Weekly Blog(3/25/17)Coriolis Effect

https://sites.google.com/site/sed695b4/projects/demonstration-equipment/coriolis-effect-jennifer-kim

     This week in class we learned about the Coriolis Effect. The Coriolis Effect is basically how the winds move with the earth or else the winds would be at 1,600 kph (1,000 mph) around the equator. But, it is way more complicated than that. This diagram shows how the winds move in the different hemispheres of earth.

     This week for the SE&P I communicated information because we worked with our team and did research to work on a sheet. I got better at sharing my information and working with a team because I figured out what is important to tell my team and what is not.

Weekly blog (3/17/17) Tornados

     This week in class we learned about weather, and we also learned about storms and how they happen. This is a picture of a tornado because a tornado is a storm and I found the very interesting.

      The SE&P is we used models because we all did research and put it on a document. This brought me toward mastery so I can get better at close reading and finding what information I need.

Project blog(3/10/17)My thermos

     In this project we learned about heat transfer. We got with a team and created a mug that could hold minimum of 250 milliliters. Our mug was made of polystyrene (styrofoam) because it has billions of air bubbles inside it that trap the heat, duct tape because it has rubber which is a good insulator because it prevents electrons from traveling through it, and wool yarn because wool has fibers that the heat grabs onto.

     Before I started I knew these were good insulators but I had know idea why.
   
     I am proud of this product. I really like how it holds in heat really well and isn't uncomfortable to hold. I don't like how the lid after being opened a closed a lot stopped closing all the way.

     We did our work differently because we didn't buy a glass jar or just use a water bottle covered in tape. But ours (The bottom piece) was made from styrofoam cup with the lip taken off in side a bigger cup. The I put scraps of foam on duct tape and wrapped it around the cup a few times. The I stuck it in the bottom of a gatorade bottle filled with duct tape and foam scraps. The I wrapped to whole thing in duct tape, then in yarn, then in duct tape again.

     Next time I would like to make the seal between the two pieces work so it did not drip.

     This week in class we learned about heat insulation and conduction. We our task was to create a mug using that holds 250 milliliters that keeps the liquid as warm as possible. I learned that polystyrene (Styrofoam) is a good insulator because it has billions of micro bubbles of air in it. I think learning about this had to do with global warming because air is a good insulator and that is how all that heat is staying on this planet and melting all the ice.

     This week S&EP is we demonstrated what we learned about heat transfer by making coffee cups that should keep the coffee as warm as possible by preventing conduction (when you touch the coffee cup and it's hot) and preventing convection (when you feel the warm steam coming off the top. I have gotten good at constructing models because I do it so much and even though it's always different, I learn something new.
