Autumn Term 1 - Burps, Bottoms and Bile

Open wide – let’s take a look inside. We’re on a voyage of discovery to investigate the busy world inside your body. Do you have a toothy grin or a winning smile? Take dental impressions and test the effects of sugary substances on your pearly whites. Follow a tasty morsel as it makes its way through your digestive system, helped by some mouth-watering saliva. And don’t forget the importance of good hygiene at both ends. And whilst we’re talking business, could you recognise an animal just by its poo? Are you brave enough to take the challenge? Make a working model of the digestive system and use it to persuade others to eat healthily. Learn how to look after this marvellous belching, squelching, mixture making machine we call our body.

Week 7

WOW Event

Big Question

PHENOMENAL progress throughout our project! Just look at the difference in understanding of our big question between the very first week and now! So much fantastic learning has taken place and knowledge gained.  

Week 6

Music

We have had great fun this week writing our own song!

 

We used the tune to 'One finger, one thumb, keep moving' and in groups tried to create some lyrics related to the human digestion system.

 

All groups then sang their verses and as a class we chose those that would reinforce the sequence of events that takes place from the mouth to the bottom! Some of them were very silly and made us all laugh! 

The nose smells food,

The nose smells food,

The nose smells food,

Saliva builds in your mouth.

 

Food goes in the mouth,

Food goes in the mouth,

Food goes in the mouth,

Chomp, chomp, chomp!

 

Canines, molars, incisors,

Canines, molars, incisors,

Canines, molars, incisors,

They're all in your mouth.

 

The molars start to grind,

The molars start to grind,

The molars start to grind,

To break down the food.

 

Food goes down the oesophagus,

Food goes down the oesophagus,

Food goes down the oesophagus,

It’s a long journey.

 

The stomach has acid,

The stomach has acid,

The stomach has acid,

To eat bacteria away.

 

The food goes up and down,

The food goes up and down,

The food goes up and down,

Along the intestines.

 

The small intestines are twisty,

The small intestines are twisty,

The small intestines are twisty,

Swoop, swoop, swoop.

 

Faeces builds up the rectum,

Faeces builds up the rectum,

Faeces builds up the rectum,

Ready to go plop, plop, plop!

 

Go to the toilet,

Go to the toilet,

Go to the toilet,

To drop it into the loo!

Week 5

DT

An introduction to sewing, with back stitch being used to add fabric to our t-shirts in our digestive system designs. A super first attempt and excellent use of fabric pens to complete the look!

Homework

Here are some fantastic examples of our homework diagrams and models!

Literacy

The planning of our fantasy story has begun! Watch this space for super narratives of the journey of a piece of food through our digestive system!

DT

Today, we learned how to do a back stitch, which will set us up for our digestive designs! It was great to hear sentences like, "I'm going to ask if I can use my Mum's sewing kit tonight!" and, "I'm going to ask for swing equipment for my birthday!"

Week 4

MFL - Spanish

 

We enjoyed reinforcing our previous learning in Spanish by playing a game this week.

 

Each number on a die corresponded to a response. The person rolling the die used the Spanish phrase for how are you and the next person along replied using the correct phrase.

SPaG

 

After a few weeks learning about vowels and consonants and when to use the indefinite article a or an, we consolidated our learning by producing a poster. This poster had to have the purpose of informing others about when to use the indefinite article a and when to use an. We enjoyed working together to produce attractive and informative posters for our classroom. 

Science

 

We were fascinated in Class 2 when finding out about the digestive systems of a cow, snake and a chicken. We compared them to that of a human, noting similarities and differences.

 

We were shocked to find out that a cow has 3 stomachs!

Computing

 

Flow charts

Having spent the early part of the week learning about the digestive system from start to finish, we used the laptops to create flowcharts on Microsoft Word. We added text, pictures and were also able to alter the colour theme of the flowchart.

Week 3

Kahoot

 

This week we have been busy taking part in a low-stakes quiz to see how much information we have retained from our knowledge organiser. The kahoot quiz was all about teeth.

 

Why don't you have another play of the quiz and see if you can improve your score?

Science

 

What is spit for?

 

We carried out a science investigation to explore how enzymes in our saliva break down starch into sugar. 

 

We chewed crackers for different amounts of time and after spitting the bolus out, we added iodine and water. Iodine turns dark blue/purple when starch is present. We found that the longer the cracker was chewed, the paler the cracker solution was so there was less starch. We concluded that the enzymes in the saliva had broken down the starch to sugar.

 

 

Science

How does spit work?

How do you find out the effect of saliva on food? You chew and spit, of course! A memorable afternoon in Class 2, investigating the effects of saliva on crackers, compared to water. We left them over night to see the differences tomorrow!

We found that the saliva bolus was darker and stickier, whereas the water bolus was drier and flakier. We discovered that this was because the enzymes in the saliva had started to break down the food. The release of sugars also made the saliva bolus smell sweeter!

