Scientific Steps TOPIC: MY GOAL DID YOU KNOW? Fri 8.26.10 Scientific Steps I will begin learning the FOUNDATION vocabulary for Standard 1, The Nature of Science Cow’s milk contains amounts of pus and blood cells. If you’re lucky, you might get some traces of antibiotics, too!

Procedure for the Day…. AKA “What are we doin’ today?” Review LLCCC of Scientific Process article Learn Key Terms! Reach IWL Goal Did you reach the goal for the day? IWL GOAL Key Terms Term Definition

Stop Think And Review Code LLCCC Strategy: Locate Label Cover Check ISN page 7-8 “Methods in Biology” LLCCC Strategy: Locate Label Code Cover Check

Stop Think And Review Locate, Label, Code, Cover, Check Sci.Meth. ans. ques. Explain. For ques. Must be testable! Test of hypoth Control = no treatment Exp. = treatment IndVar = Test Var. DepVar = Outcome Var. Info gathered – reliable when repeating exp. Eval. – used to repeat exp. Hypoth. supported by many exp. LLCCC= L2C3 Locate, Label, Code, Cover, Check The Methods of Biology .

Quant = #’s Qual. – words Right vs Wrong Bias = favoritism Coding the paragraph WILL help GET BETTER at summarizing what is important… which will reduce the amount of work you will need to do!!

Stop Think And Review 2. Steps to the Scientific Process: Conclusion Observation Hypothesis Experiment Data collection Conclusion

YOUR JOB TODAY Complete the Key Term list on page 6 of your ISN This list is a “Ticket to Test”… Use your textbook – Chapter 1 You may NOT use the glossary!! The glossary will NOT help you UNDERSTAND the term! You MUST learn to APPLY the term to certain situations, not just memorize…. The TEXT that SUPPORTS the term will help you UNDERSTAND! Writing the shortest answer possible will NOT earn you a Ticket to Test! USE YOUR TIME WISELY! We will review at end.

Standard 1 Key Terms Definition Term Page 6 in ISN 1. Observation vs Inference Obtaining info by using senses ----vs---- conclusion based on previous knowledge 2. Hypothesis Proposed explanation to solve a problem 3. Experiment Test of a hypothesis A) Control Group Group that does not change B) Experimental Gr. Group that is tested – something is changed in it C) Independent Var. TEST VARIABLE = CAUSE - The manipulated variable -= the one that I, the scientist, change D) Dependent Variable OUTCOME VARIABLE = EFFECT – what happens as a result of the change

Stop Think And Reflect Did we reach our goal? to begin to re-learn the FOUNDATION terms to understand the Scientific Process… Did you reach that goal? How do you know you reached the goal? What are YOU going to do if you did not reach that goal?? 10

Check to see if you really did reach the goal for the day! .The first step in the scientific process is to make an -------------. A hypothesis MUST be a -------------one. Scientist usually perform controlled experiments which means the experiment has a ---------- group and an ------------------ group. The ------------- group is the one that stays the same AND is used for COMPARISONS! The ------------------- group is the one you are making CHANGES to; the one you are experimenting with. The -------- variable is the thing you’re testing – the CAUSE of the change The --------------- variable is the result/outcome – the EFFECT of the change. observation testable control experimental control experimental test outcome

HOMEWORK Now is the time to begin LEARNING these terms!!!! Be the change you wish to see in the world 12 12
