Decoding Prompt 23 – “How important are material tools in the production or acquisition of knowledge?”
IB TOK Exhibition Prompt 23 invites you to examine an often-overlooked truth: most of what we ‘know’ depends on the physical instruments we use to measure, observe and record. From the telescope that revealed the cosmos to the microscope that opened the cellular world, material tools do not merely assist knowledge production — they actively shape it. The prompt pushes you to consider whether tools are passive aids or active agents in determining what counts as knowable.
A top-scoring IB TOK exhibition on Prompt 23 does three things well: it links each object to a specific moment when a tool transformed knowledge, it explains the dependency between the tool and the resulting claim, and it connects to an optional theme or area of knowledge — typically the natural sciences or technology.
TOK Exhibition Objects for Prompt 23
Each example below includes the object, linked optional theme, examiner-written rationale, and a knowledge question to extend your analysis.
The Hubble Space Telescope
The Hubble Space Telescope has revolutionised our understanding of the universe, from the discovery of dark energy to the observation of the most distant galaxies. As a material tool, Hubble exemplifies how technological advancements extend the boundaries of human knowledge, allowing us to acquire information that was previously beyond our reach. This object underscores the significance of material tools in expanding our observational capabilities and providing empirical evidence that shapes our comprehension of cosmic phenomena.

score 8+ on TOK exhibition
The Electron Microscope
The electron microscope transformed biology, materials science and medicine by allowing researchers to observe structures at the nanometre scale — viruses, cellular organelles and crystalline lattices. Before this material tool existed, the knowledge it produces was simply unavailable; afterwards, entire fields reorganised around the new images. This object illustrates how the production of knowledge is not merely supported by instruments but is sometimes wholly contingent on them, raising the question of whether reality itself is co-constructed by the tools we use to look.

- Predicted grade improvement — most students gain 2+ points
The Astrolabe
The astrolabe, used for centuries by Islamic, Greek and medieval European astronomers, allowed users to determine latitude, time, and the positions of celestial bodies. As a material tool, it embodies how communities across cultures produced reliable astronomical and navigational knowledge long before modern instruments existed. This object highlights that material tools are not solely a feature of contemporary science — pre-modern instruments organised observation, encoded knowledge in physical form, and made systematic inquiry possible across civilisations.
Your IA or Extended Essay deadline is coming. Your draft isn’t top-band yet.
Internal Assessments and the Extended Essay carry serious weight in the final IB score — yet most students submit drafts that lose easy marks on structure, data analysis, and referencing. Sev7n’s examiners review every draft against the official IB rubric before you submit.
- Topic selection & research-question refinement
- Rubric-mapped feedback on every draft (Criteria A–E)
- Data analysis, methodology & referencing support
- Final polish to push your IA from a 5 to a 7
What Parents & Students Say About Sev7n
Hear directly from IB parents about how Sev7n transformed their child’s IB journey — from predicted 4s to final 7s.
My daughter was struggling with TOK exhibition and Chemistry HL — predicted 4s in both. After 4 months with Sev7n’s examiner tutors, she scored a 7 in Chem and 9/10 on exhibition. The LMS dashboard kept me in the loop every week. Worth every rupee.
We tried three big coaching centres in Dubai before finding Sev7n. The difference: actual IB examiners, not generic teachers. My son’s Economics HL teacher here has marked IB papers for 8 years. Game-changer for his IA and predicted grade.
What I love most is the auto-recorded sessions and weekly parent reports. I’m a working mom and can’t hover over my daughter’s shoulder — Sev7n’s LMS makes it easy to stay informed without being intrusive. TOK essay went from 3 to 8.
The free demo class itself was more useful than months of IB support elsewhere. The tutor didn’t just teach — she diagnosed exactly where my son was losing marks on Paper 2. Honest, professional, and genuinely examiner-level. Signed up the same day.
Our Singapore time zone was always an issue with Indian tutors. Sev7n matched us with a tutor who’s based in the UK and teaches in our window. My daughter’s Maths AA HL went from a predicted 5 to 7 in 6 months. Can’t recommend enough.
We’ve worked with 4 different TOK tutors before Sev7n. None came close. Their examiner gave my son a detailed marksheet mapped to the IB rubric — something no one else did. Final TOK essay: A (predicted C). That grade just saved his university offer.
2 More Objects for Prompt 23
Two additional examiner-written object examples to help you finalise your TOK exhibition selection.
A Modern Supercomputer Cluster
Supercomputer clusters power climate models, protein-folding simulations and large language models, producing forms of knowledge that no human mind could compute unaided. As a material tool, the supercomputer expands not what we observe but what we can infer, model and predict. This object illustrates how knowledge production is increasingly reliant on computational machinery, prompting reflection on whether knowledge generated by simulation and statistical inference is epistemically equivalent to knowledge generated by direct observation.
Tired of one-size-fits-all coaching centres that don’t really know IB?
Sev7n’s proprietary LMS pairs you with an examiner who’s actually marked IB papers. Every class is live, every session is recorded, and every parent gets a weekly progress report — all on one clean platform built for IB families.
- 100% live 1:1 or small-batch classes (never big-class chaos)
- Every session auto-recorded — rewatch, revise, repeat
- Weekly WhatsApp progress reports for parents
- Flexible time zones — tutors across India, UK, UAE, Singapore
A Standard Laboratory pH Meter
A laboratory pH meter, used in classrooms and research labs worldwide, exemplifies how routine material tools quietly underpin everyday knowledge production. Without standardised, calibrated instruments like the pH meter, replicable measurement — and therefore the empirical foundation of chemistry — would not exist. This object shows that the importance of material tools is not confined to landmark discoveries; reliable knowledge depends on a vast infrastructure of unremarkable, well-calibrated instruments that make consistent observation possible.
Your school teacher can’t mark IB exam papers. Our tutors can.
There’s a massive difference between someone who teaches IB content and someone who actually marks IB exam scripts. At Sev7n, 170+ of our tutors are IB-certified examiners — which means they know exactly what scores, and what doesn’t.
- Verified IB examiners — not just IB teachers
- Deep rubric knowledge across HL, SL & all assessment objectives
- Insider insight into common examiner mistakes students make
- Personalised feedback that matches real IB markschemes

Knowledge Questions for Prompt 23
Use these knowledge questions to strengthen the analytical depth of your exhibition commentary.
Are material tools merely passive aids, or do they actively shape what counts as knowledge?
Can knowledge produced through instruments be considered as direct as knowledge gained through unaided senses?
How does dependence on a tool change the relationship between knower and known?
Do measurement instruments bring objectivity, or do they introduce their own kind of bias?
What happens to a body of knowledge when its underlying instruments become obsolete?
Can pre-modern tools like the astrolabe sit alongside modern instruments as legitimate sources of knowledge?
How to Score High on Prompt 23
Three strategies our IB examiners use when coaching students through the TOK exhibition.
Choose tools that visibly transformed a field
Hubble for cosmology, the electron microscope for biology, the astrolabe for navigation. Examiners reward objects with a clear ‘before-and-after’ impact on knowledge.
Explain the dependency, not just the existence
Don’t just say ‘the microscope helped science’. Explain what specific knowledge was impossible without it. Top-band commentary makes the dependency explicit.
Mix scales of importance
Pick at least one mundane tool (a pH meter, a ruler) alongside a glamorous one (Hubble). The contrast lets you argue that knowledge depends on tools at every scale, not just at the frontier.
