Let me carefully analyze the problem.

The task is about calculating density using the formula:
Density = mass / volume

We are given a table with four liquids (yellow, green, red, orange) and two solids (blue cube, pink star), each with their mass (g) and volume (cm³). We need to compute the density for each in g/cm³.

Also, there’s a matching part:
“1. Which liquid is the most dense?
2. Which liquid is the least dense?
3. Which object will settle to the bottom? (Pick one.)”

Then instructions:
- Use colored pencils to sketch the liquid layers in the container on the right.
- Add the two solid objects at the appropriate locations.

So first, I’ll compute densities:

1. Yellow liquid: mass = 2.8 g, volume = 2 cm³ → density = 2.8 / 2 = 1.4 g/cm³
2. Green liquid: mass = 6 g, volume = 3 cm³ → 6 / 3 = 2.0 g/cm³
3. Red liquid: mass = 1.5 g, volume = 3 cm³ → 1.5 / 3 = 0.5 g/cm³
4. Orange liquid: mass = 1.3 g, volume = 1 cm³ → 1.3 / 1 = 1.3 g/cm³

Solids:
- Blue cube: mass = 2.4 g, volume = 2 cm³ → 2.4 / 2 = 1.2 g/cm³
- Pink star: mass = 2.4 g, volume = 1 cm³ → 2.4 / 1 = 2.4 g/cm³

Now rank all densities:
- Red liquid: 0.5
- Orange liquid: 1.3
- Blue cube: 1.2 → wait! 1.2 < 1.3, so blue cube is less dense than orange liquid
Let me reorder correctly:

Densities:
- Red liquid: 0.5
- Blue cube: 1.2
- Orange liquid: 1.3
- Yellow liquid: 1.4
- Green liquid: 2.0
- Pink star: 2.4

So:
1. Most dense liquid = green liquid (2.0)
2. Least dense liquid = red liquid (0.5)
3. Object that settles to the bottom = the densest object overall = pink star (2.4 g/cm³), since it’s denser than all liquids.

For layering: In a container, liquids stack from least dense (top) to most dense (bottom). Solids sink or float depending on whether they’re denser or less dense than the liquid they’re in.

So order from top to bottom:
1. Red liquid (0.5) — top
2. Blue cube (1.2) — will float *on* orange liquid? Wait—no: solids are placed *in* the column; they sink until they reach a liquid denser than themselves.

Actually, standard rule: An object will sink through any liquid less dense than itself, and float on any liquid more dense than itself.

So:
- Pink star (2.4): denser than all liquids (max liquid density = 2.0), so sinks to bottom.
- Blue cube (1.2): less dense than yellow (1.4) and green (2.0), but denser than red (0.5) and orange (1.3)? Wait: 1.2 < 1.3, so blue cube is *less dense* than orange liquid (1.3), so it floats *on* orange? No — if object density < liquid density, it floats *on top* of that liquid.

Let’s compare blue cube (1.2) to each liquid:
- Red (0.5): 1.2 > 0.5 → sinks through red
- Orange (1.3): 1.2 < 1.3 → floats on orange
So blue cube ends up *between* red and orange layers — i.e., sits on top of orange layer.

But the container drawing shows 4 colored layers (from top: yellow, green, orange, red?) Wait—the image shows a 4-layer container with colors: top = yellow, then green, then orange, then red at bottom — but that seems inconsistent with densities unless we reinterpret.

Wait — maybe I misread the container. Let me zoom into the container image to see current coloring.

Since’t actually view the image directly, but based on standard problems like this, the container is empty and we are to fill it with layers *in correct order*.

Given densities:
- Red: 0.5 → top
- Orange: 1.3
- Yellow: 1.4
- Green: 2.0 → bottom

So liquid layers (top to bottom):
1. Red
2. Orange
3. Yellow
4. Green

Now solids:
- Blue cube: 1.2 → denser than red (0.5), less dense than orange (1.3) → so it sinks through red, stops at orange layer → sits *on top of orange*, i.e., between red and orange.
- Pink star: 2.4 → denser than all → sinks to very bottom, below green.

But the problem says: “Add the two solid objects at the appropriate locations” — likely in the container drawing, which has 4 liquid bands and space for solids.

However, the question only asks for:
1. Which liquid is most dense? → green
2. Which liquid is least dense? → red
3. Which object will settle to the bottom? → pink star

So final answers are:
1. green liquid
2. red liquid
3. pink star

But the instruction says: “Final Answer: [Provide only the final correct answer.]”

Since there are three parts, probably list them clearly.

Let me re-read the user instruction:
"→ Always follow the structure below.
→ If an option is false, completely omit that section."

All options (ExplainAnswer, TeachTopic, GeneratePractice) are false, so only "Final Answer" section appears.

So I must give only the final answer — likely as a concise response to the three questions.

Given typical format for such worksheets, the expected final answer is:
- Most dense liquid: green
- Least dense liquid: red
- Object that settles to bottom: pink star

I’ll write it cleanly.
