Math "Height of A Building"

Today, we worked mainly on how to roughly estimate the height of a tall light post, and we did that by using a shadow. By looking at the shadow and the "triangle" the pole made, and comparing it to a ruler as an equivalent, we could divide the shadow of the pole by the shadow of the 1 meter ruler to get the answer, which was 25 meters, while our group got ≈ 30.82 meters. As the ratio of the shadow of the pole to the pole is 22.5 : X, and the ruler was 0.73 : 1 meter, if you divided 22.5 by 0.73, you would get the approximate length of the pole. However, as we took the measurements five minutes apart, and the sun wasn't in a perfect position to measure the best, we did not get very close to the heigh of the pole, which was actually 25 meters.

Building compeleted :) vLog day 3 and 4

Hey guys, so we finished our building, got past the "magnitude 9" earthquake, and successfully, kept it up without much movement. Watch the vid for more info.

Day 1 and 2 --- Earthquake Proof Building Project

Hey guys, so we've started building an earthquake
proof building (project for school again), and
we got the base done -- it took a while, had some problems,
but it was worth it :). Base works really well, and we'll post the blueprints next time.

Earthquake-proof Buildings

These buildings are less solid than a short 3 story apartment building, and can sway and move in an earthquake, whereas a 3 story building would be stiff and fall over when the bottom is shifting.

3A. My wellness wheel would run pretty smoothly, but the psychological wheel would trip it up.
3B. I am most well in the physical section, as I really exercise a lot and do many things.
3C.I am the least well in psychological, as, as I don't really do the best I can sometimes.
3D. I would want to make my Physical wellness better and get it to a five, by getting more sleep every night.

Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
Soccer outside: 1 hour	None	None	None	Soccer with my brother - any amount of time	Cricket - 2 hours Soccer with brother -1 hour	Soccer - 1 hour

These five benefits of exercise caught my attention:

• Makes body more agile. 
• Enhances immune system. 
• Strengthens the heart. 
• Improves posture. 
• Enhances quality of sleep.

One benefit I want to improve on is to enhance my quality of sleep, as I usually get tired during the day. In my opinion, I think that I am not getting enough exercise, but it is better than before, where I didn't do anything at all. If I need to make some changes, it would be to get more exercise, and I would do that by doing an intramural after school. I will also maintain it by doing it every week.Exercise helps you maintain physical, emotional, and spiritual wellness.

Investigation 1 Blog Post

I have found that changing a percentage to a ratio has made a lot of ads seem much clearer if there is a large difference or the huge percentage difference. As there could have been just 3 people voting, and if one person says no and two people say yes, it is automatically a 50% difference,but there is not much difference in the number of people.

Part to part ratios are ratios which compare one part to another part, whilst part to whole ratios compare the whole thing to one part.

You can scale or use equivalent ratios to solve a proportion by making both a fraction, then making the denominators equal to compare them properly.

You can scale or use equivalent ratios to find out if 9/11 of a packet or 6/7ths of a packet is more, and choose the one that is more.

What moves the plates?

The core of the earth under the lava is so hot, that it makes the magma under the crust move, which causes it to move in a pattern called a convection cell, which basically is a pattern where the magma rises, cools, and goes back into the mantle. The path that it is moving in is called a convection current, and depending on which way it rotates, (anti-clockwise or clockwise), the plates will move in that direction. The crust then spreads in two different directions: apart from each other, and directs outwards. The old segments of the crust will then end up under the earth, heated up by magma,  and the new rock will be formed at the top.

Basketball

I demonstrated a pass, pivot, and a spin during the video, for example when I was in trouble from Thomas, I quickly passed to Ben, and he tried to shoot the ball. An example of a pivot is when he was walking up to defend me, and I spun, around, pivoted, but then got the ball stolen off me.

I can improve my accompanying and evading movements by making sure to pass better, and also to do more cut-fakes, as I didn't do many of them.

Unit 1 Reflection

1. The common properties of all polygons are they all have at least three sides, and have at least 180 degrees. Also, the sides do not cross each other. Exactly two sides meet at every vertex.
2.The measure in degrees tells you if it is an acute, obtuse, straight, reflex, or right angle. Some common benchmark angles are the ones that are divisible by 30°, 45°, or 90°. Examples are 120°, or even 315°.
3. To estimate angle measure, one strategy is to draw a midpoint on the middle of the angle. Then, use a compass to draw a circle around it. Afterwards, you can draw in the "benchmark angles", and then estimate from there. Or, you could just do an estimate by drawing it in your head. To find accurate measurements with tools, put the centre of the bottom line of the protractor on the part where the two angles touch, make sure the angle line on the bottom is aligned with the bottom line on the protractor, and measure.
