Salt Shaker Press: Lesson Plan: Production of Glass for 8th Grade Students at Marlinton Middle School (with video)

Lesson Plan: Production of Glass for 8th Grade Students at Marlinton Middle School

Subject: Science

Grade Level: 8

Topic: Production of Glass

Learning Objectives:

Students will be able to define glass.
Students will be able to identify the main ingredients in glass.
Students will be able to describe the process of glassmaking.
Students will be able to explain the different types of glass and their properties.

Materials:

Procedure:

Begin by asking students what they know about glass. Write their ideas on the board.
Define glass as "a hard, brittle, transparent material that is typically made by fusing silica with other oxides."
Explain that glass is a very versatile material that is used in a wide variety of products, such as windows, bottles, and mirrors.

To help students understand the process of glassmaking, you can show them a video or diagram of the steps involved.
You can also have students conduct a hands-on activity to make their own glass beads.

Once students have a basic understanding of glassmaking, lead a class discussion on the following topics:
- The different types of glass and their properties
- The uses of glass in everyday life
- The environmental impact of glassmaking

To assess students' understanding of the production of glass, you can give them a short quiz or test.
Here is a sample test question:
- What are the main ingredients in glass?
- A. Silica and other oxides
- B. Sand, soda ash, and limestone
- C. Salt, sugar, and water
- D. None of the above

Graphics and Pictures:

The following graphics and pictures can be used to help students understand the production of glass:

Diagram of the glassmaking process: This diagram shows the steps involved in making glass, from melting the ingredients to shaping and cooling the glass.
Pictures of different types of glass: These pictures can help students learn about the different types of glass and their properties. For example, you could show students pictures of float glass, tempered glass, and laminated glass.

Differentiation:

For students who need additional support, you can provide them with more graphic organizers or visual aids.
For students who are ready for a challenge, you can have them research a specific topic related to glassmaking, such as the history of glassmaking or the environmental impact of glassmaking.

Extension:

Have students design a new type of glass with specific properties.
Have students research a specific product that is made of glass and write a report on how it is made.
Have students visit a glass factory or art studio and learn more about the glassmaking process firsthand.

10-Question Test

Answers

Glass is a hard, brittle, transparent material that is typically made by fusing silica with other oxides.
The main ingredients in glass are silica, soda ash, and limestone.
The process of glassmaking begins by melting the ingredients together in a furnace. Once the ingredients have melted, the glass is shaped and cooled.
The different types of glass include float glass, tempered glass, and laminated glass.
Float glass is a smooth, flat type of glass that is commonly used for windows and mirrors.
Tempered glass is a type of glass that has been strengthened to make it more resistant to breakage.
Laminated glass is a type of glass that is made up of two or more layers of glass that are bonded together with a plastic film. This makes the glass more resistant to breakage and shattering.
Glass is used in a wide variety of products in everyday life, such as windows, bottles, mirrors, eyeglasses, and cookware.
The environmental impact of glassmaking includes the use of energy and resources, as well as the production of air and water pollution.
This is an open-ended question that allows students to use their creativity and imagination
