Kestrels’ latest topic is ‘Changes in Materials’ and this week, they have been finding out what happens when certain chemicals are mixed together in a solution. They were asked to mix water with bicarbonate of soda, vinegar with water and bicarbonate of soda with vinegar.
They learnt that there is a chemical reaction with bicarbonate of soda and vinegar) Hollie certainly did when the balloon exploded from off the top of the test tube!
Today we were going to take part in the Science Week Live Lesson.
Now, you might want to take part in it at home!
Loading...Our new topic of Science this week is ‘Materials and Chemical Changes’. The children started off by having a go at separating a bowl of substances such as: paper clips, sand, sugar and marbles. it was a testing challenge for them but they eventually solved it. They removed the paperclips with a magnet, tipped the remaining substances into a sieve to remove the marbles and then poured the sand and sugar solution through filter paper. The remaining sugar & water solution is sitting by our radiator waiting for the water to evaporate. It was a fabulous lesson and the children have written some very comprehensive instructions to prove their understanding. Well done Kestrels!
Kestrels have continued to study the topic ‘Materials and their properties’ and this week, they had to construct a sandcastle using their knowledge of how sand bridges with water. It took a while to get the consistency right but I’m sure you’ll agree.
Our topic in year 5 is Forces and this week, the children have been learning about water resistance. They predicted whether certain objects would sink or float and then tested their theory to see if they were right.
This week, the focus in science was water resistance and friction. Kestrels carried out a scientific investigation into which material created the most fiction; using a ramp, a weight and a selection of different materials. They recorded their findings and were able to spot scientific anomalies that had occurred whilst carrying out their investigations.
This week’s Science lesson involved the children carrying out scientific enquiry to prove whether a piece of paper that had the largest surface area, would be affected more by air resistance than a smaller folded piece of paper. They worked well in small groups to prove or disprove the theory. Here are the photos!
Kestrels have completed their science topic with a fabulous leaflet detailing all the phases of the moon. They are now able to explain all 8 stages of the moon such as waxing crescent and waning crescent. They have thoroughly enjoyed the Earth & Soace topic and are really looking forward to studying Forces this half term.
Our topic in year 5 this half term is Earth & Space.
This week, we have been looking at theories surrounding The Big Bang. The children carried out an experiment to support their understanding of how our universe has been expanding for billions of years, and is continuing to. They marked their balloons with a serious of letters and measured the points before and after the balloons had been blown up to full size. Their explanations on their findings were very informative. Well done Kestrels!
