Data Analysis and writing great Science Reports

This page is about understanding how to interpret data in order to write a great science report. Most of the links below are related to writing an experimental report, but there is one to an exemplar research assignment. The links below show different levels of work, from beginner (middle school) to more expert levels (senior sciences).

Data analysis for beginners

A detailed but simple (for advanced junior students) explanation of how to analyse data. The point of view is to show middle school students how data is evaluated in senior school. very much laying the groundwork, so that the students become more comfortable with the senior style of analysis. This is NOT a how to write a report document, just what I use in my advanced junior classes to complete some class exercises in data analysis.

Examples of data and data analysis in the middle school

Data sets
I have used in class(*) and some I have not used yet. Note, this work suits advanced students mainly.

*Simple data on sugar and respiration Great one to start with, simple and a general science idea which does not require much teaching.

*Leaf temp and light intensity effect on photosynthesis. Two sets of data in this one. You could do them each as separate data sets.

The effect of salt on osmosis in potatoes. This is data my yr 8 class (a very advanced year 8 class) collected and analysed.

GPE and KE task and data (experiment). This was an other experiment my yr 8 class did and wrote data analysis for. An exemplar for the class is below.

REd foxes and predation. This is complicated data but shows tremendous connections between the data sets. Did not use in class.

Microbial growth rates. very complicated data - for exeptional middle school students, or senior students.

Examples of Data analysis using the data above. Take note, these are not perfect, I have often taken short cuts to keep the word length down. But they are exemplars for Junior school( up to year ten) If you are in senior school and using these to get a start, then you must realise there needs to be more use of data to support decisions and conclusions.

Analysis of the sugar and Respiration data.

Analysis of the leaf temp and light intensity on photosynthesis.

Analysis of the Salt in Potatoes data. This was written by one of my yr 8 students and I typed it up. Absolutely outstanding work.

The GPE and KE task, with data analysis added.

Exemplar of a student investigation

A student investigation exemplar. Read this - I use this exemplar widely, with a range of classes as it is hard to provide a range of exemplars written at different levels. I edit it (for example, drop out the error proagation), depending on the class I am using it for. It is an excellent exemplar for beginning senior school students (yrs 10 and 11) - of course that is my opinion only! This exemplar is fairly dated, and I would love to write one speciffically for senior students, but coming up with a simple topic which cannot be used by a student is difficult. I managed it with the research investigation (see below), but am stuck for a topic for an experiment report.

Senior School guide to writing a student investigation

Write a GREAT student experiment 2021.docx This has been reedited and hopefully improved. Less complex language and more approachable.


The best pet for you. See disclaimer below.
READ THIS - This is a senior school research Investigation. It is on dogs versus cats. This may sound like a weird topic, but I needed something that a senior science student could relate to (so, simple idea), but not a topic that a student could actually use for their own research investigation.
My biggest gripe with students is that they do NOT write to the criteria. My exemplar is not supposed to be a "great" assignment, it is designed to meet every criteria - and in the QCAA model, that is what you need to do.
The article will open in the review pane on micrsoft word. I have included comments for almost all the paragraphs explaining what and why I do things. Essentially, I give a blow by blow explanation of how I meet all the criteria. It's not you I would have liked more time. But this has been drafted about 3 to 10 times (depending on the section), so I am willing to live with the errors present. Please feel free to let me know if you identify any major errors.
And yes... it is nearly 2400 words. I can lose several paragraphs which are not needed (i included them as examples of work which are pretty common, but just not relevent to the data i used in this investigation). I would also trim the description of the data sources by removing authors and rewording.
