Thanks a lot to the ThinkTac team for the wonderful and inspiring course. My kids have started thinking and doing newer experiments on their own!

I would like to thank ThinkTac for putting the thinking hat in my son's mind. As exciting as the experiments are, the interactive class sessions held by Vishal sir and the team are equally engaging. The teachers are very helpful and innovative in suggesting alternative materials during the lockdown stage. You really inspire a student to think with a scientist's mindset with your suggested variations in the experiments. The observation table, recording, followup are very systematic.

My two children, aged 8 years and 6 years, attended the Kitchen Chemistry unLab programme. Our home instantly became a laboratory of exploration for the next few days! The kids discovered how simple, everyday items in the house, and especially items used for cooking, can be used to explore acid-base chemistry. The experiments were holistic in nature, allowing my children to explore questions in biology (how are baking soda and yeast similar?), physics (what are atoms and molecules? How do batteries work?), maths (how do I measure/alter the ratios of the materials being mixed?) and so much more! Learning science in this way helped them see how everything is inter-related and they really enjoyed the programme. Needless to say, as an adult and physicist myself, I learnt a lot too! We look forward to attending many more such workshops, curated and led by the excellent team at ThinkTac.

Thank you to all the teachers of unlab for providing such a wonderful journey. It was such a nice experience to be a part of it and kudos to your thought process of seeing every child as a child and not a diagnosis. I think I came more near to my creative side than before. Tactivities are a perfect example of "learn with fun" concept. I never knew that experiments could be this much fun too. It kept me engrossed the whole day, and I was like so eager to know the possibilities of different outcomes. All thanks to you. Thank you very much...

I enjoyed all the unlab workshop that I attended. The experiment which I enjoyed the most are Fire Extinguisher, DIY Base, Acid & Bases, Parachute, Catapult. Apart from enjoying the experiements, I also learnt to predict the outcome and compare the actual results. These experiements helped me to understand how things work.


Participant of unLab

Our son (Shoubhik) enjoyed all the sessions and used to eagerly wait for the sessions. These sessions helped him to observe and analyze the outcome. Though it was online classes, Teachers took extra effort to guide the kids. Teachers focussed on simple concepts and explanations which kids can related and enjoy. Looking forward for unlab to expand their reach to many more kids. Quite a noble effort from the ThinkTac Leadership to bring such activites during lockdown period. Wishing that such activites continue to happen in future.

About unLab

The ThinkTac pedagogy has been developed over the last 5 years and used by over 50,000 students who have experienced over half a million activities hands-on. 

unLab is ThinkTac’s Science as a Service platform that delivers exceptional conceptual clarity and cognitive skill development with the learner having fun all through the process, all from the comfort of your home. 

unLab follows a Kolb’s Experiential Learning Pedagogy: Concrete Experience commences with hands-on activities using simple materials followed by Reflective Observation using observation sheets, facilitated by a ThinkTac Educator in Guided Tracks. Children are provided a scaffold for active experimentation with variation and innovation pathways culminating in showcasing opportunities.

Different elements of the process described below are enabled, based on your subscription plan.

Cohorts - Learning Together

We believe that learning is a team-sport and a learner is always part of an age group based cohort where making, exploration and learning happens together. On signing up, each learner is assigned a cohort that is based on the programme and the board and standard in which the learner is studying. Further, to the extent possible, children who are following the same academic calendar will be together in a cohort.

Once you get your access credentials, you can immediately start making the 10 TACtivities that you will get instant access to.

Make - TACtivities with Simple Materials

unLab activities are specially designed to be made with simple, unprocessed materials and many of them can be entirely made with household materials. The use of these simple materials encourages the learner to experiment with different ideas and innovate along the way. 


Collect the material needed and understand the process by reviewing the DIY guides and videos. Reach out to us on Forums or WhatsApp if you don’t find a material you need and we will suggest alternatives.

Make, Play, Observe & Share

Make the TACtivity referring to the steps prescribed. Make it a family event. Cut, tie, snip, pierce, glue and make your activity. Ask on the forum or reach out to us in case you need any clarifications. You will need to keep common measuring instruments like a kitchen weighing scale, protractor etc., that are needed for the observations, handy.

Share your completed TACtivity and innovations with your cohort and learn from what they have done. Participate in contests and have fun with your TACtivities.

Guided Track - Learning Expanded

Make TACtivities a habit and don’t miss the fun each week, under the motivating influence of our Educators. Children who are eligible will be automatically enrolled to a guided track each week / fortnight depending on their subscription. You and your Cohort will first make and submit photos of your TACtivity and the observation tables.

Guided Making

Guided making following the same process of making described above, with hand-holding from your ThinkTac educator. Once completed, upload a photo of your TACtivity and the Observation to get personal feedback.

Guided Learning and Innovation

A weekly scheduled Group Discussion is a key learning opportunity, when our educator will help you understand the key concepts behind your TACtivity. Get your questions answered and learn what more you can do. In case you miss a session, you can always watch a recorded video of the discussion.

If you are in the innovation plan, make variations, explore them and make additional observations. Get feedback from your Educator and find ways to explore further. Access additional resources and teach your friends a thing or two on the topic.
