CASE’S QR QUEST

There are 15 QR codes that I have generated and placed in the

designated area. Your group will find as many as you can and

complete the quest embedded within the QR code. Most are just

genetics questions that your group will answer (some are more

challenging than others). One is a link to a website that you will

visit and answer 2 questions from, one is a video assignment, and

one is a bonus …just because you all know how much I love you!

This is how the QR Quest works:

1. To start: Pull up Edmodo and DM me with your group

members’ names.

2. You will find a QR code card and scan it using your app.

It may take a bit of focusing and centering and getting the

light just right. See me if you have a problem.

3. The scan will immediately provide the message I have

hidden for you.

4. Work out the problem (or challenge). Also, write out

how you completed the challenge, showing your work.

You will turn this in at the end of the period. Make sure all

members’ names are on it. You may use your textbook if you

need to look anything up.

5. After completing all 15 quest challenges, pull up Edmodo and

DM me the numbers of the QR ( this will be 1-15 written

on the paper) and your answers (most will be a multiple

choice letter or short answers) For the video challenge you

may just DM “we did it”

6. GOOD LUCK!

This activity was created 2011 by Mrs. Robbie Case at Tuscaloosa County High

School using questions on the Biology Project>>Mendelian Genetics website at

http://www.biology.arizona.edu/mendelian_genetics/mendelian_genetics.html. It

has been posted with permission.

Here are the rules and they will be STRICTLY enforced:

1. You may never go to a QR if a group is already there. Either find

another one or wait a far distance away.

2. You may NOT speak loudly or misbehave. You will only use a

voice that your group can hear. Keep conversation to a

minimal. A portion of you grade will be based on your behavior

and if one member loses points….you all will! One reprimand of

any group member will result in 5 points off your grade. If

you are reprimanded twice…..YOU ARE DISQUALIFIED! I

know it will be exciting different and fun, but be mature,

responsible and VERY QUIET!

3. You may only use your smart phone for SCANNING the QR code

and reading the challenge or going to Edmodo to submit your

answers. No other use of the cell phone is allowed. You will not

use sound so keep it on silent. Remember to turn it off and put

away at the end of the period.

4. Be smart and savvy…get as many of the challenges as you can on

the quest. You must submit answers by way of Edmodo DM for

them to count!!

**Mrs. Case reserves the right to add any to or change any rules

during the quest. Since this activity is brand new, adjustments

may have to be made….and that is Mrs. Case’s decision to make!!

You guys are making history…..it has never been done here

before!** Good Luck!

These are the encoded quests for each QR code.

All of the genetics questions were taken from the online quizzes from the site below:

http://www.biology.arizona.edu/mendelian_genetics/mendelian_genetics.html

The following 15 pages are the QR Quest Cards

that you will post in the designated Quest area.

It is best to post them in a well-lit, very large

area where you can observe all students. Also

post the cards about eye-level.
