| Lesson 1: Igneous rocks:
rocks from fire. Students will be introduced to the
concept of rocks from molten material. An investigation of the
size of crystals in a variety of igneous rocks enables students
to make deductions regarding cooling rates. |

| Lesson 2: Geological time.
The concept of geological time will be explored. Students
will learn something of the historical figures and scientific
discoveries, which enable geologists to date the earth. |

| Lesson 3: Weathering, erosion
and transportation. Using igneous rocks to illustrate
the way in which rock breaks down over time students will be
introduced to the concepts of physical and chemical weathering.
The difference between weathering and erosion will be explained.
The concepts of transportation and deposition will be explored. |

| Lesson 4: Formation of clastic
sedimentary rocks. A structured introduction to the
formation of clastic sedimentary rocks builds on knowledge gained
in the previous lessons. A practical session enables students
to explore the properties of the rocks. Students will use their
observations to help them make deductions about the weathering
profiles of each rock type examined |

| Lesson 5: Formation of bio-clastic
sedimentary rocks. An introducion to the formation
of carbonate rocks linked to a practical session that explores
the properties of rocks. Students are made aware of the links
between the weathering profiles of clastic and bioclastic rocks |

| Lesson 6: Metamorphic rocks.
Major earth processes. The rock cycle. An explanation
of the formation of metamorphic rocks. An introduction to anticlines
and synclines linking their formation to major earth structures.
A brief explanation of plate tectonics in order to complete
the rock cycle. |

| Lesson 7: Rocks in the landscape.
Application of the knowledge gained in earlier lessons. Students
use a range of images, geological maps and internet sources
to help them relate bedrock geology to landscape formation.
Students will be introduced to the role rocks play in soil formation
and, therefore the ecology of an area. |

|
| Lesson 8: Fieldwork. Fieldwork
provides opportunities for enquiry based learning, planning,
working in groups, analysis and evaluation. A trip to the local
cemetery will enable students to investigate weathering processes
in action on a range of rock types. A group project makes use
of an urban trail to encourage students to look at their own
surroundings whilst considering the properties of rocks used
as building materials. Teachers should also consider checking
the local English Nature Area Team website pages for support
with fieldwork. |
