Problem (Problema)
•A questionquestion that compares variables.
•What you want to find out?
–Example: Does the drop height affect the bounce height of a superball?
pregunta compara las variables
¿qué quieres saber?
![Page 8: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/8.jpg)
What Are
• Something that changes.cambios
![Page 9: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/9.jpg)
Look back at the last example:
Example: Does the drop height affect the bounceheight of a superball?
What two things are changing?
Drop height, bounce height
These are the VARIABLES.

What is an Independent Variable?
(Also called Manipulated Variable)
We manipulate, or change it, on purpose. manipular o cambiar
variables independientes
![Page 11: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/11.jpg)
Example: Does the drop height affect the bounce height of a superball?
Independent Variable in example: Drop heights used (we change them on purpose)
![Page 12: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/12.jpg)
What is a Dependent Variable?
(Also called Responding Variable)
Changes depending on some other factorsVariable we are trying to find out (data you are collecting) cambios en función de otros factores
variables dependientes
![Page 13: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/13.jpg)
Example: Does the drop height affect the bounce height of a superball?
Dependent Variable in example: bounce heights (We don’t know them before we start.)
![Page 14: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/14.jpg)
What is a Constant?
Does not change for the duration of an experiment
Known as the controlled variable.
no cambia
constante
![Page 15: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/15.jpg)
Example: Does the drop height affect the bounce height of a superball?
One constant in example: superball (Does not change during the experiment - same ball would be used)
![Page 16: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/16.jpg)
Hypothesis
•EDUCATED GUESS
•What you think the results of the experiment will show
conjetura
¿Qué crees que los resultados del experimento se muestran?
![Page 17: Investigación Científica. A logical, problem- solving technique Scientific Inquiry Qué es? Una técnica lógico, la resolución de problemas](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649ce05503460f949aa91e/html5/thumbnails/17.jpg)
Example: If a superball is dropped from increasing heights then the bounce heights will also increase because…(explain why)

Materials
•List of items used to conduct an experiment (Don’t list pencil and paper unless part of experiment.)
•Be sure to list quantities and sizes of equipment (metric)

Procedure
•Numbered steps of the experiment that will be followed to answer the problem
Note: An experiment can only test one independent variable at a time.
Note: To ensure reliability and validity, repeated trials should be done.

Why Do We Use Graphs?
•Graphs help us visualize numerical data.
•There are several different types of graphs:–Bar graphs –Pie graphs (Circle graphs)–Line graphs
gráficos nos ayudan a visualizar datos numéricos

Pie Graphs
Pie graphs are used to compare the parts of a whole.

Line Graphs
Line graphs are used to the show the relationship between variables. Many times line graphs show change over time.

Graphing Variables
• The Independent Variable (Manipulated Variable) is graphed on the X-Axis
• The Dependent Variable (Responding Variable) is graphed on the Y-Axis
