Internal Assessment Lab Format

The following titles and subtitles should be used for your lab report and given in this order within

your lab report.

Design

Question

must be focused and not ambiguous in any way. If a living

–

organism was used, identify it by common name and scientific name.

Hypothesis –

state your hypothesis first & then give a logical rationale – your

conclusion should address the hypothesis you are giving here.

Variables –

create a chart or list identifying the Independent, Dependent, &

Controlled Variables (be specific; room conditions is not acceptable)

Example:

Independent Variable

Dependent variable

Control variables (5

minumim)

Protocol Diagram –

draw & label a diagram which best shows the major

protocol(s) you will use. Often this will focus on the technique that is used to

measure the dependent variable and/or the technique that is used to ‘setup’

different increments of the independent variable. Make sure to show how control

group(s) differ from experimental group(s). This is also where I want you to

emphasize the inclusion of a period of time for ‘equilibration’ of equipment, fluids,

organisms, etc. The inclusion of time periods for equilibration should also be

included in your written procedure.

Photograph of Lab Setup (only if you actually carry the lab out) –

annotate this to show how variables were instituted, especially the controlled

variables. Do not just label equipment. This is the section that I use to decide if

your procedure properly institutes the variables that you have identified in a chart

or list above.

Procedure –

write in numbered, list form, passive voice, and read like

directions for the procedure. Detail should allow repeatability. You should ensure

that your procedure includes at least 5 independent variable “intervals” {5 temps,

5 pH’s, 5 concentrations, etc} and also includes a minimum of 5 repeats {trials}.

You must also collect some data that is qualitative (in a numbered, titled data

table), for example, you could report that a person’s ventilation (breathing) rate

appears elevated in addition to the collection of a quantitative heart rate

measurement.

To receive full marks for the design you MUST include the data tables that

will be needed for DCP. You should have 3 (raw data, control variable data,

and qualitative data)
