Explosive Science: States of Matter Reaction

Year 5 experienced an explosive demonstration of changing states of matter this week! We explored the surprising chemical reaction between humble bicarbonate of soda (a solid) and different types of vinegar (a liquid). The class learned that mixing them instantly produces a brand new substance—a gas, carbon dioxide. We observed the dramatic fizzing and foaming as the gas rapidly escaped, demonstrating a solid and liquid reacting to form a gas.

We then investigated how changing the type of vinegar (like white, malt, or apple cider) affected the reaction rate and fizz intensity. This hands-on investigation was a foamy, fun, and memorable way to see the three states of matter—solid, liquid, and gas—in dynamic action!

Super Soakers: Y5 Investigates Absorbency

Year 5 became material scientists this week for a fantastic and hands-on investigation into absorbency! Our mission was to discover which everyday materials could soak up the most liquid. Working in teams, we tested four materials—paper towels, test tubes, straws, and fabric—using a fair test setup.

We used straws to carefully measure the exact volume of water absorbed by each sample. The class learned all about variables, ensuring that the size of the material and the testing time were kept the same. The results were thrilling! We observed significant differences, with the paper towels proving to be the ultimate super soaker. This experiment taught us about the real-world applications of material properties, turning us all into experts on tackling spills!

Royal Armouries

A Knight to Remember: Y5 at the Royal Armories

Year 5 had an absolutely thrilling day at the Royal Armories in Leeds! We stepped back in time to explore magnificent collections of armor, shields, and ancient weapons. The highlight was definitely seeing the full-sized jousting figures and the shining suits of armor worn by knights centuries ago.

We saw huge cannons and learned about battlefield tactics. It was incredible to think about the history held in those objects. We particularly enjoyed the live demonstration where an expert showed us greek weapons and armor. It was an exciting, hands-on history lesson that brought the medieval period to life!

Groovy Greeks

Hi Everyone,

First blog post of 5A!

As part of our unit on the ancient Greeks, the children have been studying various historical sources and have tried to determine which sources are primary, which are secondary and why this is important in studying history. The children then conducted a ‘silent debate’ where they went around the class in groups to different stations to record their thoughts and ideas, building on other peoples.
