Question
Point Value: 8 points
Suggested Time: Two to three 45-minute class periods
Task Overview:
Using their background knowledge from the passage, students will research the importance of mineral hardness in a real-life scenario. For example, a student could consider why some minerals are better to use in kitchen counter tops than others. Students will compile their research into a short presentation. Finally, students will incorporate a multimedia or visual display to add clarity or interest to their presentation.
Student Directions:
In “Mineral Hardness Test Experiment: Using the Mohs Scale to Determine the Hardness of Minerals,” you learned how scientists identify unknown minerals by measuring their hardness. You will be researching the importance of mineral hardness in a real-life scenario. For example, you may choose to research why some minerals are better to use in kitchen counter tops than others. You will compile your research into a short presentation that includes a multimedia or visual display.
Part 1:
Research how minerals are used in everyday life. For example, quartz is used analog watches, gold is used in dental work, and diamonds are used in some drill bits. Make a list of reasons why minerals of different degrees of hardness are ideal for some purposes. For each bullet give examples of situations in which a particular mineral is used. Then, choose one mineral and research reasons why that mineral is used for a particular purpose—how does the mineral’s hardness contribute to its usability?
Part 2:
Compile the research about your chosen mineral into an interesting presentation. Using the information from the Mohs Hardness Scale in the passage as well as your research, create a multimedia or visual display to enhance your presentation. For example, you could incorporate a video simulation showing how some materials are more durable than others.
Part 3:
Share your presentation with the class. Be sure to consider your audience when choosing the language you use in your speech. Also remember the importance of speaking slowly, and clearly so that your message is heard.
Scoring:
Your work will be scored based on:
The accuracy and detail of your research
The accuracy of your presentation
The appropriateness and effectiveness of your incorporated visual or multimedia display
The clarity of your speech

## Student Project Guidelines: Researching Mineral Hardness and Its Real-Life Applications
### Overview
In this project, you will explore how the hardness of minerals impacts their use in everyday life. You will investigate specific minerals, their applications, and prepare an informative presentation that incorporates a visual or multimedia display.
### Part 1: Research on Mineral Hardness
1. **Understand the Concept**:
- Recall that minerals have varying degrees of hardness, measured by the Mohs Hardness Scale (from talc at 1 to diamond at 10).
2. **Identify Everyday Uses of Minerals**:
- Make a list of minerals and their applications based on hardness:
- **Soft minerals (1-3)**:
- **Talc (1)**: Used in talcum powder, as a lubricant.
- **Gypsum (2)**: Used in drywall and plaster.
- **Moderate hardness minerals (4-6)**:
- **Fluorite (4)**: Used in toothpaste and as a flux in steelmaking.
- **Apatite (5)**: Used in fertilizers and as a gemstone.
- **Hard minerals (7-9)**:
- **Quartz (7)**: Used in watches and countertops.
- **Corundum (9)**: Used in sandpaper and abrasives.
- **Diamond (10)**: Used in cutting tools and jewelry.
3. **Choose One Mineral**:
- Select one mineral from your list and investigate its specific use. Consider the following:
- What is the mineral's hardness level?
- Why is its hardness beneficial for its particular application?
- Are there any limitations or drawbacks to using this mineral?
4. **Research Example (for Quartz)**:
- **Use**: Kitchen Countertops
- **Hardness**: 7 on Mohs Scale
- **Reasons**:
- Scratch-resistant
- Durable and long-lasting
- Non-porous and easy to clean
- **Conclusion**: Quartz's hardness contributes to its ability to withstand wear and tear in a kitchen environment, marking it as an ideal choice for countertops.
### Part 2: Presentation Preparation
1. **Organize Your Research**:
- Create an outline for your presentation, including key points about your chosen mineral, its hardness, and its applications.
2. **Visual or Multimedia Display**:
- Decide on a format to enhance your presentation, such as:
- Presentation software (e.g., PowerPoint)
- Infographic
- Video simulation demonstrating the hardness of various materials
- Physical samples of minerals (if available)
3. **Create Your Presentation**:
- Keep slides or visual aids clear, organized, and visually appealing.
- Use images, charts, or graphs to support your points.
- Write speaker notes to guide you during your presentation.
### Part 3: Presentation Delivery
1. **Practice Your Speech**:
- Rehearse your presentation multiple times.
- Ensure you're speaking slowly and clearly.
- Pay attention to how you engage with your audience; make eye contact and use appropriate gestures.
2. **Deliver Your Presentation**:
- Present your findings to the class.
- Encourage questions and be prepared to discuss your research further.
### Scoring Criteria
You will be assessed on the following:
- **Research Accuracy and Detail**: Depth of information and understanding of mineral hardness.
- **Presentation Accuracy**: Correctness of facts and clarity of information.
- **Visual/Multimedia Effectiveness**: Quality and relevance of visual material used in enhancing your presentation.
- **Clarity of Speech**: Ability to communicate clearly and effectively during your presentation.
### Additional Tips:
- Start your research early to allow ample time for preparation.
- Use credible sources for your information, such as scientific articles or educational websites.
- Have fun and express your interest in the subject matter to engage your audience!
Good luck with your project!
