A pulse wave as shown in the first video. A pulse wave is just one wave that is emitted it is the shape of a half circle, or a wave.

Periodic wave is a wave that is constantly going, kind of like oscillating. It moves with a constant speed that does not change.

A transverse wave by definition is “a wave vibrating at right angles to the direction of its propagation”.

A longitudinal wave by definition is “a wave vibrating in the direction of propagation”, longitudinal waves include sound waves or vibrating waves.

“A Place at The Table” Questions responses

One example of food insecurity in this film is of an unemployed single mother of two named Barbie. Like so many other unfortunate Americans they had to live off of junk food like chips and ramen noodles because they are cheaper than actual fresh foods like fruits and vegetables. After one whole year of looking for a job Barbie finally found a full time job, this should make her fine now right? Since she now has an income that exceeds the one required in order to receive food stamps. She wasn’t even given time to get on her feet, she just lost her assistance from the government right away even though she has been employed for barely any time at all, and probably, hasn’t even received her first paycheck yet. Another example of a person with food insecurity in the movie was a girl who’s father worked on a ranch, but also had to work as a janitor at a school because he wasn’t getting enough money from his ranching career. To cope with food insecurity the girl had lunch made by the school and went to a food kitchen hosted by the church that took place every Wednesday evening. Like so many other unfortunate Americans she and her family has to resort to buying junk food which is much more affordable that fresh fruits and vegetables that actually have a good nutritional value. I think people who are uneducated are more at risk of being food insecure. Mainly because they have a lower chance of getting a great job to supply themselves with adequate nutrition, but also because if they are in a struggle for money they may not know how to acquire resources and help from the government and other food assistance programs such as food banks. Young single parents are also at high risk because they can’t just leave their children and go to school in order to seek a better future for his or her family. My personal reaction to the move is I felt bad for a lot of the people but I was not surprised that so many people are food insecure in America. I am well aware there is a huge amount of people that don’t have enough to eat even though America has more than enough food to feed its people. I was not really surprised by any of the information presented. If I was in a position to directly influence food insecurity I would do a few things, first I would find a way to cut down on food waste, in 2014 a study by the USDA revealed that 31 percent or 133 BILLION pounds of the 430 billion pounds of food went to waste. If we cut down the food waste by only 25 percent we could still be saving billions of pounds of food. The second thing I would do is make fresh fruits and vegetables more affordable. I understand it kind of makes sense that fresh fruits and vegetables are more expensive because they actually have a good amount of nutrients but the prices are ridiculous. Fresh fruits and vegetables need to be more affordable of people who are not fortunate enough to afford them will just keep eating junk food and going down the road of diabetes, obesity, and early death

October Foods Lab Reflection

Mr. Brett

 

I chose to reflect on our buttermilk biscuits lab because although simple, they were the second most enjoyable thing we made this October. The process of making these was no challenge but they still tasted like it took a couple of hours to make. I enjoyed this lab because it was very straight forward and or simple, it was just satisfying to overall. The final product turned out better than i had hoped, I honestly wasn’t expecting much because of the simplicity but they were very delicious. My partner for this lab worked relatively well, there was a little but of a language barrier but we were fine. I in fact already recreated this recipe at home and they turned out just as fluffy, golden brown and flavorful.

 

I chose to reflect on the chocolate almond Biscotti because in my opinion they were the most delightful food we have made all month. some may disagree and say the waffles were the best but im not much of a waffle guy. I enjoyed this lab very much, like the buttermilk biscuits it didn’t take a rocket scientist to make the ideal Biscottis. My group worked very well during this lab, we just put in all the required work as a team and executed all of our tasks with no problems. I would maybe make this lab again during the winter to go with a nice cup of hot chocolate, i don’t know for sure but I think you can keep them in a container in your cupboard for an alright amount of time which is a major plus for me.

Newton’s Laws

 

I’m sure we have all heard of the brilliant scientist Isaac Newton who is famous for his law of gravitation, which was a one of the many brilliant discoveries in the scientific revolution in the 17th century. His law of gravitation was everything in the universe is in some way attracted to each other. We will be looking at Newton’s three laws, videos demonstrating them, explaining why the specific law is demonstrated in the video, and maybe why the law may not exactly apply to the example if it does not.

4449EC45-CD47-4679-903E-63F7FBB49B96-1m3nyo4

Newton’s Third Law

Newton’s Third Law put in brief terms is: every action has a reaction. In this video a tennis ball falls off of a table and bounces back up into the air. The ball falling off of the table is the action, the ball bouncing back up is the reaction.

