Post-Class Activities

Number, Units, and Mechanics: Student Post-Class Activities

Following the pre and in-class activities that focused on the correct use of numbers, units, abbreviations and mechanics in writing, you should be feeling more confident about getting your style right with regard to these important components.

As ever, your primary goal when communicating science to any audience should be to tell an interesting story in a way that is easily understandable. These post-class activities have been designed to give you specific practice in capitalizing words correctly, working more with units, and using commas and hyphens appropriately.

Capitalization

It can be especially hard to learn when you should (and should not) capitalize certain words in your writing. The following list includes a few of the most important, common rules that you should always try to apply:

1: Capitalize the first word of a new sentence, or quote, but not if it follows a semicolon or colon. Do not capitalize the first word in the second part of an open/divided quote (e.g. Learning cellular processes is difficult; there are so many names and theories involved).
2: Capitalize people’s names, but titles only when they come before those names (e.g. Professor Michelle Richards or Michelle Richards is a professor).
3: Capitalize points of the compass only when referring to specific geographic places (e.g. Northwest Territory, and northern Canada).
4: Capitalize proper nouns and place names, but not seasons (e.g. Vancouver General Hospital is situated just off Broadway in Vancouver).
5: Capitalize the titles of publications, in print, online, and in video (e.g. New Scientist).
6: Capitalize the names of specific academic courses but do not capitalize non-specific topics or subjects (I really enjoy history).

Question 1 (5 marks)

There is one capitalization-based error in each of the five sentences below. Try to find the error in each sentence before re-writing it correctly. Copy and paste the sentences and bold the five changes you have made (1 mark for each correct change).

A) Conducting phone surveys during the Summer months, such as July and August, is not ideal as many Canadians go on vacations during this time.

B) Occasionally, solar flares occur that are large enough for the northern lights, or aurora borealis, to be seen further South than usual in locations such as Vancouver and Toronto.

C) A recent paper in nature describes how researchers modified a standard technique in order to capture better images of protein structures.

D) Most UBC science students must take 100-level biology courses, such as biology 112 and 121.

E) A current UBC Professor is a member of the Canadian Olympic Committee and will oversee Canadian athletes in Sochi as the Chief Medical Officer.

Using Plurals and Punctuation

Another difficult combination of mechanics rules to learn incorporates the mixing of rules dictating capitalization, pluralization, and the basic punctuation around numbers and units that you commonly use in scientific communication. For example:

1: You should include a space between a number and unit (20 m), but not if the unit is a degree (180°) or a percentage (55%).
2: You should not pluralize units (20 kg, not 20 kgs) unless you also write out the number (eight kilograms).
3: You should not capitalize unit names (centimetres, not Centimetres) unless you are talking about Celsius or Fahrenheit (because these two are named after scientists).

As ever, remember that consistency is everything; this is why it is acceptable to use numbers when using units, but why you should instead write them when writing out the units in full (5 m or five metres).

Question 2 (5 marks)

There are five numbers and/or mechanics-related errors in the following paragraph. Try to find the errors and re-write them correctly. Do this by copying and pasting the paragraph before bolding the changes that you have made (1 mark for each correct change).

Last summer, I took measurements of two lime trees. One was treated with fertilizer and one was not. At the end of the summer, the fertilized lime tree was 13.6 % taller than the unfertilized tree at three ft tall. Limes from the fertilized tree weighed 45 g, on average, which is almost twice as much as the unfertilized limes. Once picked, the fruit was stored at room temperature, about 21.3 ˚ Celsius. Fertilized limes held about 37 mls of juice while unfertilized limes contained only 20 milliliters.

Using Commas

Commas are used to split up sentences and make a reader pause when you want them to. As such, they put emphasis on your writing where you want it to be. If you don’t use commas often enough, this emphasis will be lost and your writing will be less easy to interpret. However, overusing commas has the same result. In all cases, read your sentences thoroughly and ask yourself whether you want your reader to pause where the commas are. If not, you might not need them.

Question 3 (5 marks)

Read the paragraph below, which comprises five sentences. Your task is to decide whether each of these sentences requires a comma or not. Copy and paste the paragraph and add in commas where you think they belong (1 mark for each sentence). Hint: Not all sentences require a comma, and no sentences require more than one. You will gain 1 mark for each sentence in which you place a comma correctly, and 1 mark for omitting a comma from a sentence that does not require one.

