CONTENT OF THE LESSON

MEANING OF ROCK

A rock is a solid made up of a bunch of different minerals.

 

 

TYPES OF ROCKS

There are three major types of Rocks – Metamorphic, Igneous, and Sedimentary rocks.

 

MEANING/DEFINITION OF IGNEOUS ROCKS

Igneous rocks are formed by volcanoes. When a volcano erupts, it spews out hot molten rock called magma or lava.

Examples of igneous rocks include basalt and granite.

 

MEANING/DEFINITION OF METAMORPHIC ROCKS

Metamorphic rocks are formed by great heat and pressure. They are generally found inside the Earth’s crust where there is enough heat and pressure to form the rocks.

Other examples of metamorphic rocks include marble, anthracite, soapstone, and schist.

 

MEANING/DEFINITION OF SEDIMENTARY ROCKS

Sedimentary rocks are formed by years and years of sediment compacting together and becoming hard.

 

Some examples of sedimentary rocks are shale, limestone, and sandstone.

 

PROCESSES OF ROCK FORMATION

The processes of rock formation is how a rock can change from igneous to sedimentary to metamorphic over time.

1. Melted rock or magma is sent to the earth’s surface by a volcano. It cools and forms an igneous rock.

2. Next the weather, or a river, and other events will slowly break up this rock into small pieces of sediment.

3. As sediment builds up and hardens over years, a sedimentary rock is formed.

4. Slowly this sediment rock will get covered with other rocks and end up deep in the Earth’s crust.

5. When the pressure and heat get high enough, the sedimentary rock will metamorphose into a metamorphic rock and the cycle will start over again.

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the students some questions; then, the teacher –

2. Lead student to define rock and differentiate between types of rocks.

 

 

Student’s Activities – Define rock and state types of rocks.

3. Discuss the processes of rock formation.

Student’s Activities – Participate actively in the classroom discussion.

4. Summarizes the lesson on the board.

Student’s Activities – Copy as the teacher writes.

 

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

 

LESSON EVALUATION 

Ask students to:

1. Define Rock.

 

 

2. Mention different types of rocks.

3. Describe the processes of rock formation.
