Scientific Method
IDENTIFY THE PROBLEM
Science is not linear process...
REPORT YOUR RESULTS
COLLECT INFORMATION
RESEARCH
BEST GUESS TO THE PROBLEM
FORM A HYPOTHESIS
TEST YOUR HYPOTHESIS
EXPERIMENT
CONCLUSION
ANALYSIS
Wrap it Up with....
What is....
It is the
process
that is used to find
answers
to questions about the world around us.
Is scientific method the only one?
No, there are several versions of the scientific method. Some versions have more
steps,
while others have only a few. However, they all begin with the identification of a
problem
or a
question
to be answered based on observations of the world around us and provide an
organized
method for conducting and analyzing an experiment.
An
educated guess
based on observations and your knowledge of the topic.
It is the
information
gathered during the
DATA:
START HERE
what do we want to know?
use observations you have made to write a question that addresses the problem or topic you want to investigate
Example: I wonder what it is that causes rainbows in the sky?
Find out what you can about your observations already.
internet
library
teacher
articles
Predict your answer of what you think will happen.
Does not have to be right or wrong!
Rainbows appear as a result of water in the earth's atmosphere "bending" the light from the sun.
Create an Experiment
How will you test your hypothesis? Develop a procedure for a reliable experiment and address safety rules.
Record data and observations!
Follow your steps....
Perform an
Analyze the Data
Does it support your hypothesis?
NO
YES
NO
YES
Is your data inaccurate or the experiment flawed?
Communicate the Results
Modify the Experiment
Rewrite your procedures to fix the flaws in the original experiment
Write a summary of the important parts of your experiment and results
Good Morning! Sept. 4, 2012
Please prepare yourself for a busy day. Hand in your homework in the proper tray and get writing.
wRiTe DoWn...
Essential Question
: How is scientific knowledge generated and validated?
wRiTe DoWn & AnSwEr
Get Going
: What makes a hypothesis testable? Please list an example.

Remember to follow directions and stay on task.

See White board for graphing procedures.

Good Morning! Sept. 5, 2012
WrItE DoWn & AnSwEr
Get Going: Please answer the following questions about the data you collected in lab.
1) If construction paper weighs more, should it have flown further than the printer paper airplane? What could have happened in your lab that caused the printer paper to fly further?
2) Many of you had different numbers for the same type of paper. Why do you think the numbers were not similar?

Please turn in your homework in the paper tray
* Lab worksheet
* Come Fly with Me Lab
* Science folder
facts, figures, and other evidence gathered during observation.
Example: During the Airplane Lab you measured the distance it traveled in inches. You interpreted the data into a bar graph so it was easy to read.

What's the difference between Qualitative and Quantitative Data?
Measured data
length
how much in liquid
amount/number of item
What you observed/ noticed but not measured.

Example: Gummy bears got sticky - you did not measure sticky
Quantitative
Qualitative
candle
lit candle

Welcome to another busy day! Sept. 5, 2012

WriTe DoWn:
Essential Question: What is the standard world?
WrItE DoWn & AnSwEr:
Get Going: What is the standard measurement system used by scientists around the world?

Please turn in your homework in the paper tray.
The Metric System
1970's : universal system of measurement developed in France
-measurement system based on the number 10.
The International System of Units (SI)
a modern version of the same metric system to include:
length, volume, mass, density, temperature, and time.
helps scientists across the world compare results/data.
Length:
basic unit = meter
[cm] = 1/100
[mm] = 1/1000
[km] = 1,000 m
short distance
long distance
Mass:
basic unit is the kilogram (kg)
smaller objects - use grams
Triple Beam Balance
3 feet = roughly 1 meter
Look at Appendix E in your book for step-by-step instructions pg 878
Weight:
http://www.onlineconversion.com/weight_on_other_planets.htm
is the measure of the force of gravity acting on an object. This force changes from place to place.
Your mass stays the same everywhere you go, but your weight changes.
Volume:
The amount of space an object takes up.
Liquid: use a graduated cylinder [mL]
Solid: [Regular] length x width x height = cm
3
[Irregular] immerse in water
v - v = vol. of object
water + object
water
basic unit = liter
Density:
measure of how much mass is contained in a given volume.
Formula:
Mass
Density = -------
Vol.
Expressed as g/cm or g/mL
3
Temperature:
basic unit used is Kelvin
0 K = -237 C
o
o
Coldest temperature ever!
[Nothing can get colder than this temperature called Absolute Zero]
Does NOT have any negative #s
Time:
basic unit is seconds (s)
Let's try: Convert 3 minutes into seconds
60 seconds per minute
Let's Try : How many Kelvins are in
(a) 25 degrees Celsius
(b) 35 degrees Celsius
Find the density of a box that has height 1 cm, width 5 cm, and length 5 cm and a mass of 50 g.
L
Find the volume of the box to the left
If the length from home plate to first base on a baseball field is 90 feet, how many meters would that be?
Thankful Thursday! Sept. 6, 2012

Get Going: Today you have a quiz. Start studying your science folder and the safety signs in the front of your science book. Remember what we have gone over continuously in class about how to conduct yourselves in the lab.
What is a quiz?!

This is the time to be silent. I will verbally not tell you this because you are responsible young adults.
When you are done bring the test to my desk and put your head down at your seat. We will wait for everyone to finish.
Video on the Scientific Method - Please take notes
TGIF! Sept. 7, 2012

Get Going: A hypothesis is a statement that predicts what will happen. For instance, you installed your own ceiling that has a remote. The remote can control the turning off and on the light and the speeds of the fan. For the first few months it has worked perfectly. You get into a routine of going to bed, shutting the light off with the remote and placing it on the floor. Recently, the light has been turning on its own in the middle of the night and the fan has been changing speeds.
Write a hypothesis predicting what could be the problem. Make sure it is a statement and not a question.
