Transcript of Copy of Metric System and Conversion Webquest

Metric System Webquest
ntroduction
Tracking snow into your office, you hook your coat and hat on the back of the door. Grabbing a cup of coffee and your lunch you recline back at your desk, another day another case. You’re a little tired after that all night stake out in Meteropolis. Even sleeping in and starting your day at noon isn’t helping, but maybe the coffee will.

Once again the agency is busy with folks earning a living, fighting crime and loving it. Some days are easy, some days the job is demanding. Noticing the file placed on your desk, the hope of an easy day fades away, as curiosity, and then a smile takes its place.

Opening the file, you thumb through some police reports from a crime scene. Nothing unusual in the file, just a few notes and information about an item stolen from a local tech firm. There was no evidence left behind, no damage, and no breaking and entering. The last part of the report gives information about a widget, a specialized device the company produces.

Partridge Tech recently opened in town. They supply area businesses as well as homeowners with technological expertise and equipment, including specialized gizmos, widgets, and thingmuwutz. Partridge Tech also has a strange connection with a podcasting program called Geek!ed! With excellent knowledge in all types of computers and technology, the small business has been accepted fairly quickly by the close-knit community, where everyone knows everybody. But something is amiss in this quaint small town.

Looking through the pages of information and reports, you come to the heart of the case. Some time early this morning (while you were recovering from the stake-out) someone sneaked into Partridge Tech and made off with a pretty pricey widget. With an old fashioned small town community like this, what would someone want with that type of item? That’s not your concern at the moment, you need clues! The best thing to do is get out on the beat, question a few folks, find out what they know, and piece this puzzle together.

You finish your lunch and redress for the cold outdoor weather. Tucking the case file under your arm you prepare to head out for another day of CRIME FIGHTING.
Your Task…

Your task is to interview possible witnesses. Listen to what they have to say and take your notes. Later you can analyze the notes/data at the crime lab.

There are a few places in town to visit: the gas station, construction yard, and the tailor. At each stop you will learn a little about each suspect and what they saw earlier that morning. You will also have an opportunity to visit some websites dealing with metric measurement and conversion. Again, take notes, write down the information you discover in your Crime-Fighting data sheets.

When you are ready to begin questioning the possible witnesses, click the arrow in the lower right corner and head out into town. Don’t forget to head back to the precinct crime lab once you have your data, there are a few tools there to help you analyze the information.

CRIME-FIGHTER:

* Hit the beat.
* Question your witnesses.
* Learn about the suspects, keeping your data in your notebook.
* Visit website links on metric length, mass, volume, and conversions.
* Head back to the crime lab, analyze/decipher the data.



HERE ARE YOUR SUSPECTS:

Norma Knuckles
Armando T. Belly
Bea Sting
Angelica Butter
Sergio Celery
Time to hit the beat...

Take a look at the flyer for the Missing Widget that has been posted around town. This flyer includes a description of the missing widget. You will need this information in order to solve the case!

In order to find the thief you will also need to:

Visit the pages on length, volume, mass, and conversions.
Read the eye-witness accounts on each page.
Visit the websites on each page.

Remember, the safety of our fine town depends on your accurate collection of facts and conversion of
eye-witness data! Once you have uncovered the facts and found the thief, present the following information
to your Chief Inspector:

* A complete and accurate Crime Investigation Packet with facts gathered from websites.
* Complete and accurate Eye-Witness Conversions Worksheet .
* A colorful and factually correct Wanted Poster depicting the Widget-Thief.
Here are some facts about the robbery supplied by an eyewitness, Mr. Length, a clothing tailor. Read his testimony and
gather the facts, then visit the length websites below to gather more information to help you solve the crime. Remember, complete your Crime Investigation Packet and Eye-Witness Conversion Worksheet as you visit the length websites.
Mr. Length's tailor shop
tailorshop


Witness: Mr. Length, a clothing tailor

The Story: Looking across the old downtown street, you see someone exiting the local clothing store. As you
cross the street you notice the person is locking the door. As he turns to walk away he sees you and stops to
apologize. You introduce yourself to Mr. Length and explain that you aren’t a customer; rather you are
investigating a local robbery. Inquiring about the robbery Mr. Length is happy to help with your
investigation. Working with cloths, fabric and making alterations most everyday, Mr. Length is happy to give
you any information he can about the size of folks, what they were wearing and the type of material their
clothes were made of. You explain to Mr. Length that you simply need some information about any
objects that people were carrying.

