Sink or Float - Free Printable

To solve the problem of determining whether each object will float or sink, we need to consider the principle of buoyancy. An object will float if its density is less than the density of the fluid (usually water) it is placed in, and it will sink if its density is greater than the fluid's density.

Objects and Their Behavior:

1. Coin: Coins are typically made of metals like copper, zinc, or steel, which have densities much higher than water. Therefore, a coin will sink.
2. Pencil: A pencil is made primarily of wood, which has a density less than water. However, the graphite core and metal ferrule increase its overall density, making it likely to sink.
3. Cotton Ball: Cotton balls are very light and have a lot of air trapped within them, making their average density much lower than water. Therefore, a cotton ball will float.
4. Crayon: Crayons are made of wax, which has a density lower than water. Thus, a crayon will float.
5. Rubber Band: Rubber bands are made of rubber, which has a density slightly higher than water. Depending on the exact material and shape, a rubber band may sink.
6. Wooden Stick: Wood generally has a density less than water, so a wooden stick will float.

Final Answer:

- Coin: Sink
- Pencil: Sink
- Cotton Ball: Float
- Crayon: Float
- Rubber Band: Sink
- Wooden Stick: Float
