The short version

Our simulations are simplified models for learning. They are carefully checked, but they are not exact, and they are no substitute for your teacher, your textbook or a real, supervised lab. Never try a real experiment because you saw it here without an adult or teacher and proper safety equipment.

1. A learning aid, not a replacement

Curiosand helps you visualise and explore ideas in physics, chemistry and maths. It does not replace teachers, textbooks, official syllabi, practical classes or exam preparation from your school or board.

2. Models are simplified

  • Simulations make deliberate simplifications: ignoring air resistance or friction where stated, ideal gases, rounded constants, idealised circuits and so on.
  • Time is often sped up or slowed down, and sizes are not to scale, so that effects are visible.
  • Some chemistry models use low activation energies or simplified kinetics so that reactions happen in seconds; values are labelled where this matters.
  • Numerical methods have small rounding errors. When in doubt, trust your textbook and teacher.

We check our content against standard references and correct mistakes when we find them. If you spot an error, please tell us at [email protected].

3. Safety: virtual only

Simulations of chemical reactions, acids and bases, electrical circuits, high voltages, nuclear processes, heat, pressure or moving objects are virtual demonstrations. Real experiments can cause burns, poisoning, electric shock, fire or injury. Do not attempt any real experiment based on this site except under the supervision of a qualified teacher or adult, with proper safety equipment and procedures.

4. Syllabus and exam links are guidance

We map topics to NCERT chapters and to US standards (NGSS, AP and Common Core) to help you find what you are studying. These mappings are our own interpretation, may not match your school's course exactly, and can change when syllabi are revised. Always check your official syllabus. Using Curiosand does not guarantee any marks, grade or exam result.

5. No affiliation or endorsement

Curiosand is independent. It is not affiliated with, endorsed by or sponsored by NCERT, CBSE, the National Testing Agency (JEE/NEET), the College Board, WestEd or the developers of the Next Generation Science Standards, or the authors of the Common Core State Standards.
