6 NFPA CHEMICAL HAZARD LABEL Least Serious 4 Most Serious 40 Flammable vapor which burns readily Substance is stable

7 NFPA CHEMICAL HAZARD LABEL Avoid water. May detonate with heat or ignition. Severe health risk. Burns readily. Diborane

8 NFPA CHEMICAL HAZARD LABEL Complete Label for Phosphine

9 Write down What each symbol stands for

10 SDS Safety Data Sheet On file for all purchased chemicals. Includes all information shown on a chemical label and more. Different formats are used by different chemical companies.

11 SDS

12 Notebook Format Date Warm up questions and answers 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 - Pictures  You may write on the back  Start with a new page each day

13 Identify the problem Form a hypothesis Test hypothesis by performing experiments Analyze data Draw conclusions Chapter 1 Steps of the Scientific Method

14 The Experiment Independent 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 -Motion Theory: something that is likely to be true, but has not been proven Kinesio Tape

16 Homework Signed syllabus SpongeBob worksheet

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)

18 Hypothesis The length of your arm span is the same as your height Example 1:1 160cm/160cm = 1:1

19 Table 1. Data Collection SubjectIndex finger length Hand span (pinky to thumb) Forearm (Wrist to elbow) Arm length (shoulder to fingers Arms span HeightFoot length Self Partner #1 name Partner #2 name Partner #3 name

20 Table 2. Data Analysis SubjectRatio height to forearm Ratio height to arms span Ratio hand span to index finger Ratio arm length to index finger Ratio arms span to forearm Ratio of your hypothesis Self Partner # 1 name Partner # 2 name Partner # 3 name

21 Conclusions 1. What is the ratio of your height to your arms span? 2. Is your arm span the same as your height? How about your group members? 3. What is the ratio of your height to your forearm? 4. What is the ratio of your hand span to your index finger? 5. If the ratio is 1:1 what does it mean? 6. Compare yourself with your partners, does everyone have the same ratio? Who does and who doesn’t? 7. Does your data support your hypothesis?
