Scientific Method
What is the independent variable?
The independent variable is the variable that is intentionally changed. (The Cause)
Jackson State and Southern University have an influence on Karr's culture.
What is the independent variable?
Jackson State and Southern University's influence on Karr's culture.
The scientists can change one variable
independent variable
A way of thinking that favors one outcome or interpretation
Identifying problems, planning experiments, recording observation and correctly reporting data are some of the most inportant
Science Skills
Name all of the variables in the experimental design.
Independent variable
dependent variable
control group
experimental group
How much can my hair grow if I pour rice water in my hair everyday?
Is this an hypothesis based off what we learned in Ms.Juluke's class?
No this is an Observation
A descriptive statement or equation that reliably predicts events under certain is called
Law
the ability and willingness to assess claims critically and to make judgements on the basis of objective and supported reasons
critical thinking
A measure of gravitational force exerted on an object is
Weight
Name all of the steps in the scientific method
Observation/Question
Hypothesis
Experimental design
Results and analyze
Conclusion
If I water my plants everyday then they will grow really tall.
Is this a hypothesis?
Yes
The variable that changes as a result
Dependent variable
A Representation of an object or event that can be studied to understand the real object
scientific model
The most important skill is learning to think creatively
critically
I failed all of my test in Ms.Juluke's class.
What is the observation/ problem?
What is a hypothesis?
I failed all of my test.
If I studied more then I would pass my test in Ms.Juluke's class.
The air in Ms. Juluke's class is broken.
What is the observation?
What is the hypothesis ?
It's really hot in Ms.Juluke's class.
If Karr fixes Ms.Juluke's air then it won't be hot in her class anymore.
A series f steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis and stating the conclusion
Scientific Method
An interpretation based on observation and prior knowledge is called
Inference
a description of how close a measurement is to the true value of the quantity measured is called
Accuracy
Ms.Juluke has locs down her back and last night she counted them. In total she has 117 locs.
What example of data is this?
Quantitative Data and Qualitative data.
Ms.Juluke wanted to test the porosity of her hair so she cut off some of her hair and placed it in water, juice and coke.
Is Ms. Juluke's experiment valid?
Why or why not?
No because she changed too many factors.
She can make it valid by placing the different strands of hair in just water.
A system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation is
Theory
The facts, figures and other evidence collected in an experiment
Data
Exactness, of measurements can vary
Precision
