2 Event Rules – 2015 DISCLAIMER This presentation was prepared using draft rules. There may be some changes in the final copy of the rules. The rules which will be in your Coaches Manual and Student Manuals will be the official rules.

3 Event Rules – 2015 BE SURE TO CHECK THE 2015 EVENT RULES FOR EVENT PARAMETERS AND TOPICS FOR EACH COMPETITION LEVEL BE SURE TO CHECK THE 2015 EVENT RULES FOR EVENT PARAMETERS AND TOPICS FOR EACH COMPETITION LEVEL

4 TRAINING MATERIALS Training Power Point – content overview Training Power Point – content overview Training Handout - content information Training Handout - content information Practice Activities - sample stations with key Practice Activities - sample stations with key Sample Tournament – sample problems with key Sample Tournament – sample problems with key Event Supervisor Guide – prep tips, event needs, and scoring tips Event Supervisor Guide – prep tips, event needs, and scoring tips Internet Resource & Training CD’s – on the Science Olympiad website at under Event Information Internet Resource & Training CD’s – on the Science Olympiad website at under Event Informationwww.soinc.org Biology-Earth Science CD, Bio-Process Lab CD (updated 2015) in Science Olympiad Store at Biology-Earth Science CD, Bio-Process Lab CD (updated 2015) in Science Olympiad Store at

5 Bio-Process Lab (B) Event Description - lab-oriented competition involving the fundamental science processes of a middle school biology lab program Event Description - lab-oriented competition involving the fundamental science processes of a middle school biology lab program Event – lab practical in stations Event – lab practical in stations be sure to check the rules for resources allowed, type of goggles needed. Event Parameters – be sure to check the rules for resources allowed, type of goggles needed.

6 Basic Science Process Skills Observing Observing Measuring Measuring Inferring Inferring Classifying Classifying Predicting Predicting Communicating Communicating

7 Integrated Science Process Skills Formulating Hypothesis Identifying Variables Defining Variables Operationally Describing Relationships Between Variables Designing Investigations Experimenting Acquiring Data Analyzing Investigations and Their Data Understanding Cause and Effect Relationships Formulating Models

8 GAME PLAN POWERPOINT FOR OVERVIEW HANDOUT FOR DETAIL OF INFORMATION NEEDED INTERNET RESOURCES AND CD FOR MORE HELP PRACTICE ACTIVITIES TO MASTER SKILLS SAMPLE COMPETITION UNDER TIMED CONDITIONS TO EXPERIENCE COMPETITION SITUATION

19 Probes Graphing calculator Graphing calculator Easy link or CBL Easy link or CBL Probe Probe Collect data onto calculator Collect data onto calculator Transfer data to computer Transfer data to computer Graph analysis Graph analysis Quick data collection Quick data collection

20 Data Presentation and Analysis- Data Tables Format Format Title Title Units of measurement Units of measurement Numbering Tables Numbering Tables Source Source Leg (thigh) Length (cm) Time of 40 yard dash (sec)

21 Data Presentation and Analysis- Graphs Graph – types Graph – types X vs Y axis X vs Y axis Scaling axis Scaling axis Plotting points Plotting points Human Error Human Error Curve or best fit line Curve or best fit line Labeling Labeling

22 Human Mistakes vs. Experimental Errors Human Mistakes – carelessness Human Mistakes – carelessness Experimental Error – instrument variation or technique Experimental Error – instrument variation or technique Random Error – chance variation Random Error – chance variation Systematic Error – system used for designing or conducting experiment Systematic Error – system used for designing or conducting experiment

23 A Sample Dichotomous Key 1. wings covered by an exoskeleton go to step 2 1. wings not covered by an exoskeleton.... go to step 3 2 body has a round shape ladybug 2 body has an elongated shape......grasshopper 3.wings point out from the side of the body.. dragonfly 3 wings point to the posterior of the body..... Housefly Note: There should be one less step than the total number of organisms to be identified in your dichotomous key.

24 Sample Stations – Population Density Measure sample area Determine population density for symbols Assign an organism to symbols Form a food chain Evaluate sample – predict techniques, etc.

25 Sample Station – Dichotomous Key Have specimens of leaves Formulate a key or use a key to identify specimens

26 Sample Station - Measurement Identify range, capacity, incrementation Do measurement – estimate last digit

27 Sample Station – Experiment Analysis Analyze the design of the experiment Identify variables Explain results – form conclusions

28 Sample Station – Microscopy Determine the diameter of the field and the length of one cell in mm and convert to mcm.

29 Sample Station – Data Analysis Making hypotheses Making hypotheses Food web analysis Food web analysis Eating habit analysis Eating habit analysis Predictions and conclusions Predictions and conclusions Inferences Inferences

30 Sample Station – pH Determine the pH of various solutions using either pH probe or pH test papers.
