Magnetic field

This afternoon in Science, the Bluebirds in Year3 were using magnets. We were learning about the magnetic force around a magnet called a magnetic field. We were investigating different items, seeing if they were attracted to the magnet or not.

First, we made a prediction.

Then we tested each item with a large magnet!

We ticked our predictions if we had made a correct guess.

We also had a magnet each and were given the time to play and investigate a metal paper clip and iron filings at our tables.

Investigating friction of different surfaces

Yesterday afternoon during Science, the Bluebirds in Year 3 were doing a Science experiment. We were investigating the friction of different surfaces. We did this by raising a platform in 5cm gaps to see when a toy car would start rolling down the ramp. The surfaces we measured were, wood, carpet, bubble wrap, sandpaper and sponge. We all made a prediction before the experiment and recorded our measurements during the experiment. We were working in groups and showing the behaviour for learning of ‘team work.’

Forces

This afternoon, the Bluebirds in Year 3 started a new topic in Science, forces. We watched a video of lots of different clips showing pulling and pushing, we discussed which force was being shown in each short clip.

Our challenge was to think of different sports that involve a pull or a push force.

Soil collage

This afternoon, the Bluebirds in Year 3 were making collages of the layers in soil. We had the layers on the board to remind us about what they were and talked about how we could create the layers using coloured paper and tissue paper. The Bluebirds worked in pairs and could choose their own resources. Mrs Moore and Miss Knapman were looking for the ‘team work’ behaviour for learning for silver and gold cards this afternoon.

There was some fantastic team work! We saw children working together, talking to each other, listening to each other and planning their collage really well. Excellent work Bluebirds!

Movement of the Moon!

Bluebirds were very interested in learning all about the moon today. They discovered it does not give out moon light but reflects sunlight. They acted out how the moon moves using equipment besides watching film animations. They realised that the moon is present all the time and does not “come out” at night. Mrs Parry and Ryan had both noticed the moon one morning last week, before school!

Charlie – I’ve learnt there are new names for different parts of the moon such as new moon, half moon and the dark/far side!
Ryan – The Moon orbits the Earth.
Havanah – Other planets have got different moons.
Paige – When there is less of the moon it is called waning.
Ibrahim – The Moon spins anti-clockwise.
Dewha – When there is more of the moon it’s called waxing.

Day and Night

Bluebirds have been learning about how the earth moves to find out what causes day and night time. They remembered the Equator was the hottest part of Earth from their Year 2 lessons!

Amaya – The Earth orbits the sun.
Ryan – It takes 24 hours for Earth to make one full turn.
Ava – The side of the earth facing the sun has daytime. The opposite side is dark so it is their night time.

The children set up an experiment to investigate which country was in darkness (having night time), whilst another was experiencing day time. The children led the experiment by selecting countries they wanted to find out more about. Some chose countries they had visited on holiday whilst others selected countries they would like to visit!

Some children linked this with knowledge they have gained through our Guided Reading sessions. Everyone is currently reading non-fiction books covering light, night and day, the seasons and life in space. Well done Bluebirds!

What happens when you eat?

On Monday, Bluebirds had a piece of cracker in their mouth but were not allowed to chew or swallow it. They had to wait and think about what was happening in their mouths. After a while, they noticed their mouths began to water as saliva and (spit) was produced! Some of the children had eaten Shepherd’s Pie, chips and peas and wanted to see an experiment to find out what happened!

The children got to work, mashing up the mixture of food as the tongue/teeth/saliva and stomach would do. Milk and coke was added too – thirsty work! Afterwards, the “digested food” mixture was poured into the leg of a pair of tights. Strong stomached children then squeezed the mixture along the “intestines” to understand how the muscles contract to move the mixture along. Finally, the “faeces” left the intestines and arrived in the “toilet!”

This interactive lesson was really effective in helping the children to understand how our digestive system works. After the food is chewed with saliva and made into a ball with the tongue, it is swallowed and pushed down the oesophagus until it reaches the stomach. Here the food is broken down with more enzyme juices until it is a creamy pulp. The food enters the small intestine where nutrients and vitamins are absorbed and distributed into the bloodstream whilst the waste (faeces) continues into the large intestine until it reaches the rectum and exits from the anus.

Leo – I found out that acid breaks your food down once it reaches the stomach.
Jani – Your big intestines are like muscles that push your food along.
Ke Xin – I found out once you’ve eaten, the food stays in your stomach for 2 1/2 – 3 hours.
Amelia – I was amazed at how long are intestines are! Mrs Parry and Mrs Johnson showed us with a length of string. It nearly went across the whole classroom! I also learnt the proper name for poo (faeces)!
