Sinking and Floating worksheet - Free Printable

Let's solve this worksheet step by step. The task is to determine whether each object will float or sink in water, and then mark "yes" or "no" in the appropriate box beside it.

We'll analyze each object based on its density and material:

---

1. Beach Ball (Rainbow-colored ball)

- Made of lightweight plastic, hollow inside.
- Filled with air, which makes it less dense than water.
- Will float → ✔ Float: yes

---

2. Scissors

- Made of metal (usually steel), which is dense.
- Metal objects typically sink in water unless they are very thin or hollow.
- Scissors are solid and heavy → Will sink → ✘ Sink: yes

---

3. Iron (Clothing iron)

- Made of metal (like steel or aluminum), heavy and dense.
- Designed to be hot and press clothes — not light.
- Definitely heavier than water → Will sink → ✘ Sink: yes

---

4. Apple

- An apple is mostly made of water and has air pockets inside.
- Most apples float in water because their density is slightly less than water.
- This is a common science fact — an apple floats!
- Will float → ✔ Float: yes

---

Final Answers:

| Objects | Float (yes/no) | Sink (yes/no) |
|---------------|----------------|---------------|
| Beach Ball | yes | no |
| Scissors | no | yes |
| Iron | no | yes |
| Apple | yes | no |

✔ Explanation Summary:
- Float: Objects that are less dense than water (e.g., beach ball, apple).
- Sink: Objects denser than water (e.g., scissors, iron).

This helps children understand basic buoyancy concepts!
