In this case, units are extremely important as they are the magnitude of a quantity. The

units give an ideal amount of length, weight, time, etc in order to be familiar with that

specific measurement. In this case, the child would benefit if units were used after the

clerk said the store was “twelve away from here” and the lollipop was worth “three”.

With the given information, the child and his father don’t know if the lollipop was 3

dollars, cents, shillings, or euros or if the store is 12 minutes, feet, meters, miles, or

even seconds away. Knowing this information is essential for the two who are trying to

purchase the lollipop and trying to find a grocery store. If the clerk was more specific

about the units, this would also give them the information in order to figure out how

much they are going to spend on the candy and how far and how much time it would

take to get to the next store.

Units are extremely important in this example. If the boy held up three pennies he

would expect to purchase the lollipop, while it might actually cost three dollars or maybe

three quarters, or nickels or whichever. Also when the clerk told the mane that the

closest grocery store is 12 it could be 12 miles, or 12 minute, even 12 exits on the

highway. It it important to use units to measure so you are able to get exactly what you

are trying to say across. If the clerk specified the units he was speaking about then

everyone would be clear what he expected.

Units would definitely help alleviate confusion within this scenario. The extra information

needed within this example is the unit of money and the unit of the distance needed to

effectively get the information across to the different individuals. The child needs to

know exactly how much money the candy is worth (three dollars? three quarters?). And

the father needs to know the distance to the grocery store. By just answering with a

number and not supplying the appropriate unit can lead to a huge over or

underestimation of what is being communicated. The father could think the grocery

store is twelve blocks away, where it is really twelve miles away.

This scenario shows just how important units are when trying to communicate

information. I’m sure that we are going to be learning all about the units presented within

chemistry such as the International System of Units and the Metric System and just how

important they are in chemistry. (Timberlake, 2016)

A child asked a clerk, “How much is that lollipop?” The clerk responded that the

candy was worth “three.” The child’s father asked how far away the nearest

grocery store was. The clerk told the child’s father it was “twelve away from

here.”

Are units important in this example?

Yes, units are important in this example. The answer the clerk gave to the child and

father was a broad answer. It leaves a lot of room for misinterpretation of how much the

lollipop is and how far the nearest grocery store is. There is a high chance that the child

could assume that the lollipop is $ .03 cents or $3.00 dollars. He would either be paying

too much or not enough.

As far as how far the nearest grocery store is, this broad answer leaves the father’s

question unanswered. It is important that the clerk uses units to clear up any

miscommunication. This could leave the father thinking 12 meters, blocks, or minutes

away. The clerk failed to mention what she means is the nearest grocery store is 12

miles away.

What extra information would units give the child or his father to clear up any

ambiguity?

To clear up any misinterpretations the child’s father could ask the clerk to be more

specific on the responses she gave to both their questions. He could ask her if the three

would that be in dollars or cents? Also, what she means by “twelve away from here”. Is

that miles or meters? This would allow the clerk to clear up any misunderstandings of

units.

● Are units important in this example?

● What extra information would units give the child or his father to clear up any

Yes, units are very important in this example. The problem is the candy is worth “three”

what? cents, dollars? And the nearest store was “twelve away from here” twelve what?

Miles, minutes, seconds? Units are very important for people to have a better

understanding. Extra information such as minutes, miles, seconds, dollars would help

clear up any ambiguity which is why units are important.

A child asked a clerk, “How much is that lollipop?” The clerk responded that the

candy was worth “three.” The child’s father asked how far away the nearest

grocery store was. The clerk told the child’s father it was “twelve away from

here.”

