Good Morning! In your notebook, create a page for “Scientific Method” NOTES. Write and answer the following: What VARIABLES had to be considered when engineering the Lunar Rover? Come up with at least 3 different variables. How can a VARIABLE change the outcome of an experiment?

The Scientific Method AC2E Science Mr. Magner

How Do We Use Science Every Day?

We must collect information, or DATA in any way possible We must collect information, or DATA in any way possible. What are our five senses? Are there more? What tools do we need?

Science? Engineering? Problem Solving.

“Facts are not science - as the dictionary is not literature” Write this down. What does it mean?

The Scientific Method Scientific problem Hypothesis Test Observe Conclude Theory

The Control Control– Control variable is the one element that is not changed throughout an experiment. because its unchanging state This allows the student to study the relationship between the other variables, to compare results, and to help refine experiments.

Scientific Problem Create an observation using the senses of sight, touch, taste, or hearing to gather information about a problem that can be tested.

The Aral Sea was once an important fishery and tourism spot. (Click for Video). What led to the decline of the sea?

Hypothesis A tentative explanation for a phenomenon, used as a basis for further investigation

Experimentation Procedure that is carried out according to specific guidelines and is repeatable. Independent Variables are factors that can be changed Dependent Variables cannot

Independent v. Dependent Variables - It is a c - Someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. 

Independent v. Dependent Variables Depends on other factors. - A test score could be a dependent variable: It could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does

Types of Variables Independent Variable - Someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. 

Dependent Variables Dependent Variable -A dependent variable is affected by another, typically the independent variable in the equation. The output or outcome of variation is being affected.

The Control Control– Control variable is the one element that is not changed throughout an experiment. because its unchanging state This allows the student to study the relationship between the other variables, to compare results, and to help refine experiments.

Observations Report and record precise and accurate data. At this step you are simply stating what happened, NOT WHY.

Conclusion A statement about the validity the hypothesis, supported with data from the tests that were conducted. Good conclusions state whether or not the hypothesis was valid. What observed data, measurements, or experimental proof supports your conclusion?

THEORY Formulate the simplest general rule that organizes the three main ingredients – hypothesis, prediction, experimental outcome – into a theory.

Prediction You must produce 1 page of notes. Cornell Notes need to include a summary and 4 review questions. Prediction
