Let’s go step by step to check the answers on this worksheet.

The task is called “Skittles Density Rainbow.” The idea is that you use different numbers of Skittles for each color, and then arrange them in a rainbow — with the color that has the *most* Skittles at the bottom (because it’s “denser” or heavier), and the one with the *least* at the top.

Here’s what was written:

- red: 2
- orange: 4
- yellow: 6
- green: 8
- purple: 10

Then the question asks:
“What color do you think should be on the bottom?”
Answer given: purple

Now let’s think about density here. In this experiment, more Skittles = more sugar dissolved = denser solution = sinks to the bottom.

So we need to find which color has the *highest number* of Skittles — because that will be the densest and go on the bottom.

Looking at the numbers:

- red: 2 → smallest → top
- orange: 4
- yellow: 6
- green: 8
- purple: 10 → largest → bottom

Yes! Purple has the most Skittles (10), so it should be on the bottom.

That matches the answer written on the paper.

Also, if we were building the rainbow from bottom to top, it would be:

Bottom: purple (10)
then green (8)
then yellow (6)
then orange (4)
top: red (2)

Perfect order — increasing density downward.

So everything checks out.

Final Answer:
purple
