The Adventures of a Science Teacher

Month: July 2022

Three More School Visits

Throughout our time in the program there were three more school visits. Each school was different than the one that preceded it.

Institución Educativa N°6152 Stella Maris

As we walked through the front gate the students were interested in us but there wasn’t the excitement that we had seen at the prior schools. We walked through one of the courtyards and entered the secondary section of the school grounds. As we walked by an 8th grade math classroom the school administrator asked for four volunteers to go into the room and I was one of them. The other teachers would go into different rooms. Once we entered the room the teacher stepped aside and we were left in the front and center of the room with no introduction. After a brief awkward pause we started a brief question and answer session until we were picked back up.

Students learning to weld. I was dismayed by the fact that not everyone was wearing a welding hood.

Next up was a walk over to the primary section of the grounds. While there we entered a classroom (3rd grade?) and did a little group activity with them.

For the last part of our visit we were brought into their English classroom and several of their students performed some folk dances for us. After some goodbyes we were on our way.

Our welcome to this school was completely different than the other schools we visited. Instead of seeing traditional dances, their orchestra performed for us in the main courtyard. This would set the tone for how different this school would be.

Once the students started to pack up their instruments and some introductions were made, we were brought into a math classroom. Every student had a brand new laptop and there was an interactive whiteboard in the front of the room. Of all the schools we visited, this one resembled schools in the United States the most. When we left the math room we were broken up into groups and brought into different rooms. My group was brought into a robotics lab where students were working on building remote control cars that would be programmed with an Arduino. Later in the year they would be building drones.

Some students had me help them with putting their car together

This school is a public school but students need to apply to get in. From what I understand, this school is also sponsored by an oil company and that explains why they have so much more in the way of resources than the other schools we saw. Prior to leaving the school some students gave brief presentations on some of the projects that they had worked on. Some students gave presentations on a tiny submersible that could be piloted remotely and was meant to collect garbage in the ocean. This was just a functional model but it was impressive. Another group gave a presentation on a disinfecting robot that they created.

This robot uses UV light to disinfect floors

One of the students gave a presentation on a voice assistant app he is creating for people who are visually impaired. The last group of students gave a presentation on their studies of electromagnetism, Faraday’s Law, and electromagnetic induction. The electrical grid is not very reliable and students want to look for ways that they can work towards improving it.

As we walked through the front gate there were students holding up a metal hoop covered in red, white, and blue balloons that they had us walk through. From there we were escorted to their auditorium for an assembly in our honor. We were seated on on side of the room, students on another, and some educators on a third. Students performed traditional dances, a student sang a song for us, and we were presented with certificates of appreciation.

The rest of our visit to this school was a whirlwind. We were broken up into small groups and went from classroom to classroom. In one classroom students performed a conversation in English that they had created. In another classroom we got to see some 1st graders learning to count using manipulatives like beer bottle and soda bottle caps. Another classroom gave us some arroz con leche and bracelets. In another classroom we joined the class in drawing our three favorite things in Peru. While this was all taking place other students were playing in the courtyard. In between rooms students would come up to us and ask for the occasional autograph or selfie.

For the first time I got to go into an actual science lab although no students were currently in it. There were long lab tables covered in porcelain tiles with science supplies lining some of the walls. One of the things that I found interesting was that they had preserved specimens of some human organs like a brain and they had preserved human fetuses at different ages. After a quick walkthrough I got to enter the physics classroom. The physics teacher was sitting at his desk just relaxing and was super laid back like pretty much every other physics teacher I know. We spoke very briefly but then I had to move on. Of all the school visits, this one was by far the most fun. The students and faculty really didn’t want us to leave but we didn’t either. It probably took us at least 45 minutes to head out due to the constant requests for group pictures and selfies. Unfortunately we had to leave as our day was completely packed full.

How to Spend a Day Off?

About one week into our program we were given a day off. There were so many options for things to do! Some people were just going to relax at the hotel. Others were going to walk through Lima to do some shopping. There were some that went to a art museum. So what did a few of us decide to do? To go for a boat tour of the Palomino Islands.

Joints in these layers of sedimentary rocks.

That sounds completely harmless but on this tour we would be jumping into the ice cold Pacific Ocean (61°F)! During their Winter! To swim with sea lions!

