Experimental Cycle [and other diagrams]
This graphic of the Experimental Cycle is adapted from the IB’s MYP Sciences Guide assessment descriptors (2014), using GoogleDrawings. The experimental cycle is a visual representation of the process of a lab inquiry – and also of the stages of a lab report for the ‘Inquiring and Designing’ and ‘Processing and Evaluating’ assessment criteria. It can help structure a lab, but make sure you get hands-on!
This version has been adapted further for MYP1, with guiding questions:
Sentence Stems: We Are All Language Teachers
These were created to give a linguistic support to inquiry in science.
- For EAL learners, they provide vocabulary and a starting point.
- For all learners they are a way into the language of science.
We used them as printed inserts in physical student lab-books, and found best gains in keeping the students off laptops for as long as possible, holding them to full-sentence response in speech and writing. We have to act (or speak, write) our way into a new form of thinking.
I don’t advocate for these being used alone and forever, though. Once students are confident in them, they will want to use their own formats or phrases. We had students who were ready for more sophisticated language after one or two cycles, and others that needed support for longer. These cycles and stems are intended for “get going quickly and let go quick” learning and support.
Having a printed structure like this should increase student inquiry and thinking, not decrease it. Knowledge is the stuff we think with: fluency in the foundations is a jumping-off point for us to support student thinking. This is a differentiation tool. It should not be boiled down to a form-filling formula.

The Importance of Play
Please, if you use these with students, try to emphasise the importance of “play” in science.
It is entirely possible to spend a long time writing a lab report to meet the requirements (on paper), only for the method be unworkable.
Are we inquiring through science… or “doing lab reports”?
In the early stages of lab design we can take more of a design-cycle approach: get hands-on with the equipment, try to actually manipulate the IV and see if the idea can even work before committing it to computer-work (or worse, homework).
Consider thinking about the structure and sequence of your course. Physical sciences lend themselves to quicker investigations than Biology and so might suit the start of the year, for example.
What can we do to get students hands-on, minds-on as soon as possible, to manipulate variables and see the cycle at work?
High-Tech, Low-Tech, No-Tech?
In the early stages of a lab, I keep students off the computer for planning. They might use it for research, but I much prefer that they don’t start “writing the report” before the data are collected.
Instead, we use a paper section (sample here) or lab-books to:
- Keep the thinking focused on the science
- Sketch ideas and graphs, and justify our reasoning
- Test ideas practically (importance of play), before sitting to write
- Keep expensive laptops safe and dry and workspaces clear of clutter
Students will show me their method outline, table ready for data and safety considerations before they collect the data. Once their data are recorded, we look at them together, scanning for anomalies or problems before setting off on the spreadsheet and then the write-up.
