Earth Sciences DVD

This programme introduces the processes involved in marine erosion and transportation. It includes sections on the action of the sea, erosional and transportational processes and the removal of beach material. It includes shots of processes in action on British coasts.

Drainage Basin Landforms DVD - 16 minutes Shipped in 8 days Cat.# AVP-35D $ 90.00 ADD TO CART

This programme gives a general model for differences in drainage basin morphology and river type from source to mouth. It deals with the common landforms associated with river channels and their immediate surrounding drainage basins, in both the upper and lower courses.

Ice Formation and Erosion DVD - 16 minutes Shipped in 8 days Cat.# AVP-36D $ 90.00 ADD TO CART

This programme introduces the processes involved in glaciation. It includes sections on ice formation, the physical character of ice, internal processes in the ice, corrie formation and glacial erosion. Original film of modern alpine glaciers enables pupils to see the processes in action.

River Processes DVD - 19 minutes Shipped in 8 days Cat.# AVP-37D $ 90.00 ADD TO CART

This programme introduces the hydrological cycle as a system. It then concentrates on the role of water movement through the system by focusing on hydrological processes in rivers. The programme includes original film of rivers and shots taken from a flume tank to demonstrate transportational processes.

Glacial Depositions and Landforms DVD - 15 minutes Shipped in 8 days Cat.# AVP-38D $ 90.00 ADD TO CART

This programme introduces the processes of glacial deposition, and erosional and depositional landforms. It follows on from the Ice Formation and Erosion programme by studying landforms resulting from the processes discussed. The programme includes original film of classic landforms in North Wales.

Six programmes designed to introduce processes and landforms associated with rivers, coasts and glaciers. The programmes may be used to introduce, summarise or revise topics in the classroom or to introduce fieldwork. The subject is brought alive by combining clear, concise explanations with quality visual images. All the material is original including classic examples from British coasts and rivers, alpine glaciers and British glacial landforms. The programmes are available separately, or on a single video cassette as the GCSE Physical Geography Series. Each individual programme is approximately 15 minutes long. 

This programme describes and explains the different layers within the earth. It covers the classification of extrusive and intrusive igneous rocks and how crystal size can indicate mode of formation. The programme illustrates the erosion and transportation of igneous rocks leading to the formation of sedimentary rocks, thus introducing the rock cycle. It also looks at how the shape and size of particles in sedimentary rocks can tell us how they were formed. 

Describing a Soil in the Field DVD - 11 minutes Shipped in 8 days Cat.# AVP-41D $ 90.00 ADD TO CART

This programme shows how to investigate soils by digging soil pits and by undertaking a range of techniques to investigate properties such as acidity, texture, structure and organic contents. It also covers methods of recording and interpreting the results.

What are Rocks and Minerals? DVD - 15 minutes Shipped in 8 days Cat.# AVP-42D $ 90.00 ADD TO CART

This programme covers the definition of a mineral and a rock, how minerals are combined to form rocks, why minerals have consistent physical properties and how minerals can be identified by these properties using a range of practical techniques. 

This programme consists of a comprehensive description of the development of a soil. It shows individual stages from bare bed-rock through to a fully mature soil with shots of soils developed on a different parent material.

This programme covers physical, chemical and biological weathering processes. It introduces erosion and transportation processes involved in the removal of weathered material and how soil develops from material remaining in situ.

This series of programmes covers much of the basic information needed for the study of Earth Science as part of the National Curriculum for Science(UK) at key stage 3. The programmes contain field shots, experiments and microscopy combined with concise computer graphic explanations. In addition to key stage 3, this video provides a good grounding for teachers of science at key stages 1 and 2 as well as providing a starting point for students of key stage 4 and A-level Geology and Geography courses. The programmes are designed to act as a springboard for further teacher-assisted or self study and suggestions for follow-up work are given throughout the programmes and as accompanying notes. The programmes are available separately, or on a single video cassette as the Earth Science Series. Each individual programme is approximately 15 minutes long.
