Year 4 Weather Reports

When we looked at different countries around the world we looked at how their weather can be different to ours.

We watched weather reports and then researched a particular country to find out what the weather was like and if it was normal for that time of year.

Here are our weather reports:

Year 4 drama: freeze frames

As part of our topic we have been looking at the country Brazil. To help us understand the life of some children we have read a story about a boy called Pele who lives in a favela in Rio. He has to make some choices along the way about whether he should be selling papayas to help his family get money or join in a football game as it’s his dream to be a professional footballer.

We spent some time weighing up Pele’s choices and found it was difficult to decide especially as we were able to give reasons for both choices.

At one point in the story he upsets an older boy called Dengar who also lives in the favela. Pele is warned to not be out in the favela after dark or he will get into trouble.

We had to imagine that Pele was coming home to the favela in the dark after selling his papayas when he was met by Dengar and his gang.

We freeze framed what we thought might happen to Pele:

Unfortunately we were concerned that Pele may have had a negative experience with Dengar and his gang. This led us on to discussions about who to speak to if we need help in any situation.

We thought carefully about how Pele might have felt during this story and used those emotions to help us write our own stories about children living in Brazil.

Well done Year 4 for thinking so maturely and carefully about other people’s feelings and experiences.

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…

How we know that we breathe out carbon dioxide:

How our muscles work:

How we use energy:

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!