Some people may think that synthetic pesticides are the main pesticides found in food. Naturally occurring pesticides are also present in the foods we eat however. For example a wide variety of common fruits and vegetables produce natural pesticides to protect themselves against different fungi and insects. Natural pesticide concentrations may increase when plants are stressed or in danger. Concentrations of natural pesticides occurring in fruits and vegetables are generally low enough to be safe for human consumption yet these concentrations can be up to 10,000 times higher than those of their synthetic counterparts.

Using Hyphens

Hyphens are used to make compound words, and can be harder to master than commas. The simple rule you should follow, when deciding whether or not to hyphenate one or more words, is to read the whole sentence in which these words are present and ask yourself whether the message is the same with or without the hyphens. If it is, then you don’t need them.

For example, ‘I was deeply concerned about my lack of revision ahead of the midterm,’ would be interpreted the same as ‘I was deeply-concerned about my lack of revision ahead of the midterm,’ which means the first version is correct (you should not use a hyphen here). However, ‘I volunteered with four year olds,’ or ‘I volunteered with four year-olds,’ is not the same as ‘I volunteered with four-year-olds.’ Depending on how old the children were, you should either use the second or third versions here (the first one is always wrong, because the children are either one or four years old).

Question 4 (5 marks)

Read the paragraph below. Your task is to place five hyphens throughout the paragraph where they are needed (1 mark for each correctly placed hyphen). Hint: There are five hyphens (in total) that should be added; you might need to link two or more words together with the hyphens. If you place more than five hyphens, you will be penalized!

Recently, 10 year old Nathan Gray of Nova Scotia discovered a supernova (a massive explosion that occurs during the final evolution of a star) in the very distant galaxy called PGC 61330. Likely the youngest person to discover a supernova, Gray was examining photos taken by Halifax based astronomer David Lane, of St. Mary’s University, when he made the discovery. His discovery comes at the end of a six month long endeavour to try to beat his sister’s record as she also discovered a supernova when she was 10. Luckily for Gray, his adventurous attitude and determination allowed him to beat his sister, but only by a mere 33 days.

Question 5 (5 marks): Putting it all together

To answer the following question (scenario), write just one sentence that incorporates all the information included in Table 1 (below). Remember to follow all style-based rules and try to write the sentences in an engaging, simple way.

Table 1: Write one sentence that incorporates all the elements in the Q5 scenario. Hint: every element has been written in words in the table, but you might need to change the styles appropriately in your sentences/stories. Don’t worry too much about the content of your sentence; you can make it up as long as your sentence reads well and shows your command of Unit 3 skills.

Question (Scenario)	Organization	Focus of sentence	Measurement (size and units)	Mechanics to include
Q5	British Antarctic Survey (1 mark) Hint: this is a research centre	A reported concern that the rapid thinning of Pine Island Glacier in Antarctica is irreversible (1 mark)	Sea level could rise by up to ten millimetres over the next twenty years (1 mark)	At least one hyphen and one comma (1 mark each, 2 marks total)

Question 1 (5 marks)

There is one capitalization-based error in each of the five sentences below. Try to find the error in each sentence before re-writing it correctly. Copy and paste the sentences and bold the five changes you have made (1 mark for each correct change).

A. The Street next to Rogers Arena is called Abbott Street.

B. The current President of UBC’s Undergraduate Chemistry Society is President Michael Acceptor.

C. Another UBC society had a movie night last November but did not show March of the Penguins, which shows how the penguins’ march to sea gets easier by march each spring.

D. Chemistry and Biology would be useful subjects to know in some detail if you were a palaeontologist looking for fossils in Africa.

E. In the famous movie, Jurassic Park, Dr. Ian Malcolm hilariously pointed out the difference between this theme park and others. “If the Pirates of the Caribbean breaks down,” he said, “The pirates don’t eat the tourists.”

