EXPERIMENTS ON PHOTOSYNTHESIS
Test tube and funnel experiment :

The test tube funnel experiment demonstrates that oxygen is evolved during photosynthesis. A few branches of Hydrilla are kept in a beaker containing pond water in which a small amount of sodium bicarbonate is dissolved. The branches are covered with a glass funnel and a test tube full of water is kept inverted over the stem of the funnel as shown in the figure. Now the apparatus is kept in sunlight for 4 to 6 hours. The gas bubbles may be observed from the ends of hydrilla branches kept within the glass funnel. These gas bubbles are collected in the test tube by the downward displacement of water. The gas is tested for oxygen. When a burnt splinter is taken near the mouth of the tube, it glows brightly and proves that the gas is oxygen.The test tube and funnel
experiment demonstrates that oxygen evolves during photosynthesis.

Prayaag Eduserv focuses to bring out educational digital contents in audio visual e-learning format, which is easy to understand and help the student remember as and when required. It relieves the student from cramming, memorizing the school text books.We thereby meet the unmet need of learning the school curriculum in multimedia format which makes the student motivated to learn deeper with ease, instead of learn by route.

Our ultimate vision is to trigger creative imagination of the students to learn the content with enthusiasm. With the above mission in mind, we ventured to create Audio Visual Content for Tamilnadu State Board +2 Science & Mathematics. Each subject is given with animations, graphics, images, videos to help the students understand in a simple way. Number of academic experts who are leaders in the respective subjects worked hours &hours with visual communication technology experts to bring about an excellent collaborativeproject of educational ecosystem to achieve the best exam results. The DVDs are easy to use and hence the students enjoy learning.

We have included Multiple Choice Questions (MCQ), Frequently Asked Questions (FAQ) plus solved Board Exam papers.

To start with, we brought out Physics, Chemistry, Biology &Maths for +2 Tamilnadu State Board Syllabus in English. Soon we will have Physics, Chemistry Biology &Maths for +2 TN State Board Tamil medium students, as well.

This long journey only just started. Our management is not only focused on the exam results but also on mind development of the students. As we progress we will bring out educational DVD's for +1 and 10th standard students for Tamilnadu State Board.The passion to benefit all the stakeholders including parents, students and teachers, driven us to center our attention on the art and the science of delivering client-delight.

The unique feature of our DVD content is our natural,easy to understand voiceover which reflects closely the contents as mentioned in the respective text books and also explains the visual images very clearly.
It is our endeavor and hope that all our efforts will help the students achieve their Educational Goal and also build job oriented career by preparing the students for engineering and other professional courses.
