Presenting Scientific Data

Many people have pets. One survey of pet owners showed the following breakdown of the type of pets owned: 35% dogs; 35% cats; 10% birds; 5% hamsters, gerbils, mice, rats; 5% reptiles; and 10% other. 1.Copy the incomplete circle graph below on your paper. Complete the graph using the survey data. Estimate the angle of each section of your completed circle graph. Give your graph a title and label what each section of the graph represents. 2.Explain how viewing the graph conveys information to the reader more quickly than reading the list of data.

a. Variable y is plotted vs. variable x. b. Showing how a variable responds to changes in another c. Scaled bars used to represent d. Comparing a similar various measurements set of data e. A divided circle, with each “slice” f. Showing how a part relates to representing a proportional fraction the whole

 Using a table is a simple way to present data visually.  The table relates two variables – a manipulated variable (location) and a responding variable (average annual precipitation).

Plotting the mass of water against the volume of water yields a straight line. What is the volume of 3g of water? 3cm 3 What is the mass of 9 cm 3 of water? 9g Useful for showing changes that occur in related variables. ‘rise’ = change in the y-variable ‘run’ = change in the x- variable

 The mass of the water is directly proportional to the volume, meaning that the ratio of two variables is constant.  (if one goes up, the other goes up)  An inverse proportion is a relationship in which the product of 2 variables is a constant =  (if one goes up, the other goes down) Each point on the graph above represents the same volume of water: 1 gallon.

Useful for comparing several measurements, amounts of changes.

(1) Celsius Scale – widely used in chemistry and the everyday scale of temperature in most countries.  0  C is the freezing point of water  100  C is the boiling point of water at sea level. (1) Celsius Scale – widely used in chemistry and the everyday scale of temperature in most countries.  0  C is the freezing point of water  100  C is the boiling point of water at sea level.

(2) Kelvin Scale – is the SI scale and is based solely on the properties of gases.  Used in most calculations.  0 (zero) is the lowest attainable temperature on this scale and is referred to as ABSOULUTE ZERO. It is equivalent to –  C. On the Kelvin scale water freezes at 273 K and boils at 373 K. (2) Kelvin Scale – is the SI scale and is based solely on the properties of gases.  Used in most calculations.  0 (zero) is the lowest attainable temperature on this scale and is referred to as ABSOULUTE ZERO. It is equivalent to –  C. On the Kelvin scale water freezes at 273 K and boils at 373 K.

(3) Fahrenheit Scale – the common temperature scale in the United States which is not generally used in scientific studies.  Water freezes at 32  F and boils at 212  F. (3) Fahrenheit Scale – the common temperature scale in the United States which is not generally used in scientific studies.  Water freezes at 32  F and boils at 212  F.

You will need to know how to convert among all three temperature scales. These are the formulas that you will need to MEMORIZE! K =  C  C = 5/9 (  F - 32)  F = 9/5 (  C) + 32 *Remember to always do what is in parenthesis first! You will need to know how to convert among all three temperature scales.

Liquid nitrogen, which is often used as a coolant for low- temperature experiments, has a boiling point of 77K. What is the temperature on the Fahrenheit scale?  First convert 77K to Celsius:  T c =T k = = -196 o C  Next convert Celsius to Fahrenheit   F = 9/5 (  C ) + 32   F = 9/5 (-196oC) +32 =  F
