Scientific Inquiry: Developing & Conducting Investigations
Transcript of Scientific Inquiry: Developing & Conducting Investigations
I will collect data from this variable.
It is like the effect in cause and effect.
To find the IV, I can ask, "What am I measuring or looking for?"
Dependent Variable (D.V.)
Developing & Conducting Investigations
A procedure or steps that scientists use to solve a problem or answer a question
All experiments start with a question or problem
Does the (independent variable) affect the (dependent variable)?
Question or Problem
TSW develop and conduct a grade level appropriate investigation with assistance.
I can make changes to this variable.
This is the only thing that should be changed in an experiment.
It is like the cause in cause and effect.
To find the IV, I can ask, "What am I changing?"
Independent Variable (I.V.)
An educated guess, or prediction
Should be written as an “If, Then, Because” statement.
If the _________ is __________ ,
(independent variable) (Increased/decreased)
then the ________ will __________
(dependent variable) (increase/decrease)
Research done to assist in an experiment
keeps the experiment safe - understand materials
makes your experiment connect better to real life
helps you predict results
I will keep the experiment fair with this variable.
It will not change from trial to trial.
To find the Control Variables, I can ask, “What do I need to make each trial and test exactly the same?"
Control Variable (C.V.)
uses evidence from the experiment to prove/disprove the hypothesis
analyzes what happens in an experiment
What could you do if you had an "I wonder..." question?
triple beam balance
OBSERVATIONS: N vs. L
