Today is our last day here. And apparently there's a bandh going on. Ummm...I really hope that doesn't mean school is canceled and we don't get to do all our experiments. If the TRS (Telangana Rasthra Samithi), the party agitating for a separate Telangana, gets to the school before first period, it might be. Once school starts, though, the principal won't stop it again.
He has a good argument for the TRS too. Once the cooks start making lunch, it would be a huge waste of money and food to get rid of all they've cooked. And the TRS people around here seem to understand that the RDF is serious about teaching the kids, and that interrupting school is not the best way to advance Telangana's interests.
Just in case, though, we decide to teach the 6th graders first. They've been asking for us to come to their class for days, and we haven't yet done any experiments with them. It screws up the schedule a bit, but we really want to work with them.
I do the same magnetism spiel from two days ago, but simplify. I emphasize the attraction/repulsion a bit more since they haven't really learned it yet. I have each person in the group try to push like poles of the bar magnets together, and they giggle with glee as each successive person fails to touch the two ends. "Arey, adey kaduluthondi!" (Hey, it's moving by itself!)
My mom was planning to just show them electroplating, but she ends up doing it the same way she did it with the other classes, by assigning each student in the group to hold a wire or a coin, or to observe the coin and tell us when it has turned red enough to break the circuit. It gets them more involved, and they feel like science is something they can do, so that's okay.
For 4th period, we do both sections of 9th. We call them over to the lab and demonstrate the iodine clock. I pour everything in and tell them it's the pindi padhartham (iodine-starch test). Then I ask, why isn't it changing colors? About 20 seconds later, I draw their attention back to the tube, and they gasp as it suddenly begins to change to a dark blue. Now it's time to give a cut-down explanation of what's happening in the tube.
Afterwards, we give them a little demo of litmus paper as well, then eat lunch and carry all our solutions back up for the 7th graders. These kids are much more rowdy than the 6th graders. The teacher has brought all of them out here, and since we can only take half the class at any time, the other two groups are sitting by the wall in front of us. But they're so close, and they can't resist getting up and peering over the other kids' shoulders. No matter how many times we tell them they'll get their turn next, they keep sneaking up to look at the magnets and the litmus paper.
A couple of them even manage to knock over the (dilute) sodium hydroxide solution. Oops. Well, there's still a little left in the glass, but they have to be careful not to touch the tablecloth for now. Luckily, a later group knocks over the acid, so the tablecloth is neutralized and deemed safe once again.
By the time the last group comes up, they already know half of what I'm going to tell them because they've caught glimpses during each of the other 3 groups' turns before we chased them away again. It's okay, though, because it shows how interested they are. If I were a normal teacher and this were an everyday occurrence, it wouldn't work, but we're only here until this evening, so it's okay. At least they're paying close attention (and helping to clean up the iron filings they've spilled all over the place).
Okay kids, it's been fun, but we have to go know. Keep that curiosity burning! You guys are great.

Day 26 - Electroplating
Today is filled with electroplating. We're doing it for the 10th graders first, then 9th, and even 7th. Since we aren't explaining things in detail to the 7th graders, we're doing both sections (meaning about 60 kids) at once.
We call up the kids in groups so they can see the plating up close. We have them hold the coins and connect the wires as much as possible so they feel like they're actually doing something. As the one-rupee coin turns red, they laughed in astonishment. And then we switch the poles, and like magic (or chemistry), the color disappears.
Calling up 60 students in groups takes time, though, and by the time we finish, we're halfway into their break. Fortunately, the morning's rain has slowed the preparation of lunch, and break has technically not yet begun. Still, the younger kids in other classes are done, and they've begun gathering at the door.
We literally have to chase them away because they're distracting the students we're trying to teach right now.
"Go play," we tell them. "We'll come to your class too."
And still they hang around. A few days later, when we visit the 6th grade class with our copper plate and beaker of CuSO4, one of the kids excitedly tells the others, "Adi erraga avuthadi!" (It's going to turn red!)
We ask him, how do you know that? And he replies that when we were showing this to the 7th graders, he was listening through the window. Even after we shooed them away.
You've got to give these kids props for how much they want to learn.

Day 21 - The Last of the First
Today is my last full day at Matendla. We're going to do a couple labs, take care of the English classes, and say bye to the kids. Tomorrow morning, we'll catch the bus to Siddipet and then another bus from there to Jubilee Hills in Hyderabad, from where we will have to take an auto to get home.
We start in the morning with the 10th graders, doing that Bullseye lab (for projectile motion) that we did in Mr. Robinson's class in high school. Unfortunately, without a smooth, relatively frictionless ramp, the calculations don't quite work out. We turn it into a lesson on how science doesn't work a lot of the time, and how you can work backward from what you find to figure out why it didn't work. Well, at least the kids had fun playing with marbles.
The 8th graders have their turn with surface tension next. We only have a limited number of boats, so we pick popsicle sticks with their names. Some boats move successfully, while others don't. Perhaps a slightly less concentrated soap solution would work better next time.
Not everyone gets to try a boat, but still, they look pretty happy when the boats actually move. If nothing else, they're excited about the camera :D
After school is the last English class. The kids have been falling over Curious George, The Beauty and the Beast, Thumbelina, and Mickey and Friends like piranhas. As soon as the lesson is over and it's time for reading, there is a veritable riot as they scramble for the 15-20 books we have. There still aren't enough, so they read in groups. They're asking fewer questions of us, which I hope means they're understanding more words, but I still see some writing down words they don't know to look up later. That's the best way to do it!

