Warm Up: Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they’re supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.
1. Control Group
Group B
2. Independent Variable
volume of special juice
3. Dependent Variable
number of stapled packs of paper
4. What should Smithers’ conclusion be?
The special juice interferes with the workers’ productivity since Group A stapled fewer packets than group B.
5. How could this experiment be improved?
Vary the volume of juice given, increase the sample size, take more time points, and conduct the experiment for a longer period of time.

–Warm Up: Cheating is the act of taking an unfair or unearned advantage, usually through deception. In academics, it most typically means taking unearned credit.
Your roommate is deeply depressed after a bad breakup. She’s a whiz at math, but she keeps forgetting about deadlines and getting further and further behind in the calculus class you’re both taking. In fact, she’s now missed so many homework assignments and quizzes that she’s failing the course (even though you know she’s more than capable of doing the work). You’re a B student at calculus, but you’re worried that she’s going to go from an A to an F, which will seriously hurt her chances of getting into grad school. You decide to submit a few of the homework assignments and online quizzes on her behalf. This is (justify your answer):
A. Clearly not cheating
B. Clearly cheating
C. Not exactly cheating but not exactly not-cheating either –Individuals: Read “NCAA penalties extend to 10 FSU sports” & RespondSmall groups whole group
*What were your feelings after reading the article? Why?
*Explain why the topic of this article is important.
*What questions do you still have about this topic?
*Did the Punishment fit the crime? Why or why not?

–Warm Up: “Cheating is on the rise,” reports expert Donald McCabe, a professor at Rutgers University. His surveys show that school dishonesty is a growing problem in every part of the country.” His and other studies report that 73% to 80% of high school students cheat. “What is the big deal about cheating? It’s only wrong if you get caught.” Do you agree or disagree with this statement. What should we do about cheating in the schools?

–Warm Up: Read the following scenario and select the response you think most accurately describes the situation.
Jessi and Brittani are best friends and have enrolled in the same biology course. Their biology lab is offered at two different times each week and students can attend whichever one is most convenient for them. Most weeks Jessi and Brittani go to the same lab so they can work together to complete the assignments. At the end of the semester, the TA announces that the final lab exam will be given at two different times on the same day and, as usual, students can attend whichever is most convenient for them. During the first lab exam, the TA notices that Jessi is there but Brittani is not. He also notices that Jessi is writing notes in her lab notebook as she takes the exam. Curious, he walks over after the exam and asks to see her notebook.
Is it academically honest for Jessi to take notes during the exam? Be sure to justify your answer (explain why or why not).

Warm Up: Make a list of as many lab safety rules & pieces of safety equipment that you can think of on your warm up paper. You have about three minutes. partnerWhole Group

–Small Groups: Why is safety in science important? Whole Group

–Individuals: Read lab safety rules & contract then, sign the contract. *You need the rules for tomorrows test!

–Lab Equipment & Safety Symbol PowerPoint Presentation: What are some pieces of safety equipment that are not shown in the picture?
Word splash with symbols-put word bank on the board (disposal, biological, open flame, thermal, sharp object, fume, electrical, plant, animal, radioactive, clothing protection, fire, explosion, eye safety, poison, chemical)

–Individuals: Lab Safety Posters: Each student is assigned a lab safety rule. Use a pieces on white copy paper to create a safety poster with 2” high letters, 3-4 colors, very few words, * one strong large picture. Think billboard!