The Humboldt (Peru) current brings up cold water from the Antarctic. We would be jumping into this.

Off we went on our day off. The seas were very rough, the air was foggy, but spirits were high. On our way to Palomino Island we passed other islands where we saw things like Peru’s version of Alcatraz (no longer in operation), pelicans, cormorants, Humboldt penguins, other birds, and of course sea lions! It is estimated that there are between 5,000 and 8,000 sea lions on this island. As you approach the island, all you can hear and smell are sea lions. Unfortunately due to rough seas and poor visibility my pictures did not come out too well. I will try to upload some when I can pull some off of my camera after I get home.

As we approached the island it was time to put on our partial wet suits and jump into the water. I stood on the side of the boat with my 360 camera in hand and without hesitating jumped right into the frigid water. At times it was hard to focus on the sea lions as most of my energy was spent fighting the waves crashing over my head and the currents. The 15 minutes in the water felt like an eternity. When it was time to get back on the boat I tried to use my frozen arms to pull myself up onto a boat that was moving quite significantly into the waves. I did make it back on the boat (spoiler) and once we returned to the hotel it took the rest of the day to warm back up. It was worth it though.

This video was taken with my 360 camera and it works best when viewed on a cell phone or tablet as you can pan the video. When I get home I’m going to try to upload it again to see if I can get it to be less grainy.

These images came from manipulation of my 360 video.

A Journey Back in Time

To better appreciate the Peruvian culture, we were exposed to Peru in both the present as well as the past. Since school was not in session on a Saturday we took a trip to Pachacamac, an important sacred site just outside the city limits of present day Lima.

Only a few images will be added here for brevity. To see more images from Pachacamac, look on my Peru trip page sometime late July or early August.

One of many pyramids with ramps at this complex. This one has been excavated more than most.

Throughout the centuries there were four different groups that lived here: the Lima, the Wari, the Ychma, and the Incas. This complex covers approximately 1,100 acres and consists of buildings made of mud bricks. As each subsequent culture conquered the previous, they built upon this area and by looking at the types of bricks used archeologists can determine which culture built what.

Notice the different style bricks that make up the different layers.

My history of this area is incomplete but I will share what notes I have. The Lima culture worshipped sea animals as well as the Moon. Then sometime ~ 600 CE the Wari conquered the Lima. Sometime around 1100 CE the Wari culture was conquered by the Ychma. Around 1450 CE the Incas conquered the Ychma and not too long after (1533) the Spanish arrived and thus ended the rein of the Incas.

The city of Lima goes right up to the borders of the Pachacamac grounds. Who knows what was lost when the land around this complex was developed?

Pachacamac was the god thought to have created the Earth. This god most likely has had different names throughout history but this is what the Incas called him. The Spanish were thought to have destroyed an 8-foot wood-carved Pachacamac idol but one was found in 1938 that looks exactly as it was described by the Spanish. It was found in a room protected by a door covered in shells.

The door that protected the idol. My picture of the idol isn’t very clear so I am uploading this instead.

The Incas performed human sacrifices atop one of the pyramids found here. This site was called the Sun Temple and was situated at the top of the hill, overlooking the ocean. Young women were raised in a nearby building thats purpose was pretty much only to house the women to prepare them for either sacrifice or servitude. The most attractive young women were selected for sacrifice which was a big honor.

This is where the Incas conducted their sacrifices at Pachacamac.

This complex was also used a burial ground for anyone that died. Bodies were wrapped in textiles based on social class. They were put in the ground in the fetal position with a burial mask. Estimates are that 80,000 people were buried here. Thirty-thousand people were buried in front of the Painted Temple (Wari). A few were taken to study and the rest were returned to the ground. This is just one of many reasons why cremation or composting is my preferred burial method!

Not sure the significance but I thought it was cute!

For lunch we went to this placed called Dpaso which was right down the road. The lunch was buffet style (I had to try almost everything) with live folk dancing that would take place every 15 minutes or so. This was similar to the other dances we had seen (other than this dance called the Alcatraz). Following that, we did go outside for something new. Horse dancing!

Horse dancing!
For dinner I had lomo saltado de alpaca over a quinoa risotto.

Día del Campesino

Access to Wi-Fi is becoming increasingly scarce so posts are going to be even fewer and farther between. I’ll be completely off the grid for the next 72 hours.

