Bellwork 8/30/04-8/31/04

• Take a folder and write your LAST NAME then your
  FIRST NAME on the tab at the TOP of the folder.
• Place your Student Info Sheet and Safety Contract
  inside of the folder and leave it open!!!! I
  need to see it in order for you to do the Lab
  today!!!

2
Scientific Method

• Today we will be exploring the scientific method.
• As a team, I would like you to write down the
  steps to the scientific method. This is a
  brainstorm, write down the steps you can think
  of, and a description of each.

3
The Scientific Method

• is an organized way of figuring something out.
  
• There are usually six parts to it.

4
Steps?

• What steps did you come up with?
• What does each step involve?

5
Step 1 Question

• All science begins with a question.
• Something is observed in the natural world, and a
  question is formed.
• Example Why do some plants grow better in the
  shade than in direct Sunlight?

6
Step 1 Question

• A question can also be thought of as a purpose.
• You are curious about something, and want to
  learn more about it.
• Example "Do plants grow better under different
  colored lights?"

7
Step 2 Research

• Having a question about the natural world, you
  now should research it.
• What have other scientists found out?
• What information is available?
• Where should you look?

8
Step 2 Research

• Sometimes you will find your question already has
  an answer.
• Other times, the answer is not apparent or little
  is known.
• This is when you begin to think about how to find
  your own answer.

9
Step 3 Hypothesis

• After doing your research, try to predict the
  answer to the problem. Another term for
  hypothesis is 'educated guess'. This is usually
  stated like " If I...(do something) then...(this
  will occur)"

10
Hypothesis Example

• Example
• "If I grow plants under green lightbulbs, then
  they will grow better than plants growing under
  red lightbulbs"

11
Step 4 Experiment

• The fun part! You have researched your topic,
  came up with a hypothesis and now must design a
  way of a way to answer your question.
• Any experiment is a test, through procedures, of
  your hypothesis.

12
Step 5 Analysis/Observations

• Record what happened during the experiment. Also
  known as 'data'.
• Observe what happens, record the data, then
  analyze the data.

13
Step 6 Conclusion

• Review the data and check to see if your
  hypothesis was correct. If the plant under the
  green lightbulb grew better, you proved your
  hypothesis, if not, your hypothesis was wrong. It
  is not "bad" if your hypothesis was wrong,
  because you still learned something!

14
Quiz, Quiz, TRADE!

• Were now going to do a quiz activity!!!
• The cards I will be giving out are to be returned
  afterward.
• DO not destroy these cards, please! -)

15
Lab for Today!

• Today's lab will ask you to make
• observations, ask questions, and
• to write procedures for the lab
• itself.

16
Background

• You are a geologist asked by the local government
  to determine if COAL is present in a tract of
  land outside of town.
• You will need to make a sketch of the surface and
  determine 3 sites to drill at.

17
Your Report Page

• Top right corner Name, Period, Date
• Top 1/3rd Observations
• Middle 1/3rd Procedures
• Bottom 1/3rd Data
• Back Report to be given to the town, paragraph
  minimum on what you found.

18
Observations

• On your own piece of paper, sketch what the
  surface of your land mass looks like.
• Write down any details next to your drawing.

19
Questions

• You need to pick three spots on your land mass to
  drill at. You will be drilling with a section of
  straw. Pick three spots where you as the
  geologist think you will get the best core sample.

20
Procedure

• After your observations you need to label the
  next part of your report, Procedures.
• As a team, talk about HOW you will gather your
  core samples what method would be best? (plunge
  straw straight in and out? How fast, how slow?
  Should you twist the straw?)
• Write down in order the steps you will take to
  obtain samples.

21
DRILL

• Now it is time to DRILL!
• You need to acquire 3 core samples.
• You need to be able to examine these samples
  after drilling.
• Tip After taking a sample, blow it out of the
  straw onto your paper towel, GENTLY!!!!

22
Data Collection

• You now have 3 core samples.
• Examine each one, what colors are present?
• How will you record your data?
• You know that Yellow is Limestone, Red is
  Shalestone, and Blue or Green is COAL.
• (Write these down on your sheet)

23
Analysis

• You should make a sketch of each sample,
  indicating the color of each.
• Label each layer as to what it is.
• Write in roughly what percent of the sample was
  what type of rock. The sample was a 1/3rd
  Limestone.etc

24
Report

• After figuring out what the various layers were
  in your land mass, you need to make a brief
  report.
• On the back of your paper, label a section
  Report.
• Write a paragraph about what you found in the
  tract of land.

25
Report

• What was present?
• What percentage of the core samples were
  Limestone? Shale? Coal??
• If the samples showed at least ¼ deposits of
  Coal were present, recommend for the town to
  drill for Coal.

26
Turn In Report

• In the upper right hand corner be sure your First
  and Last name is on the report, as well as the
  day, period and date.
• Example Joe Bob
• Maroon 1
• 8/30/04
• This is our procedure for assignments

27
Place in team folder

• Each team has its own folder, all assignments
  turned in will always be placed in the team
  folder. Be sure you know which team you are.

28
Team Folder

• On the front of the folder is a , this is your
  team .
• Each class period, the first person in the room
  should get this folder from the gray file box.

29
Returned Assignments

• All work I grade will be in the team folder.
• I NEVER remove any papers from the folder! From
  the moment you turn them in, they always stay
  with the folder.

30
Turn in Team Folder

• Now we will turn in the team folder. Today
  person 1 will take the team folder to the gray
  crate, and place it inside of the green hanging
  folder for your class.

31
Popcorn

• We will now answer some questions about what we
  did today.
• Take a moment to discuss with your team what we
  covered, be ready to be called on in a moment.