Using Plurals with Capitals and Units

Another difficult combination of mechanics rules to learn incorporates the mixing of rules dictating capitalization, pluralization, and the basic punctuation around numbers and units that you commonly use in scientific communication. For example:

1: You should include a space between a number and unit (20 m), but not if the unit is a degree (180) or a percentage (55%).
2: You should not pluralize units (20 kg, not 20 kgs) unless you also write out the number (eight kilograms).
3: You should not capitalize unit names (centimetres, not Centimetres) unless you are talking about Celsius or Fahrenheit (because these two are named after scientists).

As ever, remember that consistency is everything; this is why it is acceptable to use numbers when using units, but why you should instead write them when writing out the units in full (5 m or five metres).

Question 2 (5 marks)

There are five numbers and/or mechanics-related errors in the following paragraph. Try to find the errors and re-write them correctly. Do this by copying and pasting the paragraph before bolding the changes that you have made (1 mark for each correct change).

When completing our lab safety induction, my partner and I had to make various measurements of our equipment. Our lab bench stands at a height of 94cm, and it is approximately six m long. Our lamp weighs just over 3 kgs, and is so strong that the heat from it increased room temperature by 2.1 %, to 16.8˚ celsius, after just 30 min.

Using Commas Effectively

As you improve as a science communicator, you are certain to develop greater skills in using grammatical mechanics correctly in your writing. You probably already use commas very frequently, but it can still be hard to always use them appropriately. If you fail to use a comma when there should be a natural pause in a sentence, like here, your readers will be confused; however, if you overuse commas, your readers will be equally baffled as to what you are trying to tell them.

Question 3 (5 marks)

Read the paragraph below, which comprises five sentences. Your task is to decide whether each of these sentences requires a comma or not. Copy and paste the paragraph and add in commas where you think they belong (1 mark for each sentence). Hint: Not all sentences require a comma, and no sentences require more than one. You will gain 1 mark for each sentence in which you place a comma correctly, and 1 mark for omitting a comma from a sentence that does not require one.

Ideally doctors should speak slowly and calmly to patients when they first wake up following surgery. At least until good news can be delivered that is. In these instances it would be acceptable to use some humour. Connecting to patients in a personal way is a very important goal for any doctor. Despite this maintaining a professional stance is always crucial.

Using Hyphens Correctly

Remember the video that you watched about hyphenation on the ‘UBC Science Writing’ YouTube channel (see: http://www.youtube.com/watch?v=ZRV8Y13xSgI). As the video showed, you should only use hyphens between the words that are meant to act as single adjectives in a sentence, which is why it matters whether you write “I saw a man-eating rabbit” or “I saw a man eating rabbit.”

Question 4 (5 marks)

Read the paragraph below. Your task is to place five hyphens throughout the paragraph where they are needed (1 mark for each correctly placed hyphen). Hint: There are five hyphens (in total) that should be added; you could need to link two or more words together with each one.

A six week summer chemistry program designed to teach high performing youngsters to think more critically about science has been successful in developing their attitudes. Using a recently developed questionnaire, students were classified on a scale ranging from naïve to expert based on the way they answered different prompts. Before the program began, the majority of these students, who were all eight year olds, provided naïve answers; however, after completing the program, they provided expert like answers much more frequently.

Question 5 (5 marks): Putting It All Together

To answer the following question (scenario), write just one sentence that incorporates all the information included in Table 1 (below). Remember to follow all style-based rules and try to write the sentences in an engaging, simple way.

Table 1: You must write one sentence that incorporates all the elements in the Q5 scenario. Hint: every element has been written in words in the table, but you might need to change the styles appropriately in your sentences/stories. Don’t worry too much about the content of your sentence; you can make it up as long as your sentence reads well and shows your command of mechanics skills.

Question(Scenario)	Organization or company	Focus of sentence	Measurement (size and units)	Mechanics to include
Q5	The American Chemical Society (1 mark)	There is a concern that there will be a lack of helium soon in the US (1 mark)	US supplies could be reduced by fifty per cent by 2014 (1 mark)	Hyphen, comma (1 mark each, 2 marks total)

Numbers, Units and Mechanics: Student Post-Class Activities

As ever, your primary goal when communicating science to any audience should be to tell an interesting story in a way that is easily understandable. These post-class activities have been designed to give you specific practice in capitalizing words correctly, and in working more with units. Other activities deal with editing text to make it more engaging while following the rules you have learned already.

