Introduction
Billy and Paul were on a journey to the shop. On their way the talked and laughed about everything that they saw. While walking along, they met upon a beautiful glistening rock. “Wow!” said Billy as he picked it up. “I wonder where this rock came from?” asked Paul. “I am very curious to find out what type of rock this is and also what really are rocks,” said Paul. Therefore they both decided to take it to school to ask their teacher what kind of rock it was.
The following day they took to rock to Mr. Senior, for him to tell them what type of rock it was. Mr. Senior looked at the rock and smiled at the boys and said, “Boys, later during our Science lesson you learn about this rock, as well as others.” The boys ran away happily and went to devotion.
Task
Students will:
1. Clink on link to say what are rocks and minerals and the main types of rocks?
2. Identify and name the three different types of rocks as shown in picture
3. Give examples of each type of rock.
4. Place different types of rocks under their correct headings.

-
Billy and Paul , as well as the other students of the grade four class want to know what rocks are. Click on the link below to find out what rocks and minerals are and the main types of rocks
-
All of the students are excited about identifying the different types of rocks from prior knowledge of using the flipped classroom. They will click on the link below to look at pictures of rocks and touch and say their names
-
Work in groups to identify names and give examples of and categorise the different types of rocks under the correct headings:
granite, limestone, gneiss, sandstone, pumice, obsidian, shale, slate, marble, conglomerate, basalt, chert, schist.

Conclusion
Good job learning about what rocks are, the main types of rocks and how they are formed. You will now be able to recall what the main types of rocks are and identify them in your daily walk. The use of the internet played a great role in assisting you with information before hand, therefore the internet is a great tool for gaining information, as long as it is used for the right purposes.

What are Rocks?
The earth’s crust is made of rock, and rock is made of natural substances called minerals. There are three main types of rocks. These are sedimentary, igneous and metamorphic rocks.
The Rock Cycle
The rocks that form earth’s crust are continually destroyed and remade in an endless process called the rock cycle. A rock is formed by melting, cooling and solidifying, by changing through heat and pressure, by weathering and erosion and by compression and cementation.
What are Igneous Rocks?
Igneous rocks form when magma (molten rock) rises from deep underground and cools and solidifies at or near the earth’s surface. Igneous rocks that form under the ground may later reach the surface because of geological upheaval. It may also be exposed as the rocks above are worn away. Igneous rocks include granite and basalt
What are Sedimentary rocks made of?
Sedimentary rocks are made of fine rock particles that have been worn away and then carried by rivers, glaciers or the wind and are collected in lakes and oceans. The tiny fragments are then compressed or squashed and cemented together to form sedimentary rocks. These rocks include sandstone, limestone and chalk.
How are Metamorphic rocks created?
Metamorphic rocks are formed existing rocks are changed underground by great heat or pressure or both. When volcanoes erupt, rocks are heated and squeezed. The minerals in the rocks are then changed, forming metamorphic rocks. Examples of these are marble, slate and schist.
