This week, Primary 5 were learning about dissolving.
We learned that dissolving meant that the particles of one material mixed with a liquid to create a ‘solution’. This means that the material is ‘soluble’. If the particles cannot mix with a liquid, it is ‘insoluble’.
We tested different materials to see if they were soluble or insoluble. We use the same measure and temperature of water to make sure it was a fair test.
We found that chalk and sand were insoluble. Flour, coffee and salt were soluble. We were unsure about gravy as some of it dissolved, but not all. We wonder if the temperature of the water would make a difference – what do you think?
Until next time…
Primary 5 & Miss M 🙂
