Mexico

Welcome to Mexico class. Mrs Taylor is our teacher.  Mrs Forsdick and Mrs Laker-Jones are our teaching assistants.

This week in Year 4 Mexico class we have been learning about how sound travels

September 14, 2020

Vibrations.

Our learning objectives were:

Identify how sounds are made, associating some of them with something vibrating

Recognise that vibrations from sounds travel through a medium to the ear

Recognise that sounds get fainter as the distance from the sound source increases

The children investigated how musical instruments were played and how we heard the sounds.  We talked about vibrations, and listened to tuning forks and felt the vibrations in our hands.  We could see the vibrations moving water when we submerged the tuning fork into a bowl of water.  The children also understood sound travelling through vibrations using elastic bands and looking at grains of rice moving on top of a drum.

We carried out an investigation by making our own cup and string telephones.  It was lots of fun!

We looked at whether we could hear more clearly when the string was pulled taut, or when it was loose.  We found out what happened round corners, and the effects of putting a knot in the middle of the string.

We know that light travels faster than sound, but sound can change speed depending on what medium it is travelling though.  Sound travels fastest through solids, and slowest through air.  Think about whether you can hear sounds underwater (how do whales and dolphins communicate?).

Mexico Class 11th September

September 13, 2020

Mexico class have had a very busy first week back in school!  It was lovely to see everyone’s cheerful faces, and we all agreed that it was fun to be back together as a class again. 

We carried out a science lesson introducing us to Sound.  To help us think about how we take hearing things for granted, we conducted a ‘Sound Walk’ around different parts of the school.  We then compared what sorts of sounds we heard where, and whether they were loud, soft, sudden or continuous.  Some continuous sounds were hard to even notice because we are so used to hearing them e.g. traffic.