We were originally scheduled to have our third school visit on this morning but it turns out it was a holiday, Día del Campesino, and public sector employees were off so school was not in session. This holiday was originally meant to celebrate the indigenous population and the farmers of Peru. Most people would not consider this much of a holiday from work as they would have to work extra to make up this missed time (for example, working an extra hour a day). With our morning plans cancelled, we learned more about the city of Lima itself.

Huaca Pucllana

Huaca Pucllana is a solid pyramid made of adobe in the district of Miraflores. The location of this pyramid really catches you off guard. You are driving through apartment buildings, stores, hotels, and restaurants and then right in the middle of that is a pyramid! The Lima culture likely built the first pyramid here with the Wari and Ychsma cultures expanding on it. From what we were told, the top is flat which was most likely acted as some sort of trading post. The adobe bricks are stacked vertically (bookshelf technique) which is not as effected by seismic activity. There are over 300 Huacas (holy sites) in Lima but none are this preserved. We just drove by it on our way through the city.

It was hard to get good pictures in Lima because there air is so hazy. This was also through the window of a bus.

Additional Landmarks in Lima

The Plaza San Martín was built in 1921 to celebrate the 100th anniversary of Peru’s independence.

Statue at the Center of Plaza San Martín

Plaza Mayor is where in 1535 Francisco Pizarro laid foundation for the city of Lima. Pizarro and his men did a lot of really bad things to the Inca people prior to this happening. This spot was chosen because of its proximity to three rivers, the fact that it does not see extreme temperatures, and it is close to the ocean. The fountain in the center is from 1651 but most buildings are from the 20th century due to damage from earthquakes. Around this plaza you can find the presidential palace, city hall, and the former Archbishop’s palace which is now a museum. Fransisco Pizarro’s body can be found within this cathedral. For some reason I don’t have any pictures from this plaza so here is a picture of another church (Iglesia y Convento La Merced). This is the oldest church in Lima although it has required frequent renovations due to earthquakes.

Built in the baroque style

Our final morning stop was to the Catacombs of the Basilica of San Francisco. This is a Franciscan monastary which was founded in 1546 and like so many other buildings has faced earthquake damage over the centuries. The tiles on the wall were from the early 1600’s and came over from Seville, Spain. The wood used in its woodwork comes from cedar trees cut down in Central America. In the catacombs beneath the monastary are the remains of 25,000 people. It was a public cemetary and all demographics were buried here. Use of these catacombs ended in 1821 when Peru became an independent nation. Within the library there are over 25,000 books in different languages and different topics dating back to as far back as the 15th century. Due to humidity and sunlight many of these books are damaged beyond repair and cannot be removed from their shelves. The monastery does not allow photography within its walls so I have no pictures to share.

Festival of Folk Dances at Las Brisas del Titicaca

After yet another fulfilling meal, we were off for a cultural activity. We would get to see some traditional folk dances. The Brisas del Titicaca Cultural Association is a non-profit organization with 60 years dedicated to preserving, promoting and disseminating the various cultural expressions of Puno and Peru. Due to a morning that took longer than expected and a long lunch we missed half of the show.

This is just a sample of the folk dances we saw

Overall it was a pretty relaxing day. It was nice to see some of the historical parts of Lima.

A Totally Different Kind of School Visit

This is the second of two parts on our third day in Peru. Eventually I will get caught up! I promise that the rest of the blog posts won’t be this long. There is just so much to say! It was an incredible experience.

One of three courses for our lunch. This dish had seafood prepared three different ways.

Institución Educativa N°5117 Jorge Portocarrero Rebaza

From our first school visit we immediately went to lunch and I definitely ate too much. This is a recurring theme and it is a result of large serving sizes, multiple courses, and all the food being so good. Once lunch was finished we were back on the bus and headed to a different part of the city. This school was located in the Comas district which is one of the poorest districts in Lima. Although significant progress has been made in building infrastructure it still has a long way to go to ensure that all residents have equal access to necessities. As we grew closer to the school the homes became much more dilapidated and the roads were no longer paved. I’ve wavered back and forth about sharing a picture of the neighborhoods surrounding the school but I decided against it. Instead here are pictures of the program for our school visit.

