U1D3: Scientific MethodDo Now: 1. Take out signed materials. Cut off bottom portion of safety contract and staple to upper left of the goggle contract (ex on board)

2. Complete Parts 1-4 in Safety Lab: 15 minutes. (If you are done, you are in your seat working on the questions or re-reading p. 2-4)

Do you have all 4 stamps?

Today…I will be able to identify the different parts of a lab investigation in terms of the scientific method.

Emergency Procedures & lab wrap up

Vocabulary…

What is the scientific method?

POGIL: Fundamentals of Experimental Design

Practice with the scientific method.

HW discussion.

Homework

Lab Due: ………. (Check schedule)

Practice 1: ……..(Check Schedule)

What else should you be doing?.....

Emergency Drill Procedure 303Fire Drill; right out of the class, turn right go down the

stairs by the pool and out towards the announcers booth

Tornado Drill; right out of class to BLUE wing;

Lock down; go towards the eye-wash. Remain quiet

General rule of thumb, do EXACTLY as your told

Emergency Procedures (304)

Fire drill… (left, then right, down the stairs and out to announcer’s box walkway)

Tornado drill…left then right to BLUE wing.

Lock down… (front corner) SILENCE!

General rule of thumb; Listen carefully and do EXACTLY as your told

Vocabulary in ChemistryTake out your note packet with the vocabulary on front:

So..you’ve read p. 2-4, you highlighted one instance of each of the vocabulary words with Roman Numeral 1 (I).

1. Now… re-read the definition and the word in context.

2. On loose-leaf (or typed) write the definition of the word in your own words.

3. Repeat for each vocabulary word. This should be completed as you read so it will be completed a little at a time and ready to turn in Day 10.

What is the scientific method? Notes packet p. 2-4.

“Science is the best tool ever devised for understanding how the world works.” – Michael Shermer

Scientific Method:Models: developed to help understand the

world we live inRepresentations, physical or

mathematical, used to make predictions.Theories: models that stand the rigors of

peer review.

The Process:Observation: typically recurring

phenomenon.

Problem: observed fact; issue to be resolved i-Pod won’t play: observable by allDiagnosis: applying the scientific method to

determine why the i-Pod won’t work

Understanding the ProblemHypothesis: a testable statement

intended to lead to an experiment requires research of the scientific literature

to see what has been done before in pursuit of this issue.

states “IF we do this, THEN this should be the result BECAUSE (insert information gleaned from research here).”

• Variables: changed factor• Control: Every other possible factor

that may affect outcome

Testing the hypothesis.Experimentation:

Data: Measurements/information observed during the testData table: organizes data into an

easily readable formMeasurements: metric/SI system

Precise: smallest decimal position measurable

What to do with the data?Analysis: what is the data telling you?

Graphs: visual representation of data that shows the relationship between the independent and dependent variables.Direct relationship: Inverse relationship: No relationship:

Mathematical analysis of graph: ex. slope

Put it all together.Conclusion: a falsifiable statement that explains the

relationship between the variables that can be used to make predictions

Theory: model, either physical (like a map) or mathematical (equation “D=M/V”) that can be used to make reliable predictions.

There is no higher position a scientific idea can attain than that of theory.

POGIL:

Process Oriented Guided Inquiry Learning

 You will work in groups of 3 to complete an inquiry activity.

3 jobs:

1. Facilitator:

2. Spokesperson:

3. Quality Control:

What you think each role entails.

Understanding of Experimentation

So….What do we remember?

Lets look at the schedule…….

HW tonight:
