DANGERS OF INCOMPLETE COMBUSTION

Comparing combustion Complete graphing your data from the last experiment page 227 SciPad. Answer the questions page 227.

SOOT (CARBON) AND CARBON MONOXIDE Carbon particles can affect the lungs causing respiratory problems. Carbon monoxide gas is colourless, odourless and very toxic. It competes with oxygen for the haeomoglobin in the bloodstream. What is haemoglobin? https://www.youtube.com/watch?v=wKIrbq2pWvw Complete the SciPad questions page 228

WORD EQUATIONS – page 229 Remember the possibilities for combustion equations. Fuel + oxygen = carbon dioxide + water (complete combustion) Fuel + oxygen = carbon + water (incomplete combustion producing soot) Fuel + oxygen = carbon monoxide + water (incomplete combustion producing toxic gas) Fuel + oxygen = carbon monoxide + carbon + water (incomplete combustion producing soot + toxic gas) Read the questions carefully and decide if they are showing complete or incomplete combustion then decide what is produced by the reaction.

The Greenhouse Effect What is it? https://www.youtube.com/watch?v=ZzCA60WnoM k Page 230 SciPad read the information and answer the questions

Atmosphere – page 231 SciPad Page 231 cut out the atmosphere labels at the bottom of the page. As you watch the youtube clip stick the labels onto your SciPad. https://www.youtube.com/watch?v=WaikvaAw2n k

Carbon Dioxide in the Atmosphere Page 232 SciPad Using the information in the table on page 232 graph the data as two separate lines on your graph. One uses the vertical axis on the left, the other the vertical axis on the right. Answer the questions on page 234 using the graph you have drawn. We will go over questions 5 and 6 as a class.

Global Warming https://www.youtube.com/watch?v=oJAbATJCugs https://www.youtube.com/watch?v=E7-12y1GycI

Writing Paragraph Style Answers Underline the main points of the question Outline how global warming might affect the area you live in. 2. Plan the key points you need to include in your writing. 3. Link your points together to form paragraphs using because, therefore, in contrast to, etc 4. Include a conclusion/summary sentence.

Global Warming Effects Page 235 SciPad Using the paragraph answer information we have just made up, answer the question in your books. I would like to see the space in your books full.
