On Thursday the 25th of April P5-7 started a science experiment. Miss Dale put us in pairs. I went with Leah. On the white board Miss Dale put up 4 separation experiments for us to choose from. There was: Sieve, filter, dissolve and magnet. Leah and I picked dissolving because we have learned alot about dissolving and it was our favourite.
This is what we dissolved: salt, mud, sand sugar and glue.
First, we got a few cups, spoons and materials. Then we got 250ml of cold water to put with the the materials. We then put them together and stirred them together to see if the material will dissolve in the water. Most of them dissolved like the: glue, sugar and salt but the mud sank to the bottom and the sand hung about in the water. We had to record it on a table, chart or graph; we designed a yes or no table.
What is dissolving?
Dissolving is when something solid breaks down in a liquid.
