Bio PAT skills

Question 1

What should your method include?

Answer 1

FIDOELVR: Fixed Variables, Independent Variable, Dependent Variable, Originality, Equipment, Layout, Validity, Results (say WHAT)

Question 2

How are you supposed to use a syringe?

Answer 2

• eye level
• push out liquid and flick bubbles
• always overfill

Question 3

How are you supposed to use a thermometer?

Answer 3

• don’t touch bottom of beaker
• bring to eye level

Question 4

Differentiate between the IV and DV.

Question 5

CALCULATING CONCENTRATION FORMULA???

Answer 5

Concentration of test tube/ concentration of concentrate x volume of test tube = volume of concentrate

Question 6

How do you make an experiment accurate?

Answer 6

Maintain fixed variables (eg. Time, temperature — never room temp — and volume.) NEVER SAY AMOUNT OF. NEVER REPEAT VARIABLES. BE SPECIFIC. ALWAYS OPT FOR SOLUTION OVER SOLUTES/SOLVENTS.

Question 7

How do you make an experiment reliable?

Answer 7

Repeat the experiment/ increase the sample size of.the.same.variable!!!/ add a control

Question 8

What do you have to watch out for in terms of tables?

Answer 8

«Colour change»: one column
« colour before and after»: two columns

IV & DV 2
HEADING HAS TO BE SPECIFIC

Question 9

What do you have to watch out for in terms of concentration methods?

Answer 9

Always ensure the amount of liquid in the beaker /test tubes is the same in all of them.

Question 10

What does «improving the design of an experiment» entail?

Answer 10

It’s subjective. Include other factors relevant to the actual experiment.

Question 11

How do you answer what the purpose of a «control» is?

Answer 11

TO !!!!COMPARE!!!! to the

either the IV to ensure its due to that; to compare to use as a benchmark to see, comparison of results to see what

Question 12

Qualitative vs Quantitative

Answer 12

Quantitative: Numerical values, no senses used
Qualitative: No numerical values, senses used (can specify which one)

Question 13

Writing an aim

Answer 13

To determine/investigate…
I.V effect on D.V as seen by…

Question 14

Writing a hypothesis

Answer 14

• one sentence
• not necessary for a reason why?
• IV and DV, as seen by

Question 15

How do you answer fixed variable questions?

Answer 15

• what, how much, how, using what

Question 16

How do you work accurately with a scale?

Answer 16

• zero it at the beginning

Question 17

What are the 3 types of microscopes and how do you identify which it is?

Answer 17

• SEM (surface)
• Transition Microscope (slice)
• Light Microscope (not extremely magnified, in colour, not much detail)

Question 18

Biological drawing headings: how would you go about this?

Answer 18

Biological drawing of a cross section/longitudinal section of blah blah (50X)

Question 19

What is the long formula for Actual Size?

Answer 19

Length x number on scale bar / length of scale bar
