Celebrating National Science Day

National  Science Day created a flurry of activity in Rollakal School! It is celebrated to mark the discovery of the Raman Effect by renowned physicist, Sir C.V. Raman. The Science teachers started the day with a commemorative ceremony, speaking about his work , especially the Raman Effect.

Students worked hard on preparing Science experiments and exhibits and proudly demonstrated their scientific knowledge. The Science teachers conducted a Quiz competition which drew great enthusiasm from the students. It was great to see them thoughtfully responding to the questions and having fun!

Overall, it was a day to understand the vital role played by Science and Technology in our lives, its importance in education and what is required to bring about innovative solutions to everyday issues, by harnessing the power of Science.

Cooking up Solutions!

The innovation bubbling away in RDF schools blows us away and we can’t help but share, with pride, the effort being made by these children to give their all to their education. Innovations in Science is an area that our kids are doing well in. On theoccasion of National Science Day, Class 8 students from Redlawada School create a Solar Rice Cooker from scratch and using only waste and recycled material!

They recycled waste material such as discarded wood panel, a spare tiffin box and silver paper. The tiffin box was painted black to create more heat. A simple device like this is very useful for rural people as it’s simple to put together and low cost. It doesn’t require power and by just placing it in sunlight, it can cook the rice, while going about their daily work.

Rooted in their reality, this is precisely the kind of innovation that is need to bring real solutions to rural people. We are so proud that our students think about the problems being faced by their communities and look for ways to help them. It also builds their scientific enquiry and temperament, helping them focus on design thinking and being creative.

Here’s to Healthy Living!

Mounisha (L), explaining the theory of natural and healthy living

Mounisha, a 2nd Year BPC student at the RDF VAPV Junior College, has been providing nutritional coaching to her friends, after learning about harmful chemical additives in fruit. A Chemistry lesson on how chemicals impact the nature of fruits and soil, in turn harming our health and Iives had a profound impact on her. She says, “My teacher explained about the number of chemical being used in growing vegetables and fruits – that the fruits, vegetables and chicken are contaminated. I was concered about this and explained to my friends how eating such produce impacts our health and our future negatively. I took my friends to the Chemistry lab and explained this to them in a practical way.”

“I came up with a list of ‘Do’s and Don’ts for my friends and the community, which are” –

 Don’t:

  • Don’t drink cold drinks. It pollutes our bodies and the environment
  • Don’t eat fruits and vegetables sprayed with chemical fertilizers, pesticides etc.
  • Don’t eat boiler chicken

Do’s:

  • Drink coconut water
  • Eat naturally grown fruits and vegetables, that have been grown without use of chemicals
  • Cook vegetables using natural ingredients
  • Eat free roaming, natural country chicken (Natu Kodi)

The practical lesson!

Mounisha’s friends took her message to heart and have agreed to spread this awareness in their communities about eating natural foods and avoiding the use and consumption of produce grown with chemicals. We are very proud to see Mounisha making an empowered decision not just for her health, but those of her friends, their families and the extended community too! We hope that her concern and practical solutions find its way into many homes, enabling them to make healthier choices and lead healthier lives.

More than a breath of fresh air!

Summer is in full swing and the heat gets to everyone – young and old. Areas where RDF schools are located are some of the hottest in Telangana. Air conditioning is simply not an option for people living in rural areas, but everyone has an intense desire to have access to cooling.

Students, assembling the materials & taking stock

However, Lady Luck was on our side! Synchrony Financial, a multinational organisation that has been supporting RDF in areas such as English development, Computer skills enhancement, soft skills and job skills training, on site in Kalleda School as well in their Hyderabad Head Office decided to recruit students of Classes 8 & 9 from Kalleda School to develop a clever cooling system that does not need electricity! The icing on the cake was that this cooler can be built from common waste materials such as empty plastic cold drink bottles – talk about being environmentally friendly and recycling plastic!

Hard at work, assembling the Eco Coolers

In just 3 months, Synchrony Financial and the Kalleda School students prepared smart, powerless air conditioners called ‘Eco Coolers’. The  method to make an Eco Cooler is fairly simple.  A board is cut to fit the desired window size and bottle neck sized holes are cut out in a grid pattern on the body of the plastic bottle. The neck of the plastic bottle is cut off and discarded, leaving funnel shaped bottle necks that are placed on the grid.  The Eco Cooler is fit into the window. When mounted, the wider port of the bottle faces outward and catches the passing wind, literally funnelling cool air into the house. It has the ability to bring the temperature down by as much as 5 degrees celcius!

