Science – Exploring Dissolving

 P5-7 have enjoyed exploring the scientific process of dissolving this week in our co-operative groups. As a team, we discussed, designed and carried out our own dissolving experiments. Some materials we explored included coffee, salt, sugar, chalk, rice and chocolate powder! Our experiments allowed us to discover the impact that stirring, volume of water, temperature of water and weight of the solute had on the speed of dissolving. We used the class i-pads as timers to ensure accurate results and compared our predictions to our actual results.

We evaluated each others experiments to ensure that each designed experiment was fair and we enjoyed discussing the outcome of each experiment.

During our experiments we began to discuss the process of separation and filtration. Our next Science lesson will focus on these topics.

We enjoyed trying out the safety goggles!