8A418A92-264B-412B-8E17-C13EB6F12C15-1pjiy8m

Newton’s Second Law

Newton’s Second Law summed up is the acceleration on an object correlates to the magnitude of force put behind it to put it in motion and mass of the object. In the video there is a softball and a tennis ball both with around the same mass. The softball is flicked and it goes forwards some distance, The tennis ball is then thrown across the ground with more force and it also goes forward some distance. the Tennis ball had more acceleration because it had more force even though it had the same mass therefore the magnitude of force is proportional to the acceleration of the object. However if we were to change the type of material to maybe a 1 lbs rock ball and a 1 lbs paper ball, the acceleration may not be the same due to paper being effected more in an environment with air resistance.

219FEBA0-CDBE-40EF-918A-53E1261F8353-21bc9gh

Newton’s First Law

Newton’s first Law, or the Law of Inertia, is when an object that is at rest stays at rest, and an object that is being moved by a force stays moving unless there is an opposing force to stop it. In this video you can see that at first there is a tennis ball that is not moving, it is not moving because an object that is at rest must stay at rest unless a force acts on it. When the ball is pushed it rolls until eventually stopping. But Newton’s first Law states that an object in motion must stay in motion, why does the ball stop if Newton is right? The ball would only have kept moving constantly if there were no opposing forced acting on it. Since the ball was rolling on the floor, the wood caused a force of friction that made the ball come to a stop.

Does Caffeine Stunt Your Growth?

Does Caffeine Stunt Your Growth?

A lot of us in our early years have wanted to try coffee but we’re told no by our parents

because if you drink coffee at a young age it will stand your growth and make you short. The

myth that caffeine stunts your growth is a misconception and is not true at all but is still a common

belief. There is absolutely no concrete evidence that caffeine does so, and I will give you a few

reasons why it does not. First off, where did this myth originate from? Why do or did some of our

parents think this myth was true? The misconception that caffeine stunts your growth is from a time

where people thought coffee caused osteoporosis and osteoporosis was thought to stunt your growth.

There are some problems with this theory: caffeine does not cause osteoporosis, and osteoporosis

usually does not stunt your growth. Maybe our parents told us this as children because they wanted to

keep us away from caffeine in general. I think this because coffee is one of the most heavily

researched foods and you would think people would be more informed about it. A study that involved

81 adolescence for 6 years was conducted to compare the bone density of people that take in more

caffeine to people who take in less. Those with high caffeine intake had the same bone density in the

end as those with lower caffeine intake so this should pretty much debunks the myth completely. A

reason why coffee drinkers may have low bone density is because coffee drinkers tend to take in less

milk and other calcium containing beverages. In conclusion caffeine in fact does not make your bone

density lesser and will not make you short.

Capital Punishment in “Two Fishermen”

English 11

Capital Punishment in “Two Fishermen”

Capital punishment AKA the death penalty is when somebody is killed by authorities because of a crime they have committed. Methods of carrying out this punishment have gotten more humane as time went on. The methods of capital punishment are: hanging, gas chamber, electric chair, firing squad and lethal injection. If the story “Two Fishermen” took place in Canada then the timeline would be around 1865-1976 because capital punishment in Canada was introduced in 1865 and was attempted to be removed but it was not in 1914. Capital punishment was finally abolished in 1976.

In the story a character named Thomas Delaney was executed for killing a man who raped his wife. I highly disagree with the decision to execute Thomas because the rapist would likely have been executed himself because in 1865 only treason, murder and rape are considered crimes bad enough to be executed. Thomas shouldn’t have been executed because he didn’t really commit murder even though he killed somebody, he was only defending his wife from the rapist. Lastly he may have accidentally killed him because there was no mention of him using a weapon and you can accidentally kill somebody with your bare hands when you are very mad, especially if your wife is getting raped.

How will plants grow with rain water, sugar water and tap water?

HYPOTHESIS: If I have 9 plants and I water 3 with rain water the other 3 with tap water and the last 3 with 5% sugar water (100 ml of tap water mixed with one flat tbs of sugar) then the plants watered with rain water will grow better because some tap water has a small amount of chlorine which could not be good for the plants and the rain water is all natural with nutrients from nature (lakes, rivers etc.) and the sugar water will be second biggest because it is just tap water but with extra nutrients but could be dangerous for the plant.
INDEPENDENT VARIABLE: Type of H2O

LEVELS OF INDEPENDENT VARIABLE AND NUMBER OF REPEATED TRIALS
The Independent variable is the 2 different types of water that will be used to feed the plants. The 2 levels are tap water and rain water. Each type of water will be feeding 3 different plants.

DEPENDENT VARIABLE AND HOW MEASURED
The plants are the dependent variables I will be measuring. They will be measured in Centimeters with a ruler.

CONSTANTS/CONTROLS
1. The amount of water given to each plant.
2. The amount of soil given to each plant to sit in.
3. Plant seeds
4. Sunlight received by each plant
5.) placement of plant (makes sure rain cant contact the plants from the sky)
6.) the starting height of the germanium plants and parsley plants
7.)

