Year 4 have enjoyed taking part in Science Week this term. They loved learning about how electricity is made and how it travels to our homes.
Lennon’s explained how electricity is made and how it travels to our homes:
First, people heat things (fuels) and the heat makes the water get hot. After that, the water turns into steam which pushes turbines with a big magnet in them. The magnet makes electricity then it goes into a transformer to change the volts. Then it travels through the pylons to our home.
They sorted out which items needed or didn’t need electrical energy. They also decided which items needed battery power or electricity from a socket. They used Venn diagrams to show our findings scientifically.
They were able to make a simple circuit including a cell, bulb, switch and wire. They had retained this information from KS1. They learnt how to use symbols to represent the components of the circuit and then drew a circuit diagram. They investigated what happens when they add extra bulbs or wire.
They were given a scenario from which they created an investigation question. They needed to find which materials were the best at conducting electricity in order to use it to rewire the school electrics. The children designed an investigation considering variables and fair testing, agreed on a method and made a prediction as to what they thought would happen.
Orange table found that wool was a conductor of electricity but all of the other tables disagreed. The rest of the class found this was a false result due to the circuit not being connected properly. This was discussed in their evaluation. They found metal to be the best conductor.
After they had completed an evaluation of their investigation, they made some recommendations to be considered if the investigation was to be repeated.
Year 2 have had an amazing time learning all about living things.
They have worked hard to classify a selection of animals into carnivores, herbivores and omnivores.
Suzie has been exploring changes at home.
Paige and I were mixing materials at home. We experimented with three different bags of materials. The first bag was salad cream and gravy granules which was an irreversible change. Irreversible means that you can't separate the materials from each other. The second one we did was milk and orange juice which was irreversible. The final one we did was grass and water which was reversible. Reversible means that you can separate the two materials. We had lots of fun!
Jasmine and Jasmine took part in the Science Fair! They had such an amazing time.
It was so fun for us and we taught people more about parachutes. I think our stall was successful and we wanted to thank everyone who visited us and came to the Science Fair. We had lots of good reviews!
