Broca’s area is the portion of the brain in charge of speech, language processing and comprehension, and controlling facial neurons. We know this, and much more concerning the Central Nervous System, thanks to Dr. Paul Pierre Broca who made these discoveries over one hundred and fifty years ago. Pierre Paul Broca was born in 1824 to parents who initially would not allow Broca to pursue an academic career. However, with the immense success he gained while completing his studies, his mother agreed to permit him to pursue his passion in academics. After years of rigorous study and close workings with highly reputable doctors, in 1849, he was declared doctor of medicine and his accomplishments continued to pile up. A few of his accomplishments include describing muscular dystrophy as a main condition of muscle and rickets as a nutritional illness. Dr. Broca was also actively involved in promoting public health and public education, learning more about infant mortality, and military service for the armed forces of France. As well, he was actively involved in introducing the microscope which aided in the diagnosis of cancer. Following countless awards and promotions to higher positions within the realm of medicine, in 1867, Dr. Broca was summoned to the chair of surgery at the Faculty of Medicine. From Broca’s career, the discovery of localization of brain function stands out far above the rest. His knowledge was gained after studying the brain of a speech impaired patient after his death. Tan, the patient studied, is now well-known in the medical field because it was his brain that lent us a wealth of knowledge. Thanks to Tan’s brain we know that the area of the brain accountable for speech processing, language comprehension, language production, and the control of facial nerves are located in the left hemisphere of the brain. This region is named after Dr. Broca and is referred to as Broca’s area. When damage is done to Broca’s area, it is known as Broca’s...

...Surface Area Formulas
In general, the surface area is the sum of all the areas of all the shapes that cover the surface of the object.
Cube | Rectangular Prism | Prism | Sphere | Cylinder | Units
Note: "ab" means "a" multiplied by "b". "a2" means "a squared", which is the same as "a" times "a".
Be careful!! Units count. Use the same units for all measurements. Examples
|Surface Area of a Cube = 6 a 2 |
[pic](a is the length of the side of each edge of the cube)
In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.
|Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac |
[pic](a, b, and c are the lengths of the 3 sides)
In words, the surface area of a rectangular prism is the are of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same.
The area of the top and bottom (side lengths...

...Explain each of the areas of learning and development and how these are interdependent.
Personal social and emotional has three aspects, making relationships, managing feelings and behaviour and self-confidence and self-awareness. This area is all about the child’s relationships with other people and themselves. Children need to develop relationship with the people around the for example the children they play with and come into contact with. The staff that work in that room and their family members. You recognise the relationship people have by observing them and if it’s you and a child you know if that child is close to you. Managing feeling and behaviour is all about the feeling children get and what they know about them and can they recognise them within other people. And the behaviour side of it is knowing what to do and what not to do and can tell if there is any harm coming towards anyone. They can also recognise the behaviours in other children. Self-confidence and self-awareness is about the child knowing when they have done something new the can say look I have done this and are happy about it. Generally aware of themselves and what they are doing.
Physical development has two areas of development in one being moving and handling. This is every physical movement that the child does so from drawing with a pencil using a three finger grip to jumping around outside and climbing the pirate ship. The other...

...a place where they belong.
The interest areas should allow the children choices to explore, make things, experiment, and pursue their interests. The choices should include"quiet zone" areas for reading, art activities, and games. Areas should also be set for block building, dramatic play, woodwork, sand and water (discovery table) for active engagements.
All the interest areas should accommodate a few children at a time, in a well defined space, so that children can focus on their work, and the play can be more complex.
Interest areas work in a good way when the materials you use are attractive, inviting, and relevant to the children's culture and experiences. The areas should not be overwhelming or frustrating to the child, but it should challenge their thinking.
Interest areas should be labeled, and all things should have a designated home, so children can share in clean up time.
My interest areas are catered towards pre- school to kindergarten. I found it difficult to choose just 3 areas of interest, but I decided that I would use a block area, dramatic play and a discovery area in my setting.
What do children learn in the block area?
I chose the block area because children learn best when they are encouraged to explore, interact, create and play. The block area...

