Problem; How small is 1 part per million? What will happen to our pure food coloring when we dilute it to 1 part per million using water?
What could my hypothesis be?
What do you think when the food coloring is diluted to 1 part per million?
What do you think will happen?
To determine how small 1 part per million (ppm) is, we need to calculate it.
1 ppm means 1 part out of 1 million parts. Mathematically, it can be represented as 1/1,000,000.
To understand the scale, let's consider an example:
If you have a liter (1000 ml) of liquid, 1 ppm would mean that there is 1 milligram (mg) of a substance dissolved in it. So, if you dilute your pure food coloring to 1 part per million using water, it means that for every 1 million parts of the diluted solution, there would be 1 part of the food coloring.
Now, let's discuss what could be your hypothesis regarding the effect of dilution on the pure food coloring:
A hypothesis is an educated guess or prediction about the outcome of an experiment or observation. In this case, you could hypothesize that diluting the pure food coloring to 1 part per million using water will result in a significantly lighter or less intense color compared to the original concentration.
Note that a hypothesis should be specific, testable, and based on prior knowledge or observations. It should also be formulated in such a way that it can be proved or disproved through experimentation or data analysis.
