This week as part of Year 3’s Dimensions topic, Athens v Sparta, the children have put their science hats on to investigate floating and sinking.
They predicted which materials would float or sink and they discussed how density effects objects. Today they had 3 attempts to make their plasticine ‘boat’ float. The children had lots of fun manipulating the plasticine, problem solving and finally figuring out how to make their boat float by equally distributing the mass into a boat shape.
As part of Year 3’s National Curriculum Essentials Science topic, May the Force be With You, they have been learning about magnets.
Today they were tasked with finding the magnetic items in our classroom by using a magnet and placing it over a selection of objects, just like in a scrapyard. If the items were magnetic they would be attracted to the magnet.
They had to sort the items into magnetic and non-magnetic. They discovered that all of the magnetic items were made from metal, however not all metals are magnetic as the pencil sharpener blade was magnetic, but the rest of the object wasn’t!
As part of Year 3’s Dimensions topic, ‘May the Force be With You’, they have been investigating the force, gravity.
They used tennis balls and examined what happened when they threw the ball upwards in the air, they noticed that gravity pulled it straight back down again.
Class 7 enjoyed investigating which materials would be picked up by a magnet in a Scrapyard Challenge this afternoon.
The children held a magnet over a pile of different materials and recorded which of them were picked up by the magnet. They predicted that all of the metals would be attracted to the magnet, however, found this to not be the case after trying with a copper coin! We now know that not all metals are magnetic.
This week in Science Year 3 have been investigating how rocks change over time as part of their Learning Challenge Question: What can rocks tell us about the way the Earth was formed?
They agreed that rocks don’t change massively to the naked eye, however we know that they must change over time somehow!
We worked in small groups to conduct an experiment. We chose a rock, and placed it inside a jar with 100ml of water. We shook the jar to the count of 100, then filtered out the water through filter paper to see what was left behind.
Once all of the water filtered through we noticed there was some debris left in the filter paper. Some of us said that this looked like sand! It was clear that the rocks knocking together had made small fragments break off.
Super work, Year 3!
On Tuesday 10th November we celebrated World Science Day at West Boldon! Every class looked at a famous scientist linked to their topic.
They created a fossil jar whereby jelly represented the soil and sweets represented the animal remains. Each day this week they will add a new layer of jelly to the jar representing how soil layers occur over time. They talked about how these fossils form and also made a zigzag book!
Year 6 looked at Charles Darwin to link to their topic on Evolution. They all created a factfile about him explaining why he is so important in his field.
What wonderful scientists we have at West Boldon!
This week in Science we began learning about what makes Usain Bolt so quick as part of our Animals Including Humans topic.
We learned that to run fast we need really strong muscles and to be very physically fit. We discovered that muscles work in pairs to contract and relax, to enable our bodies to move. We also learned about two specific type of joint found in the human body; the ball and socket joint, and the hinge joint.
We then went outside with the iPads and struck a pose, then in small groups we labelled each of the muscles and joints we had used using the Seesaw app.
Take a look at our awesome work below.
In Science in Year 3 we are learning about the human body. Our Learning Challenge question is ‘How does Usain Bolt move so quickly?’
As part of this, we all measured and ran 100m across the school field. The fastest 4 times were recorded and compared against Usain Bolt’s world record winning time of 9 seconds.
Over the coming weeks we will discuss what makes him such a fast runner, learning about bones, muscles, food and nutrition. Take a look at some of our fabulous work!
This week in science, Year 3 have been investigating which magnets are the strongest. We know it’s not just about the size of the magnet, but the strength of a magnet’s magnetic field. We tested out 5 different magnets to see how many paper clips would be attracted to each. Here is a pictogram of our results:
