BIG picture What skills will you be developing this lesson? HSW- by planning and carrying out an investigation/ Interpreting data/ evaluating an experiment Literacy- by writing explanations using correctly spelt keywords and good grammar. Team work- during a practical investigation Participation- during a practical activity Reflection- through self and peer assessment of each outcome Key Question: What is the difference between an element and a compound? Quick Discussion: What do you already know? How is this lesson relevant to every day life? Chemicals and reactions used to work machines for example, for fireworks Where does this lesson fit in to the rest of the topic? Lesson 4

Keywords: Create sentences using the keywords to show that you know what they mean. Put your hand up if there is any key word from the list that you don’t understand. Fossil Fuels Hydrocarbons Oxidised Combustion Limestone Greenhouse gases Greenhouse effect Global warming Emissions Sulphur dioxide Carbon dioxide Acid rain nitrous oxides

New Information for Task 1

Teacher Demonstration Using the hydrogen balloon attached to a metre ruler. Light it. What happens? New Information for Task 1

What are fossil fuels and the three main ones? GasOilCoal New Information for Task 1

Burning fuel, like coal, petrol and natural gas, provides > 90% of the energy needed for transport, factories and in the home. New Information for Task 1

Fossil fuels are also hydrocarbons: –This means they are made up of hydrogen and carbon only. New Information for Task 1

What happens when a lighted splint is put into a tube of hydrogen? Hydrogen releases energy when it reacts with oxygen Where can hydrogen be used as a fuel? Why is hydrogen a good fuel? Learning Activities for Task 1a

When fuels burnt it reacts with what gas and gives of what? Reactions which take in energy is called what type of reaction? Most fuel molecules are made of which two elements and after complete burning what two compounds are they formed into? What gas can be detected by bubbling it into limewater and what colour does the limewater turn into? Learning Activities for Outcome 1

How Coal was Formed. Stick the pictures in the right order and then stick the right description underneath. Step 1Step 2 Step 3 Step 4Step 5 Stick picture here Stick writing here New Information for Learning Outcome 2 a

Cut these pictures and descriptions out and stick them in the right places on the worksheet Forests in swamps millions of years ago. Trees and animals die and get buried in mud. The dead trees and animals get squashed and heated in layers underground. The dead trees and animals have turned into coal. The coal is dug out of the ground (mined).

New Information for Learning Outcome 2b

Carbon dioxide is the main greenhouse gas involved the warming of the Earth by the greenhouse effect. Human activity is producing more carbon dioxide and other greenhouse gases. An increase in the amount of greenhouse gases could increase the amount of heat trapped in the atmosphere. Some scientists think that this increased greenhouse effect is making the Earth warmer and leading to global warming. What human activities might contribute to global warming? New Information for Learning Outcome 2a

Task 2: Using the keywords on the right to help you, research up and produce a leaflet on the effects of burning fossil fuels.research Include the following: a)how fossil fuels are made b)the uses of fossil fuels c)the disadvantages of fossil fuels d)how fossil fuels can be conserved Keywords for Task 3: greenhouse gases greenhouse effect global warming emissions sulphur dioxide carbon dioxide acid rain nitrous oxides Learning Activities for Outcome 2

Normal rainwater has a pH of about 5.6, which means it is naturally slightly acidic. This natural acidity is due to carbon dioxide which dissolves in rainwater and forms a weak acid. Rainwater with a lower pH than normal is called acid rain. The burning of fossil fuels in power stations and cars forms pollutants such as sulphur dioxide and nitrogen oxides. These gases dissolve in rainwater to make sulphuric and nitric acids, which are strong acids and so form acid rain. Why is acid rain a serious environmental problem? New Information for Learning Outcome 2

Acid rain can be particularly bad in that it can have an effect on rivers, trees and buildings made out of limestone: New Information for Outcome 3

Task 3: On your leaflet by carrying out research explain what effect rainwater has on limestone and why? Keywords for Task 3: limestone acid corrode react neutralisation sulphur dioxide nitrous oxides Learning Activities for Outcome 3