Units are important in this example for a few reasons. The clerk did not specify to the

child what “three” is or what she means by three in terms of a unit of measurement. The

child does not know if the clerk is referring to three dollars or three cents. The child

cannot pay the clerk the amount he/she is asking for due to the unclarity of information

presented. The unit of measurement is very unclear. When the father asked how far the

nearest grocery store is the clerk responds by saying “twelve away from here.” That is

not enough information for the father to understand how far away it is. He does not

know if she is referring to twelve feet, miles, meters, etc. Extra information that units

would give the child or his father to clear up any ambiguity would be necessary for the

clerk to specify exactly the unit of measurement they need in order to understand what

he/she is talking about. The father and child cannot guess or assume the measurement,

so clarification would be needed.

In this scenario where a child and a father asked a clerk regarding the price of a lollipop

and the distance of the nearest grocery store from their location, we can analyze and

interpret that the units of measurements are very important in order to interconnect

values of that physical quantity. Imagine if the price of the lollipop that the clerk is

referring to is not in dollars and if the clerk is describing the circumference of the lollipop

as three centimeters instead of referring to the price, this will actually cause a major

confusion. Accordingly, this causes ambiguity since there are lots of units for the length.

If only the clerk provided the unit of measurement for the distance of the nearest

grocery store from their location, the father and the child will have an estimate in their

mind on how long they will need to travel; whether will they need to drive or is it a

walking distance.

Another example is when we go to the grocery store to buy cereal, there’s a tag on the

shelf that tells us the price per ounce of cereal so we can compare the cost of one

brand over another. Without a standard measure of weight, in this case an ounce, we

wouldn’t know exactly what we are paying for. People figured out that they needed

standards of weight and measure, as they are called, in the earliest of civilizations so

that everyone would understand what they were getting when they bought something.

However, not all quantities require a unit of their own. Using physical laws, units of

quantities can be expressed as combinations of units of other quantities. Therefore, only

a small set of units is required. These units are called base units, and other units are

derived units. Derived units are a matter of convenience, as they can be expressed in

terms of basic units. Different systems of units are based on different choices of base

units. The most widely used system of units is the International System of Units, or SI.

There are seven SI base units, and all other SI units can be derived from these base

units. The seven base SI units are: [Physical Quantity: unit symbol (unit name)] Length:

m (meter), Time: s (second), Thermodynamic Temperature: K (degrees Kelvin), Amount

of Substance: mol (mole), Mass: kg (kilogram), Electric Current: A (Ampere), Luminous

Intensity: cd (candela).

The base units of SI are actually not the smallest set possible; smaller sets have been

defined. For example, there are unit sets in which the electric and magnetic field have

the same unit. This is based on physical laws that show that electric and magnetic fields

are actually different manifestations of the same phenomenon.

As a summary, knowing the units of measurement that correspond with a number can

give us so much more information than a digit sitting there by itself. Units can: assist us

in solving a mathematical problem, especially in chemistry, where we can follow the

units to get to the answer, help us in showing another person the exact amount we

have, show which measurement system the person is using (i.e. metric or standard).

For this case, units are considered very important and crucial as they are the magnitude

of a quantity. The clerk did not specify to the child what “3” is and what she means by

three in terms of a unit of measurement. In this situation, the child would benefit if units

were used after the clerk said the store was “twelve away from here” and the lollipop

was worth “three”. The child would need to know exactly how much money the candy is

worth as well as the father who needs to know the distance to the grocery store. The

father could think the grocery store is twelve blocks away, where it is really twelve miles

away. Knowing this information is crucial for the two who are trying to purchase the

lollipop and trying to find a grocery store.

Hello everyone,

Yes, the units are important in this example.

When the child asked a clerk, “How much is that lollipop?” and the clerk responded that

it was worth three, the clerk didn’t mention three dollars or three cents. So mentioning

the unit of the measurement is very important.

Again when the child’s father asked the clerk how far away was the nearest grocery

store and the clerk responded it was “twelve away from here”, the clerk didn’t mention

whether it was twelve miles, meters or kilometers.

So without proper units, an answer becomes ambiguous and incomplete. With proper

units the value of a measurement is ascertained. Only if the proper units were

mentioned with the value, the child and the father would get the exact information they

need about the price of lollipop and distance of the nearest grocery store respectively.
