Year 5 - Friction
Today, Year 5 explored the mechanics of gears as part of their friction unit. Using cardboard and wooden lollipop sticks, they carefully designed and assembled their own working gear systems, gaining a hands-on understanding of how gears transfer movement and change direction. The children demonstrated great problem-solving skills and creativity, experimenting with different sizes and placements to see how their gears interacted. It was a fantastic opportunity to apply their learning in a practical and engaging way!

Whole School Science Boffin Show- A Whirlwind of Scientific Wonders
The whole school was treated to an unforgettable science show today, delivered by the amazing Science Boffin Katja. Katja started with demonstrating the incredible power of polymers with slush powder, turning liquid into gel. The highlight for many was the "Elephant Toothpaste" experiment, which created a mountain of foam in seconds! This spectacular display showcased an exothermic reaction in a way that truly captured everyone's attention. Katja also explained the essential Fire Triangle (fuel, heat, and oxygen) and demonstrated a controlled fire experiment, teaching us about the science behind combustion. The wonders of air pressure and fluid dynamics were unveiled with a mesmerising demonstration using a hairdryer, balloons, and a foam ball. By generating a powerful column of air, Katja made the objects appear to float, illustrating Bernoulli's principle and leaving students amazed. Naomi, our science Ambassador assisted Katja with this. The latex glove was used in more than one experiment, and was used to show how gases expand. Katja, with Miss Wilkinson's assistance, demonstrated the dramatic effects of gas production using a simple latex glove. As the chemical reaction progressed, the increasing carbon dioxide within the glove caused a noticeable pressure build-up, inflating it and making it firm to the touch. Latex, being inherently limited in its ability to withstand extreme pressure, would stretch beyond its elastic capacity. This continuous stretching, coupled with the weakening effects of the reaction's byproducts and moisture, would eventually lead to the glove becoming brittle and 'crumbling,' visually illustrating the material's breakdown under the stress of the expanding gas.Now, 'Henry' the glove has taken up residence in our school. Science ambassador Noah and Poppy, with a gas blower, demonstrated a captivating toilet roll trick, visually illustrating Bernoulli's principle; by directing a powerful airflow through the center of the suspended toilet roll, they created a region of low pressure, causing the surrounding higher-pressure air to stabilize the roll within the airstream, leaving the children amazed at how the roll appeared to defy gravity. The show sparked a flurry of brilliant questions from our inquisitive students, including Leonora, Elijah, Mason, and Darcy. Their thoughtful inquiries were a testament to their genuine love of learning and the power of hands-on science, truly living life in all its fullness through exploration and discovery. A huge thank you to Science Boffin Katja for bringing science to life in such an engaging and memorable way!
Mad Science After-School Club- Where's the Air?
Our last Science Club session was an exciting exploration of the invisible yet powerful world of air pressure. Our future scientists conducted fascinating experiments that revealed how air behaves in different conditions. They watched in amazement as foam imploded, demonstrating the effects of changing air pressure, and saw marshmallows expand when placed in a vacuum. One of the most exciting moments was watching balloons inflate on their own, involving chemical reactions and pressure differences. By the end of the session, the children gained a new appreciation for the air around us, something we can’t see but is constantly shaping our world in incredible ways.

Year 4's Presentation of Learning- Electricity
This morning our Year 4 class presented their recent learning in Science about Electricity. It was great to see the children projecting their knowledge with clear voices and they gave us several safety reminders such as not overloading sockets, not leaving devices charging overnight and not putting electrical utensils into toasters. Thank you Year 4 for sharing your learning with us and it has been great to see this learning in Science being used in your design and technology unit when making designing and making torches over the last few weeks. We are looking forward to learning even more about Science tomorrow in the Science Boffin Show!
Completed Torches in our Electrical Systems Torch Design Unit
In the second part of our DT lesson, we added the circuits to the casing ( water bottles) and fixed these together securely, ensuring that the switch was still in working order. Throughout this unit the children have worked extremely hard to develop their subject knowledge about electrical systems including identifying electrical products and explaining why they are useful, making a working switch, identifying the features of a torch and creating and designing a functioning torch. Following the testing of each design, we will now move on to evaluating the success of a final product.

Year 5 - Levers and Pulleys
Year 5 explored the fascinating world of levers and pulleys in science! From pushing, pulling and dragging to testing forces in action. The children worked together to investigate how these simple machines make lifting easier. A hands-on lesson filled with curiosity and discovery!
Mad Science Club- Lab Works
Today in Mad Science Club, we became real scientists. The children got to use real lab equipment to stir, swish, and swirl different mixtures. It was a hands-on introduction to laboratory techniques, and everyone participated in the experiments and had great fun.
Year 1 Science and RE- Spotting Signs of Spring (New Life)
This afternoon, Year 1 went to Whitehall Park to look for signs of Spring (new life). They went in search of bird nests, flower buds, flowers, blossom, birds, bees, ladybirds, squirrels and butterflies. They spotted lots of flowers including daffodils, pansies, forget me not and crocus, flower buds, seedlings, birds and were even lucky enough to spot a squirrel.
Reception: Muddy Monday
Today our Reception children explored a different area of Whitehall Park. The children created bug houses and dens together. They also found some sticks and pretended to create fires and also used them as drum sticks. Some of the children tried to climb trees and it was lovely to see how brave they were all being whilst developing their fundamental skills. In addition, the children collectively walked 75km to contribute to our Lent Challenge. Well done!
Reception Firefighter visit
Today the Fire Service visited our Reception classroom to talk about how they help to keep us and the community safe. Lee reminded us that we must check our smoke alarms as they are the best way to keep us safe at home. He also told us about the different ways they help in emergencies, from putting out fires to rescuing trapped animals. He showed us their special uniform and the tools they need to perform their jobs. We then had a look at the fire engine and even experienced a quick shower from the very powerful fire hose. A big thank you to Darwen Fire Service for a brilliant morning.
Year 6 Science Museum
Year 6 also visited the London Science Museum and took part in an interactive gallery called Wonderlab:The Equinor Gallery. The interactive experience ignited their curiosity, fuelled their imagination, and inspired them to see the world around them in new and exciting ways. They enjoyed lots of hands on experiments, live science demonstrations and revealed the beauty of the science and maths that shape our everyday lives. They particularly enjoyed the friction experiment using slides with different surfaces that they could zoom down and see which one had the most friction!

Year 4 - Science: Electrical Circuits and Testing Hypotheses
This week in Year 4, we were hands on with our learning. We began by recapping scientific symbols and then practised drawing scientific diagrams. We then built the circuits we had drawn to test whether they would work. We then made predictions about whether or not different circuits would work and tested them out by building them. There were some super explanations for why certain circuits wouldn’t work, showing a firm understanding of the key components and conditions needed to make a working series circuit.
