Unit 1: The Scientific Method El Método Científico http://www.youtube.com/watch?v=_ 7sSuhQ1_24

What are the steps?! ¿Cuáles son los pasos? The Scientific Method - El Método Científico 1.State the problem - Indique el problema 2.Ask a question - Haz una pregunta 3.Form a hypothesis - Formar una hipótesis 4.Design an experiment - Diseñar un experimento 5.Collect data/results - Recoger datos / resultados 6.Draw a conclusion - conclusión

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

What’s a hypothesis?! ¿Qué es una hipótesis?! Make a hypothesis for this question. Haz una hipótesis para esta pregunta. – Can a whale hear, how do you know? – ¿Puede oír una ballena? Si es así, ¿cómo lo sabes? – http://wvia.pbslearningmedia.org/resource/tdc02.sci.life.colt.ologist/guess-how-whales-hear/ http://wvia.pbslearningmedia.org/resource/tdc02.sci.life.colt.ologist/guess-how-whales-hear/ – Was your hypothesis accepted or rejected?

Variables Dependent (dependiente) variable – variable that responds to the independent one. – Variable que responde a la independiente Independent (independiente) variable – variable that you control. – variable que usted tiene control What are the dependent and independent variables in the whale hypothesis? ¿Cuáles son las variables dependientes e independientes en la hipótesis?

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 group is the factor or factors in an experiment that the scientist purposely keeps the same.

Collecting Data Two types of data. 1.Quantitative: numerical data, a number (Quantity) 2. Qualitative: written observations, words (Quality)

Drawing a Conclusion The Last Step Inference: A logical interpretation based on your prior knowledge. (to infer)

Work with your neighbor! You may work on your own if you prefer. – Complete the hypothesis worksheet, using your notes. Complete la hoja de hipótesis. – Keep it in your BINDER ! Guárdelo en su carpeta! A few more notes!

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. – http://wvia.pbslearningmedia.org/resource/ess05.sci.ess.earthsys.plateintro/plate-tectonics-an-introduction/ http://wvia.pbslearningmedia.org/resource/ess05.sci.ess.earthsys.plateintro/plate-tectonics-an-introduction/ – We know it to be true because of all the supporting evidence. Sabemos que es verdad, porque de todos las pruebas de apoyo.

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. – http://wvia.pbslearningmedia.org/resource/phy03.sci.phys.mfw.asrnt/newtons-third-law-of-motion-astronauts-in-outer-space/ http://wvia.pbslearningmedia.org/resource/phy03.sci.phys.mfw.asrnt/newtons-third-law-of-motion-astronauts-in-outer-space/

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 – http://wvia.pbslearningmedia.org/resource/phy03.sci.phys.mfe.zsnap/static-electricity-snap-crackle-jump/ http://wvia.pbslearningmedia.org/resource/phy03.sci.phys.mfe.zsnap/static-electricity-snap-crackle-jump/
