On which path will the ball reach the ground first?
We are rolling two similar balls on two different paths: one is a curve, the other is straight. On which path will the ball reach the ground first?
Which Pen will fall first?
We placed two ends of pens on a glass surface and a rough surface. Which pen is more likely to fall when the scale support is removed? Can you guess which pen will fall first?
Using Math to predict orientation of bottle caps
We threw 600 caps on the floor. Can you predict their orientation?

We burned two papers, one attached to a wooden plate and one attached to a Copper plate. Which paper would burn first? Lets use Physics to understand.
Which Pen will fall first?
Wow! Congratulations!
We placed two ends of pens on a glass surface and a rough surface. Which pen is more likely to fall when the scale support is removed? Can you guess which pen will fall first?
Which ice would melt first?
Wow! Congratulations!
We froze the same quantity of water to make ice cube and ice sphere. We placed them over two stands at room temperature. Which ice do you think would melt first?
The beauty of Thermal Conductivity
Wow! Congratulations!
We kept one ice cube on a Silver Bowl and one ice cube on a Steel bowl. Why did the ice cube on the Silver bowl melt faster? Physics will help!
Using Math to predict orientation of bottle caps
Wow! Congratulations!
We threw 600 caps on the floor. Can you predict their orientation?
Can you use Geometry to help this insect?
Wow! Congratulations!
An insect wants to catch a prey. Can you help the insect find the shortest path?
Can solids apply a buoyant force?
Wow! Congratulations!
We have learned in Physics that liquids apply a buoyant force. But, can solids apply a buoyant force as well?

The questions on your mind.
Open Door started in 2013. Today, we offer programs like Thinking Assessments, Thinking Classroom, the Subject Mastery Program for teachers, and a Critical Thinking Program for students.
We imagine a world where every child learns by thinking—not by memorizing. Our programs have "beautiful questions" to make children think and question, helping them build lifelong understanding of Science and Math.
A team of young graduates from top Indian universities (like IITs and NITs) designs the questions. These questions are making 300000+ students think more than before.
Open Door offers 4 main educational programs:
Thinking Assessments
For Classes 3–10: Topic-based tests with thought-provoking questions to build lifelong Science/Math understanding.
Thinking Classroom
For Classes 4–10: CBSE-aligned workbooks that replace traditional teaching with real-world questions.
Critical Thinking Program
For Classes 6–8: Developed with IIT Gandhinagar to help teachers guide students' critical thinking.
Subject Mastery Program
For Teachers: Helps Science/Math teachers master their subjects through assessment and improvement.
These are topic-wise assessments for classes 3–10. In therse assessments there are thought-provoking questions to help students deeply understand Science and Math.
For classes 4–10, it provides CBSE-mapped workbooks that replace boring lectures. Students tackle real-world questions like "Can you design Virat Kohli’s diet?" or "Would we hear ourselves if we shouted on the Moon?"
This program is designed with IIT Gandhinagar for classes 6–8. Its purpose is to help teachers guide students to think critically during regular school hours.
This program helps Science/Math teachers master their subjects. It allows schools to assess teachers’ knowledge and improve it in just 4 months.
Schools can explore Thinking Assessments, Thinking Classroom, or the Critical Thinking Program. To start, simply fill the contact form on the website, and we’ll call you!
Thinking Assessments: CBSE/ICSE
Thinking Classroom: CBSE
Critical Thinking Program: Works with any curriculum
