today in science we created bracelets made out of fruitloops. i find them gross but my partner was happy to eat all of it in the end. basically we chose a word or your name and used the RNA which is somewhat like DNA and created a bracelet out of it. the difference that i noticed between RNA and DNA is the letter coding. the 4 letters in DNA are A,T,G and C. in RNA there isn’t C. instead they replaced it with U. there is probably a better and more in depth way of explaining the difference but this is all i know and understood. So in class i made my bracelet with the coding letters of my name. G = GGG , R = CGT,
A = GCT, C = TGC and E = GAG. i thought this lab was fun and taught me something. here is a picture of my bracelet bellow.
This morning in my A block which is science we started Biology. We learned about the coding thing for cells. we also did an experiment to better our understanding for this lesson. me and my partner (Noah)built a DNA model. the outer portion which is the Sugar and phosphate was represented by licorice. the marshmallows represent the 4 letters that exist in the DNA world. (Guanine) G = green. (cytosine) C = pink (Adenine) A = yellow and (Thymine) T = orange. the tooth picks strung them together.
Here are questions that needed to be answered after my science classes first Astronomy class.
Question and answers:
1. Q: explain what the balloon and dots represent?
A: the balloon represents the universe, the M dot represents the milky way and the other dots are galaxies.
2: Q: Which letter(s) moved farthest from M? Which moved the least?
A: D moved the farthest and C and B stayed the same length throughout the lab. C and B moved the least.
3: Q: summarize the trend: movement of galaxies related to distance from M?
A: The big the balloon got the farther the dots went.
4: Q: How does this experiment model what is occurring in our expanding universe?
A: the galaxies are growing farther apart so when the balloon kept expanding it showed what the galaxies were also doing.
5: Q: in what way does a balloon NOT represent the universe?
A: yes its expanding but i dont think the galaxies are growing larger.
Today for block C and block D i got to watch the spoken word presentation for 2015. To be totally honest i was not really looking forward to these presentations but during C block when i went down to watch, i enjoyed it. some of the presenters were proving a point or opening our eyes to something. some were funny and other not so much. i loved how some of these spoken words were detailed and creative with their wording. i liked the way they could raise their voice at the right time. it made me think about these subjects that they were referring to. it made me think. My favorite ones were the ones that involved humor. but i thought the other ones were very well done.
in poco we have 2 main sources to get electricity. the two sources are, hydroelectric generation and thermal generation. so how hydroelectric generation works is by the hydroelectric dams. this dam has 4 steps to make electricity. 1 is the penstock. water flows from through the huge pipes called penstocks. 2 is turbines. the penstocks spin the turbine blades which spins the turbine shaft. next is the generator. the shaft is connected to the generator. a generator spins a huge electromagnet at a constant pace to generate electricity. the last thing that works for these dams are the transformers. electricity is passed through the transformer.
thermal power station:
these station use fuel such as coal, oil, or gas is burned in a furnace to produce heat chemical to heat energy.this heat then is used to change water into steam in the boiler. the steam drives the turbine – heat to kinetic energy. this drives the generator to produce electricity – kinetic to electrical energy.
read my small essay of sorts. it’s about the whole bring your kid to work day thing. in this post you can read about what my dad does for a living and if i perhaps would like to follow in his footsteps. TOKTW Reflection Sheet 2015 pdf
This is my project redone and better then it was when handed in. when I handed this project in I only focused on one part of this project. The questions portion. I did however get marks for mentioning other points that were a part of the project. Now to bring up my Grade for this project I have to write an edublog post about this project. And this is what this is.
1. Q:What are the everyday uses of this element
A: one example of an everyday use of iron are magnets. Another example is steel. Like paper clips or staples
2. Q:Where is it found on the periodic table
A: metals and group 8
3. Q:What is it’s symbol and atomic number
A: Fe and 26
4. Q:What does the element look like
A: silvery color and stone shaped
5. Q: What are some of the other elements our element mixes with?
A: mixes with almost anything on the periodic table
6. Q:What is the history of the element
A: Iron objects have been in Egypt back in 3500BC. 7.5% made up of Nickle. Iron gave the people in Turkey a better economy. The first person to explain the various types of iron was René Antoine Ferchault de Réaumur who wrote a book on the subject in 1722. People have been using iron for over 5000 years.
7. Q:Is it a harm to the world
A: Iron is a toxic heavy metal. In excess, it can cause cancer, heart disease, and other illnesses.
8. Q:Who discovered this element
A: I never found out who discovered the element iron but it was discovered in approximately 3500BC.
9. Q: How does this element affect you?
A: This element affects me and all humans because iron is the thing that helps carry oxygen to your blood.
10. Q:Any interesting facts about element
A: – iron melts at 1538’C
– Iron’s Elemental name Fe was named after the Latin word “ferrum” which means Iron.
– Irons boiling point is 2861’C
– Iron is one of the cheapest and the most abundant of all metal.
– Iron help carry oxygen to your blood.
– Much of the earth core is made of Iron (or is said to be)
– In plants, it plays a role in the production of chlorophyll. In animals, it is a component of hemoglobin — a protein in blood that carries oxygen from the lungs to the tissues in the body.
– About 90% of all metals are refined as iron.
– Women need more iron then men in their system.
Chemical Symbols and Formulae:
Element symbol= Fe
Number on periodic table = 26
Classifies as = a metal in group 8
Sources of info:
Checking for if the websites are reliable:
After looking into this website more I found that it a very reliable and helpful. It was quiet organized with some interesting points about your certain element in the front and then had a side bar to help you search about other things with your element. It wasn’t biased in anyway. It just showed you the information you were looking for.
This website was helpful with the history portion of whichever element you are researching. On the side of the web page it shows a list of all the elements from A-Z. There is a mini version of the periodic table in one of the corners that highlights the spot where your element is. It shows clearly the history the person who made the website learned. Also mentions where they received their info. The cool thing I liked is that it shows how to say each element in different languages.
This page was interesting. It was different than the other websites I had been on. This website was always being updates when knew information about the element was found. It also showed us the history and mostly everything to know about your element. The facts shown on the page seemed reliable and true on what I had already known and learned.
All this website talked about was the bad things that iron could do to you. The thing I did like about this site is that it asked a bunch of different questions that someone would ask about my element. They also answered the questions with perfect wording and nice structures sentences to help me or the other people reading this web page understand.
Importance of element:
At the beginning I chose the element because it was the only thing my partner and I could agree on. Then after some research of this element I realised it is kinda interesting. The interesting facts I learned from my research and the stuff we learned in class was pretty amazing. The thing that stuck with me the most was how the symbol Fe became the symbol for iron. Cause iron doesn’t seem to fit Fe. There isn’t F or E in iron. But it comes from irons Latin translation. Ferrum. Fe.
The app I chose ” K12 Periodic table of the elements.” I checked the app out and it was pretty cool. when you clicked on one of the elements on the table, it would show you the history and other info about the app. this app helped me learn by teaching me more about the elements on the periodic table. It took a little while to load on my device but it worked very quickly afterwards. The app was very helpful and I learned a lot. I give it 4 and a half stars. (like a movie rating)
I am very interested in learning about the new possibility’s of the future. learning about how mind reading can be possible and how. different things with technology in the future. always wanted to learn about a flying car ever since back to the future.
