QUE VA A PASAR CON EL CLIMA??

In the water class, for our third unit, we had a very rushed schedule.  We actually had an interesting Field Experience to the Chicago River to meet a scientist who sampled water from the river to examine how the floating gardens in the river filtered metals out of the river.  Unfortunately, this project fit very well with our unit #2 on water filtration, but because of the schedule (including a nasty snow storm on Halloween that delayed us!) we postponed this FE until unit #3.

A second FE that was very interesting was a trip to the Field Museum to view an exhibit on water.  It was a very cold and windy day, and it's a long walk to the museum from the train.  But, once we arrived, we got to visit a photography exhibit of 'green infrastructure' including a picture from the Jardine plant that we had visited during Unit #2.  After viewing the exhibit, we went to a classroom in the top floor of the Field Museum and simulated global warming with students acting like CO2 and H2O molecules  (plus a photon!).

These experiences helped us think about global warming, which is the main topic of our final action project.  I selected a city that I lived in for three years some years ago:  Mexico City.  It's a fascinating city -- so huge, so diverse, so much culture.  It's even more mind-boggling to think that it was built on top of a swamp a thousand years ago.  Because of this environment, high in the mountains, with difficult access to water, I wondered how climate change might affect Mexico City.  In my slideshow below, you can see my conclusions.

In conclusion, this unit was really short -- not as much time to look into effects of climate change like clouds or study more carefully the greenhouse effect and how it works.  But I did enjoy seeing a sample of cities from around the world and considering the average range of temperatures.  And I learned a lot about the different types of radiation from the sun.

LENTILBALLS (TM)

For our food class this term we have beeen studying lots of interest and very important things. For instance, we did lots of baking. And we needed to learn some math and fractions becuase a lot of recipes have fractions. One thing that I enjoyed was seeing a farm in a restaurant. It didn't look like a farm, it looked someone's garden but really big. They called it a farm anyways so thats cool. We talked about leaveing agents emulsifers and protein. The major nutriitions are proteins, fats, and carbohydprates.   For our Action Project, we need to substitutie something in a recipe. Some people are substituting a emulsifeer. Some people re substituting a leaveing agent. I will do a substitution of meat with lentils instead.   for my experiment, I used the following meatball recipe: 1lb lean (at least 80%) ground beef 1/2cup Progresso™ Italian-style bread crumbs 1/4cup milk 1/2teaspoon salt 1/2teaspoon Worcestershire sauce 1/4teaspoon pepper 1small onion, finel...

A WALK ON THE RIVER

Image
 Welcome to my introductory project that's introducing WATER and the SDG's!  We have had a buys week starting school, learning about the building and where we can eat lunch naerby, meeting all our friends, and larning LOTS of names.  In our classes we began to learn some things that are imporatnt for the class, like the SDGs.  That stands for Sustainable Development Goal, and it's imporatant for us because of the problems we have to learn about.  We also didn't learn some things, like our teacher won't tell us where he's from.  And I learned about Action Proejcts, where we create work instead of taking a test. For my very first action project, I am creating a poster.  My poster is trying to capture how cool it is that Chicago has a riverwalk.  For our FE we walked along the Riverwalk as a class, and observed how the peolpe use the river.  I saw a ton of boats.  The chairs were fun too.  I made a poster about the water, did you know ...

SEEING REFLECTIONS

Image
Finding reflections in the real world is an interesting exercise.  They might not seem obvious right away, but once you start looking for them, you can find them in many places.  I'm going to find a type of reflection that's of interest to me, and offer three different ways to measure or quantify the reflection using mathematical terminology. Where I looked for reflections?  The video game "PONG".  It was created in 1972, and is famous as one of the most basic video games.  It's a simple game, still entertaining to play today -- although it's not quite as exciting as current video game releases.  But it relies on the basic geometry of reflections, as you move your 'paddle' to bounce a ball back and forth.  Only by understanding reflections can you play the game effectively. The first way to measure the reflections in Pong is using the angle.  In the screenshot below, you can see the ball approaching the paddle. The player needs to move the ...
