Chapter 2 Lesson 2
Thinking like a Scientist

2. My Planet Diary
Do you think it is helpful or harmful for a scientist to be curious?
Curiosity allows a scientist to discover new things.
The more questions scientists asks the more things are investigated, which will lead to further discovery.
When investigating you must cautious to eliminate your bias in order to reach the desired outcome.

3. Fill out the communicate section of page 14

4. Scientific Attitudes LEARN THESE ATTITUDES!!!
Scientists possess certain important attitudes, including curiosity, honesty, creativity, open-mindedness, skepticism, good ethics, and awareness of bias.
LEARN THESE ATTITUDES!!!

5. Curiosity
The desire to learn and know more about topics, ideas, and your surroundings.
To wonder about things.
Are you a curious person?
How is being curious a beneficial trait?

6. Honesty What is involved in honesty?
Telling the truth.
Having people believe what you say.
Scientists must report the results of their investigations with honesty.
Scientists cannot falsify their results to reach a desired outcome.
Without honesty, a scientists observations and findings cannot be trusted by others.

7. Creativity What is creativity?
Solving problems and doing things in your own way.
Thinking outside of the box to find a solution.

9. Open-mindedness and skepticism
Science is always changing and evolving.
Scientists must always keep an open mind and the ability to accept of new and different ideas.
Scientist should be willing to accept new ideas but always be skeptical
Skepticism involves having doubt
Asking for proof before accepting
new things as truth
Talked about Pluto being a planet when I was younger and how its no longer considered a planet in our solar system.

10. Skepticism cont.
If I were to tell you that a tomato is a fruit would you believe me?
Yes, no, maybe?? This questioning is considered skepticism.
No? You may say a tomato is a vegetable because I eat it on my salad and a tomato is not sweet like fruits.
If I were to tell you that scientifically tomatoes are fruits. All produce that contains the seeds internally and originates from the flowering portion of the plant is considered fruit.
Does this information change your opinion?

11. Ethics Rules that enable people to know right from wrong.
Research and investigations can come with a lot of effects on people and environments.
These effects begin can be both good and bad.
What can happen if a scientist does not practice good ethics?

13. Bias
When what you expect to observe influences the interpretations of observations.
What you think you already know about something leads to misinterpretation.
Three types of bias
Personal bias (personal likes and dislikes)
Cultural bias (Culture in which you grow up)
Experimental bias (Mistake in experiment design)

14. All rocks are the same Bias Wall They look different from me!
All southern boys are rednecks
Florida is the best state
Science is only for nerds
All rocks are the same
Inches are the same as milli-meters
Green food is gross
Only boys can be athletes
They look different from me!
Build the wall and talk about how everybody has bias. We must be aware of these bias and try to break down the wall so we can see clearly.
NO BOYS ALLOWED
GIRLS ONLY
Americans
are the best

15. Scientific Reasoning
Scientific reasoning requires a logical way of thinking based on gathering and evaluating evidence.
Two types of reasoning: inductive and deductive
Which do you think is more likely to result in valid information using emotions and stating opinions or using scientific reasoning?

16. Objective Reasoning
Making decisions and drawing conclusions based on available evidence.
Relies on gathering and evaluating data to reach a conclusion.
Using data along with observed and collected evidence to reach a conclusion.
SCIENTIFIC THINKING!!
Using the scientific skills we discussed in lesson one to think.

17. Subjective Reasoning
When personal feelings and opinions are included in the decision making process or to reach a conclusion.
Based on the feelings you have about something.
Non-scientific thinking. No evidence needed, just feelings.

18. Deductive Reasoning
Explaining things with a big idea first then applying that idea to a specific observation.
Example:
Big Idea: The suns rays are most direct and therefore strongest at noon.
Reasoning: Noon will be the hottest time of the day with little to no shadows. I should try to stay inside and hydrate.
Think subtracting…. Going from bigger things to smaller things.

20. Inductive reasoning Opposite of deductive reasoning.
Uses specific observations to reach generalized conclusions and make broad statements.
Example:
Specific observations:
It is hot outside.
There are little to no shadows on the ground.
General conclusion
The sun must be directly above
Smaller to bigger…..

21. Faulty Reasoning Faulty reasoning leads to faulty conclusions.
Fully research and interpret data before reaching conclusions.
If the data is inaccurate or unsupported then the conclusions you draw from that data will also be false.
