Spotlight on a Young Scientist: Deepika Kurup

Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.



Name: Deepika Kurup

Home: New Hampshire, USA

Age Category: 16-18

Project title: Solar powered silver combating bacteria in drinking water




During her family summer visits to India, Deepika was troubled to see small children drinking polluted water from streams. She wondered how developing countries could best clean their water, and once returning to the U.S. tested different chemicals. She found that a solution mixed with silver and powered by the sun removed bacteria faster than current methods. With this finding, she hopes to provide cleaner drinking water to families in India and around the world. 

What was the inspiration behind your project? 

Every summer my family and I travel across the world to visit India. In America, I always had the privilege of having unlimited access to potable water; however, in India I saw children drink water that I felt was too dirty to touch. I wanted to find out why these people lacked access to safe water, a substance that’s essential for life. I learned that we’re facing a global water crisis. According to the World Health Organization, one-ninth of the global population lacks access to clean water. This unacceptable social injustice compelled me to find a solution to the world’s clean water problem.

When and why did you become interested in science? 

I’ve always been curious about the world around me. When I was younger, I’d constantly ask my parents questions about how the world works, and their explanations were often rooted in scientific concepts. As I grew, I began to notice that science is truly everywhere. After hearing about scientific discoveries on the news and reading stories of famous scientists in the past, I realized that science has the power to lead us to revolutionary new discoveries that can change the world. This passion for science, combined with my interest in solving global challenges, is what sparked my interest in research.

What words of advice would you share with other young scientists? 

I would strongly encourage other young scientists to continue to pursue their passions in science, technology, engineering and math. While scientific advancements are being made every day, our world still faces several grand challenges. We need young scientists to solve these grand challenges, as science has the power to help people find solutions to problems we never thought could be solved.

Head back to school with new features in Google Classroom

Posted by Will Phan, Google Classroom Software Engineer

As you gear up for the new school year, try the newest features in Google Classroom for more ways to save time, engage your students and keep everyone organized. Most of these features are rolling out this week; stay tuned in the next few weeks for more back-to-school goodies in Google Classroom, Google Docs, Sheets and Slides, all designed to help you make this school year yours.

Keep students engaged with question-driven discussions 

Since Classroom launched last year, teachers have been using their class stream to host student debates, Q&A and discussions. Starting today, you’ll be able to do this in a more collaborative way. You can post questions to your class and allow students to have discussions by responding to each other’s answers (or not, depending on the setting you choose). For example, you could post a video and ask students to answer a question about it, or post an article and ask them to write a paragraph in response.

“Often, teachers want to do a quick check-in on what their students are learning. Now with this built in to Google Classroom, teachers can easily do this on the fly, any time,” said Michael Fricano II, who teaches at Iolani School in Honolulu. “Your class can have a really engaging, focused conversation.”

Reuse posts 

You know those lessons that worked so well last year that you want to use them again? Now you can reuse assignments, announcements or questions from any one of your classes — or any class you co-teach, whether it’s from last year or last week. Once you choose what you’d like to copy, you’ll also be able to make changes before you post or assign it.

“The reuse post feature gives teachers the gift of time. Making changes to something already created is way easier than starting from scratch,” said Heather Breedlove, Technology Integration Coordinator at Flagstaff Unified School District in Arizona. “It’s working smarter, not harder.”


Calendar Integration 

In the next month, Classroom will automatically create a calendar for each of your classes in Google Calendar. All assignments with a due date will be automatically added to your class calendar and kept up to date. You’ll be able to view your calendar from within Classroom or on Google Calendar, where you can manually add class events like field trips or guest speakers.



And a few more improvements you’ve asked for:

  • Bump a post: When you want to make sure an older item is easy for students to find, you can now move any post to the top of the stream. 
  • Due dates optional: For long-term projects or student-driven assignments, you’ll now have the option to create assignments that don’t have due dates. 
  • Attach a Google Form to a post: Many teachers have been using Google Forms as an easy way to assign a test, quiz or survey to the class. Coming in the next few weeks, teachers and students will soon be able to attach Google Forms from Drive to posts and assignments, and get a link in Classroom to easily view the answers. 

