Whether we are driving around in our cars, working, or relaxing at home, we are turning on lights, music, TV, radio, computers and mobile phones. We are plugged in to sound and light 24 hours a day. But what is the science behind sound and light? Electricity is one of the most important discoveries ever made and we have learned how to use it to power almost every aspect of our lives. Who discovered electricity and how does it work? As Scientists we will investigate insulators and conductors and learn how to conduct a fair test to extend and develop our understanding of electricity.
Moving on from our electricity science, we have now started to learn about sound and what better way to begin than with a lesson with Mr Cook! As we are going to be creating musical instruments it was really interesting to learn about the 4 different ways instruments can make sounds; chordophones (strings), membranophones (drum), aerophones (air) and ideophones (xylophones). We were really impressed with all the makeshift instruments Mr Cook had that could easily be made at home!
Adele came in last week for more yoga. We learnt how to belly breathe and worked on our balance, doing yoga moves with whilst making sure the beanbag wouldn’t fall off our head.
We have been writing quest stories after reading ‘The Firework Maker’s daughter.’ We created a story map and made sure our writing had fronted adverbials, expanded noun phrases, adventurous vocabulary and conjunctions.
In Science we have been finding out what materials are conductors and insulators. We set up a fair test, making sure we only changed one variable, which were the materials.
English Heritage Conservation in Action Roadshow
We were very lucky on Tuesday when English Heritage’s Conservation in Action Roadshow came in to visit us. They set up numerous activities: identifying bugs in homes, renovating paintings by washing away dirt, seeing how much light is in mosaic pictures and digging for artefacts.
In Science we were challenged to create a complete circuit and an incomplete circuit, explaining why it was incomplete. All groups came up with different ideas.
We took out the battery so the current could not flow.
Our wires connected to plastic on the light bulb holder and not metal.
We took out one of the wires so there was a break in the circuit.
In our one nothing was connected up.
Last term we imagined, designed and created our own mosaics. We learnt about the purpose of Roman Mosaics and how they give us first-hand information about life in Roman times. We looked at examples and gave our opinions of them and then designed and created our own Roman Mosaics. We even grouted and polished them once they were dry. We think they are amazing!
We rubbed a balloon against our jumper and then put it above our heads. Our hair stood up
I think static electricity is when there is friction between the balloon and the jumper.
The harder we rubbed, the more hair stood up.
The lemon has acid in it and that helped the electricity flow.
We needed to make a complete circuit for the electricity to flow.
The coin in the lemon lit up the bulb but the screw didn’t.
The coin was a better metal.
The light was brighter when we had less wires.
It was hard but really funny.
