Chemistry is the science that connects all other sciences and explains how everything is constructed and works. It began with the discovery of chemical processes still used today. Modern chemistry originated with the understanding of mass conservation during substance changes. The second discovery was the nature of matter and its makeup, while the third development was Mendeleev's classification of elements. Chemists help treat diseases by developing new medicines, support doctors in hospitals by analyzing patient samples, ensure food quality through testing, play a major role in plastic production, and work to reduce pollution through purification methods.

1. Chemistry

2. Summary
 What is summary?
 -a shorter version of the original
 Why do we need summary?
 -to highlight the key ideas, the main points worth
remembering
 What is the first step?
 -find key words
 What are key words?
 -meaningful repeated words often replaced by
synonyms
 Where do key words usually appear?
 -in opening and closing sentences, headings, titles

3. Paragraphs titles
 What is particular about chemistry as a
science?
 How did chemistry begin?
 How did the modern chemistry originate?

chemistry?

4. Paragraph 1
 What is particular about chemistry as
a science?
 Chemistry is the science which
connects all other sciences and
explains how everything is
constructed and works.

5. Paragraph 2
 How did chemistry begin?
 Chemistry began with discovery of
many chemical processes that are in
use today.

6. Paragraph 3
 How did the modern chemistry
originate?
 With the understanding of what
happens to substances when they are
changed, which brought scientists to
the idea of mass conservation.

7. Paragraph 4
 What was the second discovery in
chemistry?
 The second discovery was related to
the nature of matter and its make up.

8. Paragraph 5
 What was the third development in
chemistry?
 The third development was about the
classification of elements made by
Mendeleev.

9. Careers in chemistry
 How do chemists help to treat and
cure diseases?
 Through the development of new
medicines for diseases and search for
better treatments for some incurable
diseases.

10. Careers in chemistry
 How can chemists support doctors
working in hospitals?
 Through analysis of samples from
patients and study of patients
response to treatment.

11. Careers in chemistry
 What do chemists do to make sure we
have good quality food?
 Through conducting tests on food
products and a thorough control of
their quality as well as the
development of new methods of
meeting standards.

12. Careers in chemistry
 What part do chemists play in the
production of plastics?
 Chemists play a major role in the
production of plastics because it is
due to chemical processes designed
by chemists that oil is turned into
plastics.

13. Careers in chemistry
 How are chemists working to reduce
pollution?
 Pollution is reduced through the
development and implementation of
purification methods

14. Notetaking techniques
 spacing between points
 abbreviations
 underlining/capital letters
 Indenting (paragraphing)
 ordered points
 different colours
 keywords only

15. Grammar in context
 Complex subject
 Chemistry is often said to be the central science.
 Modal verbs
 Ancient man must have wondered what happened to the wood he
burnt
 Past Simple vs Past Perfect
 Although Lavoisier was the first to publish his ideas, Lomonosov had
reached the same conclusions some years earlier
 Constructions with infinitive
 Even while chemists were divided on atomism, it became necessary
for someone to make senses of the growing list of elements
 Emphatic constructions
 It was by burning things that ancient man discovered iron and glass
 Inversion
 So accurate was his classification of the elements, that he was able
to predict the properties of undiscovered ones.
