  1. Inquiry (PS-1) Unit 1

  2. Tuesday 8/17 AGENDA: • Question Ball Procedures • Syllabus • Emergency Evac Plan • Find Some one who….

  3. Panther Drill 1 Get out your procedures list from yesterday and look it over for about 2-3 minutes and be ready to answer questions about what to do when.

  4. Syllabus and Standards Fire or evacuation: Proceed in an orderly quiet fashion to our area, and stay in a group so I can call roll

  5. Notebook Each Page will have a page number and a date, I will tell you what number it will be as we do notes and assignments. Notebooks will be collected at the end of the units and be graded for completeness, organization, and correct answers to assignments. Your procedures list goes in the front of your notebook, followed by your syllabus and standards.

  6. EMERGENCY

  7. Fire or evacuation: Proceed in an orderly quiet fashion to our area, and stay in a group so I can call roll Lockdown: Move to the corner of the room from the promethean board around to the cabinet. Lights go off, doors stay looked, everyone will stay calm and QUIET.

  8. Tornado: move away from the window, kneel down, face the wall and cover your head. Earthquake: Take cover under your desk or a table stay if you are near windows, move to the center of the room and take cover

  9. TO DO TONIGHT • Do syllabus quiz and get it signed • Make observations about what is around you

  10. Wednesday 8/18 Stand: PS-1.1,4 AGENDA: • Panther Drill 2 (What is Science) • Pre-assessment Unit 1 • Notes / Discussion Observations • Given observation make a hypothesis.

  11. Panther Drill # 2 In the Warm up section of your notebook, put today’s date, “Panther Drill #1” and answer the following in your own words and thoughts What is Science and why do we study it.

  12. The study of the living world around us Why Study Science? We study science to explain the world around. When we encounter something that is not known we must study the situation to understand the world around us. How do we Study the unknown…….. It all starts with: OBSERVATIONS

  13. Pre-Test Quietly complete the pre test and turn it in the in-box. While others are still working, list some of the observations that you made about the world around you last night. Leave a blank line between each observation. This list will be page 1 of UNIT 1 in your notebook. Make the top line of your page look like this: Unit 1 8/18/10 page 1

  14. Thursday 8/19 Stand: PS-1.1 AGENDA: • Panther Drill 3 (Hypothesis) • Notes / Discussion On Sci. Method and Exp Design • CW/Activity Sci. Method

  15. Panther Drill 4 8/20 • Define the term hypothesis in your own words. Write a hypothesis for the following observations • My plants seem to grow larger in the sunny part of my garden • My grades seem to be better when I study w/ my I-pod on.

  16. Experimental Design How do we design experiments • Initial Observation • Information Gathering • books, magazines, internet, or professionals in the field • State the purpose of your Project • Write a statement describing what you want to do or show • Identify Variables • List of things that can effect the outcome of your • experiment.

  17. Other info to know: 1-Parts of and Experiment: a) Control set-up: Part of experiment that has a known result or expected result. b) Variable/ Experimental: Part of the experiment that does not have and know or expected results. What changes in the experiment.

  18. Independent Variable: is a single factor that the experimenter changes during the experiment. Dependent Variable: a factor or condition of the group examined that changes because of changes in the independent variable. ** ALL OTHER FACTORS MUST REMAIN CONSTANT!!!!!

  19. In a well constructed experiment there is usually a cause and effect relationship or connection between the dependent and the independent variable. ** If one changes then the other the other will change if they are connected. IE Cause and effect relationship: If I turn on down the temperature on the thermostat, then the room will get cooler. “If one changes then the other will”.

  20. Variable Relationships A direct variation (or proportion) is one in which, one variable increases as the other increases or as one variable decreases the other decreases. A straight line with a positive slope indicates a direct relationship An inverse variation(or proportion) is one in which the product of two quantities is a constant. Frequency and wavelength are inversely proportional. As one quantity increases the other quantity decreases.

  21. State your hypothesis. Use your list of variables and choose one at a time to Manipulate (change) If you choose more than one at a time, you will not know which one caused your observed condition Translate your variables into a hypothesis. “If variable X increases, then variable Y will…?…”

  22. 6. Design your Experiment (cont.) - Guidelines for Experimental Procedures: a. Select only 1 thing to change (variable) in each experiment b. Change something that will help you answer your question c. The procedure must tell you how you will change one thing d. The procedure must tell you how you will measure the amount of change e. Each experiment should have a control

  23. 7. Obtain Your Materials - Make a list of things you will need to perform your experiment and prepare them 8. Perform the Experiment Record EVERYTHING you do and EVERY result you get. This is your Raw Data. REPEAT REPEATREPEAT • Keep careful notes on everything you do and see happening. Observations are valuable when drawing conclusions and locating experimental errors 9. Summarize your Results Any calculations required, construct graphs or data tables.

  24. 10. Draw your Conclusion Use your results to try to answer your original questions Is your hypothesis correct? Why or Why not? What difficulties did you encounter? What unexpected things did you observe? What would you do differently next time? 11. Look for Errors Random Errors: non-reproducible, possibly the result of something you did differently each trial. Systematic Errors: Something wrong w/ your design or equipment. IE your meter stick is missing the 1st cm or you balance is not calibrated correctly

  25. 12 REPORT: Turn in work or publish findings

  26. Scientific Method, Controls and Variables
