Data Analysis and Science Reports

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.

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.

A student investigation exemplar. Read this - I use this exemplar widely, with a range of junior school academic classes (yrs 9 to 10). I edit it (for example, drop out the error proagation), depending on the class I am using it for. This exemplar is fairly dated, but will not be updated in the near future (or, to be honest, ever!)

The best pet for you. See disclaimer below.
PLEASE READ THIS - VERY IMPORTANT. - This is a senior school research Investigation. It is based on a claim "dogs are better than cats". This may sound like a weird claim, 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.
The first key step is to understand the claim and break it down to possible RQs. I took the idea of dogs are better than cats (my claim), and went to AI. By asking various Qs of the AI, i got the idea of owning a dog was benefitial to their owners. This gave me the basic form of my RQ - pet dogs versus pet cats in terms of benefit to the owner. Time for step 2.
The second key step is finding data which allows you to be "specific". I found data which allowed me to narrow the "benefit" idea (too broad) into 2 specific criteria. Now I had data, and a specific and relevent RQ. Time for step 3.
The third key step is simply writing the 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 try to meet all the criteria. It's not perfect...like you I would have liked more time. But this has been drafted up to 10 times (depending on the section), so I am willing to live with the errors present.
And yes... it is long. I have not done the final few steps of drafting which is to cut down to the word limit. Also, I have written several paragraphs which are not needed, but are examples of work which are pretty common for students.
