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?

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.
