"Into Minerals" PPT

Description

Hunan Education Edition Sixth Grade First Volume Science, Entering Minerals PPT

Part One: Teaching Introduction

1. Teaching introduction

1. Show pictures of several common minerals or minerals and ask students to tell us what these minerals or minerals can provide us.

2. Students answer.

3. Question: What did you think of after hearing this?

4. Transition: Around us, such as glass, knives, pencil cases, pencils, pens, ballpoint pens, clothes, wires, plastics, tools, cars and boats... they are all related to mineral resources, and minerals are closely related to people's daily lives. How much do you know about minerals?

Entering the mineral PPT, part 2: understanding minerals

2. Activities: Learn about minerals

1. Present: samples of minerals and their extracts.

2. Discussion: How to observe and understand mineral specimens?

For example: prepare to study the properties of minerals, what tools are needed, what methods to use, and how to record observations. Results etc.

3. Tips:

Method Tip: In studying minerals, the most commonly used method is to use streaks to observe the color of minerals. There is a certain difference between the actual color of the mineral and the color of the streak, and the color of the streak is the true color of the mineral. To see the true color, the method is to use minerals to engrave on unglazed porcelain pieces. The color of the traces left behind is the more accurate mineral color.

Safety Tip: When comparing mineral hardness, pay attention to safety and prevent yourself from being injured by tools or minerals.

Recording requirements: The color, shape, grain, hardness, luster, streaks, magnetism or other findings of the mineral can be recorded.

3. Activity: Speculate the formation of coal

1. Reading materials

2. Analyze and infer, watch the video - the formation of coal.

Present the facts and guide students to analyze and infer one by one. The distribution of coal underground is layer by layer. What can it mean? Coal seams contain a large number of plant fossils, and some coals even have complete tree trunk shapes. What can it help us infer? What does it mean that these plants grew between 200 million and 300 million years ago? Can the formation of coal be inferred? Ask students to try to summarize the formation process of coal.

3. Organize students to watch the video - The Formation of Coal, or provide textual information introducing the formation process of coal, so that students can verify their inferences based on the information they see.

Entering the mineral PPT, the third part: the formation of coal

formation of coal

Coal is formed through long-term geological processes after layers of ancient plant remains were buried underground.

According to research, almost all plant remains can be converted into coal as long as they meet the conditions for coal formation. However, coal formed from the remains of lower plants has a small distribution range and thin thickness, and is rarely used by people. Those coals that are widely distributed, large-scale and widely used are formed from the remains of higher plants (mainly the remains of ancient ferns, conifers and some angiosperms).
