**Homework -> Read and make notes from Pearson section 5.6 - quick test on this homework in our lesson on Monday** (there is a soft copy of this section also on SharePoint)



The following dot points were done as notes in class and as part of your assessment task:





Lichens

Bioindicators in air pollution research

NOx -> O3 production video explanation []

Chemical formulae explaining air pollution phenomena @ I must have that formula



Play -> Smog City 2








See **Mr Kremer`s Science Site** - it is an excellent resource. He has created dot point summaries for nearly, but not all, of the syllabus key focus areas. The summaries for Topic 5 - Pollution Management, are VERY useful. Download them from Mr Kremer`s site!



See **Temperature Inversions** in this online text on the Urban Environment Use the information presented to create a visual representation to explain how thermal inversions trap smog

The pH scale

 * Rainwater is normally slightly acidic**
 * Acid rain has a pH of below 5.6** (numerous sources state this)

There is **dry deposition** (oxide particles, aerosols and gases - fall directly onto the ground) and **wet deposition** (acidic oxides dissolve in cloud droplets - rain, mist, snow, hail) of acids - from the **sources** to the **receptors**;
