Science Activity

Make Your Own Ear Trumpet

Steps: Tools: a large cardboard, transparent tape, scissors and a radio.

1

Roll the cardboard into a cone and fix it with the tape.

2

Cut out a handle and attach it to the cone (this step is optional).

3 Turn on the radio and turn the volume down to a low level. Place the tip of the cone close to your ear, let the other end of the cone face the radio and listen carefully.

4

Notice how different the sounds are with and without the cone.

Caution Don’t place the tip of the cone into your ear. Just place it close to the entrance of your ear.

Conclusion

The visible part of the ear is called the auricle and is used to gather sounds. The auricle can only collect a small amount of sound but the cone can enlarge the auricle so that more sounds can be collected. The sound becomes more concentrated when it passes through the cone and reaches the auricle. As a result, the sound is louder and clearer.

Travel

Sax

I’ve been abroad for a week. I wonder if they missed me. What happened while I was away? Why are there dark circles under your eyes? We haven’t been able to sleep well for a couple of nights. Knock! Knock!

I’m back!

Deloitte,

welcome back.

Aw, did you miss me that much?

No. We couldn’t go to sleep because of Dicky.

It’s Dicky blowing on the saxophone. Because of Dicky? What’s that

sound? This is the sound that kept us awake.

Deloitte, you’re back! Dicky, since when did you fall in love with the saxophone?

Now I Know! Now I Know!

The saxophone is a musical instrument that is blown by the mouth. The music from the saxophone is loud, therefore, it is not easy for players to find the right place or time to practise playing the saxophone.

I become interested in the saxophone a few days ago. I have been learning ever since.

But you practise late every night. Tony and I can’t sleep because of the sound of your sax.

I have a gift that is just right for you. Ta-da! This is a Travel Sax! I’m sorry. That’s the only time I

can practise.

Now I Know! Now I Know!

The Travel Sax weighs only 300 grams and is 22 centimetres in length. It is about the size of a mineral water bottle. It is easy to take the Travel Sax anywhere.

This saxophone is very small! The Travel Sax can achieve a similar effect as a real saxophone. It can also directly output signals to these headphones. Wow, it’s light! And now I won’t disturb others when I practise. The Travel Sax consists of the key parts of a

saxophone.

From now on, we’ll get a good night’s sleep.

Now I Know! Now I Know!

Travel Sax users can play, record or even learn the saxophone at any time through the official app. It can easily be paired with any smartphone device via Bluetooth.
