Technicians’ lists of equipment Downloaded from www.catalystscience.co.uk Catalyst 2, Unit G: Rocks and weathering Lesson G1: Rock breaking Starter activities Problem solving For each group: one piece of each of several rocks (eg limestone, sandstone, chalk, mudstone, granite, basalt, gneiss, marble, slate) hand lens. If possible provide several different types of rocks such as limestone and sandstone. These are likely to have different colours and/or grain sizes but otherwise be similar Main activities G1a Rocks and porosity For each group: rock samples hand lens 400 cm3 beaker top-pan balance stopwatch paper towels G1b Physical weathering For the teacher: 2 glass bottles with screw lids 2 rubber bands Bunsen burner beaker of ice cubes in water 2 clear plastic bags glass rod forceps Lesson G2: Disappearing rocks Starter activities Capture interest (1) 2 ×400cm3 beakers, 2 Petri dishes, marble chippings, hydrochloric acid of 2.0mol dm−3 concentration, filter funnel, filter paper This list is in Microsoft Word, so it can be customised to fit each school’s requirements. 1 Technicians’ lists of equipment Downloaded from www.catalystscience.co.uk Catalyst 2, Unit G: Rocks and weathering Main activities G2a Chemical weathering For each group: watchglasses dilute sulphuric acid dropper samples of limestone, sandstone, granite and chalk G2b Where weathering happens world map(s) showing maximum and minimum temperatures world map(s) showing rainfall Lesson G3: Transporting rocks Main activities G3a How do sediments move? For each group: shallow tray clamps tube from cold water tap large plastic trough sand brick G3b Erosion For each group: clay cubes (11/2 cm cubes fired in a kiln) sieve access to a digital balance newspaper plastic bottle or jar Lesson G3 Investigate: Does particle size affect deposition? Starter activities Setting the context 1000cm3 measuring cylinder four or five different diameter marbles (three of each size) stopwatch Introduce the apparatus 100cm3 measuring cylinder, This list is in Microsoft Word, so it can be customised to fit each school’s requirements. 2 Technicians’ lists of equipment Downloaded from www.catalystscience.co.uk Catalyst 2, Unit G: Rocks and weathering non-permanent felt-tip pen, access to balance, stopwatch, sand of several grain sizes Main activities G3d Does particle size affect deposition? For the teacher: 1000cm3 measuring cylinder several marbles of each of four or five diameters stopwatch For each group: 100cm3 measuring cylinder non-permanent felt-tip pen stopwatch access to a balance sand of several grain sizes Lesson G4: Layers of sediment Starter activities Problem solving a variety of different fossils or photos of fossils Main activities G4a Swirling sediments For each group: 1000 cm3 beaker 100 cm3 beaker mixture of sand, gravel and stones G4b Evaporating sea water For each group: sea water 50cm3 measuring cylinder evaporating basin Bunsen burner tripod gauze ceramic mat ‘Sea water’ can be made by dissolving 35g of sodium chloride per dm3. This list is in Microsoft Word, so it can be customised to fit each school’s requirements. 3
