We enjoyed a more sheltered outdoor time on Wednesday afternoon. We enjoyed planting, weeding and mud kitchen culinary delights before the wind got up, when we retreated inside for hot chocolate and cake.
We wish you a super half term, Miss Chalcraft, Mrs Graham, Mrs White and Mr Wilkins Our Science topic has been Sound this half term, so we have explored sound made from a gramophone this week.
Like other record players, gramophones read the sound with a small needle which fits into the groove in the record. As the record turns, the grooves make the needle vibrate back and forth. These vibrations are transmitted to the diaphragm, which itself vibrates, creating sound. We hope you enjoy 'His Masters Voice' as much as we did. The children commented on the crackle of the record and by listening to it, they felt like they were going back in time. Several children talked about how the sound was amplified, sounded eerie and they commented on it being more reliable that modern day technology as there is less to go wrong and can be fixed easily. In Art, Mrs White has been continuing our History topic of Anglo Saxons by the children designing and making round houses, they are coming on a treat. We hope you have a lovely weekend, Miss Chalcraft, Mrs Graham and Mrs White Using our understanding of how sounds travels, the children were tasked with making ear defenders for children to attend a noisy rock concert. They talked in groups about which mediums would help muffle sound or not and why. It was a lot of fun, creative and the ideas were brilliant! We went into Yr3 and Yr5 to see if our designs worked when they made noise.
Here are some of the comments that were overheard: 'I found out that you need a few layers of wodding to block the sound, as with one layer it kept coming through' 'The egg carton worked well when stuffed with wodding, but it was difficult to attached it the head so I had to hold them on my ears'. 'The bubbles needed to stay in the bubble wrap to provide another layer to protect against loud sounds' 'Dense, soft materials like cotton wool and wodding absorb sound waves, so the waves go slower'. We hope you have a great weekend, Miss Chalcraft, Mrs Graham and Mrs White |
