  1. DINOSAUR TRACKS:A SCIENTIFIC INQUIRY PROJECT DINOSAUR TRACKS – GLEN ROSE, TX

  2. DINOSAUR TRACKS:A SCIENTIFIC INQUIRY PROJECT • PROJECT BACKGROUND: • HEAVY RAINS BEHIND DECKER MIDDLE SCHOOL UNCOVER A SEDIMENTARY ROCK SHELF DATING FROM THE CRETACEOUS PERIOD. DINOSAUR TRACKS

  3. DINOSAUR TRACKS:A SCIENTIFIC INQUIRY PROJECT • DMS 7TH GRADERS USE INQUIRY METHODS AND SCIENCE PROCESS SKILLS TO IDENTIFY THE DINOSAUR TRACKS AND DETERMINE THE CHARACTERISTICS OF THE ANIMALS THAT MADE THEM.

  4. WHAT IS INQUIRY? • INQUIRY IS INVESTIGATING QUESTIONS ABOUT THE WORLD USING SCIENTIFIC TOOLS AND STEPS. • HELPS AVOID ERRORS AND VERIFY DISCOVERIES. COMMON STEPS (BADLY DRAWN)

  5. SCIENTIFIC INQUIRY • 3 TYPES: • DESCRIPTIVE • COMPARATIVE • EXPERIMENTAL • USES THE SCIENTIFIC METHOD.

  6. LET’S MAKE A FLOW CHART… • DRAW AND LABEL THIS FLOW CHART IN YOUR INTERACTIVE NOTEBOOK.

  7. DESCRIPTIVE INVESTIGATIONS • DESCRIPTIVE INVESTIGATIONS LOOK AT BASIC INFORMATION ABOUT ONE THING. • ARE LESS FORMAL, DO NOT USE THE SCIENTIFIC METHOD. A DESCRIPTIVE INVESTIGATION: WHAT IS THE TRACK LENGTH IN METERS OF TRACK rp?

  8. COMPARATIVE INVESTIGATIONS A B • COMPARATIVE INVESTIGATIONS GATHER DATA TO COMPARE DIFFERENT THINGS. • LIKE DESCRIPTIVE, COMPARATIVE DO NOT USE THE COMPLETE SCIENTIFIC METHOD. WHICH DINOSAUR IS FASTEST?

  9. EXPERIMENTAL INVESTIGATIONS CHANGE ONE THING TO SEE HOW THAT THING AFFECTS AN OUTCOME – USING THE SCIENTIFIC METHOD. EXPERIMENTAL INVESTIGATIONS IF…WOULD WE SURVIVE?

  10. INDEPENDENT VARIABLE (I.V.) IS THE ONE THING CHANGED ON PURPOSE. IMPORTANT EXPERIMENTAL VOCABULARY… …REPLACE ONE SET OF DINOSAUR FOOTPRINTS WITH HUMAN FOOTPRINTS…

  11. DEPENDENT VARIABLE (D.V.) COULD BE CHANGED BECAUSE THE I.V. WAS CHANGED. IMPORTANT EXPERIMENTAL VOCABULARY… …AND CHANGE THE SPEED RELATIONSHIP THAT CAN BE DETERMINED BETWEEN THE TWO PARTICIPANTS…

  12. CONSTANT IS A PART OF THE EXPERIMENT THAT STAYS THE SAME. CONTROLIS A TEST RUN OF THE EXPERIMENT THAT DOES NOT CHANGE THE I.V. IMPORTANT EXPERIMENTAL VOCABULARY… THE DATA TO DETERMINE SPEED FOR THE REMAINING DINOSAUR DOES NOT CHANGE…

  13. HYPOTHESIS IS A TESTABLE EXPLANATION. WRITTEN AS AN “IF…THEN…” STATEMENT. IMPORTANT EXPERIMENTAL VOCABULARY… IF DR. GRANT REPLACES A DINOSAURIAN PREY, THEN HE COULD OUTRUN THE DROMAEOSAURS. IF DR. GRANT REPLACES A DINOSAURIAN PREY, THEN HE COULD NOT OUTRUN THE DROMAEOSAURS. -OR-

  14. DESCRIPTIVE STEPS… From OBSERVATION, Identify a QUESTION • WE WILL NEED TO FIND WHAT INFORMATION ABOUT OUR DINOSAUR TRACKS…? RESEARCH the Question

  15. FOR DINOSAURS A AND B: HOW MANY FOOTPRINTS ARE THERE? HOW MANY TYPES OF PRINTS ARE THERE (WALKING ON MULTIPLE FEET)? HOW BIG ARE THE PRINTS? HOW FAR APART ARE THE PRINTS? DESCRIPTIVE STEPS… From OBSERVATION, Identify a QUESTION RESEARCH the Question

  16. PREDICTION - CAN OUR QUESTIONS BE ANSWERED WITH OBSERVATIONS AND BASIC METRIC LENGTH MEASUREMENTS? DESCRIPTIVE STEPS… Form a PREDICTION Gather MATERIALS CHOOSE LAB PARTNERS WISELY…

  17. UNIT = METERS METERSTICKS: 1 STICK = 1 METER LINES 1 FINGER WIDE ARE CENTIMETERS. 100 CENTIMETERS = 1 METER. TINY LINES ARE MILLIMETERS. 10 MILLIMETERS = 1 CENTIMETER. 1000 MILLIMETERS = 1 METER. METRIC LENGTH MEASUREMENT PROCEDURE METER CENTIMETERS AND MILLIMETERS

  18. DESCRIPTIVE STEPS… • DO OUR ANSWERS MAKE SENSE? • DID WE FIND OUR ANSWERS WITH CAREFUL AND COMPLETE OBSERVATIONS AND CORRECTLY-DONE MEASUREMENTS? • OUR CONCLUSIONS WILL BE OUR FINAL ANSWERS. ANALYZE Data CONCLUSION
