Science
... Rocks and Soils ...



1
Learning Intention:
To learn about the rock cycle
Instruction and differentiated activities:
*Using a simple diagram, discuss lava and volcanoes
*That lava forms rocks (igneous)
*That rocks erode and wash into water to form sedimentary rock
*Presssure, time and heat convert this to metamorphic rock
*Differentiate work - LA to use worksheet
*See a picture of our results
*Finish with Rock Cycle Song
*Detailed Lesson Plan(Word 2000)
Resources:
*Rock cycle worksheet (LA)
*Rock cycle answer sheet
*Rock Cycle Song
ICT Opportunities:
*Great volcanic clips on the Internet
2
Learning Intention:
To learn about the rock cycle
To understand how one type of rock can be transformed to another
Instruction and differentiated activities:
A SUPERB LESSON! *Recap on the stages of the rock cycle
*Use either different coloured grated chocolate, OR crayon sharpenings:
-grate - to show formation of sedimentary (and some pressure)
-Pressure (in foil and sit on - maybe use a bit of warmth - to show formation of metamorphic
-melt and pour to show formation of igneous
*Detailed Lesson Plan(Word 2000)
Resources:
*Coloured chocolate or crayons (plenty!)
*grater or sharpeners
*foil
*microwave or warm water (heat source)
ICT Opportunities:
*
3
Learning Intention:
To identify uses for rocks
To understand that some rocks are better suited to some functions than others
Instruction and differentiated activities:
*Ask children to remind you of the rock types and characteristics
*Now get children to suggest which rock type might be used more often for: carving easily, high wear areas, strong buildings etc
*Children to investigate rock samples and group into possible uses
*During plenary, identify names and uses of some common rocks
*Detailed Lesson Plan(Word 2000)
Resources:
*Rock samples
*Pictures of rocks as they are used
ICT Opportunities:
*Online pictures from BBC website (use online, or print)
http://www.bbc.co.uk/education/rocks/index.shtml
4
Learning Intention:
To group rocks by hardness - using Moh's Harness Tests
Instruction and differentiated activities:
*Recap on three types of rocks and their characteristics
*Introduce Moh's hardness indicators -as a way of grouping rocks by hardness (spend time on this - children find it difficult)
*Children perform Moh's hardness tests on a range of rock samples - ask children to rank samples in order of relative hardness
*In the plenary, use sentence frames and encourage use of scientific words and full sentences to explain findings
*Detailed Lesson Plan(Word 2000)
Resources:
*Range of rock samples
*Coins
*Blunt knives *background information - Moh
*keyword list
ICT Opportunities:
*Moh's Hardness Test
5
Learning Intention:
To understand where and how fossils form
To have the skill to manipulate materials to create a fossil effect
Instruction and differentiated activities:
*Children to remind you of the three kinds of rock
*Discuss (with reasons) why fossils remain only in sedimentary rock
*Make imprints (foot-like) - or fossil-type to make moulds for pouring plaster of paris into
*During plenary, discuss how real dinosaur footprints might be found, and how fossils form
*Detailed Lesson Plan(Word 2000)
Resources:
*Fossil samples
*Sand
*Plaster of paris
*Mixing equipment
*Keyword list
ICT Opportunities:
Online fossil images
6
Learning Intention:
To carry out an experiment to compare water retentin properties of different soils
Instruction and differentiated activities:
*Discuss what an experiment is (including fair test)
*Read a 'water problem' leeter to the class requesting their help to identify a soil that offers good drainage,br> *Discuss and conduct a drainage test
*Detailed Lesson Plan(Word 2000)
Resources:
*Cylinders
*Filter paper
*Soils (clay, compost, sandy)
*Measuring apparatus for water and soils
ICT Opportunities:

*


Further ideas:
*Biscuit chocolate chip excavations
