Year 4 visit @wethecurious_

On Friday Years 3 to 6 visited We The Curious in Bristol. We had a brilliant time there and really enjoyed ourselves!

Year 3 and 4 completed a workshop on the digestive system. We learnt the different organs that are in our bodies to help us digest our food and the job that each part of the digestive system plays. We had to play the part of our mouth, stomach and intestines to digest our ‘food’ and get rid of the waste product poo.

We also completed an experiment making different toothpastes. We had cards with different recipes that included bicarbonate of soda, glycerin, peppermint extract and sand. Our recipes didn’t include all of the ingredients and some of us could brush our ‘teeth’ with toothbrushes but some people had to use our fingers. We found that brushing our teeth with toothbrushes was better and some ingredients were more successful. As it’s ‘Science Week’ we’re going to look at this in more detail this week so come back and see how we get on!

 

In the afternoon we went to a ‘How your body works’ show which had experiments and demonstrations showing how different things in our body work. Take a look at the videos below to find out more…

A very big thank you to We The Curious for our exciting day on Friday, we loved exploring the exhibitions and learning new things in our workshops and shows!

Year 4 dissect hearts

Today we were looking at the heart and we found our way in through the aorta and the pulmonary artery. The hearts were a different shape to what some of us thought they would be. We felt the hearts and they are made of tissue and muscle. We could see the blood vessels. There was some fat on the outside of the heart because we need some fat in our bodies to keep our organs warm and protect them.

Before we cut them we had to feel them to see which side was the thin side and which was thicker. The thicker side was the ventricle muscle. When we cut the hearts open we could see the blood vessels, the 4 chambers and what we think was the aortic valve. We put our fingers through the aorta and pulmonary artery to see which chamber they went into.

Here’s what we thought about today’s dissection:

It was disgusting but extraordinary to see what was inside our heart.

It was interesting to see what the chambers in our heart look like.

I liked it because I found out that one side of your heart is thinner than the other.

The best part for me was feeling the heart because it felt firm, fleshy, strong and slimy.

I liked the part when we saw all the blood vessels because it was satisfying to see what they looked like.

I expected the heart to be a bit bigger because it pumps in your body.

I didn’t know that the fat around the heart was so hard.

It’s interesting how the heart works hard every day and I saw how the blood gets into the chambers.

I enjoyed looking inside the heart because it was amazing to see lots of blood vessels.

I didn’t like the bit when I touched the heart and it was extremely light.

Exploring lungs in Year 4

Today we found out how the lungs work. We looked at some lambs lungs with Year 3. We had to put on aprons and gloves and we worked in groups.

To see how the lungs inflate we used a balloon pump to blow air into the lungs. We put the balloon pump into the trachea and we saw the lungs inflate with air. We were surprised how big the lungs were when they were inflated and how small they went when they were deflated.

One group could clearly see the one of the bronchioles and it looked like a tree. We cut the lungs open and we could see the tubes that lead to the air sacs (alveoli). Another group was able to put their stick through the trachea and found their way into the lungs.

The lungs felt wet, slimy, cold, squishy, and spongy. The trachea felt harder than the lungs and they felt bumpy. On the back of the lungs we could see the tissue that would connect the lungs to other organs.

We all joined in exploring the lungs and here is what we thought:

I thought exploring the lungs was disgusting but okay.

I thought it was weird but awesome because we can see what lungs actually look like.  It was amazing to see how our lungs work hard every day.

It was inspiring to see how the lungs would work. I thought the lungs would be small but today I found out that the lungs were really big to pump a lot of oxygen around your body. I learnt today that our lungs need a lot of oxygen from the air.

It was interesting feeling the lungs because it felt smooth in some places and bumpy in other parts.

It was interesting looking at what’s inside us. I liked it when I put the stick through the trachea into the lungs.

It was interesting how squishy our lungs are.

It was interesting when you blow the lungs up, they change colour. It is satisfying to see how your lungs breathe.

It was amazing to see how our lungs would work.

It was interesting because I saw the holes in the lungs.

It was strange that only one of the lungs inflated.

The bronchioles looked a bit weird but I am a bit squeamish.

I enjoyed touching the lungs because they felt funny and squishy.

Victorian Christmas Decorations

As part of our topic we learned about decorations that Victorians would have used for Christmas and what traditions we have thanks to the Victorians.

On our trip to Cardiff Castle we made a pine cone decoration and a Victorian style Christmas card. We found out that they would make peg dolls to hang on the tree as well as put nuts in bags as little presents. We also found out that Christmas crackers were invented thanks to Tom Smith during the Victorian times.

We decided to make some of these decorations ourselves to experience what it might be like for Victorians to make their own decorations rather than buying them from a shop like most of us do today. We had a great time making our decorations and we’re so proud of what we’ve produced.

This is the end of our Victorian topic. We have loved learning about the Victorians and we have found out so much about them. We have a lot to thank the Victorians for, especially for some of their wonderful inventions and Christmas trees!

William Morris inspires Year 4

As part of our topic on the Victorians we have looked at the artist William Morris. We took his inspiration, which was nature, and tried to create our own repeating patterns.

At first we tried to draw our own repeating patterns but we did find it was tricky to make them match exactly.

 

Then we tried to paint our our individual patterns:

We really enjoyed making our patterns and they looked very effective!

We discussed how we really had to concentrate to ensure that each repeat was identical to the one before. We looked at how printing machines were developed through the Victorian era and wondered if this would make a more consistent pattern. In order to try this out for ourselves we went onto Purple Mash to create our own designs.

This was a really interesting way of creating repeating patterns, we found it hard to choose our favourites.

We then wanted to make our own painted repeating patterns and we decided to use a tile to do this. We carved a picture into a polystyrene tile, rolled paint onto the tile and pressed it onto a large piece of paper. We continued this until we had covered our paper in the repeating pattern. This was a really fun lesson and here are our finished pieces of work, including a close up of each pattern.

Thank you William Morris for your inspiration!

A Victorian lesson at St Fagans – Years 3 and 4


Years 3 and 4 went to St Fagans for a Victorian school lesson. We were taught by Mr Evans who made us do handwriting, history, reading and recite our times tables. We all had to write with our right hand, even the children who normally use their left hand! We were surprised how different our lessons are to the Victorian lessons and we really felt like Victorian children.

Take a look at our Victorian lesson in the slideshow below:

As part of the history lesson we had to recite a poem about the kings and queens of Britain. We tried really hard to speak clearly and recite it correctly:

 

Here is Nivas’ recount of our trip to the Victorian school:

On Friday we went to a Victorian school at St Fagans. We learned what Victorian schools were like. On the trip we went inside the building and if you talk or behave badly you will be caned. In the playground boys play on one side and girls the other side. In Victorian schools you must write with your right hand and if you speak Welsh you will wear a necklace and your job is to catch another person who speak Welsh and if you do you tell the teacher and they have to wear it and at the end of the class whoever has the necklace will be caned.

When we entered the room we were dressed as a Victorian school child. Victorian school children learnt handwriting, maths and reading poems and history. When a grownups enters the room all the children must stand and if you don’t you will be caned. If you write with your left you will get something to stop you writing with your left hand.

For lunch you will go home and when the teacher rings the bell that means you have ten minutes to get ready to come back to school and if your late you will get caned.The boys learned drawing and girls learned sewing and cooking. In Victorian schools you have to be five to start and 13 to end school. The bigger children sat at bigger desks and tiny children sat in tiny desks. Victorian teachers were very strict. We had to learn handwriting and you must not fidget or talk. Sometimes if you were very naughty and you would have to write lines 100 times or more. I thought it was very bad and I would not like to be a Victorian.