Day 13 - Magnets
It's really difficult to make the iodine clock reaction work when you have no balances and therefore no idea what the molarity of your solutions really are. Magnets, on the other hand, work perfectly well without balances. Nik found some magnets and a little packet of iron filings before he left on Sunday, so we're going to do magnetism for the 8th and 9th graders since it's in their curriculum (though all the pictures here are of 8th).
The kids have divided into their groups, and I give each a little box with some iron filings spread out. After a little introduction to magnets (with the help of a compass), I hand each group a bar magnet, and have them play with getting a field pattern in the filings.
When I go around and tap the box as it rests atop the magnet, the filings fall into place and the kids eyes widen. "Look, it's making a pattern!"
Now to explain the why, and how the field goes from north to south in all directions and how we can find what the field looks like by looking at the pattern in the filings.
And now a little induced magnetism to end the lesson. Iron piece = not magnetic. Iron piece + magnet = magnetic. Take off the magnet, and the filings fall off the iron piece again. It's like mag(net)ic!

Day 12 - Resistors and Circuits
We tried a lot of stuff yesterday, including making a lemon battery and changing the color of a color-changing LED we found. Today, we played around a little with circuits and resistors today in the 10th grade science class.
We basically took a resistance box and had the kids pull out keys (therefore adding resistance) and put them back to see the effect on the intensity of the light bulb. We had a color-changing LED as well, but that burnt out in the beginning of the second class (the 10th class is divided into two sections). At least everybody got to see it once.
The girls are sitting on their side of the classroom, waiting patiently, but...
ZOOM! As soon as it's their turn, they're up like they've been stung by fire ants. It's good to see that enthusiasm.
And enthusiasm is certainly not lacking here. A couple days ago, some of the students came up to us as we were talking to the headmaster and asked if we would teach an English class. My mom agreed to take a class from 8:30-9:30 (the hour before school) and 5:30-6:30 (the hour after school), so I'll help her out with that a little bit. The class will be both sections of 10th, and 50+ students is a tad difficult for one teacher.
The 10th graders want a little more help because they need to take their 10th class exams at the end of the year, and as much as they say they like English, it's not their strong suit. Who can blame them? The school is Telugu medium as of now (meaning all the classes are taught in the medium of Telugu), and they are one English teacher short of a full teaching staff.

Storm
I look out my window and it looks like a storm is fast approaching. The farmers will certainly be happy, for their fields will finally get some water. Unfortunately, this means that the kids will not be here early tomorrow morning for the English class because they have to help their parents in the fields, but this is their livelihood, so it's okay. (Click any image for a high-res version).
The sky is absolutely stunning.
To the left, the clouds are white and the sky is bright. To the right, the dark mass of clouds moves in.
The sky is even darker now that we're in the thick of it. This is my absolute favorite picture of the lot.

The RDF School Matendla
Matendla Rural School is run by the Rural Development Foundation. The students are given a midday meal and their uniforms and school books are paid for by the RDF. The teachers are all local which means they are more invested in the students' learning and more motivated to actually be at school and teach every day. The students, in turn, are invested in the community. Many of them go home after school and help their parents in the fields or in taking care of the little ones.
Last year, the teachers, parents, and students together took some initiative in the village. The teachers began by stopping their alcohol and cigarette intake as completely as possible. Then they talked to the Village Committee and got the council leaders to stop as well. All told, they got at least 30 parents to stop smoking and drinking.
Another project the school stared relatively recently was that of a kids' bank. The students themselves take on the roles involved, and a teacher checks the numbers afterward. It helps the children learn how to use the banking system - and gets them interested in saving money.
Really, the students are involved in everything from their own learning (the Question Bank questions) to the running of the school. They have to participate in at least one extracurricular activity, and sports are highly encouraged. At least within Medak district, many top student athletes are from Matendla.
I played with them. They're not bad at basketball either despite the fact that their hoop has no special backboard and their court is a dirt courtyard.

