The festivals of lights- Diwali -was last month.We have all enjoyed ourselves
Many of us waited every night for the 5 days of Diwali just to burst crackers.
Its great fun the sparkles bombs and rockets.Something to know about sound
Sound is all around us-louder during the day and softer at night.Each sound is different
Do you know how sound is produced?Sound is produced whenever an
object is made to vibrate or move rapidly backwards and forwards.A
simple way to feel vibration is to hold a balloon that touches the front of a spesker
when music is playing.Try it- did you feel the balloon vibrate?Most
vibrations are too quick to see.As you grow and come to higher classes you will
learn more about sound.
The loudness of a sound is measured in decibels -db- look at the picture
below and see how loud a sound somethings you see almost daily make-
How can we help –
1. Speak softly dont scream.
2. Enjoy music but not so loud so that others get disturbed.
3. Use the horn only if you have to-learn to be a little patient.This is for
your dad/mum or your driver.
4. Dont bang doors and windows.You know by doing so you may only
damage them.Learn to gently close them -it dosent take time-try.
We all know that we hear with our ears.We enjoy soft and musical
sounds.Very loud sound are painful and disturbing,and loud sounds can
lead to permanent ear damage sometimes deafness.Have a look at the
picture below this is how your ear is outside and inside.You’ll learn about
it as you grow up.
