Practicing Good Science Physics August 31(A)/September 1(B)
Objectives • identify parts of the scientific method • evaluate why scientist use the scientific method and the international system of units
Some of the Rules Topic International system of units • Facts • SI units • Allow for a universal measurement system
More about SI units Topic How to convert between units? What is bigger or smaller? • Facts • Base = no prefix • Kilo = 1000 bigger than base Centi= 1/100 smaller than base • Milli- 1/1000 smaller than base
Let’s Practice Convert the following 500 g = _____ 5 km = _____m 100 cm = _____ m Fill in the blank with greater than, less than, or equal to. 25 m ____ 2.5 km 1000 kg _____ 1 g 1 mm _____ 1 cm _____m _____ km
Some of the Rules Topic Scientific method • Facts • Ask questions • Make a prediction- hypothesis • Experiment • Collect data • State conclusion based on results • Apply, publish, and share work
Some of the Rules Topic How do we record our work as we explore the scientific method? Facts Title Experimental Question/Problem Hypothesis Materials Procedure (with lab safety, dependent and independent variables) Data Analysis Conclusion Discussion
Let’s Apply these ideas Complete at least one of the lab exercises, and record the information in your lab notebook. This will be a model for how to complete future lab exercises.
Closing • What is the value of the scientific method? • Why make a hypothesis? Why should one consider the independent, dependent and control variables? • How did everyone’s results compare? • What would you have to do in order for the conclusion to be accepted by the larger science community?
Homework • Review the lab safety contract and basic measurement for a quiz next class. You must pass the quiz with an 80% or higher before participating in the next lab • Due Sep 7- Part I Read the article and post a response to the blog on the website • Due Sep 9- Part II Respond to one post
