Robin Class - Friday 22nd May
It’s the last day before half-term and I feel like it’s absolutely flown by. As it is Friday you may answer the register in any way you choose – so long as it isn’t rude. Mr Savage might walk in the door at any moment and I don’t want him to catch you saying rude things back to me.
You have a week’s holiday next week and after that we are going to continue as we have been this half-term. I’m really pleased with all of the effort you’ve been putting in, as is shown by the learning I am emailed every week. In fact, Robin Class has had wonderful engagement so far with the activities I’ve been setting which makes me very proud. We still have lots to cover next half-term including computing, art, design & technology, RE, history and of course we need to finish our science topic of animals including humans.
Remember to please check that you have permission from your parents before using the internet. If you need to access our previous days' learning, please follow the links at the bottom of the page.
Good luck Robins.
Science/ Design & Technology (DT)
As for our science work, and to finish off this half-term in style, today I would like you to make a model of the human digestive system.
This could get a little bit messy so you might want to do this in the kitchen or even outside. To do this you will need these pieces of equipment:
For the journey from Mouth to Stomach:
- A knife and fork
- A plate for cutting up your bread
- A zip lock bag, sealy bag or similar
- Around 2 slices of bread
- Toilet or tissue paper tube
- Warm water
For the journey from Stomach to rectum:
- A Balloon
- A Needle
- A Large bowl
1. Using the knife and fork cut the bread into tiny pieces. This is like the way your teeth grind food into small pieces in your mouth. You could add a tiny bit of water to help. This is like saliva being added to food in your mouth.
2. Carefully put the bread into the tube with a sealy bag underneath. This is the oesophagus which takes food to the stomach. Squash and squeeze the food down to the stomach just like it would do in your own body.
3. Once you’ve squeezed it into the bag which is your stomach, add some water into the bag. This is special juice that lives in our stomachs and helps us take the goodness out of food.
4. Seal the bag and squash and squeeze it with your hands. This is the muscles in your stomach moving the food and liquid all together.
5. Watch what happens to the bread. All of the good bits of the food are now broken down and can be used by the body.
6. Blow up and then let down a big balloon. This is your small intestine which breaks down food from your stomach even further. Carefully pour the bread mixture into the balloon using a funnel, seal the top of the balloon and squeeze.
7. Poke some pin-sized holes into the sides of the balloon. This is now your large intestine which has tiny holes in the sides to let all the water out. Very carefully squeeze the water out of the large intestine into a large bowl. Be gentle; you don’t want it to burst.
8. All the mush that is left is now going into the rectum. It is all waste as all of the water and goodness has now been taken out and we get rid of the waste when we go to the toilet. Cut a hole in the end of the balloon and squeeze the mush out. This whole process is what our bodies do to everything we eat and drink.
I hope you didn’t get too messy. I would love to see some photos of your experiment put on the school’s Twitter Page. Either ask an adult to post them directly or email through to Ms Griffin on firstname.lastname@example.org and I’m sure she would be happy posting them for you.
It is Friday so you will need to be tested on your spelling words. Ask someone in your house to test you. Even better if you write each word out in a sentence.
As it is half-term next week I will be giving you spelling words to learn below:
|Year 4 Words||Year 3 Words||Year 2 Words|
I will also attach the PowerPoints for you to do on your week off. I’ve been through the presentations and they all have some great fun games to play. Don’t do your spellings today, save them until next week when you have a spare moment or two.
No big maths today as it is Friday and you’ve already got an awful lot to do. Please practice your times tables on TT Rockstars. If you play for 20 minutes, can you move up 5 levels? Remember to always set it to 1 minute.
If you’re maxed out at level 420, then please, please, please go on Sumdog. I have also found some fun extra maths activities which you’ll find at the bottom of the page.
Optional Additional Activities
- Using the image above, how many different ways can you find of writing one half?
- From the picture, what equivalent fractions for one third can you find?
- Again, using the image of the fraction wall, how else could you write three quarters?
- Can you find any "rules" for working out equivalent fractions?
Below is a PDF of this picture if you would like to print it out.
Mandeep's watch loses two minutes every hour.
Adam's watch gains one minute every hour.
They both set their watches from the radio at 6:00 a.m. then start their journeys to the airport. When they arrive (at the same time) their watches are 10 minutes apart.
At what time (the real time) did they arrive at the airport?
