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.

This summer, keep your children engaged as they perform hands-on experiments and explore science concepts from the comfort of your home. As the world locks down – unprecedented in living memory – and children as well as parents are forced to stay indoors, what better than to get into the thick of things and learn some science in the bargain? While the world pins its hopes on its scientists to come up with a solution to the present crisis, you can do your bit by inculcating a sound scientific temper among the next generation. Come, join us for a summer of hands-on fun-filled science activities, conducted fully from the safety of your home!

About “unLAB"

We have researched and developed the “Tactile Activities” (TACtivities) that have been used and loved by more than 1 lakh students across the country as a part of their classroom curriculum. We provide unprocessed material in raw form to children. Children make before they start playing with the science models and experiments. Having made the TACtivities from scratch with their own hands, children develop a sense of ownership and feel empowered to make the models again. Most often, as children make and explore these TACtivities further, they tend to change a few variables (which may or may not have a functional impact), either consciously or subconsciously. This leads to exploration and learning, which happen in an organic manner, for each child.

Children are encouraged to make suggested variations, as well as innovations they come up with, and fill in an observation sheet to record their findings. A one-on-one discussion with a ThinkTac facilitator is then available, to guide the child through a path of self-discovery, connecting the dots to theory, reinforcing concepts and providing both anecdotes and real-life examples connected to the TACtivity and the underlying concept(s).

You may choose from a host of programmes we have on offer: CBSE and ICSE curriculum-aligned TACtivities for standards III-X, as well as a host of Theme-based programmes. You may choose 4, 6 or 10-TACtivity packages for your child. Look at our comprehensive list of Summer Offerings, and Sign Up Now!

ThinkTac Pedagogy

ThinkTac follows the four stages of Kolb’s experiential learning model, delivering deep conceptual clarity and cognitive skills.

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 www.tactivity.in, www.youtube.com/thinktac and www.diksha.gov.in.

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.
