 After and observation a question is generated.  A good question is specific and uses what and how.  Leads readers into the experiment  Example : How high would a rose plant grow if the amount of water varied?

 If….then…  NOT just an “educated guess”.  Very specific regarding details (amounts, units, time, number of trails…)  Eg) If 10mL of water is added to rose plant A and 20mL of water is added to rose plant B, then rose plant A will grow taller than rose plant B.  Can you identify the variables (IDV,DV)?

 Independent Variable (IDV): the variable that is changed/manipulated by the experimenter.  Dependent Variable (DV): the variable that changes as a result of what the experimenter changes (the variable that is measured)  Controls: constant variables – stay the same to ensure your experiment changes are due to the IDV.  Flower Example:  IDV:I am changing the amount of water  DV: I am measuring the height  Controls: same type of rose plant, type of water, time of day, amount of light ….

 Quantative: numerical data  Qualatative: Observational data  Organize all data in a chart by variables  Concise and neat

 LINE or Scatterplots in science (mostly) TITLE (should list both variables) IDV (units) DV (units) Key Label Axis and equal spacing

 Results SUPPORT or DO NOT SUPPORT your hypothesis and why – refer back to your data.  Discuss results/analyze the data – use the numbers and graph to support your interpretation  Discuss bias or errors – what could have happened that could explain your results, besides your fantastic lab.

 Scientific Law: accepted as true by all  Law of gravity  Scientific Theory: An idea that is supported by lots of data but not necessarily accepted by all as true.  Evolution
