The River Avon – From Source to Mouth. The River Avon, from Source to Mouth Dick Bateman SBL 2004
Lesson Plan ideas 00 min Learning Objectives for SBL 90 and Teachers at UWE conference. On Whiteboard - Title How to sketch a river valley from a slide plus Date plus Learning Objectives 1. To learn how to sketch a river valley from a slide (using key words for valleys). 2. To develop the ability to think and work collaboratively putting photos in sequence 3. To visualise, describe and explain future developments within the valley. 05 min Starter (Review of prior learning) Using the Map of the River Avon Basin Students find the source, note the course and find the mouth of the River Avon. 9 students are asked to name the towns from source to mouth. 10 min Review/register completedActivities explained 1. 10 Students view slides. Students read captions aloud in register order. 2.15 mins Teacher shows how to draw a sketch of Sherston slide . Students draw their versions and create their own (share-writing) captions for slide 6 3. 20 mins Students resume viewing slides and reading out the captions. 4. 30 mins Students work in pairs to put photo laminates into likely sequence from source to mouth 5.40 Stretcher Pairs discuss then choose the slide where you think there is most likely to be development [houses, roads, bridges, picnic area, woods] IN YOUR LIFETIME. 6.In exercise books draw slide as it is. Underneath write 3 bullet points to explain why it is likely to develop 50 Plenary Two pairs review each others’ choices and think up objections. Extended Work Students draw a second sketch in their books to show how landscape of their chosen slide is likely to develop, with 1 bullet point objection and 1 bullet answer.
It is narrow enough to step over and shallow enough just to get your socks wet if you step in it. It is a narrow stream called a rill, flowing through grass and bushes. 0.1 km Height 170 metres Width 0.5 metre Depth 200 mm
After 1 km the stream broadens out as it goes under a road bridge. The stream has been dammed back into a pond, possibly so that cattle can drink here. There is a farm downstream from where the river starts. This field is used as pasture, probably for cattle, because it is likely to be wet. 1 km from source Height 160 metres Width 2 metres Depth 200 mm
The river starts bending around corners. Each bend is called a meander The Avon now has a flat flood plain on one side of its valley This village is called Sherston. 5 km from source, at Sherston Height 150 metres Width 3 metres Depth 800 mm Steep valley sideThe valley side is too steep to farm, so it is left for woodland Gentle valley side, used for cattle pasture like the flood plain.
Downstream from Sherston, this building looks new. It was an old mill, using water power to grind corn. It has been renovated into expensive flats The river is now wide enough to need a footbridge 6 km from source Height 150 metres Width 4 metres Depth 900 mm Where two rivers meet is called a confluence.
Upstream from Malmesbury, the river shows rapids and pools. The rapids are where the river flows over rock outcrops. In flood time the river breaks off bits of rock, rounds them off, then dumps them as pebbles in its bed 9 km from source Height 110 metres Width 5 metres Deepest Depth 1.2m The pool is where the river is dammed back behind the rock outcrop.
At Malmesbury this large mill has also been converted into flats. Willow trees are managed by their branches being “pollarded” (cut back so new small shoots grow) 10 km Height 100 metres Width 10 metres Deepest Depth 3 metres
Notice how lines of trees follow the river. The river is now meandering with wide bends. Near Sutton Benger, people like fishing in the river Avon for the peace and quiet. This black dot was a mink. It is a very fierce little animal 20 km from source Height 60 metres Width 10 metres Deepest Depth 3 metres
In Bath. Some businesses take tourists for cruises on the River Avon. Some people live on their boats This is Pulteney weir in Bath. It was designed in a beautiful curve to be an ornamental feature in the centre of Bath. 50km from source Height 15 metres asl Width 20 metres Deepest Depth 4 metres
People like to sail in peaceful places, like the Avon at Saltford. Sometimes people litter in the river. This is polystyrene. 55 km from source Height asl 10 metres Width 25 metres Deepest Depth 4 metres
The River Avon from near Willsbridge Hill. Notice the wide flood plain. The hedge marks the edge of the river terrace which is above the flood plain. Hanham woods are left on the valley sides where it is too steep for farming. 58 Km from source Height 7 metres asl Width 30 metres Deepest Depth 6 metres The wide flood plain downstream from Keynsham and the Cadbury’s chocolate factory.

This is Hotwells. Some homes here used to be warehouses for trade along the river. 65 km Height 1 metre asl Width 50 metres Deepest Depth 10 metres In Clifton Wood, slave traders built large mansions from their profits. Narrow boats are now used to live on and as river taxis.
The River Avon flows through its gorge underneath the 50 metres high Clifton Suspension Bridge. Its very muddy where it drops all the mud from up stream. 68 km from source Height 1 metre asl Width 40 metres bank to bank Deepest Depth 10 metres [high tide]
Huge cranes lift containers from the freighter ships Each container can hold 100 tons of goods This dock is near the mouth of the River Avon. 75 km from source Height asl 0 metres Width 50 metres Deepest Depth 30 metres
Ideas for further Innovation Flash for place names e.g. Sherston and geographical features, e.g. meander Audacity for relevant music, e.g. river sounds, birdsong Animation where relevant possibly from timelapse photography, e.g. boat being loaded with containers Link to other activities eg websites, worksheets. Please add other ideas.
