Mutation Story
Hello I am Angie but everybody calls me UBE3A. I am one of many of Emma’s genes. I am inherited from Emma’s mother. I don’t work like normal genes about 10 months after Emma was born I stopped working I don’t function anymore like I used. I affected Emma in many different ways when I first stopped functioning Emma became delayed in her daily life activities. When everyone else was crawling and babbling Emma would sit still and stay quiet. As a baby Emma couldn’t do many things she couldn’t stay balanced so she couldn’t walk or really move. She is always smiling and laughing, that is my favourite part. When Emma was about three years old she started having something called seizures. Emma now is about 18 years old some people still make fun of her small head, but she has many people who care for her so she doesn’t mind. Emma doesn’t really talk she goes days, sometimes weeks without talking. Her eyes started to cross when she was about 14 but now they are permanently crossed. She does a lot of hand flapping to communicate with people. Emma faces many challenges daily but that just makes her that much braver. She doesn’t let Angelman Syndrome get in her way of doing what she likes even though it is challenging.
1. why does angelman syndrome occur?
Angleman syndrome symptoms in babies?
Angleman syndrome symptoms in adults?
2. I used basic questions this way I would get a straight answer. I also made sure that I was using reliable sources but checking a lot out to see patterns in the answers.
3. I read through all the criteria. I then started to research the questions and find the patterns to write down the answers. After I started writing to make everything flow and get all the information I found into the story properly.
4. I copied down the links to each website and put them down on a document.
5. I found the process smooth and the writing to be a little more difficult. I think I could have down better to cite my sources. I think I should have used citation machine or a program like that to properly cite my sources.
Expanding Universe
In this lab we made a model of the universe expanding. We blew a balloon up to a size of a baseball, then put a dot by the mouth of the balloon and labeled it M. We then put 5 more dots and label them A-E. This expieriment was meant to show us how far the galaxies are moving away from each other. The balloon represents the fabric of the universe and the dots represent galaxies the dot labeled M represents the Milky Way. We found that the closer the Galaxy the distance increased more than others far away. I think this was a great way to represent the universe expanding because it was a great visual to show and it helped me understand. I still wonder about if two galaxies are far away from each other can they still have a gravitational pull on each other.
Static Electricity Lab
Vinyl carries a negative charge after it is rubbed together with. Acetate carries a positive charge after it is rubbed together with cotton. When two positive charged objects are close together the they repel each other. When two negative charged objects are close together the two objects attract the other. When a positive and negative charged objects are close together they repel each other. When a neutral object is close to a charged object they attract.

Matter Matters
Define: challenge was to inform people about matter in an engaging way.
Dream: PowerPoint, Presentation, kahoot, poster, video.
Design and deliver: we made a PowerPoint presentation and we delivered it over edublog.
Debrief: we worked as a team and found ways to present in an entertaining way. Creativity of presenting could have been a bit more interesting. But otherwise it was a very effective in teaching people.
Oobleck
We did a experiment in science we made Oobleck. Oobleck is made up of two things. Chemical A was a transparent and clear liquid. Chemical B is a white, powdery, thick, and clumpy substance. The properties of Oobleck are a creamy colour, liquid, and solid. The Oobleck acted like a solid when hit fast and put under pressure quick but when it slowed down it turned into a liquid so Oobleck behaves both like a solid and liquid. I think Oobleck is liquid because Oobleck only holds it solid form for a short period of time not majority of the time. It helped me understand that molecules can act in different states when put into it but will reform back into its original state.
