Mixture - A substance made by combining/mixing two or more substances together.
Dissolving - When a substance becomes part of a liquid.
Mixing and Dissolving (Experiment)
We started our experiment by getting the equipment we needed.
- A large beaker
- A smaller beaker
- A spatula
- Granulated sugar
We then put 50ml of cold water in the big beaker, we put a 1 spatula of sugar in and started stirring the solution. we timed how long It will take for the sugar to dissolve in the cold water. we started the timer as soon as we put in the sugar and stopped the timer as soon as we don't see any granules of sugar and have made sure the sugar is fully dissolved.
We did the same thing with the hot water with exact same measurements but ended up with completely different results.
We then did the experiment without stirring and got completely different results on how long it took for the sugar to dissolve with the help of stirring and without.
