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
Tare Using the Balance Advantages &
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 !!!
