Prepare |
|
|
|
- 2 Class Periods (90 minutes)
|
|
|
|
|
- Review all activities and discussion questions in the Teacher Edition (TE) pages 18, 19, and 20.
- Gather the materials needed to complete the Teach with Inquiry and Differentiate activities on page 18 and the Extension activity on page 19.
- If you are doing the extension, download the Crystal Growing Lab Data Sheet from the JASON Mission Center and make a copy for each student.
- Download the Salt Crystal Dissolved by Water and Cave Formations transparencies.
- Test all links on your computers.
- Set up a projector for watching the video.

- Review the five characteristics of minerals by selecting student volunteers to name and explain each one.
- Ask students to suggest some ways minerals might form.
- Show students the Characteristics of Minerals and Mineral Formation video.
- Have students revisit their suggestions about mineral formation in light of the new information.

This brief video covers the characteristics that all minerals must have and explains their formation from molten rock, from metamorphism, and from solution.

Teach |
|
|
|
|
- Have students read or listen to pages 18, 19, and 20 in the Student Edition (SE). As they read, have then highlight the topic sentence of each paragraph.
- Discuss the reading, using the discussion questions corresponding to these pages in the TE.
- As you discuss the section on Minerals from Solution, use the transparency provided to show the chemical reaction of salt dissolving in water. You can also use the Cave Formations transparency to show stalactites and stalagmites.
- Have students make stalactites and stalagmites, following the instructions in the Teach with Inquiry activity on page 18. For best results, use a lot of baking soda, so the solution is super-saturated. When draping the string, don’t let the center of the string hang below the top of the solution or the solution is likely to drip too fast to form stalactites. If stalactites are slow to form, move the beakers closer together so the center of the string hangs lower. Be sure to have students check frequently so they can watch the stalactites and stalagmites form.
- Differentiate: Use the Differentiate activity on page 18 with students who need additional exposure to solutions.
- Differentiate: Have students research one of the topics introduced in this section of the SE, as described in the Differentiate activity on page 19.

This article describes how minerals can form from the cooling of molten rock, from solutions, and from metamorphism. The factors that influence how minerals form are also discussed. |

|
 |
Reflect And Assess |
|
|
|
|
- Have students answer the Check for Understanding questions on page 20 of the student edition.
- Use the research assignment described in the Assess section on page 19 to assess students’ learning.
- Have students find photographs or samples as examples of each of the different ways minerals can form.
|
|
|
|
 |
Follow-up |
|
|
|
|
- Have students grow their own crystals, using the crystal growing lab described in the Try This! and Extend sections on page 19 of the SE and TE. Instruction and data sheets are available in the JMC. Be sure to have students monitor and record the rate of growth for each crystal so they can be compared.
- As students bring in rock samples throughout the Mission, have them look for mineral crystals within the rocks. Are they always visible? Why or why not?
- Use students’ examples of each the different ways minerals form to create a wall chart similar to the Formation of Minerals chart on page 20 of the SE. Have students supply accompanying text describing each process.

In this lab, students will use different solutions to grow crystals with different sizes and shapes. |