Data Gathered: Mr. Length gives you the following information:

He has seen 5 individuals today.
He saw Norma Knuckles walking through the site with a widget that was about .05dam.
He saw Armando T. Belly walking through the site with a widget that was about 5hm.
He saw Bea Sting walking through the site with a widget that was about .005km.
He saw Angelica Butter walking through the site with a widget that was about 500mm
He saw Sergio Celery walking through the site with a widget that was about 5000cm
So exactly how long is a meter? Or a centimeter? Or a kilometer? It's good to have an idea of what each measure
stands for so you can estimate metric length. To get an idea of how to estimate length in the metric system check out
these website:

http://www.cimt.plymouth.ac.uk/projects/mepres/book8/bk8i17/bk8_17i1.htm
For practice measuring in centimeters, click the link below. You will see a red line and a centimeter ruler. Find the
correct measure of the red line in centimeters and click on the correct answer. The site will keep track of how many
correct answers you make.

Here are some facts about the robbery supplied by an eyewitness, Mrs. Mass, the crane operator.
Read her testimony and gather the facts, then visit the mass websites below to gather more information to
help you solve the crime.
Remember, complete your Crime Investigation Packet and Eye-Witness Conversions Worksheet as you
visit the mass websites.

Witness: Mrs. Mass, a crane operator The street construction site

The Story: You decide to take a walk over to a nearby construction site. As you
walk a little way off the street, you notice small steel structure being constructed.
Seeing that you are violating safety protocol, a crane operator comes out to see
who you are. As the crane operator approaches you, she takes off her gloves,
dusts them off on her jeans and stuffs them in her back pocket. She tips her hard
hat with a smile and introduces herself. Mrs. Mass listens to your questions over
the distant hammering and sawing coming from inside the incomplete building.
She tells you that besides her workers, she has seen only a few people in town
from earlier today.

Data Gathered: Mrs. Mass gives you the following information:

She has seen 5 individuals today.
She saw Norma knuckles walking through the site with a widget that was about 25dg.
She saw Armando T. Belly walking through the site with a widget that was about 250mg.
She saw Bea Sting walking through the site with a widget that was about 2.5cg.
She saw Angelica Butter walking through the site with a widget that was about 2500dag.
She saw Sergio Celery walking through the site with a widget that was about .025kg.

You thank Mrs. Mass for the information. As you leave she revs up her crane and lifts another 50kg beam up to the top of a steel beam structure. The abrupt loudness of the machinery startles you so much that you dart out of the work zone, wishing you had noticed the ‘hard hat’ sign on the wire fence when you first arrived. You head back to Town Hall.

Here are some facts about the robbery supplied by an eyewitness, Mr. Volume, the gas station
attendant. Read his testimony and gather the facts, then visit the volume websites below to gather
more information to help you solve the crime. Remember, complete your Crime Investigation Packet
and Eye-Witness Conversion Worksheet as you visit the volume websites.
Mr. Volume's gas station






Witness: Mr. Volume, Gas station attendant

The Story: Crossing the street you head over to empty gas station in town. Stepping into the state of the art ‘Gassed & Gone” store/station, you see Mr. Volume slurping a glurpy and smiling. You explain your situation to Mr. Volume, that you are looking for information about folks that were in town earlier today. He tells you that it’s been a very slow morning: cleaned the restrooms, restocked the hotdog warmer, text messaged a few friends, 1 glurpy and 3 chili-cheese foot-longs later here we are. Sucking air into the straw at the end of his second glurpy, he smiles and restates that his day has been slow; no customers. Not wanting to see you go, he happily suggest that the two of you (with glurpy and footlong in hand) sit down and review the surveillance tape of the pumps outside. He explains that you can see the pumps along with the sidewalk that lead next door to the town hall. Mmm… a foot-long.

