1. Unit 1: The Scientific Method El Método Científico

2. The goal of science is to investigate and understand the natural world, to explain events in the natural world and to make useful predictions.

3. What are the steps?! ¿Cuáles son los pasos?
The Scientific Method - El Método Científico
State the problem - Indique el problema
Ask a question - Haz una pregunta
Form a hypothesis - Formar una hipótesis
Design an experiment - Diseñar un experimento
Collect data/results - Recoger datos / resultados
Draw a conclusion - conclusión

4. What’s a hypothesis?! ¿Qué es una hipótesis?!
Hypothesis - A prediction, an educated guess, a possible answer to the question.
Predicción, conjetura, respuesta posible.

5. Variables
Dependent (dependiente) variable – variable that responds to the independent one. AKA responding variable.
Variable que responde a la independiente
Independent (independiente) variable – variable that is controlled. AKA manipulated variable.
variable que usted tiene control

6. Experimental Variables
Dependent variable is the factor in an experiment that a scientist wants to observe, which may change because of the manipulated variable; also known as a responding variable.
Independent variable is the factor in an experiment that a scientist purposely changes.
Control variable(s) is the factor or factors in an experiment that the scientist purposely keeps the same between groups.

7. Inference a conclusion reached on the basis of evidence and reasoning.
the process of inferring something.

9. Controlled Experiment
There are at least 2 groups, one of which does not receive the experimental treatment.
Allows a scientist to test a single variable at a time.

10. Hypothesis vs. Theory Hipótesis vs. Teoría
Hypothesis is an educated guess.
Hipótesis es una conjectura.
A theory is an idea well supported with evidence.
La teoría es una hipótesis bien apoyado. Tiene pruebas.
Like the theory of plate tectonics.
Al igual que la teoría de la tectónica de placas.
We know it to be true because of all the supporting evidence.
Sabemos que es verdad, porque de todos las pruebas de apoyo.

11. Theory vs. Law Teoría vs Ley
A theory is well supported with evidence.
La teoría es una hipótesis bien apoyado. Tiene pruebas.
A law is constant. Under the right conditions it will have the same results every time.
Una ley es constante, no importa qué. En determinadas condiciones, tendrá los mismos resultados cada vez.
For example the law of motion – for every force there is equal and opposite force.
Por ejemplo, la ley del movimiento - por cada fuerza existe fuerza igual y opuesta.

12. Scientific Principles los principios científicos
Principles explain the ‘why’ and ‘how’ of certain phenomena.
Principios explicar el "por qué" y "cómo" de ciertos fenómenos.
For example – static electricity
Por ejemplo - la electricidad estática
