Title – keep it fairly general and simple
Purpose – usually copied from the lab
Claim – a factual statement of the labs findings (e.g. The sand, salt, and water are mixtures.)
Materials – list of equipment and things used in the experiment (just edit this table)
250 mL Beaker
100 mL Graduated
Cylinder
Digital Balance
Hot Plate
Salt
Sand
Glass Thermometer
Tap Water
Procedure – a numbered list of step followed in the experiment (this is an example)
1.
Mass 2 grams of sand
2.
Place sand in 250 mL Beaker
3.
Measure 60 Ml of tap water with a 100mL graduated cylinder
4.
Pour the tap water into the 250 mL Beaker with the sand
5.
Mass 2 grams of salt
6.
Place salt into the 250 mL beaker with the sand and tap water
7.
Stir the mixture until the salt is dissolved
Data (evidence) – a table or tables that include all the important measurements and/or observations
(just edit the table to suit the needs of the data and/or observations)
Trial Number Mass of Sand Mass of Salt
Pictures (evidence) – Paste pictures here from whatever source being used. DO NOT paste pictures that are not generated by the report author/authors!
Calculations (evidence) – show all work, label what is being calculated, include the units in the work and in the answer, and round the final answer to correct significant figures.
Graphs (evidence) – if required by the experiment, maybe obtained from software as a picture
Conclusion (reasoning) – this is the answer to the claim of the experiment. There must be references to the data table or tables, calculations, and or graphs to support the conclusion. (Start the conclusion by restating your claim, eg. The sand, salt, and water are mixtures._)

Known result and/or percent error – some labs will require the comparison of the labs experimental result and a known measurement, for example the density of the element copper.