With a foot-long and glurpy in hand, you sit in front of the surveillance camera monitor. Mr. Volume rewinds the tape until it goes dark, the time on the tape says 6:25am. As the tape plays forward at double speed, you finally see a few individuals walking along the sidewalk. In each case Mr. Volume slows down the tape and zooms in to get an I.D. Each person is carrying a widget, but the tape is too grainy to make out what exactly the widget is. Seeing your disappointment, Mr. Volume noses closer to the screen. With his daily activities involving the filling of large volume containers with glurpy goodness, he indicates how much glurpy could fit into the widgets each suspect is carrying.
Data Gathered: Mr. Volume gives you the following information:

5 individuals were seen on the video surveillance tape.
He saw Norma knuckles walking through the site with a widget that would hold about 150 mm3
He saw Armando T. Belly walking through the site with a widget that was about 0.0015 m3
He saw Bea Sting walking through the site with a widget that was about 1.5 hL
He saw Angelica Butter walking through the site with a widget that was about 15 cL
He saw Sergio Celery walking through the site with a widget that was about 15 dm3

After writing down the information, using the recently cleaned restroom, Mr. Volume tosses you a glurpie for the road. You thank him, wondering how many more miles you will need to jog tomorrow due to extra calories. You head back to Town Hall.
Definition of volume is the amount of space an object takes up.
Capacity is the volume inside a container.
A liter is the basic unit of volume.

A kiloliter is 1000 liters.
A hectoliter is 100 liters.
A dekaliter is 10 liters.

Head back to the precinct crime lab to investigate.

As the lead detective on this case, you have interviewed three expert witnesses: Mr. Length, Mrs. Mass, and Mr. Volume. These witnesses have seen all five suspects with a widget on the day of the robbery. Now it's up to you to find the robber from the line up of five suspects. Each expert witness has provided you with a cryptic clue. In order to solve the mystery, you will need to convert all of the clues into the following format:

Convert mass clues into grams (g).
Convert length clues into meters (m).
Convert volume clues into cubic centimeters (cm3).

The Metric County police chief is expecting your crime report turned in within 48 hours. Your crime report must include your completed Crime Investigation Packet, Eye-Witness Conversion Worksheet, and Wanted Poster for the robber.
Here are some helpful videos to demonstrate metric conversions.

View the following movie clips to learn more about converting between metric units of volume

Outstanding!! Sherlock could not have done a better job!

With your amazing conversion skills, or those that you learned along the way, you have identified
the dastardly thief. The would-be-widget thief is behind bars!

By this point you should have completed several tasks:
1. You know who the thief is.
2. You have completed the Crime Investigation Packet using complete sentences
with no spelling or grammar errors.
3. Completed the Eye-Witness Conversion Worksheet: all measurements
converted with correct units and calculations shown.
4. Created a colorful "Wanted" Poster.
5. Enjoyed the suspense!!


Double check to make sure all your information is organized and that you are prepared to
present your findings.

You return to your office, brushing off any snow on your shoes and dabbing a napkin to the corners
of your mouth (just in case that last foot-long left a bit of mustard). You check your calls, emails, and
glance across your desk; for tonight it’s clear. Who knows what tomorrow holds.
You grab your hat and coat and prepare to head home. As you switch off your office light, and close
the door behind you, you start to wonder what you will wear tomorrow and how those foot longs will
affect your sleep tonight. MMMMmmm foot-longs…
Length is measured in meters. We can say that the meter is the unit for measuring metric length.
Metric units are nice to work with because they are multiples of ten.
There are a lot of metric prefix units, but the basic metric units are milli-, centi-, deci-, deka-, hecto-, and kilo-.
Length can be measured in millimeters, centimeters, decimeters, meters, dekameters, hectometers, and kilometers.
However, the most common metric measures of length are the millimeter, centimeter, meter, and kilometer.

For examples of metric prefixes for units that are much larger than kilo- or much smaller than milli-, go to the link below.
