  1. If you did not pick up homework yesterday do so today!! Due FRIDAY Get out ISN we are taking notes over Scientific Method/Lab Write up Tutorials tomorrow morning for lab make-up and homework help 8am

  2. Scientific Method/Lab Write up An orderly and systematic way of solving a problem

  3. 1. PROBLEM • QUESTION YOU ARE SEEKING AN ANSWER FOR

  4. ALWAYS IN THE FORM OF A QUESTION. • Does the amount of liquid affect the growth of plants? • Does the type of liquid affect the growth of plants? • Does the amount of light affect the growth of plants? • Does the type of soil affect the growth of plants? MUST BE ABLE TO ANSWER THROUGH EXPERIMENTATION

  5. -RESEARCH • COLLECT KNOWN INFORMATION • EXAMPLE: RESEARCH READ OBSERVE

  6. -PREDICTION • A LOGICAL GUESS OF AN OUTCOME BASED ON DATA AND PRIOR KNOWLEDGE. IF YOU HEAR THUNDER, YOU COULD PREDICT THAT IT WILL RAIN.

  7. 2. HYPOTHESIS • EDUCATED GUESS TO ANSWER THE QUESTION • The more research, the better our hypothesis

  8. Should be written in an “if- then” statement • I think if the amount of light is changed, then the plant growth will be affected. • I think if the type of liquid is varied, then the plant growth will change. • I think the type of fertilizer affects plant growth.

  9. Face Book Activity

  10. 3. EXPERIMENT • PLANNED WAY OF SOLVING A PROBLEM • WRITTEN AS STEPS • KNOWN AS PROCEDURE.

  11. GIVING INSTRUCTIONS LAB Tell me how to make Peanut butter and Jelly Sandwich

  12. GIVING INSTRUCTIONS Quick Write- Using 5 complete sentences, describe what happened and write what you learned

  13. VARIABLE • FACTORS IN AN EXPERIMENT THAT CHANGE

  14. 1. Independent Variable • M- Manipulated • I- Independent • X- X axis • This is the variable that you are purposefully changing. • YOU MAY ONLY HAVE 1 INDEPENDENT VARIABLE

  15. 2. Dependent Variable • D- Dependent • R- Responding • Y- Y axis • This is the variable you are measuring it will be recorded in your data!

  16. CONSTANT • FACTORS IN AN EXPERIMENT THAT A SCIENTIST PURPOSELY KEEPS THE SAME.

  17. CONTROL group that serves as the standard of comparison. Treated as the same as the samples, but not exposed to the independent variable

  18. Peanut Butter Jelly Time! Write the procedure to make a peanut butter jelly sandwich. Be sure to write them in steps and be specific!

  19. 4. DATA/ OBSERVATIONS • COMPILE DATA • INFORMATION COLLECTED FROM EXPERIMENTS

  20. -OBSERVATION • DATA THAT YOU COLLECT THAT YOU CAN PHYSICALLY OBTAIN USING YOUR 5 SENSES.

  21. -INFERENCE • LOGICAL INTERPRETATION BASED ON PRIOR KNOWLEDGE AND EXPERIENCE. IF SOMEONE IS WET, YOU COULD INFER IT IS RAINING OUTSIDE.

  22. Observations vs. Inferences • The plant has roots. • The plant uses water. • The plant has leaves. • The plant has flowers. • The plant grew from a seed. • The plant is growing in soil. • The plant is green and yellow. • The plant is growing in a pot.

  23. Young people are playing basketball. • The players are in high school. • People are watching the game. • The score is tied. • The game is almost over. • The people are indoors. • There are 6 players

  24. MYSTERY Diapers • List 5 observations • (I see, I feel, I smell, etc) • List 5 inferences

  25. PRECISION • MEASURING WITH ACCURACY AND EXACTNESS. A MEASUREMENT OF 5.5CM IS MORE PRECISE THAN 5CM.

  26. AVERAGING NUMBERS • MANY TIMES SCIENTISTS WILL HAVE SEVERAL ANSWERS FOR A PART OF AN EXPERIMENT. The best method of dealing with this situation, is to average.

  27. EXAMPLE OF AVERAGING • ADD THE DIFFERENT ANSWERS TO REACH A TOTAL. THEN DIVIDE THE TOTAL BY THE NUMBER OF DIFFERENT ANSWERS.

  28. GRAPH • A PICTURE OF DATA- NUMERICAL DATA

  29. KINDS OF GRAPHS • 1. CIRCLE GRAPH A. DIVIDED CIRCLE B. SHOWS HOW A PART OF SOMETHING RELATES TO THE WHOLE VALUE.

  30. HELPS YOU COMPARE THINGS SUCH AS – AMOUNTS or QUANTITIES BAR GRAPH

  31. LINE GRAPH • A. LETS YOU PLOT SEVERAL DIFFERENT FORMS OF DATA. • B. HELPS YOU SEE PATTERNS OR TRENDS.

  32. TAILS Title: Includes both variables Axis: IV on X-axis and DV on Y-axis Interval: The interval (4) is appropriate for this scale. Label: Both axes are labeled. Scale: Min and max values are appropriate.

  33. GRAPHING DEDUCTIONS Title (5) X & Y title (5) X label/ scale (5) Y Label/ scale (5) Start at zero (5) Straight lines (5) # increments (5) IV/ DV (20) Plot (20)

  34. 5. CONCLUSION • ANSWER TO THE PROBLEM

  35. THEORY • MOST LOGICAL EXPLANATION FOR EVENTS THAT HAPPENED

  36. LAW • A THEORY THAT HAS BEEN TESTED MANY TIMES AND IS GENERALLY ACCEPTED AS TRUE.

  37. REPLAY Conclusions • R – restate the problem question • E – explain what you did to test • P – pull in the data • L – look for patterns • A – answer the problem question • Y – yes or no to hypothesis (hypothesis correct? Why or why not?)
