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.
