Chemistry - Metallica

Objective:
Students will investigate the properties of common metals and their reactions using simple, household materials.

Materials Needed:

Metals (can use common items):
- Aluminum foil (aluminum)
- Copper wire (copper)
- Iron nails (iron)
- Steel wool (iron)

Household liquids:
- Vinegar (acetic acid)
- Baking soda solution (sodium bicarbonate)
- Lemon juice (citric acid)
- Saltwater (dissolve salt in water)

Containers:
- Small cups or jars (plastic or glass)
- Paper towels for cleanup
Safety:
- Safety goggles (can use old glasses or craft goggles)
- Gloves (optional, for handling materials)
Other Supplies:
- Weighing scale (if available, but can estimate weight)
- Notebook for observations

Introduction to Metals:
Briefly discuss different types of metals, their properties, and uses. Emphasize concepts like reactivity and corrosion.
Metal Selection:
- Assign each group a specific metal (aluminum, copper, iron) and provide the corresponding metal item.
Conducting Reactions:
- Step 1: Weigh the metal samples if a scale is available, or estimate their weight.
- Step 2: Place the metal sample in a cup and cover it with one of the household liquids (vinegar, lemon juice, or saltwater).
- Step 3: Observe any reactions (bubbling, color change) and note the time taken for changes to occur.
Data Collection:
- Record observations on how each metal reacts with different solutions. Note any changes in color, texture, or mass (if measured).
Analysis and Discussion:
- Groups will share their findings with the class, discussing the reactivity of their metals and why certain metals corrode faster than others.

Conclusion:

Summarize the importance of understanding metal properties in real-world applications (e.g., construction, transportation).
