Floating Colours lab report

Conclusions:

1. What happened to the food colouring when you added it to the oil? Did this step result in a mechanical mixture or a solution?

2. When you pushed the food colouring through the oil and into the water, did it create a mechanical mixture or a solution? How were the results different from when we mixed food colouring with a beaker of water (without the oil)?

3. What happened to your mixture when you added dish detergent? Why do you think this happened (hint: think of what happens when you wash dishes)?

Remember, to access your header/footer (for your name), click "View" and then "Header and Footer." To access your bullets (for the Materials section), click on "Format" and then "Bullets and Numbering." To create your table, click on "Table" and then "Insert table." Your table should be virtually identical to the table in which we recorded our observations last class - 4 columns, 10 rows. Be mindful of the justification and bold/italics of the headings.

Remember also to be consistent with your formatting - ie. putting a blank line (enter) after each heading, staying consistent with your bold, underline, italics, etc. Your document should look neat and organized when you are finished!

We will have at least 2 periods to work on this lab report (after today), so please
