Year 7 SISKY students investigated the relationship between temperature of solvent (water) and saturation of solute (salt). Students practised 21st Century skills of critical thinking, collaboration, and communication to consider why solutes dissolve quicker and in greater proportion in warmer solvent. Each student played a role in measuring the temperature of the water, recording quantity of salt dissolved, observing saturation, and practising safe laboratory procedures. They enjoyed being able to choose their own groups of partners, and worked well together sharing their thoughts and data. The Year 7s focus upon their practical laboratory skills has helped their confidence and leadership to increase. They are developing into exemplary scientists with the ability to identify opportunities to improve methodology to improve reliability of data. Well done, Year 7!
