Sparks Might Fly – Autumn 1

Class 4

Miss Nicholson

We have had a great time learning about electricity in our first half term! Here are some of the things we have done:

Identified appliances which run on electricity:
We used a Venn diagram to sort appliances which run on mains electricity, appliances which run on batteries, appliances which use both, and appliances which don’t use electricity.
Some of the things we found which used mains electricity were: a toaster, an oven, a fridge, a television, a kettle and a hair dryer. Some of the things we found which used batteries were: a clock, a torch, a watch and a television remote.
Some things we found which used both mains electricity and batteries were: an iPad, a laptop and a mobile phone.
We found that the following things didn’t use electricity: a can of coke, a Maths book and a table.
Identified the types of energy produced by electrical appliances:
We looked at a variety of electrical appliances and thought about whether they produced heat energy, light energy, sound energy, movement energy or cooling energy.
We identified that a fan produced cooling energy, sound energy and movement energy.
We identified that fridge produced light energy, sound energy and cooling energy.
Ranked and explained what we’d miss without electricity:
We used a diamond shape to show 5 things we’d miss the most without electricity.
We used our scientific vocabulary linked to energy in order to explain why we’d miss the appliance we put at the top. For example, Ella wrote: “I would miss my baby the most because without electricity it wouldn’t be able to produce sound and then I wouldn’t be able to play with it.”
Spotted the appliance which was the odd one out:
We were given 3 electrical appliances (a microwave, an electric toothbrush and a hair dryer) and had to use our scientific thinking to explain which was the odd one out.
Most of us decided that the electrical toothbrush because it doesn’t produce heat energy.
We decided that all 3 appliances move and make sound energy.
Looked at why electricity is important:
We learnt that electricity is useful for lots of things, e.g. it gives us heat, it cools things down, it is used in hospitals to make people better, it keeps our food fresh and it helps us to see when it is dark.
Ways we can stay safe when using electricity:
W e spotted electrical hazards in a picture and watched an animation which taught us that we should only put plugs into electrical sockets, not to pull wires, not to climb trees near power lines and that electricity and water don’t mix!
Increased our understanding of electrical circuits:
We matched up components we’d find in a simple electrical circuit with their jobs and symbols. Then, we used circuit equipment to construct our own circuit to light a bulb, turn a motor, or sound a buzzer.
Using the symbols we had learnt, we were then able to draw and label the circuits we had made.
We learnt that a circuit will only work if it is complete and there is no break in it.
Looked at how electricity reaches our homes:
We went on a trip to Drax Power Station and learnt the process of how electricity is made and how it reaches our homes.
We used the actions we were taught at Drax in order to write an explanation text all about it.

Year 4 trip to Drax Power Station

On Monday 9th October, we went on a trip to Drax Power Station in Selby because we wanted to find out how electricity is generated. We learnt about the different steps which are needed to produce electricity. We learnt lots of new vocabulary, such as: biomass, pulverising mill, cooling towers and generator. We learnt about the job of each piece of equipment which is used in the process. The members of staff at Drax taught us lots of actions to go with each step. We really enjoyed learning the actions and when we got back to school, we used them to produce a piece of work. Also, we showed Mrs Day and she loved hearing about what we had learnt! The tour around the power station was great and we had to wear PPE (Personal Protective Equipment) to stay safe. It was fantastic to see all of the machines in action and to meet some people who work on the power station. Some adjectives we used to describe the trip were: fantastic, splendid and informative. We thoroughly enjoyed the trip and would recommend it to other children. Now, we can all explain how electricity is generated!
