Sink and Float interactive worksheet - Free Printable

This worksheet is designed to help students understand the concept of float and sink based on the density of objects in water. The goal is to determine which objects will float and which will sink when placed in water.

---

🔍 Understanding Float and Sink:

- Objects that float are less dense than water.
- Objects that sink are denser than water.

We’ll analyze each object:

---

✔ Objects That Will Float:

1. Leaf – Light and has air pockets; less dense than water → Floats
2. Straw – Made of light plastic, hollow inside → Floats
3. Paper Tube – Lightweight and hollow, made of paper → Floats

---

✘ Objects That Will Sink:

1. Coin – Made of metal (e.g., copper or steel), very dense → Sinks
2. Key – Usually made of metal, heavy → Sinks
3. Rock – Dense mineral material → Sinks

🧪 Final Answer:

Place the items into the correct sections of the cup:

#### Float (Top Part):
- Leaf
- Straw
- Paper Tube

#### Sink (Bottom Part):
- Coin
- Key
- Rock

💡 Educational Tip:

This activity teaches children about density, buoyancy, and material properties in a fun, hands-on way. Encourage them to test predictions with real objects if possible!
