How science concept maps help you study

Concept maps help science students see how ideas connect, such as how enzymes, substrates and reaction rates depend on one another. DeckOwl turns your own lecture slides or notes into science concept maps you can edit and explore branch by branch.

  • Shows cause and effect, not just a list of terms
  • Keeps vocabulary consistent with your class material
  • Lets you reorganize a topic as your understanding grows
  • Works with a flashcard or quiz step when you want to practice recall

Built from your own material

Start from your lecture slides, textbook chapter or class notes instead of a generic template.

Editable and explorable

Rename branches, move ideas and expand or collapse sections to focus on what you are studying.

Study from the same map

Turn a map into flashcards or a quiz so the connections you practice match the ones you learned.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a printed page.

Generate the map

DeckOwl reads the text and arranges the main concepts into branches with sub-points.

Edit and explore

Adjust labels and layout, then click through each branch to test your understanding.

Because the map comes from your course material, it follows your instructor's terms and emphasis. Review it before an exam, then fill in any gaps by adding sub-points or linking related ideas yourself.

Frequently asked questions

What should a science concept map include?

Focus on the core terms, the processes or laws, and the links between them, such as cause and effect. Keep each label short so the connections are easy to read.

How do I decide which branches to start with?

Begin with the main headings from your chapter or lecture, then add sub-points only where a link matters for the exam. If a branch grows too crowded, split it into its own map.

Can I export the map?

Exporting is a paid feature. The free plan lets you study in the browser, while the paid plans include export options.

Does it work with photos of lab notes or slides?

Photos of pages are read with text recognition, so clear, well-lit images of printed text give the best results.
