Worksheet: Identifying Physical and Chemical Properties
Instructions:
Use this worksheet to record the physical and chemical properties of the materials you are examining (water, wood, plastic, metal, glass). Fill in the table below with your observations. For each property, write down your findings or predictions.
Material: ___________________________
(Write the material being tested in the space above)
| Property | Description | Observation/Prediction |
|---|---|---|
| 1. Color | The color or appearance of the material | ______________________________ |
| 2. Texture | How the surface feels (smooth, rough, soft, hard, etc.) | ______________________________ |
| 3. Density | Mass per unit volume. Will the material float or sink in water? | ______________________________ |
| 4. Melting Point | The temperature at which the material melts (if applicable) | ______________________________ |
| 5. Boiling Point | The temperature at which the material boils (if applicable) | ______________________________ |
| 6. Flammability | Can the material catch fire? | ______________________________ |
| 7. Solubility | Does the material dissolve in water or other solvents? | ______________________________ |
| 8. Flexibility | Can the material bend without breaking? | ______________________________ |
| 9. Electrical Conductivity | Does the material conduct electricity? | ______________________________ |
| 10. Reactivity with Air | Does the material react with oxygen or other gases in the air (e.g., rusting)? | ______________________________ |
| 11. Reactivity with Water | Does the material react with water (e.g., dissolving, bubbling, rusting)? | ______________________________ |
| 12. Transparency | Is the material transparent, translucent, or opaque? | ______________________________ |
| 13. Hardness | How resistant is the material to scratches or indentations? | ______________________________ |
| 14. Magnetic Properties | Is the material magnetic? | ______________________________ |
| 15. Thermal Conductivity | How well does the material conduct heat? | ______________________________ |
Additional Notes:
- Predictions: For properties like boiling point, melting point, or reactivity, try to predict how the material might behave before testing it.
- Bonus Observations: If you have time, conduct tests (e.g., heating the material, applying pressure) and note any changes. Describe them in the "Observation" column.
Reflection (after completing the tests):
- Which material had the most interesting or unexpected properties? Why? ----
- How did the material’s physical and chemical properties influence its potential uses? ----
- Which property would be the most important for choosing a material for a specific application (e.g., cooking, construction)? ----
