How is food digested?
Class 3 have been getting messy, investigating digestion! We saw the whole process happen - right in the classroom!
Starting with a banana and spread sandwich, we watched as some of the children cut it up using a knife to represent the incisors! Next, we added some "saliva" (bubbly water!) to start breaking down the food. Using a potato masher, we could see how the molars grind the food into a mushy pulp.
Now we had to transfer the food into the "stomach". We did this by taking spoonfuls of pulped food at a time - this showed us how the oesophagus squeezes the food down. When the food was all in the "stomach", we mixed it together with some stomach acid (lemon juice!), digestive enzymes (tomato sauce!) and bile from the liver (yoghurt!)
To represent the food entering the intestines, we spooned the "food" into a pair of tights. We could see this would take time as it was a lot narrower than the stomach! Once in the "intestines", we were able to see the liquid coming out out, ready to be taken elsewhere.
Finally, when all the liquid had been removed, we cut a hole in the tights and pushed the "waste" out. (You can guess what this looked like!!!) Needless to say, lots of children volunteered for this part!!
How far does our food travel?
Have you ever wondered how far the journey of our food is, inside our bodies? Class 3 have...and it's further than you'd think! Today, we watched a video about the journey of our food and, afterwards, each group were given a part of the digestive system to measure out. Using string, they measured the length of their individual part (the most surprising being the small intestine which measures a whopping 6m approximately!!!) Once all the individual parts had been measured, we combined the whole digestive system together, measuring over 8m!!
"Where does it all fit?" they wondered, looking down at their tummies!
What a busy term we've had: World Book Day, Science Week, Easter preparations alongside some fantastic learning in class (and even a letter from a certain well-loved author!)
Have a fantastic Easter and enjoy a well-earned break! Here's a little taster of our Spring term activities...
DT - Stone Henge Models
We are very proud of our wooden Stone Henge models! After planning our design, we had to carefully measure, cut, sand, glue, paint and finally add finer details to make our models attractive and interesting.
What do you think?
Stone Age Art
Class 3 have been getting messy making Stone Age artwork! We learnt that, during prehistoric times, humans were actually very creative and cave paintings were an important part of Stone Age culture. Because shops didn't exist, people had to use natural resources to create paints. So we went outside to see what we could find and try to make it into something we could paint with!!!
Class 3's Tooth Eggs-periment!!
We have been wondering what sugary drinks can do to our teeth. We know it is bad for them but what does it actually do? Of course, we can't take our teeth out and start experimenting on them so, in this investigation, we used eggs as they have a similar coating on their shells as the enamel on our teeth.
In groups, Class 3 decided which test liquid they would like to try from orange juice, cherryade and vinegar. To make it a fair test, they also used a control egg which was placed in water. Both eggs had the same amount of liquid, were left for the same amount of time and were similar in shape and size.
The results were quite shocking!!!!
Class 3's Mammoth Adventure to Ipswich Museum
We had a wonderful visit to Ipswich Museum yesterday! We loved the mammoth, which greeted us as we came in (designed by the creator of Chewbacca's costume!!) and were surrounded by animals and artefacts from the Stone Age. We got to handle real stone tools and weapons and understand what life was like for our hunter-gatherer ancestors. We had to think about how we would survive and plan our food, shelter, weapons and skills!
After lunch, we created neolithic coil clay pots and visited the other animals in the exhibition. Upstairs, we saw the bird gallery- we couldn't believe how big some of them were! In the Geology room, we saw a whale skull which had been found on the River Orwell and lots of amazing fossils!
It is such a wonderful museum and totally free to the public so why not visit again and have your own personal Class 3 tour guide!
Fun with Fractions!!!
We have had a lovely time in Class 3 this week, playing fraction games and activities to help us learn more about parts and wholes. We have made lots of discoveries and the children have loved the challenges. Yesterday's Think Link Thursday was a challenge to answer some reasoning problems with our Think Link, involving visual fractions. Today's Friday table challenge involved a competition to see which table could complete the fraction dominoes first! Well done to the Tuesdays who were the champions!
Maybe you'll be able to find some more fractions in the real world when you are out and about. Thinking about them in terms or parts and wholes is a great way to understand what the fraction actually represents.
Science - Electricity
Class 3 have been having fun investigating 'conductors' and 'insulators' in our Science work. They were very confused initially when I gave them tin foil instead of cables to light their bulbs but, sure enough, it worked - as Chloe and Matilda found out. We talked about why the foil allowed the electricity to travel and the children predicted what items around the classroom might also do the same job! They were amazed to find scissors, paper clips, keys and even drawing pins all conducted the electricity!
Try asking your children if they can remember what the terms "conductor" and "insulator" mean. Can they think of any examples?
Remember children - electricity is very dangerous and the circuits we made at school used very low voltage so they were safe!
Anti-Bullying Week 2018
Last week, it was Anti-Bullying week and we spent the whole week celebrating our differences, starting with our odd socks on Monday! We identified what makes us and each other special and wrote messages for each other to share our favourite things about them. We learnt to understand what it means to be a 'perpetrator', 'victim' and 'bystander' and learnt that bullying behaviour is about an imbalance of power. We made and shared our posters with anti-bullying messages, using our spelling words. During the week, KS2 also took part in rewriting the anti-bullying policy with Mrs. Thomas. We finished be writing a class story called "Odd Panda Out", inspired by our class book "Odd Dog Out".
I was really proud and impressed with the mature attitudes shown in Class 3 during the week.
Posting Letters to Anthony Browne!
We were so lucky in Class 3 today to have both Sally Croft and Rev. Liz show us around our church. In our topic Here, There and Everywhere, we have been focussing on the local area and have linked this with our RE work on Christianity. Over the past few weeks, we have been learning about the features of a church and the children were armed with their questions today as we headed to find out more.
Sally had designed a really fun activity which had involved labelling the parts of the church with their correct names (this even involved labeling Liz as the 'priest'!) Then we talked further about all the parts and their role in the church. The children knew lots and asked some fantastic questions, eager to learn more!
After the visit, Class 3 led the assembly at school, teaching the other children about what they'd learnt. They did a supper job and were complimented on their enthusiasm, behaviour and their confidence in talking to the rest of the school. I was very proud of them all!
Class 3, I wonder if you can remember what a "hassock" is?
In Class 3, we have been doing an author study on Anthony Browne. As well as using his books for our literacy work, we have also been looking at his wonderful illustrations for our artwork. We used his book "Willy the Dreamer" to help us sketch facial expressions. His characters are always so full of personality - we think ours are too!!