...What conditions must apply before an area can be considered safe? A safe area according to the definition from the Encarta is summed up as an area where one can find refuge and safety, while living in security, (Encarta. 2007). Would you consider the Ryerson Campus area to be safe? This depends on a certain individual's bias which is based on the gender and age of that individual. Another factor that comes in to play is the time of day you are viewing the area, different opinions may be generated on an area if it were daytime as opposed to night time. Personally I'm an 18 year old male and from my exploration I generally found the Ryerson area to be unsafe, especially during the night time. Many factors came in to play for me to generate such an opinion such as lack of light in certain areas, narrow alley ways and construction that can be dangerous to anyone walking within the area.
The general opinion on safety during daytime from Ryerson students is that it's not a big concern because you're in broad daylight and there are always people around. A first year Electrical Engineering student, Obaid Ansari responded, "So far I found Ryerson to be very safe during the daytime, in fact I found it safer than my high school because there are always lots and lots of people around!", when asked how he felt about the safety of the Ryerson...

...Investigation Lab Report
Hypothesis:
I predict that as the surface area of the canopy increases, the time it takes for the parachute to fall also increases. This is because the air resistance is larger, therefore the drag is increased. So the speed of the parachute decreases. This is because the forces (air resistance and gravity) are unbalanced. The change in air resistance is important because the larger the surface area of the canopy, the more air particles it is ‘hitting’; therefore the air resistance is bigger.
Variables:
In our investigation, the variable that we changed (the independent variable) was the surface area of the canopy of our parachutes. The result that we measured (the dependent variable) is the time taken for the parachutes to fall to the ground. The controlled variables were the altitude of the fall (height from which we dropped the parachute) and the weight and size of the plasticine. This is shown in the table below.
Variable | Control |
Height from which we dropped the parachute | * This was to make sure the parachutes fell from the same distance. * We did this by using the same balcony. |
Weight of the Plasticine | * This was to make sure only the area of the canopy affected the speed of the parachute. * We did this by weighing our plasticine on a scale. |
Shape of Plasticine | * This was to make sure only the...

...displaces, it will float, but if it is heavier, it will sink.
The force of buoyancy is important in many different areas, and especially in the making of ships. The surface area that is touching the water of the ship is very large, due to the shape of the hull, and that, beside the density of the ship, is what keeps the ship floating. An important example of how surface area affects buoyancy is when people float in the water. Everyone knows that it is much easier to stay afloat when we are lying on our backs than when we are in a standing position in the water. But how does the surface area of an object affect its buoyancy?
Aim: To investigate how changes in the surface area of pieces of wood of the same mass affects their buoyancy.
Hypothesis: That the larger the surface area of the piece of wood, the more buoyant it will be.
Variables:
The Independent Variable is the surface area of each piece of wood.
The Dependent Variable is the buoyancy of the each piece of wood.
The Controlled Variables are:
o The weight of each piece of wood and its hook
o The amount of water each piece of wood is measured in
o The spring balance used to take measurements must be the same (to prevent any inaccuracies)
o The size of the container used to hold the water
Apparatus:
4 pieces of wood attached to hooks, each weighing 100g, with different surface...

...of a Three-Dimensional Cubes
and Surface Area in the Classroom
Written by Vanessa Kinsey
There are several uses in our daily lives that involve calculating the area of objects or places. Many of these daily recurring calculations require using acquired skills to figure out the area of three-dimensional objects. When introducing the concept of surface area to 5th and 6th grade students, they need to first know what three-dimensional objects look like and understand what the definition is, or the difference between a two-dimensional and a three-dimensional object. Through the use of manipulatives, instructing the students to change a two-dimensional piece of paper into a three-dimensional object, the students should gain a better understanding of the concept. It is helpful for students to create and hold a cube to fully understand what a three-dimensional cube looks like. Once students gain an understanding of the concept of a three-dimensional cube, they will be able to understand the concept of finding its surface area with ease.
To introduce the concept of surface area, I will begin reviewing the concept of finding the area of a two-dimensional object such as a square or rectangle, and remind them of the formula for area is length times width (LxW). Next, I will begin to link this review with the new concepts. For instance, if the length of each side of...
