This week we have been investigating which materials best muffle sound. We predicted that fur will best muffle sound as it is thick, this makes it harder for the vibrations to travel through the material.
Have you ever wondered how the moving parts in your favourite story books are made? We have been busy this week investigating and trying out the different techniques involved in bringing some of our favourite stories to life. Look at our springy snakes. We made these using a linkage system. We had a lot of fun making them and it has inspired us to keep creating!
We had fun discovering that sounds are made when objects vibrate. We described what we could see, hear and feel. It was quite easy to see the guitar strings vibrate when we plucked them and although we couldn't see the tuning fork vibrate, we could see the water splash as soon as the tuning fork touched it!
This week, Year 4 welcomed Janet from United Utilities. She delivered a Water Awareness Workshop which helped us to learn more about how we use water in the UK compared to other parts of the world. We were able to name and explain the stages of the natural water cycle together with those in the water treatment process. Janet also made us aware of how easy it is to waste water. Did you know leaving the tap running when you brush your teeth could waste up to 24 litres of water? We were shocked. We will all be turning the tap off in future!
We have some talented up and coming musicians in Year 4!
They are enjoying learning new tunes on their recorders.
The children enjoyed this role play activity. Their suggested thoughts for each character showed their understanding of the mood and tone of the scene.
This term, Year 4 have learnt lots about the three different states of matter. We have grouped materials into solids, liquids and gases; observed and researched the temperatures some materials change state and used thermometers to measure temperature in degrees Celsius and lots more!
We especially enjoyed investigating the properties of gases and proving that just because we can’t see air, it does have mass. We had to work very hard as a team to push and pull the parachute up and down.
We are super star scientists!
This term, Year 4 are enjoying reading and writing about Anthony Browne’s, Gorilla.
Today, they have been busy gathering gorilla facts from information stations around the classroom before creating their own gorilla fact files tomorrow.
Great work Year 4!
