Collect 5 different items around your house. You will investigate the physical and chemical changes that these items could go through. List your 5 items, describe their characteristics (color, size, shape, etc). Describe the physical and chemical changes each item could go through. Fill in the chart below

Answer 1

Answer: One idea for one item you could write on SLIME!

Explanation: for an idea for one item, you could do slime for characteristics you could write about the chemical change and of course, since slime sits out, you could write about the physical change for chemical change, you could write about how the chemicals make it smell.

Answer 2

Step-by-step explanation:

1. Apple: Characteristics - Red color, round shape, medium size.

- Physical Change: Cutting the apple into slices.

- Chemical Change: Apple slices turning brown when exposed to air.

2. Candle: Characteristics - White color, cylindrical shape, small size.

- Physical Change: Melting the candle wax when exposed to heat.

- Chemical Change: Burning the candle, where the wax reacts with oxygen to produce heat, light, and carbon dioxide.

3. Iron nail: Characteristics - Silver color, cylindrical shape, small size.

- Physical Change: Bending the nail with force.

- Chemical Change: Rusting of the nail when exposed to moisture and oxygen in the air.

4. Ice cube: Characteristics - Transparent color, cuboidal shape, small size.

- Physical Change: Melting the ice cube when exposed to heat.

- Chemical Change: Dissolving the ice cube in water, where the solid water molecules break down into liquid water molecules.

5. Paper: Characteristics - White color, flat shape, medium size.

- Physical Change: Folding the paper into different shapes.

- Chemical Change: Burning the paper, where the cellulose fibers in the paper react with oxygen to produce ash, heat, and carbon dioxide.

It's important to consider the specific characteristics and properties of each item when determining the possible changes they can undergo.