Using Capitalization Appropriately

It can be especially hard to learn when you should (and should not) capitalize certain words in your writing. The following list includes a few of the most important, common rules that you should always try to apply:

5: Capitalize the titles of publications, in print, online, and in video (e.g. New Scientist).
6: Capitalize the names of specific academic courses but do not capitalize non-specific topics or subjects.

Questions 1, 2, 3, 4, 5, 6, 7 and 8 (1 mark each, 8 marks total)

There is one capitalization-based error in each of the following questions. Try to find the error and re-write the sentence correctly. Copy and paste the sentence and bold the change you have made (1 mark for each question).

Q1: The Street next to the Nitobe Memorial Garden is called Lower Mall.
Q2: The current President of UBC’s Biological Society is President Ivy Wang.
Q3: Richard and Lily are members, along with Sophie, Lily’s Sister.
Q4: The society had a movie night in November but did not show March of the Penguins, which shows how the penguins’ march to sea gets easier by march each spring.
Q5: Despite being bordered by the icy Southern Ocean, rivers do exist in Antarctica. The most northerly is called the Rezovski creek.
Q6: Science and Geography would be useful subjects to know in some detail if you were a research scientist working in the intense cold of Antarctica.
Q7: Some believe evolution can be used as an argument against the existence of God. Atheists do not believe in God, but polytheists believe in more than one God.
Q8: Agnostics believe that it is impossible to know whether God exists, but this does not make them atheists. “The mystery of the beginning of all things is insoluble to us,” said Mr. Charles Darwin, “And I for one must be content to remain an agnostic.”

Using Plurals and Punctuation

Another difficult combination of mechanics rules to learn incorporates the mixing of rules dictating capitalization, pluralization, and the basic punctuation around numbers and units that you commonly use in scientific communication. For example:

1: You should include a space between a number and unit (20 m), but not if the unit is a degree (180°) or a percentage (55%). 2: You should not pluralize units (20 kg, not 20 kgs) unless you also write out the number (eight kilograms). 3: You should not capitalize unit names (centimetres, not Centimetres) unless you are talking about Celsius or Fahrenheit (because these two are named after scientists).

Questions 9, 10, 11 and 12 (3 marks each, 12 marks total)

There are three numbers and/or mechanics-related errors in the following four sentences (questions). Try to find the three errors and re-write the sentences correctly. Do this by copying and pasting the sentences before bolding the changes that you have made (3 marks for each question).

Q9: My girlfriend is 174cm tall but I am taller by nine cm at 183cm.
Q10: When we first bought our dog, he weighed six kilograms and was approximately three ft long. Now he weighs 25 kgs, and is approximately four ft long.
Q11: 88percent of people polled in a recent survey admitted that they did not know what a temperature of 80° F would approximate to on the celsius scale.
Q12: My goldfish is 112 mms long, which makes him 27 mms (or 19.4 %) shorter than my friend’s goldfish.

Question 13 (10 marks)

In the paragraph below there are 10 major stylistic errors. These include mistakes relating to the use of numbers, abbreviations, units, and basic punctuation and writing mechanics. Copy and paste the text and bold your re-written versions of the errors that were originally present (1 mark for each correctly re-written part).

“The Pearson published Biological Science continues to be a very popular textbook at many Universities in North America (USA and CAN). When first printed in the late 00’s, the diagram focused book did not feature as many research issues as relevant to Canadian Students as the current edition, published in 2011. Although it is not cheap to buy at approximately 160 dollars, there are over 1500 pages full of useful information. Different courses require different textbooks, but much of the material in one book will also be present in another; for example, if you were to take introductory biology: Biology 100 at UW (the University of Washington), this book would probably be fine.”

Questions 14 and 15 (5 marks each, 10 marks total)

To answer the following two questions (scenarios), try to write just one sentence that incorporates all the information included in each scenario of Table 1 (below). Remember to follow all style-based rules and try to write the sentences in an engaging, simple way.

Table 1: You must write two sentences (one for each scenario/question) to tell a story incorporating all the elements in each specific scenario. Hint: every element has been written in words in the table, but you might need to change the styles appropriately in your sentences/stories.
