Monday Sep 20, 2010 Update Planners. Set up Cornell Notes. Books open to page 6. Today: What is Scientific Inquiry (aka Scientific Methods). Notebook check this week (Digging Deeper, Today’s Notes)

Lifesaver Lab #1 Ask Yourself These Questions Why did we get data that was different for so many students? Did we do something (or many things) incorrectly? Did we do ANYTHING correctly? What could we do differently next time?

Thinking Like A Scientist Page 6-7 Science - is a way of learning about the natural world and the knowledge gained in that process. Certain Skills are needed by Scientists Observing (senses) Inferring (explain or interpret observations) Predicting (forecast based on evidence) Scientific Attitudes (curiosity, open-mindedness, skepticism, creativity)

Scientific Inquiry (Method) Pages 8-11 Scientific Inquiry - is the way in which scientists study the world and propose explanations based on evidence. Scientific Inquiry Methods are Posing Questions Developing a hypothesis Designing Experiments Collecting Data Interpreting Data Drawing Conclusions Communicating Data

Scientific Inquiry (Method) Questions - Come from observations, inferences or curiosity. Hypothesis - an explanation for a set of observations or an answer to a scientific question that can be TESTED! Prediction that can be tested.

Scientific Inquiry (Method) Page 9 Designing Experiments MUST be a CONTROLLED EXPERIMENT. Experiment MUST test only one VARIABLE. Variable - The changeable factor in an experiment. There are 2 parts of a variable….

Scientific Inquiry (Method) 2 parts of the variable P Manipulated Variable (M.V.) - The thing that the scientist changes in the experiment. Aka Independent Variable Ex). Hot/Cold Water (Water Temperature is the M.V. 2. Responding Variable (R.V.) Aka Dependent Variable The thing that changes BECAUSE of the M.V. Ex.) the rate of dissolving of the Lifesaver

Scientific Inquiry (Method) Page Collecting Data - Data are the facts, figures and evidence from observations. Interpreting Data - Using graphs and charts help explain data.

Scientific Inquiry (Method) Page Drawing Conclusion - is a decision about how to interpret your data. (say what the data means). Hypothesis supported or not? Communicating Data - the sharing of ideas through written and spoken words.

Theories and Laws Page 12 Scientific Theory - a scientific explanation supported by repeated tests. Evolution Plate Tectonics Scientific Law - An observed pattern in nature. Gravity Law of Superposition
