"Household States of Matter - Scavenger Hunt"
| Place | Name of Matter | Classification | Characteristics |
|---|---|---|---|

Answer the following questions:
1. Can you share an item you found from the scavenger hunt and explain why you classified it as a solid, liquid, or gas?
2. Were there any items that were difficult to classify? Why do you think that was?
3. How does understanding the states of matter help us interact with objects in our home environment?
Answer (2)
To complete the table, think about different household items you see in each location and classify them by their state of matter: solid, liquid, or gas. Here’s how you could fill in the table and answer the questions:
|| Place | Name of Matter | Classification | Characteristics || |-------|----------------|----------------|----------------| | Kitchen | ice cubes | solid | Ice cubes have a definite shape and volume, and they do not flow. | | Kitchen | cooking oil | liquid | Cooking oil has no fixed shape and takes the shape of its container, flows easily. | | Bathroom | soap bar | solid | A soap bar has a definite shape, maintains its form unless acted upon. | | Bathroom | hot water vapor | gas | Hot water vapor spreads out to fill the entire space, no fixed shape or volume. | | Bathroom | shampoo | liquid | Shampoo takes the shape of its container and can pour. | | Living Room | cushion | solid | A cushion keeps its shape and does not change unless pressed. | | Living Room | air inside a balloon | gas | The air fills the balloon completely taking its shape, expands to fill the balloon. | | Living Room | candle | solid | A candle has a fixed shape and does not flow. | | Garage or Garden | gasoline | liquid | Gasoline can be poured, takes the shape of its container and flows easily. | | Garage or Garden | lawnmower | solid | A lawnmower has a definite shape and volume. | | Garage or Garden | carbon dioxide from exhaust | gas | Carbon dioxide spreads to fill the space around it with no fixed shape or volume. |
Item Example: Ice Cubes in the Kitchen - I classified ice cubes as a solid because they maintain a definite shape and do not flow like liquids or expand like gases.
Difficult to Classify: Some items can be difficult to classify, for instance, toothpaste. It’s sometimes challenging because it behaves like both a solid and a liquid - it holds its shape in the tube but flows when a force is applied. This can be described as a non-Newtonian fluid.
Understanding States of Matter: Knowing the states of matter helps us handle and store items effectively. For example, understanding that gases expand to fill their container teaches us to securely store volatile substances. Knowing liquids flow informs us to use spill-proof containers, and recognizing solids’ fixed shape helps us stack and arrange objects efficiently.
The table categorizes various household items found in different locations by their states of matter: solid, liquid, and gas. By understanding these classifications, we can interact with objects in our environment more effectively. Some items may be hard to classify due to their mixture of characteristics between solids and liquids.
