As part of our current IPC unit on sound we have been focusing on ears! We started the week looking at pictures of different animals and deciding if they have big ears, or small ears. We read a text about why different animals have either small or large ears and the Year 2's used this information to write a fact for each animal. Do you know why the arctic fox has small ears, or why the elephant has big ears? The children developed an understanding that animals adapt to their environment!
Following on from this we had a scientific question to investigate - "If we had bigger ears could we hear better?" First of all the students made a prediction, then we did a test to find out if we could hear better with larger ears!
The students lined up on the playstreet, and Miss Lori shouted a sentence to us. First, we listened with our 'normal' ears...
Miss Lori then shouted again and we listened with a 'medium' sized ear...
Lastly, we listened with our 'large' ear...
The students all agreed that we could hear Miss Lori a lot louder with the biggest ear! They were very excited with the result! Back in class we wrote up our experiment and the children could see if their prediction was correct or not!
We followed up with a discussion about why we could hear better and how the big ears could collect more sound waves!
It was a fun and simple experiment! Next week will use the same process to test how sound travels through different materials!
Mid-week we also had a birthday celebration as Ansh turned 6 years old! Thank-you for the birthday treats Ansh!
Have a great weekend everyone!
