Today we were learning about separating materials. We had to first of all decide what we could use to separate different kinds materials for example we would use a magnet to separate steel and copper nails. Once we looked at how to do this we then got to work making our potions.
After that we were given plastic bottles which Mrs Hay cut in half for us. We then had to put filtering paper inside. Then we were shown the different materials which were: coffee, hama beads, glitter, sand and rice. We had to put some of each material in a small cup and then put some water over the top. We then poured this mixture in to the bottles and waited to see what would happen.
Mostly the water turned brown but some were still quite light at the end. We then took some photos of our finished potions.
We had fun making our potions and putting the mixtures together. I enjoyed waiting to see what colour the water would turn.

Hi Primary 6s,
I really enjoyed reading your blog about how you experimented with separating different materials. What did you learn about the different materials and how they do or don’t separate?

Cool experament P6s maybe the rice did sepurate in the water. Callum
Dear Miss Henderson
We would like to answer your question from last week. We learned that the coffee grains we used dissolved a little bit in the water and coloured the water as it went through the filter. The hama beads just sat in the filter because they are made of plastic and are too big to go through the filter paper. The sand granules are too big and did not go through the filter.
