Let’s think about which things will float in water.
Floating means the object stays on top of the water instead of sinking to the bottom. Things that are light for their size — like wood, plastic, or air-filled objects — usually float. Heavy or dense things (like metal) often sink.
Let’s go one by one:
1.
Apple – Apples have air inside them and are less dense than water →
✔ Floats
2.
Beach ball – It’s full of air and very light →
✔ Floats
3.
Leaf – Leaves are thin and light, they sit on top of water →
✔ Floats
4.
Glass bottle – If it’s empty and sealed, it can float because of the air inside →
✔ Floats *(Note: if filled with water, it sinks — but we assume it’s empty unless told otherwise)*
5.
Banana – Bananas are mostly water and fiber, but they’re buoyant enough to float →
✔ Floats
6.
Key – Made of metal, heavy for its size →
✘ Sinks
7.
Nail – Also metal, small but dense →
✘ Sinks
8.
Seaweed / Kelp – Often floats naturally in oceans →
✔ Floats
9.
Bell – Usually made of metal →
✘ Sinks
Wait — let’s double-check the glass bottle. In real life, an empty glass bottle *can* float if it’s sealed and has air inside. But sometimes kids might think “glass = sinks”. However, scientifically, if it’s hollow and sealed, it floats. Since this is a basic worksheet, and no info says it’s broken or filled, we’ll say it floats.
Also, seaweed/kelp — yes, it floats naturally.
So final list of things that float:
- Apple
- Beach ball
- Leaf
- Glass bottle
- Banana
- Seaweed
Things that sink:
- Key
- Nail
- Bell
Final Answer:
Circle these: apple, beach ball, leaf, glass bottle, banana, seaweed
Parent Tip: Review the logic above to help your child master the concept of sink and float worksheet for kindergarten.