Science

Which teeth do you need for different foods?

To consolidate the knowledge we have gained about the functions of the different teeth, we investigated the properties of different foods, predicting the teeth we would need to use to eat each of them. We were surprised to find out that the marshmallow needed our canines for ripping a bite off and all of the foods used our premolars and molars to crush and grind.

Week 2

Science

 

We have all been dentists today in Class 2!. 

 

We used dental mirror tools to closely inspect our teeth, examining whether they were milk or adult teeth and whether they were incisors, canines, pre-molars or molars.

Science

 

We had great fun concluding our egg experiment, even though it was rather smelly!

The majority of our predictions were incorrect as we thought that the Coke was going to have the worst effect on our teeth but it was actually the orange juice. Using our prior knowledge from previous investigations, we concluded that the orange juice must contain a lot of acid that attacks the shell.

 

We were all very pleased and reassured when we found out that milk had no effect on the egg shell so we know that it does not harm our teeth when we drink it.

DT

Analysing existing products

On Wednesday, we looked at the packaging for a variety of foods. Thinking about the work we have been doing on teeth and the effect of too much sugar in our diet, we analysed the packaging to see how much sugar is in one portion of each of the foods. 

 

We were surprised to find that the ice cream and fruity cereal bars both contained more sugar than the Haribo sweets per portion, but this facilitated a brilliant discussion about portion sizes. On the box, the suggested portion size for the Haribo was just seven sweets. We all agreed that we would be likely to eat more than seven sweets in one sitting, so concluded that the Haribo actually contained much more sugar than the others and we (Mrs Clarke included!) might need to think a little bit about portion control!

Science

Dental impressions!

We spent some time looking at the different types of teeth humans have, thinking about their shapes, sizes and functions. We then created our own dental impressions and identified the different teeth in our own mouths. It was ideal that some of our class have lost some of their milk teeth recently as the gaps in their impressions made it obvious which teeth were which!

Week 1

Science

 

Eggs, eggs and more eggs!

 

We set up our investigation to see what effect different drinks had on our teeth. We used an egg because we know that an egg shell protects the inside of an egg similarly to enamel protecting our teeth.

 

We made predictions about which drink will have the most effect on the egg and and which will have the least. The majority of us thought that coke would have the most effect as it contains a lot of sugar.

We discussed the need to make our investigation a fair test. We made sure there were equal amounts of liquid in the cups, the eggs were placed in at the same time, we all had the same sized egg and the eggs are going to be kept in the same place.

 

We are so looking forward to seeing whether our predictions are correct next week!

 

Religious Education

 

We reflected on indoor play in Class 2, and thought about the positives and negatives. One of the negatives was not having things to play with. After further exploration, we soon realised that there were lots of things to do but the games and activities were not accessible or in an organised state. 
 

Our task was to sort the resources to create an indoor play box full of interesting and organised games. 
 

This memorable experience was a pathway into learning about the Buddhist festival of Kathina which takes place after the rainy season, where in some countries they have about 3 months of heavy rain. 
 

Even though we are very proud of our new indoor play box, most of us were not keen on having indoor play for 3 months straight! 

 

 

Science

Effective teeth brushing

We had so much fun investigating the plaque left on our teeth after brushing, using plaque-disclosing tablets! So many of our 5Rs were needed for this afternoon's learning: Risk-taking because it was new and some  of us were a little bit nervous; Relationships because we had to work together to see the plaque on our teeth and share the resources; Reflecting because we had to look at our tooth brushing habits and think of ways we could improve and be more thorough. We all found ways we could improve our oral hygiene and had lots of fun in the process!

DT

Healthy recipes

We had a very busy afternoon! In small groups, we followed different recipes to make healthy lunch box ideas. We talked about the different ingredients, identifying the healthy ones and the ones we should be eating in moderation (e.g. cheese and mayonnaise). We had a very successful afternoon, making cheesy coleslaw pittas, hummus salad wraps and a tasty bean and tuna salad!

 

The recipes are below if you want to give them a try at home!

Computing

We used 'Paint' to practise editing our images today, thinking about why we need to look after our teeth and what might happen if we don't!

Still image for this video

We had a great week investigating the effect of fluoride toothpaste on our teeth! We used eggs to represent our teeth and learned that the shell protected the inner egg in a similar way to enamel protecting our teeth. We submerged two eggs in vinegar (representing the acid in our mouths from sugary foods); one had been coated in fluoride toothpaste and the other was plain. 

 

Unsurprisingly, we discovered that the egg that had been coated in fluoride toothpaste was in a much better condition than the plain egg after 24 hours in the vinegar. However, we were surprised to discover that the plain egg's shell had gone so soft that the egg actually bounced!

 

This was a great way of reinforcing the importance of good oral hygiene after Mrs Knight's National Smile Week Assembly earlier in the term. It was also a really fun way of launching our new project!
