British Science Week 2025
This document outlines a series of engaging, hands-on science activities tailored to different year groups, designed to spark curiosity and deepen scientific understanding. Each activity requires specific resources, which should be gathered in advance to ensure a smooth and successful experience.
Additional Activities: See Them Grow! – A Friendly Competition
To encourage observational skills and an understanding of plant growth, students will participate in a friendly competition:
KS1: Plant mung seeds and observe their growth over time.
KS2: Plant sunflower seeds and track their progress.
Resources Needed: Mung seeds, sunflower seeds, soil, pots, watering cans, and measuring tools.
Reception: Flush it Away – An interactive exploration of where waste goes when we flush.
Resources Needed: Materials for building a simple model of plumbing systems or videos on water and waste systems.
Year 1: The Exploding Lunchbag – A fun and safe chemical reaction demonstrating gas expansion.
Resources Needed: Baking soda, vinegar, plastic lunch bags, and paper towels.
Year 2: Sniffly Tissues – A simple but effective demonstration of how tissues absorb liquid.
Resources Needed: Tissues, water, and different liquids for comparison.
Year 3: Heart Experiment – A hands-on investigation using candy hearts to observe chemical reactions.
Resources Needed: Candy hearts, vinegar, baking soda, and containers.
Year 4: Test Timers – A STEM-based challenge testing reaction times and quick thinking.
Resources Needed: Stopwatch, timers, and various objects for testing reaction time.
Year 5: Tea Bag Rockets – A thrilling demonstration of convection currents and how hot air rises.
Resources Needed: Tea bags, matches, a non-flammable surface, and a fireproof tray.
Year 6: The BIG Fun Science Biscuit Dunking Experiment – A scientific exploration of biscuit absorption and structural integrity.
Resources Needed: Biscuits, cups of liquid (water, milk, etc.), and timers.
These activities provide students with opportunities to develop their inquiry skills, make predictions, test hypotheses, and draw conclusions—all while having fun with science! Be sure to gather the necessary resources in advance to fully engage the students in these hands-on experiments. Links to external resources are provided to support further engagement.
