1.

Before you do this Quizziz, you need to upload a pdf of your cat lab packet to Canvas (showing that you did your homework). If you have not done that yet, stop the quizziz now and do it (and then do this quizziz).

a)

I have uploaded pdf of my homework (or emailed it to Ms. S if I had tech trouble)

b)

Please choose the other one.

2.

Be sure you used your real name in this Quizziz so that you can get credit for completing it (completion grade). If you didn't, stop now, exit, and then start over again with your real name.

a)

OK, I am using my real name

b)

Please choose the other one (let it be true).

3.

Every question in this quizziz has 3 minutes to answer, so that you have plenty of time to think & refer to your packet and make corrections as needed. You can use the PAUSE button (upper left) as needed to see correct answers for longer, and at the end, you can review all the questions and answers.

a)

OK, I will make any needed corrections in my packet. If I don't understand something or still have questions, I'll make note to ask Ms. Sanders about them later (via email, in class, or tutorial)

b)

Please choose the other one (let it be true).

4.
