Transcript of Scientific Process

Scientific Process


What is science?
What is a scientist?
A person who...
asks questions
discovers
measures
wonders
records
experiments
imagines
invents
classifies
observes
records
tries
....as a way to gain new knowledge!


Science is....
The word science comes from the Latin "scientia," meaning knowledge

Science is the process of:
wondering
observing
discovering
inventing
designing
recording
experimenting

What is science?
What is a scientist?
What do scientists do?
Draw a picture of a scientist at work
Did you draw something like this?
Scientific Method
Observation and Inference
Observation
: act of using one or more of your senses to gather information (Smell, touch, taste, see, hear)

Inference
: logical explanation of an observation that is drawn from prior knowledge or experience
Hypothesis
Asking Questions
Variable
A possible explanation for an observation that can be tested by scientific investigations. Written If…then…because

any item, factor, or condition that can be controlled or changed

Procedure
a numbered, step-by-step set of directions
written to...
explain how to conduct an investigation
identify what data will be collected
needs to be detailed & easy to follow
Data
Conclusion and Results
Is a summary of your experiment- Explain what you observed, learned, concluded
Must include:
Topic sentence restating purpose of lab
Rewrite your hypothesis & explain if it was right or wrong
Summarize results/data
Explain what the data means
Explain if there were any issues or problems
Concluding statement that summarizes the lab findings
Independent
Dependent
Control
What is being tested
Scientist Changes

Result
What we look for a change in

Factors kept the same

Scientific Process
LT: Explain the basic steps of the scientific process
is a process for experimentation that is used to explore observations and answer questions.
21
Asking Questions
LT: Create scientific questions
BW:
1. Explain the scientific process in your own words
2. Do scientists always follow the scientific process?
3. Give an example of where you used the scientific process in your daily lif
e

Notes:
22
Observation and Inference
LT: Make observations and create inferences
BW:
1. What is a scientific question?
2. What makes a good scientific question?
Notes:
Observation:


Inference:

Examples to review as a class
Observation
Question
Hypothesis
If-
Independent Variable
(Scientist Changes)
Then-
Dependent Variable
(Changes as a result)
Because-
explanation based on inference
1.The higher the temperature of the air in the oven, the faster a cake will bake.

2.Lemon trees receiving the most water produced the most lemons.

3.An investigation found that more potatoes were produced when the soil was fertilized than when it wasn't.

4.Students measured the temperature of the water at different depths in Lake centennial and found that the temperature varied.

5.The more lead in gasoline the more pollution produced

1st step in the scientific process!
usually about something that you observe or wonder about
Start with words like How, What, When, Who, Which, Why, or Where?
Asking questions
Theory questions (require extensive knowledge)
Verification question (basic data collecting)
Experimental questions (testable)
3 types of science questions
build on prior knowledge
are testable
are focused
leads to other good questions

Good Science Questions
23
Variables and Hypothesis
8/23
LT: Identify variables and create a hypothesis.
BW:
1. Explain the first step of the scientific process.
2. What is the difference between observations and inferences?
A set of values, facts, or information used to calculate, analyze, or plan something
can be qualitative (words) or quantitative (numbers)
can be represented using a model
dependent variable on the y-axis and the independent variable on the x-axis
24
Procedures
8/26
LT: Correctly write and follow a procedure
BW: circle the independent, square the dependent
1. Write a hypothesis for the following question:
Will students score better in school if they believe their minds can grow?
2. Think of something you are interested in... write an experimental question and a hypothesis for it
25
Data
8/29
LT: Follow a procedure to accurately collect & represent data
BW:
1. Why is writing a specific procedure important?
2. Why is following a procedure important?

Notes:
Paper Airplane Lab
Discovery ed video
1 airplane per group
Step 1. Throw airplane, count in cm how far it traveled 1m=100cm
Step 2. repeat 4 times, then calculate average
Step 3. Add tape to nose, repeate steps 1 and 2
Step 4. Answer questions on the back

Conclusion
9/1
LT: Write a lab conclusion
