Introduction

Lesson Plan - Explained in detail Blue - Class Management Strategies Pink - Assessment Techniques Green - Questioning Red - Areas where Differentiation is possible Pupils line up outside the classroom Silence while I tell the pupils that their starter activity is on the board that they are to come in silently and begin. They are to put their hand up when they are finished. Written on board The questions we shall answer in today's lesson are What is weathering? What is erosion? What are the three different types of weathering? What type of weathering is acid rain? What does a rock most affected by acid rain contain? Which rock is least affected by acid rain? Starter activity to read in silence pages 98-99 (Book Eureka 2G) Brief Question and Answer Session Which of the questions written on the board can we now answer after reading pages 98 & 99? Teacher Explanation of Weathering and Erosion Stress not strictly caused by the weather as the name suggests! We cause weathering, as do plants and trees. State strongly that weathering and erosion are different and the difference between them. ...read more.

Acetate Rain water is naturally slightly acidic. Carbon dioxide from the air dissolves into the rain water turning it slightly naturally acidic. Carbon dioxide + water = carbonic acid Fossil fuels contain sulphur, when they are burned they produce sulphur dioxide. When sulphur is burnt in air this happens! Sulphur + oxygen = sulphur dioxide Sulphur dioxide is acidic! Sulphur dioxide dissolves into rain water to produce an acid called sulphuric acid this very acidic! Rocks containing calcium carbonate will be weathered most quickly by acid rain because the carbonate reacts with the acid in the rain Fast finishers to read about consequences of acid rain on page 45. Class Practical Gain class attention Count to three, eyes and ears on me! Praise those as they begin to pay attention with each number counted down - one - well done girls thank you, Two - good back row, Three! Tell this background story for the experiment: It is the year 3000 & rain water has become extremely acidic due to all the fossil fuels being burnt! Houses are being weathered away by the second; this has major implications for the economy of Britain "ask what economy is". ...read more.

Conclusion

Some of the words children will be tested on placed on OHT a few minutes to revise while I check the homework's - those who have not completed the homework will be asked to stay behind after this lesson and complete. (BREAK-TIME) White board Questions What type of weathering is acid rain? Rain water is naturally acidic, what dissolves into rain water to produce this slight acidity? What dissolves into rain water to cause acid rain? Which rock would be best to build houses out of in order to withstand the affects of acid rain? Which rock would you not want to build houses out of with consideration to acid rain? What do the rocks which react most readily with acid rain contain? (slightly harder question) What is this a definition of - Wearing away of rock by a physical or chemical process - Wearing away of rock while it is being transported Dismissal of Class Stand behind benches ask Vicky, Lee, Jamie and Danny to check the sinks - which row will be the first to go? Dismiss rows in the order in which they became silent first. ...read more.

  1. SCIENTIFIC PRACTICAL TECHNIQUES

    Get a wires and another one compare the results. To have a straighter wire as possible, placing it yourself to get better results. More time for the experiment and to repeat it 2 times. TITLE: SAMPLE OF THE GROWING CULTURE EVERY 15 MINTUES FOR AN HOUR.

  2. An Investigation of the weathering of limestone.

    This means there is not much of a chance of a reactive acid particle colliding with a limestone reactive particle. When all the liquid is acid only reacting acid particles can collide with the limestone particles so there are more successful collisions occurring.

  1. The Erosion of Marble

    2 mol/l > Marble chips CaCO3 Safety Requirements > Wear Safety glasses. > Don't crowd around sinks and weighing scales etc. > Don't run in the laboratory. > Do not taste chemicals. > Follow teacher's instructions. > Put unnecessary books and bags away so you do not trip over them.

  2. A Investigation into the Rate of Chemical Weathering of Marble

    I have chosen to measure the reaction rate using the first method because I am familiar with the use of the gas syringe and there is not enough electronic balances or dataloggers for the entire class to use. I also feel that a gas syringe will obtain a reliable result if the experiment is performed accurately.

  1. To find out what effects the weathering of the limestone building.

    The reason why it takes long to react with the large chunks is because it is big and has a big surface area which mean longer time for the acids to react with the chunks, with the small chunks it will be fats because there is a small surface area

  2. Acids, water and oxygen can all weather rocks. They break down the rocks by ...

    Particles may be atoms, ions or molecules. There is a minimum amount of energy which colliding particles need in order to react with each other. If the colliding particles have less than this minimum energy, then they just bounce off each other and no reaction occurs.
