What happens in the 45 minutes
A real class. Not a sales pitch.
Your child does what they would do in the course. You watch the teaching for yourself, then decide.
- 01
Meet a real scientist
Your child joins a small live group of children their own age, led by an astrophysicist or engineer.
- 02
Work through one real idea
One idea from the course, explained properly, with your child answering questions out loud.
- 03
Try it with their own hands
A short hands-on exercise, so the idea is something they did, not just something they watched.
- 04
You decide afterwards
We send you the syllabus after the class. If the fit is wrong, we will say so.

What parents say
From parents. In their own words.
The Aeronautics course has been excellent for [my son] and I can already see the difference in his conversations among his friends. I am definitely signing up for the next course.
[She] loved the class and we would be signing up for the Nov batch. We loved Purva the teacher who understands how to handle a child and introduce her to such advance topics.
We already signed up for the next course as we had a great experience in the earlier one and would want to continue this wonderful engagement.
My son took a class with WhyCosmos and it was one of the best things ever. I have never seen him so excited about space or rocket ships.

Questions parents ask
Before you book.
Is the class really free?
Yes. We do not ask for payment details, and there is no obligation to enrol afterwards.
Does my child need to know anything about space?
No. The class starts from what children already wonder about. No prior knowledge is needed.
Can I sit in on the class?
Yes. Parents are welcome to sit in from the same screen and watch how the teacher works with the group.
My child is shy. Will they be left out?
Groups are small and the teacher asks each child by name, so quieter children get their turn too.
What does my child need for the class?
A laptop or tablet with a webcam and microphone, an internet connection of at least 10 Mbps, and a recent version of Chrome, Firefox or Safari. Headphones are optional.
Is it safe for my child?
Classes run in a secure virtual classroom, and WhyCosmos complies with India's Digital Personal Data Protection Act, 2023. We never use a child's image or work without your explicit consent.
What happens after the free class?
We send you the syllabus. If you want to continue, you pick a batch and enrol online. If the course is not the right fit for your child, we will tell you.
