12 Notebook Format You may write on the back Start with a new page each DateWarm up questions and answers1.2.3.Minimum 3 sentences summarizing main ideas from today’s notes and explain what they are- Main ideas- Questions related to the notes- Notes from lecture- Explanations- Diagrams- PicturesYou may writeon the backStart with anew page eachday
13 Chapter 1 Steps of the Scientific Method Identify the problemForm a hypothesisTest hypothesis by performing experimentsAnalyze dataDraw conclusions
14 The ExperimentIndependent variable: the item being tested in the experiment (What YOU change)Dependent variable: the item being measured in an experiment (DEPENDS on the independent variable)Control group: The part of the experiment that is left unchanged. (The normal group)
15 After the experiment…. Law: something that has been proven to be true -Gravity-MotionTheory: something that is likely to be true, but has not been provenKinesio TapeWork on Spongebob scientific method worksheet with a partner in class
17 Scientific Method Investigation Are there specific ratios that exist between the lengths of certain parts of the body and other parts?Create a hypothesis (a statement that answer the question above and can be tested)Make a hypothesis
18 Hypothesis The length of your arm span is the same as your height Example 1:1160cm/160cm = 1:1
19 Table 1. Data Collection Subject Index finger length Hand span (pinky to thumb)Forearm (Wrist to elbow)Arm length (shoulder to fingersArms spanHeightFoot lengthSelfPartner #1 namePartner #2 namePartner #3 name
20 Table 2. Data Analysis Subject Ratio height to forearm Ratio height to arms spanRatio hand span to index fingerRatio arm length to index fingerRatio arms span to forearmRatio of your hypothesisSelfPartner# 1 name# 2 name# 3 name
21 Conclusions What is the ratio of your height to your arms span? Is your arm span the same as your height? How about your group members?What is the ratio of your height to your forearm?What is the ratio of your hand span to your index finger?If the ratio is 1:1 what does it mean?Compare yourself with your partners, does everyone have the same ratio? Who does and who doesn’t?Does your data support your hypothesis?