Materials: tap water 300 ml for each week you conduct this experiment, rain water 300 ml for every week you conduct this experiment, bucket, pot, soil, 3 bean plant seeds, 3 parsley plants, 3 geranium plats, gardening gloves, ruler, space, pencil, paper, eraser, watering pot / cup, Lab sheet, table, measuring tape, measuring cup, tea spoon, sugar, you will need 15ml or 3 teaspoons of sugar for every week you conduct this experiment.
PROCEDURE:
Step 1: place 9 flower pots on balcony or inside beside large window, it is imperative that the pots have equal sunlight the entire day so pay attention to your pot placement. Also make sure that rain water from the sky cannot reach the plants.
Step 2: fill up each pot 2/3 way up with soil
Step 3: place 6 green bean seeds in pots A1, A2 and A3
Step 4: plant same size parsley plants in plant C1,C2 and C3
Step 5: plant same size germanium plants in pot B1, B2 and B3
Step 6: water plants A1, B1, and C1 with 100 ml of regular tap water
Step 7: water plants A2, B2, and C2 with 100 ml of rain water
Step 8: water plants A3, B3, and C3 with sugar H20 (sugar H2O is 100 ml of regular tap water mixed thoroughly one flat tea spoon of regular white sugar)
After step 6 & 7 Water each plant with their designated type of H2O every week
Step 9: every week take precise measurements of height with a ruler (take measurements in centimeters). Also use your eyes to try to spot a difference in color and appearance.
Step 10: after 4 weeks take your final measurements with your ruler or measuring tape and compare the physical characteristics (color, brightness, standing tall or leaning over?) of the pairs of plants.

Keep in mind Sugar water = 100 ml of water + 1 flat teaspoon of sugar

Background Information:
I chose to use beans, germanium and parsley because one is a plant, one is a flower and one is a bushy plant.
the sugar will kill the plants if the water has too much sugar in it
According to https://gardening.stackexchange.com/questions/700/is-rain-water-better-than-tap-water-for-plants the rain water will be better than tap water with a clear visual difference.
According to http://urbangardenguide.com/homepage/indoor/is-tap-water-bad-for-plants/ city tap water contains fluorine and chlorine which can slow growth of plant
According to http://www.livestrong.com/article/548438-is-tap-or-rain-water-better-for-plants/ rain water is more acidic in different regions.
Rain water is more pure than tap water
There are many mixed answers about sugar water, some say it does nothing, some say it is better and some say it is actually dangerous for your plants.
According to https://www.quora.com/Does-watering-plants-with-sugar-water-help-them-grow the negative effects of sugar to plants are long term so we will see in the coming weeks.
5 ml of sugar (1tea spoon) in 100 ml of water makes it 5% concentration sugar water according to my calculator.
Rain water in BC is not toxic
Tap water in BC is clean to drink
Sources say you should have around 7% sugar in water for healthy plants
If bean plants are bent put a stick to make them up right

Observations:
At week 0 the parsley plants are all 13 cm (all 3 plants)
At week 0 all 3 germanium plants are at 17 cm tall

Bean plant watered with sugar H2O is the first one to sprout

The beans watered with sugar water is 6 cm while the other plants are just sprouting at both around 3 cm
The bean plant watered with sugar H2O already has some leaves while the other 2 plants both have much smaller leaves
The bean watered with rain water has larger leaves than the bean watered with tap water
The plant watered with rain H2O water seems to be catching up to the plant watered with sugar H2O in vertical height wise.
The plant watered with tap water is taller than the plant watered with rain water
The sugar water plant had the most seeds sprout.
The germanium and parsley plants take long to grow so there is little difference in height.
Rain water was better for all the plants besides the bean plant (Vertical height growth wise).
The flower on the geranium with tap after looks fuller and healthier than both the other geraniums.
The sugar h2o plants seem to be the tallest
The tap water plants are taller than the rain water plants
The sugar and rain water geranium flowers look very dry
The water seems to be dissolving the soil in all pots
The sugar water bean plant seems to be making a bean in week 4
All the parsley plants look the same in the end

