ADL15 Mutation Story- Angelman Syndrome

Part 1: My story

Angelman Syndrome gene story

Part 2: The making of my Mutation Story

Some of the questions I answered to aid me in making my gene story:

  •  How does the syndrome effect my host’s life?
  • how does the protagonist of my story work inside the cell?
  • How does the syndrome effect the functioning of the host’s body?
  • What caused the mutation to occur?

Some digital tools i used to aid in the making of my story:

  • Google chrome
  • bookmarked pages that I used to research my mutation
  • other websites then Wikipedia
  • Microsoft Word

Order I did my work:

  • Research mutation
  • brainstorm and make notes about mutation/story
  • forget about story until day before due date
  • write story
  • proof read my story
  • check criteria
  • make Edublog post
  • check criteria again
  • sit back and relax

Overall I found this project enjoyable. I love writing and getting a chance to write a story about something that relates to both writing and science inspired me. I don’t think there’s anything about this project I would do differently, only that I should’ve finished sooner 🙂

Edible DNA model

edible DNA modelToday in class we created a model of DNA (deoxyribonucleic acid). We used licorice, toothpicks, and coloured mini marshmallows to make a double helix, the shape of DNA when it’s outside the cell. DNA is a molecule that carries the genetic instructions for creating organisms, developing organelles, and reproducing cells and viruses. It decides what you look like.

Skype chat with Tanya Harrison

skype chat

Last week our class had a Skype chat with an astroscientist named Tanya Harrison. Her line of work includes studying space but more specifically, Mars and the rovers sent there. She used to be an employee at NASA and is a professional photographer, as well as that she has a Ph.D. in geology.

During the Skype chat we talked to Tanya and asked her questions about her line of work. She was extremely knowledgeable about space and what she does and taught us a lot of things a textbook couldn’t. During the interview, each group in our class got the chance to ask Tanya a question about space, her line of work, schooling, or any general questions she’s willing to answer. Some of the questions we asked her were:

Which rover sent to Mars was she the most involved in? She worked with multiple rovers over the years but she’s been the most involved with the rover “Curiosity”.

What’s the longest time a rover has lasted in Mars? Tanya said the longest a rover has every lasted on Mars was a whopping 12 years, even though it was only supposed to last about 90 days. That record is held by the rover “Opportunity”.

How long does it take to build a rover that can be sent to Mars? Her answer was that it takes NASA about 8-10 years to design and create a rover that could be sent to Mars one day.

How much money does it cost to build a rover? Rovers are extremely expensive and it costs about 2.3 million dollars just to build one.

I thought it was a really cool experience to have Tanya Skype into our classroom. She answered pretty much all of the questions we asked her and knew something about all of them. It was a really great way to kick off our space unit in Science, and I felt like I learned a great deal from chatting with her.

 

Energy in our school

A partner and I chose to do our power connections project on our school. We chose to look into how our school is being energy efficient and find some answers to questions we may have about it.

The first ting we did was write up a proposal with some questions we have and things we would like to find out about our subject.20151126_094426

Some questions we wanted to have answered were:

  • What is the school doing already to save electricity/energy?
  • What uses the most energy in our school?
  • How are we working to improve the intake/consumption of electricity?
  • Are there any perks to the amount of electricity we use? disadvantages?
  • Why does our school promote the 1:1 system?
  • Could the 1:1 system be improved in any way?
  • How is the 1:1 system improving our school?
  • Is there a possibility of our school being to energy efficient?

We then put our heads together to decide who would be doing what part of our project and some general guidelines and ideas.

We decided to interview the principal of our school, Mr. Ciolfitto to ask him about our school and possibly get answers for our questions we had. we arranged a date, and after some rescheduling met with him for an interview about our project. first by email, then in person. Here is a link to the audio of our interview if you would like to know all of the information and answers to our questions:

After our interview we decided we wanted to do a video representation of our meeting with Mr. Ciolfitto. We drew out a mind map and timeline of how we wanted our video to look and used that as our outline for our video.

We put together a video slightly different then the original format. After a few altercations and work, out came a video worthy of the viewing of our classmates! (and Mr. Ciolfitto)

 

Currents from the kitchen

In class today we did a lab including different types of fruits and vegetables. In the experiment we created a circuit using a lemon as a battery and hooked up two wires from it to a volt meter. One the two wires connected to the lemon, one wire acted as the negative electrode while the other acted as the positive electrode. One end attached to a copper wire was stuck in the lemon while the other had a piece of zinc attached to the wire and stuck in the other end. This circuit seemed to be used the most and the most effective.

We noticed at the beginning of the experiment, none of the led lights/light bulbs would light up. This was also true for other groups as no one else’s lights would light up. it wasn’t until later that we found out by reading the box, the lights only work when more 2 or more volts are produced. Our fruits didn’t even come close to that which is why they didn’t light. Since the electrons didn’t flow through the bulb we used a volt meter.

We did this experiment with more then one type of fruit/vegetable. We conducted our experiment with both a lemon and a potato. We observed when our fruit/veggie battery was hooked up to a volt meter that the lemon was negatively charged, while the potato was positively charged. I think this was because in the lemon, the negative electrode collected more electrons then the positive electrode, making the lemon emanate a negative charge. the opposite applies to the potato.

I don’t know if this would be the best way to combat the “next big thing” in clean energy because there’s so many better things the foods used could contribute to in other areas. Yes it acts like a battery but it’s also really weak and produces under one volt. To make it the next big thing you would need a lot of that food. Also instead of wasting food to power electronics, the food could be given to people that actually need it. I would rather the industry works on stopping world hunger then using the very thing that can help stop it for gadgets.

Prediction about best fruit/vegetable conductor

I believe the best conductor of electricity that’s a food is a lemon

lemons

I believe that a lemon can be a good conductor because it acts the same way as a battery. a battery contains two pieces of metal called electrodes, and a liquid or paste called electrolytes. When the electrodes and electrolytes connect with a material that can transport electricity well (a conductor). This causes a chemical reaction to occur. In a lemon, a solution of water and a electrolyte (the acid in a lemon) makes a large amount of electrons collect on one end of the electrodes, while at the same time many are lost from the other electrode. This causes a lemon to act like a battery when two different wires are connected to it. The wires act as the electrodes having one become positively charged and the other negatively charged.

Electricity Mind Map

This is a mind map I made that shows my knowledge on electricity prior to the electricity unit we’re starting this week.

20151104_213256

Some Questions I have about electricity that will hopefully be answered throughout the unit:

  • Why does the human race rely on electricity so much?
  • Who discovered electricity?
  • Why was electricity such a big deal when it was discovered?
  • Would the world be a better place if electricity wasn’t discovered at all?
  • Does always being being on devices effect the planet?
  • Does electricity cause global warming?
  • should electricity be a key factor in everyday life?

(Pardon the carpet background of my mind map)