This part of Lima has a large population of people that moved to the city from the Andes and therefore many of the students speak Quechua in addition to Spanish. In some households, the parents/guardians only speak Quechua. When we walked through the main gate we found lines of students along both sides of the walkway. Many of the students were dressed in native attire. As each of us walked in a student took us by the arm and escorted us to the main courtyard. Once we entered the courtyard another student escorted us to a line of chairs at the far side. The rest of the students, and many family members, sat on the bleacher-style seating that surrounded the courtyard.

Students escorted our group as well as the distinguished guests into the courtyard.
I’d like to think that the llama is the hero of this story.

Once we were all settled there were several speeches and introductions made. After all those were completed students from the school performed some of their native dances in front of everyone in attendance. There was some sort of ceremony with these four groups coming in from four different corners and I would find out several days later that these four groups represent the four quarters (Suyu) of the Incan empire: Chinchay Suyu (NW), Anti Suyu (NE), Conti Suyu (SW) and Colla Suyu (SE). I don’t have any clear pictures of any of the groups but I do have some videos of some of the other dances. Enjoy!

As soon as the dances were over everyone just got up and left. I figured that this was the end of our visit to this school. Walking through the courtyard was a gauntlet of excited students. Just like the previous school, many students wanted selfies with me. At one point I looked up and I could not see anybody from my group. Where did they go?

Was I Left Behind?

No, no I wasn’t. Apparently the school visit was far from over. As I walked around the wall I found another courtyard and this is where everyone went. Around this courtyard were tables set up for different disciplines and students stood around each one to present what they have been working on in school. It was hard to really hear what was going on because of all the excitement and the neverending stream of students looking for autographs/selfies. There was a table for la interculturidad (interculturality) which to be honest I wasn’t quite sure how it fit this theme. It was a collection of objects students had created.

At the conclusion of their presentation students walked to the table, picked up the objects, walked to a teacher, and presented it as a gift. I got a nice basket made out of recycled newspaper. They must have known that I have recently discovered my ability to construct baskets. Another teacher got a large garbage can made out of recycled paper while this other teacher got this elaborate box made for fathers day which consisted of family photos.

My newest basket! This looks like something we could do with our environmental club students.

The next table I visited was the science table. At this table students were talking about the Peruvian biodiversity. I was able to admire the incredible posters that students created and I was able to taste a delicious tea made out of a plant called muña. The science teacher at this table was so excited to meet me she kept inviting me over to the table for more pictures. We may look to see how we could create a partnership between our classes in the future.

A student drew these incredible pictures. So much talent!

The third table I will discuss was for mathematics. Once again, students demonstrated some impressive work. I was only able to catch a small part of it but students tried to model how to use a quipo, a system of knotted strings used to record numbers. After the presentation I spoke with the student that is holding the microphone in the picture below. He is 15 and has an interest in physics. When he found out that I teach physics he was very excited! At the age of 15 he has already started taking physics classes and has already taken calculus. We briefly spoke about the joys of integration.

Math!

Not too long after this the crowds of students started to disperse. There were a few more selfies/autographs and I spoke to the science teacher one last time. Our visit to the school was finally coming to an end, an hour or so after we were scheduled to leave.

The Visit Was Not Over

We were now brought into one of the classrooms for a dinner prepared by the teachers. The dinner would consist of traditional Andean foods as well as chicha, a traditional corn beverage. They claimed that it was not fermented but we could tell what fermentation smelled/tasted like. Over dinner we introduced ourselves to several of the teachers from the school and they introduced themselves to us.

Peru has always 3000 varieties of potato!

Next came the gift giving. This school was so generous with the gifts that we were provided and just like with the morning school I felt bad that they spent some of their limited resources on us. I was grateful for the hospitality and their generosity.

The last thing on our agenda was that two of our teachers gave brief presentations to the faculty that had attended dinner with us. Once those were completed we were able to say our goodbyes, take a few more group photos, and return to the bus. We were scheduled to leave around 5:00 p.m. but left closer t0 9:00 p.m. I’m glad we had the opportunity to visit this school. Its amazing just how much pride these students have for their school and just how late they would stay to meet us. It was definitely worth the late night and I do hope that I can build a partnership with this school in some capacity.

But the Night Was Not Over

Yes it was. This time it was over.
