If I ask you to shut your eyes and gave you a piece of apple to eat, would you be able to tell me what it is just by tasting it? Of course, you could. Your tongue is covered with tiny “taste buds” which help you know what different foods taste like. Do you know that foods would taste different if you did not have a nose? This experiment shows how important your nose is when you taste things.

What You Need:

• a friend to help

• small pieces of any food like carrot, orange, banana

• small pieces of apple, raw(生的) potato, and onion

What You Do:

There are actually three different experiments. You and your friend should take turns to try them on each other.

Experiment 1:

Have your friend close her eyes and open her mouth.

Give her a piece of the food and ask her to taste it.

Then, ask her what she thinks it is. She will probably guess correctly.

Experiment 2:

While your friend has her eyes closed, give her a piece of the raw potato. At the same time, hold a piece of apple right under her nose. Ask her to eat the potato (but don’t call it by name) and tell you what she thinks it is. She will say it is a piece of apple!

Experiment 3: (for the brave)

Take a piece of raw onion. You don’t have to close your eyes this time. Squeeze your nose closed with your other hand so that no smells can get into your nose. Now take a nibble of the onion. Surprise! As long as you hold your nose, you will not be able to taste the onion.

The Science Secret

You already know the science secret. Your nose and your tongue work together to make food taste the way it does. Your tongue, however, can taste only certain flavors like salty, bitter, sour, and sweet. All of the other “tastes” are actually “smells,” and you need your nose to “taste” them. Oh, and you might use this science secret the next time you are told to eat something you don’t like the taste of. If you hold your nose while you eat it, you won’t “taste” it at all.

There is nothing worse than the sound of someone snoring (打呼噜) if you are trying to fall asleep. Maybe people laugh at you about the noise you make in your sleep. Snoring isn’t just noisy. Sometimes it is a sign of a serious medical problem that should be treated by a doctor.

Snoring can happen to anyone, young or old. Snoring happens when a person can’t move air freely through his or her nose and mouth during sleep. People usually find out they snore from the people who live with them. Kids may find out they snore from a brother or sister or from a friend who sleeps over. Snoring keeps other people awake and probably doesn’t let the snoring person get top quality rest, either.

People with this disorder often wake up with bad headaches and feel exhausted all day long. They may be very sleepy and have difficulty staying awake while having a conversation or even while driving. Kids affected by snoring may be angry easily and have difficulty concentrating(集中注意力), especially in school and with homework.

According to the government survey, there are hundreds of anti-snoring devices（抵制打呼的设备） on the market. However, they may only work because they keep you awake. Other solutions include blocking the top of the bed up a few inches, changing sleeping positions and not eating a heavy meal or not drinking alcohol before bedtime. These kinds of “cures” may work only for someone who snores sometimes and lightly, or they may not work at all. If you can’t stop snoring or the snoring becomes heavy, it’s a good idea to see a doctor. Some people need to lose weight or change their diets to stop snoring. Sometimes medicines, or even surgeries are necessary.
