Collisions and Temperature

2) Fast

3) When I slide the temperature gauge upwards to increase heat, the molecule begin moving faster at an increasing rate. When I slide the gauge lower for lower temperature, the molecules slow down at a considerable rate until they eventually stop. The molecules stop because the total energy input meter is lowered, where as when I increase heat the total energy input meter is at full capacity. The temperature level is in fact measuring total energy.

4) When temperature increases, the total energy increases, therefore the molecules move faster.


Collisions and Concentration

4) The molecules will speed up because there is more movement of particles within the space(higher concentration), so it increases the total average energy. The molecules are more likely to collide into one another because of the total energy within the space and the amount of particle moving around.

5) The amount of molecules being added to this equation limits the reaction, because the more molecules added the higher total higher average energy. The temperature also limits the reaction because it controls the amount of added or decreased energy. To change the reaction of the molecules, you can increase or decrease the concentration of molecules within the space, or you can increase or decrease the temperature to change the total energy which totals the amount of collision between the particles.

6)    Another factor that can affect a reaction rate is variations in state. More specifically the medium in which the reaction occurs. The kind of medium could be anything from liquid vs. solid, gaseous vs. non gaseous. If the variable in a chemical reaction depended on different matter such as if in the case that Molecule A (fig 6.2), was a solid and Molecule Bc (fig 6.2) was a liquid, the reaction would definitely be affected largely. Because of different substances, molecules move differently.
       Pressure is another factor that affects reaction rate. Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction which involves only solids or liquids has no effect on the rate. Increasing the pressure of a gas is exactly the same as increasing it's concentration.

My walking shoes

Believe it or not, I have decided to use this as an artifact for PE. This being a picture of my navy blue keds which I refer to as "walking shoes" are considered an artifact because they demonstrate the amount that they are used for walking. I wore these to the Stanley Cup Final last night downtown, and when I got home that night, my toes were practically poking out of the ends of them. We did a fair bit of walking last night as the transit systems were completely jammed with masses of hockey civilians either making a troublesome ruckus or desperately trying to get home. 

These blue keds have been through alot as you can quite clearly see, as they have touched the streets of many places treking for many miles in total. They probably have a little more life to see yet, as that dreaded hill up to Windsor House won't walk up itself.

Wilderness Survival Trip to Gambier Island

Gambier, a small quiet island located in Howe sound, a short 20 minute boat ride from horseshoe bay terminal. Inhabited by many deer, a few humans, and other woodland creatures, this island is very quiet and peaceful compared to it's close neighbour bowen island, which is a popular island for residents and campers. With windsor house, we went on an overnight survival trip to gambier island. This trip can technically be counted as a PE artifact because of the hiking we did on this trip. Little may it be, we did hike up, with large camping packs, from the water up into the forest where we scouted out ideal locations to set up camp.

All in all it was a successful expedition, and we survived!

Flour Sack Child

Teenage pregnancy

According to a Planned Parenthood, more than 1 million U.S. teenagers -- one in nine women aged 15 to 19 -- become pregnant each year. Whether or not the teenage mother decides to get an abortion or keep the baby is a personal decision on ethics. For the thousands of women who decide to keep the unplanned baby, have a tough road ahead of them as their are many health issues involving teenage pregnancy, various money struggles that effect some people, ethical controversies within family and friends, and emotional stress that has to be dealt with. It’s hard enough to take care of a baby when you’re mentally and physically ready and stable, but when you’re a vulnerable women between the ages of 12 and 20, without proper support from friends family or spouses, babies can change a life forever. 

The Flour Sack Baby Project

In order to demonstrate a powerful point regarding the difficulties with teenage pregnancy a interactive project was devised called the flour sack project. The Flour sack baby was devised to demonstrate the responsibility involved in managing a family which includes a baby. This project can be done with two people representing a spouse relationship to equal out the hardship or with a more difficult yet common single parent. The ideal purpose of this project is to gain the the realization of the commitment of time and energy it takes to have a child and the demands that a child makes on the parent/parents.

Regarding the Child

- This experiment will be done over the time of one week and will either be done between two people (spouse parents) or will be done by one person (single parent)

- Buy a sack of flour and decorate it creatively without damaging the flour inside or the paper bag it comes in. (You may draw on eyes and dress it.

        - Name the child and make a “mock” child certificate/ social insurance card.

- Carry around the child all day, every day for the next week. If you have important engagements such as work or sports practice, arrange for your spouse to take care of it or arrange for a daycare to care for it (parents)

- Keep a baby book log with you at all times in order to mark down when you “change the babies diaper” and “feed it”. (Writing down that you are caring for your baby over certain intervals of time)

- Set up a crib in your room and set the baby in it to sleep each night.

Comparing Two Ancient and Powerful Art Forms.

  Ancient Egypt vs Ancient Greek

Ancient Egyptian Art is the various historic art forms of the lower Nile Valley from 5000 BC to 300 AD. It is widely recognized around the globe for it’s standardized postures and symbolism in painting sculpture and architect form. Most of the surviving art comes from ancient tombs and monuments and is preserved in museums and historic sites to preserve the beauty and the knowledge of the past. Ancient Egyptian art forms are generally characterized by their heavy use of symbolism, extreme care and detail in god and goddess pieces and their use of art to make the afterlife pleasant.

Another nationally popular and known art form is the art of ancient greece. The particular style has influenced and developed the culture of many other countries sculptures and architecture. This infamous art form inspired millions of European artists and into the 19th century dominated the art styles of the western world. As you can see, art form ancient greece art helped develop much of the art today by inspiring and influencing many artists across the globe, but now the question is, what makes greek art so powerful and widely recognized, what are it’s specific traits. Well ancient greek art is very detailed and anatomically accurate. Greek art consists is known for it’s beautiful architecture which has developed many historic cathedrals and buildings in greece and all over the world for that matter, and stone carvings and sculptures developing the concept and beauty of anatomically correct portraits. Polykleitos, a very famous greek sculptor exercised the concept of sculptures based on natural anatomy. A very famous piece of his that is an early example of classical ancient greek art is the “Spear-Bearer.”

Polykleitos's "Spear-Bearer"

When comparing ancient greece art forms to ancient Egypt’s we see two strong but very different forms of art. Egypt's art being very symbolistic, ritualistically powerful to all the people of egypt, and full of standardized poses expressing and portraying gods and goddesses. Whereas greek art is famous for it’s anatomically accurate sculptures, influence on the renaissance art culture and development, and very detailed and influential architecture that still sculpts most of the world leaving the mark of ancient greek. Ancient art forms and extremely important and commonly studied genres of art because of their astounding influence on modern day art and development of art forms, the powerful role art played in ancient greece and egypt at the time, and the inspiration it sparked in millions of people.
