Summer Term 1
Our topic this half term is sound. First, we went on a sound walk and talked about loud/soft sounds and natural/manmade sounds. Then we discovered how we hear a sound:
- the sound source vibrates
- the vibrations pass from the sound source to the particles in the air
- the vibrations reach your ear
- in your ear, they are changed into electrical signals and sent to your brain
- your brain tells you that you are hearing a sound.
Did you know that if you place your hand on your throat when you talk, you can feel the vibrations? Try talking loudly and then quietly. What happens?
Next, we investigated the loudest and quietest places in school. Here are some line graphs of some of the places we explored.
We had lots of fun making string telephones and we learnt that sound travels better through a solid than a gas (air) because the particles are much more tightly packed. If you try this at home, remember to hold the string tight.
Also in our topic we have investigated how to protect our ears from a loud sound, discussed how fast sound travels, classified different types of musical instrument and investigated how to change the pitch of a sound. Our homework project this half term was to design and make a musical instrument…they were fantastic!
Also, we have really enjoyed our writing topic this half term because we have focused on African animals. First, we wrote some animal poetry using descriptive language and then we wrote a story based on an animation called ‘Catch It.’ Finally, we split into four groups: ‘Save the Black Rhino,’ ‘Save the African Elephant,’ ‘Save the African Lion,’ and ‘Save the Amur Leopard.’ We made animal fact files and created a TV advert to persuade the governors to adopt our animal. The winning team will get their animal adopted for Class 3.
In art, we created an African sunset using our own choice of media. Some of the class chose paint and some chose chalk. We also studied drawings by Henry Moore and learnt how to use one pencil to create different tones and textures. Take a look at some of our amazing artwork.