Conclusion
This experiment investigated what is the best type of water to water your plants with: tap water, rain water or sugar water (100 ml of tap water mixed with 1 tea spoon of sugar)? To investigate this experiment there were 3 Geranium plants, 3 Bean plants (6 bean seeds in each pot) and 3 parsley plants. One of each type of plant will receive 100 ml of rain, Sugar, or tap water twice a week. Every week record height and physical appearance of each plant, Do this for 4 or more weeks. After 4 weeks the heights were recorded to see which water made which plant grow the tallest. Results showed that for the bean plant the bean watered with the sugar water grew the tallest at 42.5 cm but it was also the very first to sprout and the first to grow leaves. The second tallest bean was watered with regular tap water at 35 cm and the shortest bean plant was watered with rain water at 29 cm which really surprised me because rain water is supposedly the best water to water plants with. For the Geraniums the tallest plant was watered with sugar water as well at 28.25 cm. Second place was really close with only 1.25 cm difference, the flower watered with rain water at 26.5 cm and regular tap water at 25.25 was last place. Something really surprising with the Geraniums was that the plant watered with tap water had the fullest and most healthy looking flower while the other two looked the same but very noticeably let healthy than the tap water one. The tallest parsley plant was watered with tap water at 27.5 cm, second was with sugar water at 25.5 cm and last was rain water at 22 cm. All of the parsley plants have the same appearance and shade of green throughout the whole experiment. The performance of the rain water was surprisingly not good compared to the other plants; it was even beat by tap water so maybe pollution could be affecting the water that comes from the sky. Sugar water seems to be the best for growing plants quickly but sources say that sugar water is not good for plants long term and the experiment was only conducted for 4 weeks. I was surprised that the tap water could beat the rain water in some areas because sources say that tap water contains chlorine which isn’t good for plants but maybe BC just has some really good tap water. My hypothesis was: If I have 9 plants and I water 3 with rain water the other 3 with tap water and the last 3 with 5% sugar water then the plants watered with rain water will grow the best because some tap water has a small amount of chlorine which could not be good for the plants and the rain water is all natural with nutrients from nature (lakes, rivers etc.) and the sugar water will be second biggest because it is just tap water but with some extra nutrients but could be dangerous for the plant. My hypothesis was mostly negated because I said that the rain water will be the best but none of the rain water plants were the tallest and they were the shortest in the parsley and bean plant. I said that the sugar water was going to be the second best but it was actually THE best height wise in watering the plants because it had the tallest bean and Geranium plants. I said tap water was going to be the worst but it was actually second best. I was surprised at how negated my hypothesis was. Finally if I had the chance to repeat this experiment these are some things I would change. I think it would be a lot simpler to just use 9 bean plants and we would get more accurate results but just for the bean plant. Second I would make the experiment go on longer because sources say that the sugar water is bad for the plants long term but the experiment was not long term as it was only 4 weeks long. Something else I considered doing was testing what is the best percentage of sugar water for watering plants and I think that is a great alternative experiment related to this one.

For take your kid to work day I went with my mom to the hospital. Not because I was injured but to learn about her job which is X-Ray Technologist. An X-Ray Technologists  is the person that takes X-Ray pictures of you when you may have broken a bone or are injured. The pictures below are of an X-Ray machine and what an X-Ray looks like imageimage

To become an X-Ray Technologists you must be very good at working with other people because you have to communicate with the patient and the doctors for your job to run smoothly, you need a high school education to enter a college for a diploma in medical radiography, you must also enjoy working with visual images and technology and must also have the desire to create positive, meaningful expierences for the patient.

Taming of the shrew induction scene project

Sean, Parsa, Eric December 16, 2015 Mr. Barazzuol, Block D Taming of the Shrew, stop motion induction scene project

“Taming of the Shrew” is a play made by the famous poet names William Shakespeare. It starts off with a main character named Sly. Sly passes out in a bar drunk and then the lord with his men come into the bar and take him so that they can prank him. When Sly wakes up he wakes up in a palace full of rich paintings and servants eager to serve him (the servants are part of the prank). Sly is obviously very confused at this point but he is convinced that he is a lord and was very ill. The illness that he thought he had made him sleep for a very long time and he couldn’t remember a thing. The wife Sly thinks he has comes into the room and Sly wants to sleep with her but she said that if they do it he might get sick again. Page leaves the room and the servants enter. The servants have brought in some players that will present a play that is about two people named Grenio and Tranio that go out to look for wives. They meet with a father that has two daughters named Katherine and Beonce. The two men are shocked due to the extremily rude behaviour of the girl named Katherine and they say she was born in hell. Neither of the brothers want to marry Katherine so they are both trying to marry Beonce but you can’t have two husbands.

I enjoyed the filming of this project but we ran into a few problems along the way. First we where a little bit rushy so we where getting out hands and fingers into some of the frames so we had to delete individual frame which was stressful. Second we downloaded the wrong app, we downloaded “imotion” instead of “stopmotion” which made the voice part especially hard becuase we had to record the voice outside of the app, we couldn’t record the voice in the app because we got the wrong app by accident so it wanted us to pay $3.50. But thanks to mr Robinson he edited all the voice clips I made into our video. Aside from the problems I think this was a beneficial experience becuase I learned what it might be like to be on a stop motion cartoon or movie set and how hard it really is.
