It's that time of the year again, Lakshmi Girls Hindu College hosted its annual Science Fair and if you're curious about the effectiveness of paw-paw leaves in the treatment of dengue, the results of one investigation may interest you.
Transcript
00:00The school's auditorium is abuzz with the Lakshmi Girls Hindu College's annual science fair.
00:07Jaya and Chelsea are back this year, back from the future that is, to help us with our high fuel bills and global warming.
00:16So we have one major, major problem happening in the environment today and that is global warming, right?
00:21So global warming basically happens when we have greenhouse gas emitted into the environment and carbon emissions, right?
00:27So carbon emissions happen due to human activity mainly.
00:32After all, Jaya says, magnets are so underrated.
00:36We decided through voltage or through high cold conditions, you can create a stable magnet.
00:43So using the voltage or the motor, we are able to magnetize the magnets underneath the board to create a sort of hover or levitation.
00:50So when it's powered on, it should in theory create a levitation or force that would lift the board up and move it forward.
00:58Supervising the day's proceedings, Ms. Chandra Balroop explains this year's theme is tied to the school's 60th anniversary.
01:06We have been discussing our own school's evolution and our development.
01:11So that lent to us deciding on our theme, which is the evolution of technology.
01:17So we call it Evotech 60.
01:19So our girls are placed in three main categories.
01:22That will be the creative category, the investigative category and the innovation category.
01:28Form 4 student Anuradha sought to look into the evolution of the cotton gin, which was invented to separate cotton.
01:36Compared to 100 people working in it on a day, this can get done in an hour.
01:43In Trinidad, we do have a textile mill.
01:47But due to arising issues in the industry, it has been closed down, unfortunately.
01:54But if you do go presently, you will see these machines still in the mill.
02:02And you may want to take out your phone to take a picture of the event.
02:07And that's where Volasca and Soleil come in.
02:10This phone was created in 1973 by Dr. Martin Cooper.
02:14And it developed in 2006 when the actual first smartphone came out.
02:18And it still develops to this day.
02:20It teaches us the history of when phones were created.
02:24And I mean, now we have the Samsung and iPhones.
02:27And we just see it as a regular phone.
02:30But it's actually good to know the history.
02:32Because, I mean, these phones weren't just created the other day.
02:35They actually took time and thought.
02:38Sanvi, Aruna, and Veda demonstrate how water can be filtered and reused.
02:44It basically takes that used washing machine water or that sink water.
02:48And it stores it in a little tank, which uses a solar-powered base pump
02:53to pump it through some filtration layers.
02:56And then it will fall all the way down to the underneath,
02:59which has a secondary pump to pump it back up to water your plants.
03:04But if you're looking for creativity,
03:06these sixth formers show how easy, practical, and sustainable paper gardening can be.
03:13We took used paper and we recycled it and incorporated seeds into it
03:17to create seed paper, right?
03:19And that could be used as like food wrapping.
03:25It could be used for writing, anything really.
03:28And the good thing about this is that it's biodegradable.
03:30It's soluble.
03:32And when you want to dispose of it, you just need to lay it in the soil,
03:37dampen it, and the seeds will sprout.
03:40Store it in cool, dry areas to prevent germination before time.
03:44And then again, we would like to add multiple seeds to each sheet of paper
03:49to increase the chances of one germinating
03:51because it's not guaranteed that a seed can germinate.
03:56Down with dengue fever and unsure of what treatment to take,
04:00this trio investigated the effectiveness of ivy versus purple leaves
04:05by doing a survey of infected persons, their treatment options, and results.
04:11We found that most of them improved, the greatest amount improved,
04:15by using a combination of them both.
04:17So as you can see from here, those that took ivy fluids,
04:21it just helped with the rehydration, and they recovered from this very quickly,
04:25while they only had a moderate improvement in the platelet count.
04:28And those who took the purple leaf extract,
04:31while they took a longer while to recover from the dehydration,
04:34their platelet count increased greatly.
04:36Our conclusion is that the results from this study suggest
04:39that while purple leaf extract shows promise in improving platelet count,
04:43it may not completely replace the use of ivy fluids,
04:46especially in cases of severe dehydration.
04:48And a combination of both treatments may be beneficial
04:51depending on the severity of the symptoms.
04:53Jaya shares her recipe for the purple extract.
04:57I got a big pot of water and basically boiled the papaya leaf
05:02until it boiled and until it got that color, the yellow color,
05:06and obviously papaya have a very bitter taste to it,
05:11so I put black gravel sugar, a very good amount of sugar.
05:15Not exactly diabetes friendly, but their work left even parents impressed.
05:22It's very innovative.
05:23The children have used a lot of technology,
05:25modern technology now to bring out their ideas.
05:28It's very impressive.
05:30And they were very informative, all of them.
05:33You know, they weren't shy to actually let you know what they did
05:39and how it works, all that has props.
05:42It really, really was really informative.
05:4590% of the school population tuned out for the 2024 Science Fair,
05:51which saw the participation of some 200 students.
