Videos on Volcanoes
USGS's video on Mount Saint Helen, which they did not allow to embed... http://youtu.be/xP2dreOI8gI
This is definitely worth watching.
And for our class activity, we are going to answer (A) and (B) in groups
Crossing the lava video clip
The "pyroclastic flow"
(A) Explain the extent these video clips are representative of the destructive nature of acidic lava type volcanoes.
Traffic jams... a town in big trouble!
(B) Explain how volcanic hazard management has failed in this movie clip and explain how you will go about setting in place a volcanic hazard management program for a town like the one portrayed in the movie.

Learning how to use excel to analyse data better
Dear Students,
For this class exercise, we are looking into how we can use simple graphs and charts to represent data and understand relationships between different data better.
We usually use a simple co-relation efficient to talk about relationship between data.
It is a simple qualitative approach that gives people an idea of the strength of the relationship between 2 different sets of data.
The degree of the relationship (positive or negative) can be quantified by calculating the R ( correlation coefficient).
Excel provides a very quick way of calculating the "line of best fit" to allow us to see the R value very fast.
A "R value" that is close to 1 means there is a strong positive relationship between the sets of data. As X increase, Y also increase.
A "R value" that is close to -1 means there is a strong negative relationship between the sets of data. As X increase, Y decreases.
Pay attention in class as Mrs Lim demonstrates the use of excel for item 1 and 3 in TASK B.
TASK A: THINK TIME:
What happens when you get a value that is close to 0? Discuss!
TASK B: EXCEL TIME (Work in pairs or trios, according to sharing of computers in class)
Download the data file from Espace IH2013 module workbin.
Open the file in Excel.
As a class, we will discuss the best way to represent data to aid the following investigations:
Preparation for first lesson in Week 8:

As a class, we will discuss the best way to represent data to aid the following investigations:
- Co-relation of population size and energy consumption per capita
- Co-relation of GDP per capita and energy consumption per capita
- Comparison of types of countries and their energy consumption per capita
- Comparsion of GDP per capita and energy consumption per capita according to types of countries
Preparation for first lesson in Week 8:
- Discuss the data representations and the implications of what you observe.
- What do the analyse suggest about the distribution of resources?
- How do the implications affect the way these countries tackle global issues on the environment?

Class Activity for Yr 4 students in GE4101
Dear Year 4 students,
Please prepare individual answers to the following questions as a follow up to the presentations on "Help Indonesia" module project. This will be covered after the magma lecture.
Q1. With the aid of well annotated figures,
(a) Explain how composite volcanic cones are formed, (6m)
(b) how different types of lava give rise to different shaped volcanoes (9m)
(c) how lakes and volcanic plugs maybe formed from previously existing volcanic cones (6m)
*NEW*
Suggested answer for 1(c). Link: https://docs.google.com/file/d/0B0NH1U79c6yJa3NIdHdkb25ZWm8/edit?usp=sharing
Q2. Refer to the video embedded below.
(a) What information do you think has been covered in this video? Has it been done adequately?
(b) What other information would you think should have been included to help online viewers understand earthquakes better?
(c) To what extent do you think this is a good video on earthquakes?
(Come to class prepared with your own critique, using 2(a-c) as a basis for preparation.)
