WarmUp

1
Warm-Up

• Using only words, write a procedure that tells
  the reader how to tie their shoelaces.
• Be detailed and specific!!!

2
The History of Rootbeer

• (And a little bit about Beer)

3
This guy drinks rootbeer and look what he can
do!!!
4
Biotechnology

• Biotechnology
• Bio means LIFE
• Biotechnology is the manipulation and alteration
  of LIFE to develop new processes and products.

5
The Earliest Biotech

• Biotechnology has been going on for THOUSANDS of
  years. The most recent Biotech involves the
  manipulation of DNA to change genes and create
  new proteins.
• However WAY before people even knew about DNA
  they were doing Biotech. This Biotech had to do
  with Food.
• Question What do you think were the first things
  developed with Biotechnology?

6
The first Beer(You dont need to copy this)

• Over 6000 years ago, a group of people known as
  the Sumerians discovered the process of
  fermentation and began to make a beer made of
  wild barley.

7
What is Fermentation?

• Fermentation is a process that yeast go through
  to break down their food. In the process of
  fermentation, the yeast consume sugar and produce
  Carbon Dioxide.
• Question How do you think the Sumerians
  discovered fermentation?

8
How does Fermentation Work?

• Yeast use sugar for energy just like we do.
  However, they can break it down differently
  depending on whether oxygen is present.
• If there is NO Oxygen, yeast will go through
  fermentation.
• Q What will we need to do to our rootbeer to
  make sure it goes through fermentation?

9
The invention of rootbeer(You dont need to copy
this)

• In the mid 1800s, many pharmacists made cure-all
  remedies that were supposed to treat all sorts of
  medical problems. Some of this cure-alls had
  recipes very similar to rootbeer. They were made
  of roots, spices, and other secret ingredients.

10
The Godfather of Rootbeer(You dont need to
copy this)

• A man named Charles Hires found one of these
  recipes that he really enjoyed and began to sell
  a packaged version as a tea.
• This tea was well received and the Hires family
  soon began selling a bottled and carbonated
  version. This was one of the first sodas ever
  sold.

11
Rootbeer Today

• Most Rootbeer today is made with artificial
  flavors and carbonated using machines that inject
  Carbon Dioxide gas.
• We are going to make Old School Rootbeer we
  will use yeast to carbonate our root beer.

12
Designing Writing-Up a Lab

• It is very important to follow the proper steps
  for writing up a lab in your notebook. This
  ensures that you and others will be able to
  easily understand what you did and reproduce your
  experiment in the future.

13
Title

• ALWAYS title your experiment. Your title should
  tell the reader exactly what your experiment is
  about. It should be complete and concise.
• Q What would be an appropriate title for the
  rootbeer lab?

14
1. Background

• The background section is where you state all the
  important information that will help someone
  understand the lab. For instance, in the
  rootbeer lab well write down what fermentation
  is and what is has to do with rootbeer.
• NB We are doing this RIGHT NOW

15
2. GOALS

• You should always clearly state the goals you are
  trying to accomplish. Your goals should include
• QUESTION What are you trying to learn?
• HYPOTHESIS and/or PREDICTION What do you think
  is the answer to your question?

16
Good Questions

• A GOOD scientific question is TESTABLE.
• This means that you can design an experiment and
  collect data that will help answer your question.

17
Variables

• You will always need to select one variable that
  you will change in your experiment. This is your
  independent variable.
• Changing the independent variable can cause a
  change in some of your results. This change that
  your observe is your dependent variable.
• Always state both variables in your lab.
• Q What could be some ind. Variables for the
  rootbeer lab? What would the dependent variables
  be?

18
3. Procedure

• Your procedure section should include two
  subsections
• A. Materials a list of everything that you
  will be using, including the proper amounts
• Protocol a step-by-step description of how you
  will carry out your experiment.
• Q What would be the materials for the yeast
  balloon lab? What would be a simple protocol?

19
4. Data and Observations

• In this section you record all your measurements,
  observations, calculations, and any other
  important information that comes from your
  experiment.
• All information should include labels and
  appropriate units!

20
5. Calculations and Graphs

• Using your data, you should make an appropriate
  graph that visually represents your results.
• Any necessary calculations should be clearly
  shown so that someone else could repeat your
  procedure.

21
6. Conclusion

• For your conclusion you should include the
  following look in your rubric!!!
• Results with Evidence and Explanation
• Possible Errors and Explanation
• Practical Applications/Next steps

22
Dont try this at home
23
An interesting note
24
Your task

• In your group, work together to come up with 5
  testable questions you could ask about rootbeer.
  
• For each question, state a hypothesis and the
  independent and dependent variable.
• Everyone should have their work written in their
  lab notebook.
