Wednesday
Basketball Bragger:
Mr. Anderson. plays basketball on Thursday night with his friends. To practice, he occasionally plays with his nephews, who
are in 4th grade. Against the 4th graders, Mr. Anderson averages about 40 points per game. Last year, Kobe Bryant averaged
about 27 points per game playing in the NBA. Because Mr. Anderson averaged more points than Kobe, he claims that he is a
better offensive basketball player than Kobe.
1) Is this a valid test? Do you agree with Mr. Anderson’s claim? Why or why not?
Controls:
In an experiment, there are often ____________________________________ two variables.
To make sure that a test is only exploring the relationship between TWO of the variables, all of the other variables
have to ____________________________________________________
This is called ________________________________________ for a variable; a control is something that has to stay the same
during an experiment in order for the experiment to have _____________________________________________________.
3) What are some variables that you would have to control for in order to make Mr. Anderson’s claim more valid?
There are lots of them.
A Little Practice:
1) Aaron’s batting average is .770 in his Little League. He is better at bat than Major League players.
This experiment does not control for…
2) Beyonce scored a B+ in her math test, and Jay-Z scored a C- in his English test. Therefore, Beyonce is a better
student than Jay-Z.
This experiment does not control for…
Part 2: Below are a series of conclusions that were made based on tests or experiments. Explain what you would
HAVE to control for in order to make the conclusions valid.
3) Derek took three minutes to get to her class; Elizabeth took two minutes to get to her class. Therefore, Elizabeth
walks faster than Derek.
In order for this conclusion to be valid, the test needs to control for…
4) Felicity smells terrible and Grant smells wonderful. Therefore, Felicity showers less often than Grant.
QUIZ- 80 OR BETTER MEANS WE ARE ON TRACK TO BEING EXCELLENT!
Thursday
1) What is the question that your experiment is trying to answer? HINT- look at the project description.
2) Form a hypothesis about the outcome of your test. Which set of pants do you think will resist stains better?
3) Identify the independent and dependent variables in this experiment.
IV: _______________________________________________________
DV: _________________________________________________________________.
4) Identify at least 2 things that you will need to control for during your experiment:
5) In the space below, write your group’s procedure. This is EXACTLY what you will do during your test. Any other
group should be able to read this procedure, follow it exactly as it is written, and reproduce your experiment
perfectly. Think of it like a recipe- anyone who reads your cookbook should be able to reproduce the meal.
6) In the space below, list all of the materials that you think that you will need to perform your test. Be as specific as possible.
Friday
Lab Day!:
You have all of today to perform your procedure and to answer the following questions.
1) In the space below, record your observations and data in a coherent fashion. For example, you can use tables or lists to record
your information. This means that anyone should be able to look at your results and understand what happened in your
experiment. Think of it like the bill at a restaurant: anyone should be able to look at it and know what you ate and how much it
cost.
2) Based on your data, answer the following questions to make your recommendation to NanoTex:
a) Which material, the nano-fabric or the regular fabric, was most resistant to being stained? Explain your
answer using a specific example from your data.
b) This technology makes clothing approximately twice as expensive due to the costs of researching this
technology and safely implementing it in clothing. Based on your results, do you think people would be
willing to pay almost double to wear these clothes?
c) Regular pants cost approximately $25. How much would YOU be willing to pay for the pants made with
nanotechnology? Why?
Homework: FINISH LAB REPORT AND YOUR ACHIEVE 3000 ARTICLE. Achieve 3000 can only be accessed during
school hours, so if you don’t finish it in class you need to go to a computer lab during your lunch period.
