Natural disasters: Earthquake - The Richter Scale
This activity encourages communication between students and helps develop comprehension.
Level: Intermediate and above
Language Aims: To practice text organization and sequencing skills. To develop confidence in working with unfamiliar texts. To become familiar with some words related to earthquakes.
Time: 20 minutes
Preparation: Make enough sets of Text 1 below so there is one set per group of five students. The sections need to be cut up so that you can give each student one section. If you do not have enough students to have five students working together, have groups of three or four and give one or two of the students more than one section.
Make enough copies of Text 2 so that each student in a group of five will have a set of the questions (each person in a group of five gets one set of 7 questions). Make enough copies of Text 3 so that each group has one copy of it
1. Divide students into groups of five and give each student in a group one of the sections of Text 1. Their aim as a group is to put the five sections of the text in order. Students work alone and read through their section, discuss the ideas of the section with their group and then put the five sections in order. They should not use dictionaries for this activity or show other members of the group their part of the article. Quickly review answers as a class.
2. Give each student in a group a set of Text 2 questions. The student who has Section 1 (the first part) of the article must not get the Student 1 questions. They can go to anyone else in the group. This rule applies for all the sets of questions. The student who has the Student 1 questions will be asking the student with Section 1 of the article for the answers. Students work to find the answers to their questions and help other group members answer their questions.
3. Students complete the Text 3 tasks.

Write my paper for me
To be successful in life, you need a university education. To what extent do you agree with this statement?
The fact is, a university education is what you make of it. Half the students will graduate with a solid direction or goal, but the other half will still be as unclear about their next career move as they were when they started. Granted, a university education is essential if you want to have a career in a profession such as law, engineering, teaching, or medicine but it does not guarantee you a job; many graduates are unemployed or have to get work in other fields. Also, you do not necessarily need a university degree to become a wealthy movie star, sports star or businessperson; look at Tiger Woods, Steve Jobs or Bill Gates for example.
A university education can help you achieve some types of success, but it does not guarantee success in the work force or indeed, in other areas of your life.
