I really enjoyed the chat my class and I got to have with Tanya Harrison, a planetary scientist and a PHD student in geology at the university of Western Ontario, just as our class had done before with Karishma(http://myriverside.sd43.bc.ca/kelseav2015/2016/04/20/google-hangout-blog-response/). It was originally planned to record and live stream but we had a few technical difficulties and it had to be cut short (video chat).
My classmates took turns individually going up to ask the question/s they had prepared last day. These included, her opinion on the colonization of mars, her struggles and interest, etc. We actually got to hear about the evidence of water on mars strait from Tanya herself.
I’m glad I got to learn more about mars from someone with great interest in it.
I am a rare genetic condition caused by the deletion of a chromosome. I was not inherited from the parents of my host body since it is uncommon. Unfortunately for my host, they inherited an unbalanced translocation and are missing genetic material from the short arm of chromosome 5; this caused my host’s intellectual disability and health problems. My kind of condition occurs roughly 1 in 20,000 to 50,000. Luckily for my host they were not born with a heart defect which can occur on occasion with my particular type of condition.
My host has been effected by the negative mutation and has a number of symptoms due to it, such as:
low weight at birth, growing struggles, wide eyes, unusual facial features, higher voice and many more. The body of my host could be considered high functioning compared to others and since this condition was discovered roughly 50 years ago there is not a lot of information or advanced treatments to cope with this condition. My host can go about their daily life fairly easily even though school isn’t catered to their condition they continue to persevere.
I needed to find out about how someone would obtain this mutation, the causes, effects, severity, rarity, and so on and so forth. I used my trusted sites such as YouTube and Wikipedia, and although one could say Wikipedia is unreliable mistakes are corrected very quickly and reading the same information among other sites does strengthen its reputation. Watching videos of parents of children who possess the disorder gives you an inside opinion and observations and one video was of someone who was living with the disorder and how he wished to raise awareness towards it. If given more in class time, my end product would have turned out much more insightful. Another factor that might’ve helped would’ve been a professional or more known information about the disorder.
Purpose: to test which two items when rubbed together create the highest static charge, measured by amount of hole punches the object picks up.
Hypothesis: rubbing the ebony and polyester together will create the highest static charge.
Procedure:
Take a piece of material and rub it with another.
Attempt to pick up hole punches with item.
Repeat process.
Materials:
Wool
polyester
fur
Lucite
plastic spoon
paper hole punches
ebony
plastic bag
cotton
plastic straw
Object one
Object two

Observations: how firmly rubbed together tended to make static charge weaker. Fur tended to be most successful with other items.
Results: rubbing fur and Lucite together creates the highest static charge.
Conclusion: our hypothesis was proven to be incorrect. Fur and Lucite rubbed together attract the most paper hole punches. If we were to do the experiment over again I would’ve taken into consideration keeping the amount of rubs more constant.
Chapter 1.2 talks about how matter changes states, how matter is made up of particles. Matter is anything with a volume and mass. Each particle moves around more or less depending on the state. Chapter 1.2 also talks about elemental and compound pure substances. Solids have a definite volume and form, liquid has definite volume but not form, Gas has neither a definite form or volume.
A change of state occurs at temperature change. A solids molecules are condensed and move slowly; a liquid’s volume is definite but its shape is indefinite, its molecules move somewhat quickly and are slightly spaced apart; a gas’ volume and shape depend on its surroundings, a gas molecules are spread out and move quickly. There are names for each process of change (gas to liquid and liquid to gas have different names).
A chemical change and a physical change are very different. A chemical change would be cooking something while a physical change could be breaking a cup; one’s build up and molecules have changed, while the other has simply changed visibly.
Matter = Anything with a mass and volume
Mass = How much matter in a substance
Volume = How much space the substance takes up
Chemical Change = When substances are combined to create a different substance
Physical Change = Change of state (Solid, Liquid, Gas)
Matter = Made up of particles
There is space between particles, more space between gas particles than liquid, and liquid has more space than solid
Particles are always moving, less in solid and more gas
Particles are attracted to each other
Pure substances, compound pure substances and elemental pure substances,
Elemental = Can not be broken down or split up
Compound = Made up of two or more elemental substances
Qualitative Properties = Describing the substances
Quantitave Properties = Can be measured
We thought of many ways to present the project such as a Prezi or PowerPoint going over all the important information from chapter 1.2, we were thinking of maybe doing a video talking about everything from 1.2, or making a game where you play as a substance and you change states.
We didn’t plan enough and could’ve further extend our explanation. With more time we could’ve presented our information in a more interesting and engaging way.
