Year 5 science

Year 5 science - WW2 Focus

• How do gas masks work? We learned a how mixtures can be separated through sieving and filtering.
• How was powdered egg used in WW2? We learned that some materials dissolve in liquids to form a solution and how we can recover a substance by evaporation.
• What is the best fabric for a WW2 soldier’s coat? How does this compare with modern fabrics? We sorted different fabrics according to different properties.
• Which fabric curtains would be best to have during the Blitz? We learned about irreversible changes and compared new and old fabrics
• Which phase of the Moon would be best for the Normandy landings in 1940? We modelled the different phases of the Moon and found out which would provide the most light for soldiers to see.
• Can the English tanks and heavy equipment be brought onto the Normandy beaches? We planned an investigation to compare impact of weights on different sands.

Also, Year 5 have taken part in a BBC Terrific Scientific investigation about feet.
Scientists at the University of Kent are researching whether the terrain we walk on will affect our foot flexibility.
We developed our investigative skills – measuring accurately and gathering data to calculate how flexible our feet are.
Dr Trew sent our data to BBC Terrific Scientific and you can see this on the BBC interactive map at
• 5SD is registered as Class 3 on the map.
• 5ZC is registered as Class 4 on the map.
For homework, we also measured the flexibility of an adult’s foot. We sent this extra data to BBC Terrific Scientific and they have written back to us!
