Quizizz-style practice on liquid drops from your own notes
Upload a PDF, slides or typed notes about surface tension and droplets, and get multiple-choice, true/false or open questions with explanations.
What a liquid drops quiz should test
Liquid drops hold their shape because surface tension pulls molecules at the surface inward, and that pull makes a free drop as close to a sphere as its volume allows. A quizizz-style quiz on liquid drops works best when it asks you to explain these causes, not just recall the word surface tension.
- Multiple-choice, true/false and open questions with explanations
- Questions generated from your own PDFs, slides and notes
- Free plan includes 3 generations per month, studied in the browser
- Plus and Pro add exports for PDF, DOCX, Moodle XML and QTI 2.1
Questions from your material
Upload PDFs, DOCX files, slides, plain notes or photos of a page. The quiz uses the wording and examples from your own class material.
Explanations for every answer
Each question comes with a short explanation, so a wrong answer teaches you why surface tension or cohesion produced the result.
Exports when you need them
Plus includes PDF and DOCX export. Pro adds QTI 2.1 and Moodle XML for learning management systems.
How it works
Add your notes
Upload a PDF, slides, a DOCX file or paste text from your liquid drops lesson.
Choose the question type
Pick multiple-choice, true/false or open questions, then generate the set.
Practice and review
Answer the questions in the browser, read the explanations and repeat the ones you missed.
Good practice questions connect cohesion, which holds water molecules together, with adhesion, which attaches water to other materials like glass or leaves. Ask yourself why a drop beads on wax and spreads on clean glass, and check whether your answer names the forces involved.
Study the same material in several short sessions. Review the explanations for questions you missed, then try the same idea in a new format, such as a true/false statement or an open question.

Frequently asked questions
Why are liquid drops round when they fall?
Surface tension makes a free drop reduce its surface area for a given volume, and a sphere has the smallest surface area for that volume. Air resistance and gravity can distort larger drops, which is why very big drops flatten.
How do I study surface tension for a test?
Explain the cause of surface tension in your own words, then compare it with adhesion and cohesion using examples like water on glass and water on wax. Practice with questions that ask why, not only what.
Can I export the quiz?
Exports are paid features. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML export.
Is there a free plan?
Yes. The free plan includes 3 generations per month and studying in the browser, but no exports. You do not need a credit card to start.
