Chemistry Homework-Questions

1. What are the three (main) states of matter?

solids, liquids, and gasses.

2. Explain the properties of a solid, liquid, and a gas. Talk about the movement of particles.

Solids- hard; particles are in a tight, organized arrangement
Liquids- free flowing; fluid; particles are close to each other, but not in a tight arrangement
Gasses- particles move rapidly, and have much larger spaces between each other than liquid or solid particles


3. Changing the state of matter is a physical change. When energy (in the form of heat) is added or taken away matter can change from one state to another.

It will be a physical change because you are not changing the chemical build-up of the matter, you are just changing the form it is in. Adding or taking away energy can change the state of matter. For example, if you add heat to ice, you get a liquid (water), and if you have enough heat, the water will turn to a gas. An example of taking away energy is condensation. You are taking energy away from the gas to turn in into a liquid.

Gr 6 Final Scripted Performance

This week was my last week of drama. I performed in two short plays for my final grade. One was titled, 'The Grave' and another was titled, 'Remote Chance'. Here is a reflection on my trimester in drama:
I think projection was one of the things I did best. I could hear what I was saying pretty easily. I think I was using my diaphragm because I didn't feel like I was straining my throat, and my voice was audible. While I was performing, I did feel that I had vocal variety, in 'The Grave' especially. But when I watched the video, I realized I could've been a little more dramatic with my voice. I think my voice wasn't very varied in 'Remote Chance'. I couldn't see my facial expressions in the videos, but I think I did have facial expressions that suited the situation my characters were playing. I am really proud of 'The Grave' group because I think I did my very best in that group, and I really liked how the story did turn out scary. I was also proud of my 'Remote Chance' group because that play was really funny, because of everyone's contribution to that play. Overall, I think I could've put more effort into 'Remote Chance' because my voice sounded pretty flat and didn't have enough expression to show what my character wanted to say.

At the beginning of drama, I gave myself an 8.5/10 to show how eager I was to perform and do this class. Now, I am probably around a 9/10 because I have learned to be a little more brave while I perform and I also know how to use a lot more vocal variety. Before taking this class, my voice was pretty flat when I presented. Now, I know how to change my voice. To sum it all up, I am glad I took drama this year.

Fraction Comparison Reflection

Why is it a good thing to know several ways to compare fractions?

The way you compare fractions depends on the fractions you need to compare. Some methods are easier with certain fractions, and others are harder with certain fractions. For example; when I want to compare the fractions 11/23 and 15/29, benchmark fractions would be a good method to use. 11/23 is slightly lower than a half, and 15/29 is a little greater than a half. To compare those two fractions, you could cross multiply, but that would take longer and be more complicated than using benchmark fractions. Both methods will work, but a certain method is more efficient and easier to compute.
 

Shooting Kabul Boiling Point Reading Response

In Shooting Kabul by N.H. Senzai, Fadi reaches his boiling point when he realizes it wasn’t his fault that Mariam got lost. Fadi feels guilty throughout the book that it was his fault his little sister Mariam got lost because of him; in this scene he tells his art teacher, Ms. Bethune about it. In the chapter before, Fadi figured out that he didn't win the photo contest (which was his chance to win a trip to India, and attempt to save his sister who is lost in India's neighboring country, Pakistan), and he reacted in a bad way. So, Fadi came to Ms.Bethune to apologize for his bad reaction, and explain why it was so important he won that contest.

Ms.Bethune tells Fadi, “It wasn’t your fault that poor Mariam was lost.” ...

Ms. Bethune says, “Look, honey, bad things happen to good people. And you were in a bad, bad situation. What if you had stopped to put that darn Barbie in your bag and both of you had been left behind.”

“Oh,” said Fadi. I hadn’t thought of it that way.(page 237)

Fadi’s biggest pressure throughout the book is that it was his fault Mariam got lost and here he realizes things could’ve been worse, and it wasn’t all his fault. After this, Fadi starts to feel more positive and doesn’t worry about it being his fault as much. This scene also clearly changes the way Fadi thinks about it, which he wasn’t able to do over the entire book. Fadi also told his family about how he thought it was his fault Mariam got lost, which he had been avoiding the whole book. A theme this leads to is to always have hope because Fadi felt so hopeless and bad about what happened, but he realized that he needed to have hope. Fadi also learned not to blame himself and put so much pressure on himself, even during tough times. At the end of the book, he came clean to his family, and didn’t feel very pressured.

Cartesian Diver Explanation

In science, as part of our density unit, we did the cartesian diver experiment. Here is my explanation:

 When the diver is floating at the top of the bottle, it is positively buoyant, because it is floating. When we squeeze the bottle, we are decreasing the volume of the bottle, and increasing the mass of the diver. This is because the water is going into the diver, increasing the mass. The ballast to make the diver to make it sink was water, because the water is going into it to make it heavier. When the diver is in the middle of the bottle, it is neutrally buoyant, because it is just floating in the middle. So, squeezing the bottle slightly causes the diver to become neutrally buoyant. The diver is negatively buoyant when we squeeze the bottle hard, which makes it sink to the bottom. When we squeeze the bottle hard and water goes into the diver, the density of the diver must have turned to more than 1 g/cm3 because it is sinking. When the diver is at the very top, the density would be less than 1 g/cm3, because it is floating. The density would be around 1 g/cm3 when the diver is in the middle. 

Sportsmanship In Everyday Life

Sportsmanship is playing a fair game, how you play the game, and your general attitude during the game play. Sportsmanship is how you act during the game. An example of good sportsmanship would be shaking your opponent's hand at the end of the game. One way I have demonstrated sportsmanship this year is congratulating the other team in the floor hockey unit. When the other team scored a goal, my team would compliment them on that.
In PE, some ways anyone can demonstrate sportsmanship are playing by the rules, trying to avoid arguing with the opponent, congratulating the opponent when they score, and shaking the other team's hand at the end.
Sportsmanship can be used in everyday life as well as on the sporting field. Some ways you can do this are: encouraging others, helping people who are injured, and congratulating others when they win or triumph in something.
1 new way I want to try demonstrating sportsmanship on the sporting field is by congratulating the opponent when they score more often, because I know that this is a really good example of sportsmanship and that I don't do this very often.