    In case you missed it 

    We know YouTube is an important source of educational content for many schools. Because it also contains content that an organization or school might not consider acceptable, last month we launched advanced YouTube settings for all Google Apps domains as an Additional Service. These settings give Apps admins the ability to restrict the YouTube videos viewable for signed-in users, as well as signed-out users on networks managed by the admin. Learn more here.

    All of us on the Classroom team have been deeply touched by the teachers in our lives, who inspire us in the work that we do. For me, that’s my brother Tuan, an English teacher at the Chinese International School in Hong Kong. We make these products for you. And we hope these new features will help you kick off another incredible year of teaching and learning.

    Spotlight on a Young Scientist: Zhilin Wang

    Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.


    Name: Zhilin Wang

    Home: Singapore

    Age Category: 16-18

    Project title: Zinc air batteries for affordable, renewable energy storage 


    Zhilin has used his large capacity for wonder to question everything since he was a young boy. This strong curiosity for not just what goes on around him but what happens in other countries led him to understand how developing countries access renewable energy. To speed up the slow chemical reaction produced by oxidizing zinc with oxygen from the air, Zhilin built an aerogel consisting of carbon nanotubes and graphene. His gel sped up the oxidation process, allowing faster storage of renewable energy. He looks forward to testing his aerogel in villages that don’t have electricity – rather than the multiple sources we rely on today. This system, with a little more development, could have expansive use in areas ranging from wearable computing to location-based applications, where an instant and accurate indoor 3D positioning system is in high demand.

    What was the inspiration behind your project? 

    Looking at the world around me, I can’t help but marvel at how far our search for novel materials has come to improve our everyday living. Nowadays, such materials are literally everywhere: in our smartphones, our clothes and even, for some of us, our bodies. Once in a while, when I find out about a novel material, I get really excited and dream about how it might shape our future.

    Graphene aerogel is one such material. Think about this: you have a solution of graphene and a solvent, say water. If you can remove the solvent to leave behind only the graphene framework (or more illustratively, a graphene skeleton), you have yourself a graphene aerogel with some curious characteristics. It is super conductive, ultralight – reaching below the density of atmospheric air in some samples – and has a contact surface area matched by few. This means that it can potentially make astounding improvements in many of the things we use on a daily basis. I was eager to see if it can be applied to something that it had never been tested on before. So when a need for improving the efficiency of batteries came my way, I thought, “why not use graphene aerogel?”

    With a stroke of luck, the graphene aerogel turned out to be suitable for the battery. Yet, I didn’t want to end my project there; I wanted to see if the improved battery could directly impact the lives of people. Having reflected upon some of the things I was grateful for, I realized that one of the most wonderful gifts I have received is a quality education. Without it, I wouldn’t have been able to read my favorite books, learn so much about the world or even participate in this competition. Yet, many in underdeveloped regions do not receive basic education. Despite the promotion of global education, a great deal of children are forced out of school to support their families by working on farms or in factories. The only time they could spare for education is in the evenings but even then, the scarcity of reliable lighting means they’re unable to learn in the dark, as much as they want to. Can my battery be used to light up their nights? I didn’t know for sure, so I tried to find out.

    When and why did you become interested in science? 

    My love for science started around the time I was in primary school, when I found myself so curious about everything around me. You can say that every opportunity for me to discover something new was as irresistible as a candy laid before me. Of the many things I wanted to know, scientific demonstrations particularly piqued my interest. They seemed almost magical – water instantly freezing on a hard knock, violent fountains formed from Coca Cola and mints. But I wasn’t satisfied with merely marveling at them. I wanted to appreciate their inner beauty and understand how they actually worked. For me, science is about having a passion for the beauty of the world around us and understanding how and why things happen in it. Isn’t that much more interesting than simply accepting things as they are?

    What words of advice would you share with other young scientists? 

    Never be afraid to ask questions concerning things you are curious about, for what lies ahead is either a path of discovery or at least the joy of learning something new.
