WARM-UP
Dimensional Analysis Practice Quiz
1. How many millimeters are equivalent to 1.257m? Show your work.
2. Joe Average takes 20 seconds to make a double double cheezeburger. Each burger has three pickles. How many pickles will he use in an 8 hour shift?
3. For problem number 2, what if seven out of every ten burgers have pickles on them. How does that change your answer?
4. 2.54cm=1in How many mm are present in 20.0in?
CLASSWORK

HOMEWORK
Lab 1: Complete Part 4 (the rest should already be done). Submit via photo on GC.
Data for Plotting Graphs: Graph both sets of data. Bring to next class
Note: I will post answers to the Day 4 conversions HW this Sunday. Review to ensure you understand to concept. Here's the LINK (scroll to the last couple pages to see solutions)
Dimensional Analysis Quiz next class
Period 1 only: On Monday, I'll miss the 1st half of class (my 2yr old has his first day of preschool). See you around 9:15. You'll have your quiz in place of the warm-up, and then work on plotting your graphs on Google Sheets. Have fun!
WARM-UP:
1. How will your cookies be evaluated?
2. What will you do with your evaluations?
3. Will your cookies not suck?
Goals:
1. Groups will be able to use collected cookie data to analyze success of cookie design
2. Through creating their lab report, group members will become familiar with the format of a typical lab report
Cookie Testing
There are 7 groups in the class. Each student should sample a cookie from the other 6 groups and fill out a cookie analysis form. Those forms are given to the group who made the cookies so that they can be included in the group's data section.
Analysis
Teams will gather the analysis forms and make a data table that looks like this.
Enter the number of forms that answered too much sweetness in the box. Then enter the number of forms that answered balanced, etc. Each team will write three analysis statements based on the data in the table. Analysis statements should follow the format
Our data table shows _________________, so we conclude _____________________.
example: Our data table shows that 24 students thought the cookies were too salty, so we conclude that our salt calculation was low.
Lab Report Pieces
Abstract: Students will write out what type of cookie they wanted to create. How did you hope the public would react to your cookie? What kinds of things did you do during the experiment to make your cookie experiment successful?
Materials: What items are needed to perform this experiment? Include the converted version of your recipe here, complete with secret ingredient.
Procedure: These are the step by step instructions for carrying out the lab. The procedures should be so detailed that if another student read them he could conduct the lab from these instructions and get the same results.
Data: Any observations made during the lab should be recorded here. If the mixture turned a different color, or if bubbles were seen, or anything else, it should be written down. You should also summarize the feedback you received when other students sampled your cookies (you can do this with a chart or graph).
How did the public like them? Be specific. Also, this is the place to include pictures taken during your experiment.
Analysis: This is where you react to the feedback from the public. Did you make any mistakes during the conversion process? Did you make any mistakes following the recipe? Discuss how satisfied you are with your choice of secret ingredient. This section must include at least 3 analysis statements.
Conclusion: Your conclusion will be in the form of an advertising slogan. Write a slogan that accurately describes the strengths (if any) of your cookie in a creative and catchy way.
- Before the end of the period, take the pass to go get a piece of poster paper from the hallway next to the main office. They're out of basic colors - be excited to choose from interesting colors such as, "salmon", 'brown", and other favorites. Your paper should approximately be the size of one of the desks in this room.

Warm-Up.
Use the poster rubric to evaluate the following poster:
Large clear title. Catchy slogan. Data is listed in bullet point format (no table). No pictures. two correct analysis statements. Materials section has three math errors. Procedure has steps to make cookies. Poster is a decent advertisement, and sorta makes me want to eat their cookies. Here's the rubric: LINK
Poster Preparation
Mr. Alexander will put the rubric for the poster on the projector. It is also available here. Use the provided construction paper and finish your poster with your team. Display the poster when it is finished on one of the lab tables.
EDIT: This part took forever with all the Pep Rally absences, schedule changes, and some folks not reading project instructions correctly (result=poster components had to be redone). As a result, the portion in italics below will be pushed to Tuesday the 25th.
Poster Walk and Evaluation
Walk around the room and view the other posters. Your group is going to critique each poster. Take a sheet of paper and rank the posters according to the rubric. You must justify each ranking with a short paragraph that cites the rubric. If your group finds a math error on another poster and correctly fixes it (show work) then Mr. Alexander will give your team extra points. Submit your group's evaluation paper to Mr. Alexander.
Peer Evaluation
You will be evaluating the other members of your team in terms of their contribution to the project. Do this by yourselves and do not share your evaluation with the group. Once you have evaluated each other member of your group, submit your evaluations to Mr. Alexander.
Quiz (Dimensional Analysis, Conversion Factors, Analysis Statements)
