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.

About ThinkTac

ThinkTac is a social enterprise offering curriculum aligned, hands-on, experiential science programmes, face-to-face & online, providing materials & resources to create, experiment, tinker, innovate and learn science, inculcating scientific temper & improving cognitive skills. ThinkTac offers extensive digital content ensuring deep conceptual understanding while children have fun and engage with science. Programmes cover Physics, Chemistry and Biology for I – X Standards across CBSE, ICSE and several state boards.

ThinkTac currently works with over 35,000 children across schools in Karnataka, Tamil Nadu, Gujarat, Goa and Maharashtra. Some of India’s premier schools including the Valley School (KFI), Ekya Schools, Shiv Nadar Schools, Sishu Griha and the Delhi Public School have incorporated our programme into their pedagogy.

The activities, addressing specific concepts, are designed using simple, generally repurposed material. Each child makes 10-54 working models and experiments in an academic year, with each session lasting about 90 minutes. The child continues the exploration by making observations and building variations that are leveraged to achieve a deep conceptual understanding. The material selection and processes are designed to improve hand skills in the 5-9 year age-group and develop problem solving and creative thinking in older children.

The programme is supported by comprehensive content that includes printed guides, worksheets, making videos, digital manipulatives* and concept specific resources. ThinkTac offers extensive support for the implementation by school teachers including training, lesson plans and associated content like ice breakers and connecting the dots. A selection of the content can be seen at, and

Teacher empowerment is central to the ThinkTac programme delivery. The empowerment commences with a structured training programme, followed by personalised support and mentorship from a virtual coach. Technology and extensive digital content ensure effective preparation before a session. Back-office processing of the worksheets sheets offers actionable analytics and individualised remedial support to teachers. Content co-creation, showcasing opportunities and recognition motivates teachers.

ThinkTac has been recognised by the Government of Karnataka amongst the top 100 innovative start-ups. We work closely with several partners including the RRI Trust (founded by Sir C.V.Raman) on various outreach initiatives like the Raman Young Science Innovator Award that has seen over 13,000 participants registering for the 2019 edition.
