Event Rules – 2016

DISCLAIMERThis 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.

Event Rules – 2015

BE SURE TO CHECK THE 2016 EVENT RULES FOR EVENT PARAMETERS AND TOPICS FOR EACH COMPETITION LEVEL

TRAINING MATERIALS

Training Power Point – content overview Training Handout - content information and needed

skille Practice Activities - sample stations with key Sample Tournaments – sample problems with key Event Supervisor Guide – prep tips, event needs, and

scoring tips Internet Resource & Training CD’s – on the Science

Olympiad website at www.soinc.org under Event Information

Biology-Earth Science CD, Bio-Process Lab CD (updated 2015) in Science Olympiad Store at www.soinc.org

Biology lab manuals – identify variables and evaluate the labs – become familiar with typical bio labs

Bio-Process Lab (B)

Event Description - lab-oriented competition involving the fundamental science processes of a middle school biology lab program

Event – lab practical in stations Event Parameters – be sure to

check the rules for resources allowed, type of goggles needed.

HELP DO THE PRACTICE ACTIVITIES TO MASTER SKILLS DO THE SAMPLE TOURNAMENTS UNDER TIMED

CONDITIONS TO EXPERIENCE COMPETITION SITUATION DO OLD TOURAMENTS– PRACTICE, PRACTICE, PRACTICE THE KEY TO SUCCESS – THE BEST WAY TO LEARN THE

SKILLS IS BY DOING

Student Preparation Team work skills – work as a team Many mistakes are made when work is split to save time – results in many errors Time limits – invest in a timer and practice using it Check station setups – to see what is available to

help you Answering questions – see student preparation

guide Be sure to read questions and do all parts requested Measurement and Calculations – check graduations

and remember units Reference materials – make them functional for

competition under timed conditions Practice, Practice, Practice using the skills you have

learned

Compound Microscope

Parts Making wet mount Appearance of

objects Movement of

objects Magnification Changing objects Estimating size of

objects Field diameter &

area

Principles of Microscopy

Measuring Objects under Microscope

Sample Station – Microscopy

Determine the diameter of the field and the length of one cell in mm and convert to mcm.

Stereomicroscope Parts Appearance of

objects Magnification Advantages Uses Observing

objects

Examining Instrument Graduations Before Measuring

• Capacity- highest it will read – starts at zero• Range if does not start at zero as thermometer• Numbered Increments (graduations) • Unnumbered Increment (graduations)

MANY ERRORS ARE MADE BECAUSE STUDENTS DO NOT EXAMINE THE GRADUATIONS BEFORE MEASURING !!!!!

Sample Station - Measurement

Identify range, capacity, incrementation Do measurement – estimate last digit

Triple Beam Balance with Weights

• Expands capacity of the balance from 610g to 2610 grams • 2 weight equivalent to 1000 g and 1 weight equivalent to

500 g• Actual mass of weight is listed on the top of the weight.

Triple Beam Balance

Capacity – auxillary weights

Units – numbered and unnumbered increments

Disadvantages

Electronic Balance

Capacity Units Tare or Zero Err Using the Balance Advantages &

Disadvantages

Probes

Graphing calculator

Easy link or CBL Probe Collect data onto

calculator Transfer data to

computer Graph analysis Quick data

collection

Sample Station – pH

Determine the pH of various solutions using either pH probe or pH test papers.

Data Presentation and Analysis-

Graphs Graph – types X vs Y axis Scaling axis Plotting points Human Error Curve or best fit

line Labeling

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.

Experimental Analysis

Identify variables Examine procedure – will it evaluate

allow the hypothesis to be tested? Evaluate observations to understand

what happened and why Analyze data and identify errors Determine if the hypothesis is true – if

false what was not considered? Propose further testing or new

hypothesis

Sample Station – Experiment Analysis

Analyze the design of the experiment Identify variables Explain results – form conclusions

Data Analysis

Use observations to understand what happened during the experiment

Look for possible types errors Look for patterns in the data Do data analysis as mean,

median, mode Examine group vs. class results

data Use data to evaluate hypothesis

Sample Station – Data Analysis

Making hypotheses

Food web analysis

Eating habit analysis

Predictions and conclusions

Inferences

Human Mistakes vs. Experimental Errors

Human Mistakes – carelessness Experimental Error –

instrument variation or technique

Random Error – chance variation

Systematic Error – system used for designing or conducting experiment

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 . . dragonfly3 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.  

Sample Station – Dichotomous Key

Have specimens of leaves Formulate a key or use a key to identify

specimens

Key to Success in Bio-Process Lab

Learn the Skills – using Practice Activities

Practice under Timed Conditions Work as a Team – saves time and

catches errors Pay attention to details – avoid silly

mistakes Relax and let the competition show

you how much you have learned Have fun !!!