..And they’re ready!

This was an electrifying project (pun unintended) for our students who were able to enhance their thinking and creative capacities and learnt how to make an innovative system, perfect for summer and taking into consideration the financial constraints of rural communities. In addition, it was an excellent enterprise in recycling waste materials and doing something positive for their community and the country too. This was such an enriching experience for everyone involved! While initially, students had to spend some time collecting the bottles and understanding how to make them, they slowly picked up and were able to make several of them!

We are so blessed that Synchrony Financial gave our students the opportunity to create a locally produced system and providing them with the necessary skills that empowered them to do something so productive for themselves and rural people. We are very grateful to the team at Synchrony Financial and so proud of our students’ new skills in innovation and social responsibility!

Inspired Student!

Raju of RDF Redlawada School is on cloud nine on receiving news that his Science project has been selected as the best project in the State level INSPIRE programme – and so are we! Coming from very simple and humble backgrounds, we completely understand the challenges faced by our children to progress academically; therefore their achievements are a testament to their grit and fighting spirit and makes us doubly proud!

A student of Class 10, Raju has been inspired by the teaching methodology and experimentation that is encouraged by his Science teacher and the supportive environment in the school which ultimately led to the creation of his prize winning project.

 The process started when Raju started thinking of greener and more economical ways to cook food at home and the production of Biogas. After a few days of experimentation and talking to his teachers, he came up with a plan. He collected some buckets of cow dung in a drum and sealed it airtight for 15 days. Then he poured water into the drum which changed the composition and created an organic substance, suitable for generating biogas. A metal pipe was attached between the drum and a stove to provide gas for cooking!

It’s heartening to see how students like Raju reflect on the real challenges of rural people and come up with innovative ways to provide solutions. While we fully support their aspirations to move to bigger cities to pursue their dreams, we are equally proud when they use their education and knowledge for the betterment of rural communities!

Well done Raju – we hope you continue to shine and grow wherever you go!

Scientific Creativity on Fire!

It all starts with an idea!

RDF is always encouraging its students to dive deep into a particular theme, topic or subject through interesting activities. Science is a subject that comes alive through the practical demonstration of experiments that can explain concepts easily. Our teachers also go through extensive training in order to teach their subjects better and help ignite children’s imagination.

Fine tuning with the Science teacher

Success!

This is precisely what was created in Kalleda School during a Science lesson recently. M. Yashwanth of Class 8 and M. Rajender of Class 9, with the help of their Science teacher, came up with the idea of preparing liquefied petroleum gas by mixing fire and petrol through a scientific contraption. This concept is used routinely in small and large scale industries, however our students were able to innovate and create a very low cost working model using plastic bottles, pipes, a air pump and a burner! The model was successful and was exhibited at the District Level Science exhibition. The experiment was praised by everyone and got 1st place and was selected to be shown at the State Level exhibition. While they didn’t win at the State Level, this encourage and inspiration they receive in school helps boost their confidence and also get them fired up to continue engaging in scientific experiments.

District Level triumph!

We have seen that providing children with a hands-on, learning environment really enhances their interest and curiosity in a subject, which then deepens their understanding, leading to further inventiveness. This is what we strive for – happy and creative children – letting their imagination soar!

 

‘Foam’enting Inventiveness

How many of us remember Science classes, trying to understand Physics, Chemistry or Biology only through theory and trying to grasp these theories with just our minds? But take the same concepts into the realm of experiments and suddenly complex theories become so clear and simple to understand!

Science needs hands on learning. It is to this end that a ton of effort is put into teacher training in our schools so that teachers understand new concepts and ideas to make their subjects interesting, to enable child to learn in interesting ways, thus retaining the learning. Once a concept is grasped, ideas and creativity to understand a concept better keep mushrooming! We have seen this time and again with our students.

In Kalleda School, students and teachers turned their attention to soaps- how they are formulated, what makes them pure or impure. Through a series of demonstrations, the Chemistry teacher made the students observe the foaming capacity of soap samples that were purchased from the market.

They were able to grasp how the purity of soaps is related to its foaming capacity. Through this experiment, they were able to clearly understand how soaps are made, understand their quality and differentiate between various soap formulations. Coming away with new knowledge and a greater understanding of stuff we use on a daily basis is the kind of positive impact we hope to nuture in every RDF student.

Now, at some stage, we are sure we will see some innovation related to soaps coming from the imaginative minds of our students!