Day 2 - Assembly
It's Monday morning, and we're up by 7 because we're supposed to have breakfast at 8. School starts at 9:30, but some of the students start showing up around 8:30. These are mainly the ones in charge of things like checking the library, cleaning their classroom, or writing the news on the big blackboards set against the walls outside (this particular one is actually for a "classroom" on the veranda).
At 9:30, the bell rings and the high school students gather in the courtyard for assembly. Nick, my mother, and I are called up to the stage to introduce ourselves and say what we'll be doing. The students, meanwhile, stand in front of us in long columns, one per class (grade). As usual in an Indian school, they begin with morning exercises, followed by Vande Mataram and Maa Telugu Thalliki (patriotic songs for the country and the state, respectively). On other days, they recite a prayer to Saraswathi, the goddess of education, or sing Saare Jahan Se Achcha. I'm cheating a little bit with this picture because it's actually from the next Sunday when the primary school kids joined the older students, but it'll give you an idea of what it's like.
A couple of students on stage read out the news, while those in the columns listen and then raise their hands to answer some related quiz questions. Next comes the Question Bank question, a "why?" or "how?" wondered at by a student, written down, and placed in a box near the library. Each day, the question is asked, and if none of the students know its explanation, the teachers provide the answer. Out of the questions in the box from Saturday, the teachers picked this (translated): "If we can't see or touch air, how did we ever find out what it's composed of?"
When we are done here, we are taken to the other side of the building to introduce ourselves at the end of the primary school assembly. Here, the stage is made of raised earth, and the Nursery (think preschool) through 5th graders are lined up in their own columns, standing remarkably (though of course not completely) still. I've yet to see that many five-year-olds with that much self-control anywhere in America. At the end, around 10 am, the students march off to class to the cadence of a snare drum and a very small bass drum. Left, right, left, right, though the student in front of you may be going right, left, right, left...

Accommodations
So as it turns out, I'm staying in the "science lab," which has had a couple beds added to it to turn it into a guest room (very fitting, no?). There's an attached bathroom, which suggests that the room's double role is built in. The room is to the right of the headmaster's tiny little office, which never needs to be locked.
There are posters hung all over the room illustrating science-related topics, with multiple more rolled up on the shelves. In the picture above, there's one about great Indian scientists, vegetative propagation, and mitosis. Meiosis is on the other side of the room, and the male and female reproductive systems (surprisingly) are hanging in one corner next behind the TV (which may or may not work though we don't plan to watch it either way).
The floor in one corner of the room sports a cement-and-paint map of India, though it seems somewhat out of place in the science room/guest room/English book library (the Telugu library is made up of two shelves like the one above in a room across the quad).
There are also science materials present, so I suppose it's fine. The school recently got a donation of some science materials from a vocational school in Siddipet, which are stored in the glass-windowed cabinet. Through the glass, we can see that the top shelf holds a variety of dry chemical bottles, the second (despite the cracked glass) dark-tinted liquid containers, the third a panoply of instrumentation (prisms, lenses, rheostat, voltmeters, bulbs, etc.) along with a human heart model, a sphygmomanometer (for blood pressure), and the fourth books and glassware.
Well, that's good. There's more equipment than I would have guessed, although some of the basics are missing. Elizabeth bought and brought a set of six 100 mL beakers with her since there were none here.
At any rate, the plan is that my mother will stay here the first night, meet the students, and return to Hyderabad by bus tomorrow. As it turns out, they'll ask her to stay and help teach English, so she'll be back here again Friday, but, shhh, my fellow time travelers, keep it quiet - we don't know that yet.

To the School
Okay, I'm going to start posting what I've been doing for the last two weeks. Since I haven't posted much detail yet, what I'm going to do is to pretend that today is the first day, and schedule a post every day in that way. So let's step in the time machine (oh, you don't have one handy? That's okay, I have an extra you can borrow) and journey back two weeks to our arrival at the school.
We rent a car and leave Secunderabad Sunday while the sun is just past the midway mark. A couple hours later, we arrive in Siddipet, the nearest big town to Matendla. Here, we stop for some chai or coffee and end up eating Gobi 65 and Veg Manchuria in a restaurant that, curiously, serves neither chai nor coffee. Then we meet up with Vishnu, the headmaster of the school, who joins us in the car and directs the driver (renting a car here means renting a driver as well) to the village. He also explains a little about the geography, history, and politics of the area, pointing out villages and landmarks on the way.
My first impression of Matendla is that I am very impressed. The school building is large and modern in style, painted a warm, welcoming (but not gaudy) orange. Since the whole landscape is greens, reds, browns, and oranges (hurray for the iron-rich soil of Andhra!), it fits right in. The courtyard is pretty, there are farms on all sides, and unlike any city school, there is space for the children to play.
Upon reaching our home for the next two weeks, we spend some time talking about how the school works, the guiding principles of the Rural Development Foundation, and the students. At the RDF School Matendla, they teach not only the subjects needed to pass the 10th class (grade) exams, but good values and life skills as well. They have little Aesop's Fable-like sayings painted on all the walls:
It's getting dark, and the others have arrived. There's a high school senior named Nikolaus from Austria who will be spending a week here helping out with English classes, and the volunteer coordinator Elizabeth has brought him up from Hyderabad. I show my plant pigment chromatography and DNA extraction lessons/protocols to the science teachers, and they decide that the material is 10th-grade level.
Soon afterward, we eat dinner and retire to our guest rooms. Unfortunately, the rains a few days past combined with the fluorescent lighting have brought in a storm of flying insects. Now is probably the time to mention that I really don't like bugs. Still, once I've climbed into the mosquito net and tucked it in securely, all is well. I feel safe enough inside to get a good 8 hours of sleep. In the morning, the students will come, so a little rest should be good.
