We observed what happens when you try to mix water and oil together. We found out that they don’t mix together – the oil just stays on top of the water. This is an example of a hydrophobic mixture. We then added detergent to the mixture and, amazingly, the three ingredients mixed together. The detergent had done its magic and made the water and oil became friends. This is an example of a hydrophillic mixture.
Recently, we have become scientists. We have been finding out all about homogeneous and hetrogeneous mixtures. Basically that means mixtures that cannot be easily separated and mixtures that can be easily separated. We’ve conducted some simple experiments and observed what happened. Amazing! We also used the same ingredients to make some chocolate crackles. Delicious!
