I would first start with a general lesson introducing carboniferous limestone landscapes, then do a case study on the landscape of the Yorkshire Dales. Starter Tell your partner three facts about limestone e.g. formation, what it's made from, examples, distribution in UK. Review some answers and establish that students know that limestone is formed mainly of calcium carbonate, which comes from the remains of coral and sea shells and was formed on the seabed. We'll look at one particular type of limestone called carboniferous limestone. This creates distinctive landscapes because it is susceptible to chemical weathering from the weak acids in rainwater, it is laid down in layers called bedding planes and has vertical joints and these weaknesses are vulnerable to weathering and finally because it is a permeable pervious rock which means that water can flow through these joints and bedding planes. Main activities Surface features Students are given photos of limestone features and descriptions, such as this activity on the BBC Education Scotland site 'Upland Limestone: Surface features'. With a partner they match them up. Students then write a brief description of the landform, possibly on a worksheet with photos or diagrams of the features. Ask students what they think happens to the water when it flows down a sinkhole or under a dry valley, what did a resurgent stream look like before it reached the surface. Underground features Students are given a diagram of a limestone cave system and a description of its different components. They then watch this BBC Bitesize video 'Underground features of upland limestone scenery' and check if they were correct. Then they write a brief description for each feature. To check their understanding we could adapt the 'Spot the Feature' activity on the BBC Education Scotland site into a game where photos are shown on a power point slide and students spot the features they've just learnt about. Plenary Pictionary - you have one minute to draw one of the landforms we learnt about in this lesson, your partner has to name it. Case study: Yorkshire Dales![]() Characteristics
- Limestone pavements e.g. above Malham Cove - Dry valleys e.g. The Dry Valley of Watlowes - Gorges - Caves e.g. Ingleborough Caves Human activity

[Accessed on 11/08/15] Available from: http://www.bbc.co.uk/schools/gcsebitesize/geography/rock_landscapes/rock_types_rev2.shtml Starter Show a short clip of Harry Potter and the Deathly Hallows. Ask if they can name the limestone features shown and if they know where it was filmed. (On the limestone pavement at the top of Malham Cove). Main activities Students are shown a selection of photos of different limestone features in the Yorkshire Dales, they have to name the feature and describe how they were formed. Students are then given an OS map of the area and have to identify these formations and give correct grid references. Brainstorm the human uses of the area, using a collage of photos if necessary. Discuss as a class what impact these activities have on the physical landscape. Show students this clip of the BBC's 'The Trip' with Steve Coogan visiting Malham Cove. After watching, ask students to imagine they are the Malham Cove know-it-all, and write an information leaflet for visitors to the Yorkshire Dales, recommending places to visit and explaining the characteristics and formation of the landscape, as well as suggesting recreational activities in the are. This could be done for homework so that students could make a proper leaflet with maps, photos and diagrams. Plenary Give students a card from a pack of cards. I draw a card out of another pack and the student with the corresponding card has to tell me one thing they've learned about the Yorkshire Dales today.
