HELP!? Biology Prac Write Up Portfolio? (1 Viewer)

[LaurenTaylah]

So I have to write up one prac from each topic I have studied in bio and put all three into a portfolio. Only problem is that we haven't been given an example on how to correctly write up prac's to a high standard.

If anyone has a scaffold of how to write up bio prac's can you please contact me ASAP and you can either link me to it or I will give you my email and you can email it too me.

Help would be very much appreciated!!
Thank you!!

Do you mean:

Aim:
Hypothesis:
Materials:
Safety:
Method: include all 3 variables (independent, Dependent, Control)
Results:
Discussion:
conclusion:

Do you need more info... is so elaborate

Dont forget a title

General Experiment Guidelines, Graphing and Validity/Reliability-

AIM-Clearly link the two variables
HYPOTHESIS- If (X is changed) then this outcome will occur for dependent variable
Identify the Independent and Dependent Variable
METHOD:
Equipment and Materials

Diagram- GREY LEAD and RULER

Step by step method: Numbered bullet points, no lengthy prose

Control: For comparative purposes, why you have used particular control

Controlled variables-(listed)

Risk Analysis: Aim to be specific to experiment

RESULTS: How would you show your experiment data?

Data table: Draw a table with column for independent and dependent variable, with space for average of repetitions
Graph: Linear scales, scales labelled, correct plotting, correct variable on axis with units(INDEPENDENT on x axis, DEPENDENT on y axis), correct selection of line/bar (TWO continuous variables= LINE graph, ONE DISCONTINUOUS=BAR graph), Title, Key

DISCUSSION: Address findings and what appeared to be result. Discuss;
Y Possible improvements
Y VALIDITY-Did experiment test hypothesis that you wanted it to? Were necessary variables identified and controlled? In secondary sources: How was the information gathered and what methods were used by the researchers?
Y RELIABILITY- Have I tested with repetition? Have I used a sufficient range of values for my independent variable for a pattern to be clearly revealed? In secondary sources: Is the information consistent with other reputable sources information?

CONCLUSION:
What did we find out?
Accept or reject hypothesis
What patterns and trends e.g high/low points, linear relationship, averages, any outliers/anomalous results and the reasons for them? Any other issues?

So for prac suggestions, definitely use one of the pracs on enzymes from MAB, I had all three written up. For BOL, I suggest the modeling of polypeptide synthesis. And for SFBH, performing Pasteur's experiment would be a good write up imho.

Title of Experiment: short title of what your experiment is e.g. Effect of Substrate Concentration on the Enzyme Activity

Aim: State what are you are investigating

Hypothesis (optional): Your prediction of how one variable will affect another (how the independent variable will affect the dependent variable)

Materials/Equipment: A list of all the equipment/materials you need - be specific, e.g. don't say "beaker" specifiy whether it's a 100mL beaker or 500mL beaker

Risk Assessment: Are there any dangers/safety hazards? Draw up a table with 3 columns: substance of risk, nature of risk, and safety procedures

Method: Describe the steps involved in the investigation in past tense. Make sure it's easy to follow and be specific. Dont just write "add water to the beaker", instead say "add 100mL of water to the beaker"
If there's a control experiment, include what you're doing different to the actual experiment and why.
Variables:

Independent: what you're changing e.g. if you're testing the effect of temperature on enzyme action, the temperature is the independent variable.​

Dependent: what you're measuring​

Controlled: everything you're keeping the same​

Results: A table for numerical data, and include graphs if appropriate. Also, choose the right graphs (use a line graph when you want to observe changes over a period of time (continuous) and show relationships/trends, and use a column graph when you want to compare the frequency of different groups/categories) For graphs, the independent variable is on the x-axis and the dependent is on the y-axis. Make sure you label the axis and give your graph a title. Also include appropriate scales in your graphs. For results, you can also draw diagrams e.g. the blood cells prac - draw both the red and white blood cells.

Discussion: Analyse your results - what do they show? Also, justify the proceduce/equipment you used. Were there any problems that occurred or might have occurred during your experiment, if so, how would you fix these problems if you could? Assess the validity (did your experiment test what it set out to test?) , reliability (did you repeat the experiment and compare your results with your own trials and other other people's experiments, did you obtain similar results or were there discrepancies? For numerical data, did you obtain an average to minimise the effect of insignificant errors?) and accuracy (did you measure things accurately e.g. did you use a measuring cylinder to accurately measure the amount of water you needed or did you "eyeball" it) of your experiment. You might include whether this investigation is better carried out individually or as a team.

Conclusion: Sum up what happened in the experiment, were there any trends/relationships/patterns (and if there were, what do they suggest), was your hypothesis (if you had one) accepted or rejected?

Examples of pracs you can use:
Maintaining a Balance: the enzyme pracs, investigating blood cells, xylem and phloem prac
Blueprint of Life: Modelling natural selection (with models you can also talk about limitations/advantages of models in your discussion).
Search for Better Health: Identifying microbes in food/water or pasteur's experiment.
