III. The Scientific Method

Scientific Method: steps that scientists use to gather information and answer questions.

1. Question/Observation/Problem: noticing something that nobody has noticed before

“People trip a lot at Central.”

2. Hypothesis: an explanation for a question or an educated guess.

“If students walk on our wood floors, then they will stumble more often than on other surfaces.”

3. Experiment: an investigation that tests a hypothesis by collecting information under controlled conditions“Today, I will count how many people stumble on the wood floors each passing period.”

a. Control: the group in which all conditions are kept the same“Tomorrow, I will count again at the same time, but in the basement where the floors are concrete.”

b. Independent variable: condition that is changed

The surface that students are walking on (the cause).

c. Dependent variable: condition that changes due to the independent variable.

Whether or not people trip (the effect).

d. Data: information collected from the experiment

Scientific Method Cont.4. Conclusion: reporting of experimental data

5. Theory: a hypothesis supported by a large body of evidence

“I did the experiment every day for a month and the results were always similar. I believe the wood floors here make us TRIP.”

BellRinger 9.6.2013Me’Shell predicted that vitamin water would help zombies get stronger. She kept two zombies; one got regular water and one got vitamin water.

1. What is the control?

2. What is the Independent variable?

3. What is the dependent variable?

Zombie w/regular water

Vitamin water

Zombie strength

Bellringer 8/25/101. List the steps of the scientific method in

order.

2. Describe the difference between an independent variable and a dependent variable.

Writing a Lab Report1. Title: What is the experiment about

2. Purpose: WHY is the experiment being performed?

3. Hypothesis: predict the outcome; educated guess.

4. Materials: what was used in the experiment

5. Procedure: “Recipe Style” directions of how to perform the experiment.

Writing a lab report (CONT.)

6. Organize Data: report quantitative and qualitative data

7. Conclusion: brief summary of the data and an explanation of whether the data supports the hypothesis.

Bellringer 8/27/101. In the heart rate experiment what data did

you collect?

2. In the toothpick tower experiment what data did you collect?

3. Why is data collection important when performing an experiment

Heart rate or bmp

Height of the tower

Helps to form a conclusion and show evidence

IV. Types of Information1. Quantitative Data: numerical or

measurable data, usually expressed in graphs or tables

SI Units: universal-measuring units used to report quantitative data

a. Meters= length

b. Gram= mass or weight

c. Liter= volume

d. Second= time

e. Celsius degree= temperature

2. Qualitative Data: written descriptions of what scientist observe

Graphing review1. Where is the X-axis?

2. Where is the Y-axis?

3. What is a line graph?

4. What is a bar graph?

Bellringer 8/31/091. What is quantitative data?

2. What is qualitative data?

3. Why are SI units used in collecting scientific data

Numerical data ex. 20 cm

Descriptive words ex. Purple, soft

SI units are universally understood around the world

V.Rules of Graphing Scientific Data

1. Title the graph: Tree species VS height

2. Label the axis:

• X-axis is the horizontal axis

Contains information related to the independent variable, example tree species

• Y-axis is the vertical axis

Always contains numbers , example tree height

Tree Species VS Height

Height

Tree Species

Rules of Graphing Scientific Data (CONT).

3. Number the axis: first look at the data table and round the largest number to the nearest 10th place

50 m

4. Count the number of boxes

on the graph paper for that

axis

10 boxes

5. Divide the number in step 3 by the number in step 4 to get the value for each box on the graph paper

50 ÷ 10 = 5 m

Trees height

Elm 48 m

Maple 35 m

Cherry 6 m

Bellringer 9/1/091. When is graphing useful in science?

2. Sketch a graph and label the following

a. X-axis

b. Y-axis

3. Why is it important to label the x and y axis correctly?

Y-axis

X-axis

For organizing and interpreting numerical data
