GO TO THE INTERNET RESOURCES AND CD’S FOR MORE 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
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

Making wet mount
Appearance of objects
Movement of objects
Magnification
Changing objects
Estimating size of objects
Field diameter & area
Determine the diameter of the field and the length of one cell in mm and convert to mcm.

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 !!!!!
Meniscus – read bottom
Capacity and Range
Graduations – numbered and unnumbered increments
Readability
Making measurements
Estimating
Capacity and Range
Numbered and unnumbered increments cm vs mm
Uses of each
Making measurements
Estimating
Vernier Scale
Capacity and Range
Do not start at zero
Numbered and unnumbered increments
Uses of each
Making measurements
Estimating
Identify range, capacity, incrementation
Do measurement – estimate last digit
• 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.
Capacity – auxillary weights
Units – numbered and unnumbered increments

Data Presentation and Analysis-
Graphs
Graph – types
X vs Y axis
Scaling axis
Plotting points
Human Error
Curve or best fit line
Labeling
Measure sample area
Determine population density for symbols
Assign an organism to symbols
Form a food chain
Evaluate sample – predict techniques, etc.
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
Analyze the design of the experiment
Identify variables
Explain results – form conclusions
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 – 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 . . 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.
Have specimens of leaves
Formulate a key or use a key to identify specimens
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 !!!
