Chemistry experiment

Today we put two double sided leads on the negative side and the other on the positive side, the negative had a zinc nail on and the other had a copper nail. The zinc nail reacted very well in the solution and we noticed that there was a change in the colour of the metal and gas was released.

Organ Aprons!

Year 4 were put into 4 groups and were given and apron and a bunch of organs! They were required to place the organs in the correct place on the apron which was acting as the inside of our bodies. Once they had completed the and had all organs in place, they were quizzed on the name of each organ they had stuck on. We also had to check if we had put them in the right places!

Year 4 have learnt the names and a few facts about some of the following organs: liver, small and large intestine, kidney, stomach and more!

Model arm

This afternoon year 4 had a look at a model arm to show them how muscles work in our bodies.

We spoke about which muscles we use when we bend our arm as well as how they contract and then go back to their original size.

See what year 4 can remember and ask them these 2 questions:

How many muscles do we have in our body?
What muscle is only joined at one end?

Investigation into muscles and movement

This afternoon year 4 started an investigation around whether the size of muscles affects movement. To do this they are looking at whether people with longer legs can jump further. The children worked in small groups and went outside to perform the investigation. They were each required to measure their leg and perform 2 jumps.

Tomorrow we will be looking at our data and plotting it into a graph. We will then work on evaluating the investigation that we did to see how valid our results actually are.

Comparing different skeletons!

This afternoon year 4 were provided with images of different animal skeletons. Their first job was to go around the room and write down what animal they thought each skeleton belonged to and we then went outside to see the skeletons inside of the animals bodies!

After this the children were asked to compare particular skeletons, discussing the similarities and differences between them.

Presentations on the Earth’s layers

After learning about the Earth’s layers, year 4 were given the task to become an expert on just one of the layers. They spent time with a partner researching on the internet and created a presentation to share with the rest of the class.

The following day the children then presented to their peers. During this time the children were learning about all of the different layers from each other.
