Fruit Float or Sink Investigation Activity (teacher made) - Free Printable

I'll help you solve this fruit float or sink experiment! Let me work through each fruit step by step.

Step-by-step analysis:

1. Avocado: Avocados have a large pit and dense flesh. They typically SINK in water because they're denser than water.

2. Banana: Bananas are less dense than water due to their air pockets and structure. They FLOAT.

3. Apple: Apples contain air pockets in their flesh, making them less dense than water. They FLOAT.

4. Watermelon: Watermelons are mostly water but have air spaces inside. They FLOAT (especially when whole).

5. Orange: Oranges with peel can float due to air pockets in the rind, but peeled oranges sink. Since it shows a whole orange, it would likely FLOAT.

6. Lemon: Lemons typically FLOAT because of their thick rind with air pockets.

7. Lime: Limes are similar to lemons but slightly denser. They usually FLOAT.

8. Grape: Grapes are small and dense. They SINK in water.

Let me verify these answers:
- Dense fruits (avocado, grape) → Sink
- Fruits with air pockets or less dense structure (banana, apple, watermelon, citrus fruits) → Float
