Welcome to Mexico class. Mrs Taylor is our teacher. Mrs Forsdick and Mrs Laker-Jones are our teaching assistants.
This week we have been busy designing and making prototypes for ear defenders. The children have been learning about ‘muffling’ and sound-proofing materials. Based on their results from a previous investigation where we measured sound in decibels, they selected the most suitable materials to create their ear defenders.
They then tested them, and adapted their defenders to make any improvements. It was lots of fun!
In P.E we have been learning to attack and defend in netball, and tried our hand at goal shooting.
Topic work took us to the Iron Age and we imagined that we were in a Celtic village after visiting our round house. We took on different roles as villagers and learnt that everybody depended on everyone else doing their job such as hunters, famers, cooks and blacksmiths. We brought our jobs to life through outdoor drama work. It was lots of fun.
Out of this world, continuing our Sci-Fi theme in English, we worked on inventing alien and Sci Fi characters. This lead us on to trickery using the iPads on the Photo Booth app. We created self-portraits in our alien image!
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 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.
