cells in it which help to fight germs.

Answer: To catch sounds from the air.

The sounds that are caught go through your ear holes into the hidden part of your ears. Some animals, like rabbits, have very big ears which they can move to catch sounds in the air. It is important for them to hear things very well to stay away from danger.

Answer: For smelling and tasting.

Whilst we smell with our noses, they also help us to taste things. It does this as tiny bits of food, too small to see, are carried up the nose and messages about them are sent to the brain. This helps us with our taste and is why, if you hold your nose when eating, you can't taste very well.

Answer: There is gas in the tummy.

If you don't eat something for a couple of hours your tummy fills with air-like stuff called gas. When your tummy makes the same movements it makes when there is food in it the gas gets squeezed and this makes the rumbling sound we hear.
