Transcript: free body diagram force due to gravity force due to gravity: - always points down - always called the weight - measured in newtons equation: fg = w = mg normal force - force between an object and surface - flat table can be an example - same magnitude but in the opposite direction (fg) Equation: Fn= - FG normal force: friction - measured in (N) - opposes motion -slows down moving objects -makes it harder to move stationary objects equation: ff = "mu" Fn friction: air resistance - similar to friction - comes from objects moving through the air - slows down falling objects - points up - more resistance the faster an object moves air resistance: tension the force in a string or chain pulls in the direction of the rope Tension: contact force only happens if the object is touching something pushing a cart up a hill can be an example of contact force contact force: balanced and unbalanced forces - balanced force: If the net force is 0 then it is balanced example: 5N to the left + 5N to the right = 0 - unbalanced force: If the net force is not 0, then the object motion changes to match the resultant example: 5N to the right + 5N to the right = 10N to the right balanced and unbalanced forces: how to draw a free body diagram 1. replace the object with a dot 2. draw all forces acting upon the object - start at the dot and point out 3. label all forces how to draw a free body diagram: examples of FBD's ex1) a book being held in the hand. the forces that are acted upon the object are the force of gravity and normal force. ex2) push book on table. The forces that are used in this object normal force, force of gravity, force of friction. ex3) jumping off a plane with a parachute. The forces that act upon are the force of gravity, and air resistance examples of FBD's:
Transcript: "The Secret Name of Ra" Plot Pyramid Diagram Main Characters Ra is the Sun God. He has a lot of power over his creation. Ra is known and can appear in many different forms. Isis is the Mistress of Magic. She can cast spells and make tricks happen. Exposition Ra, the Sole Creator was visible to the people of Egypt as many forms and names. He could be seen as a scarab beetle and a crowned man. He was also know as the Shinning One or the Hidden One. Isis was the Mistress of Magic, wiser than millions of me. The setting was in the country of Egypt. Inciting Incident Isis longed for Ra's power and dreamed she would have a son named Horus and the throne of Ra to give to her son. She knew that nothing was powerful enough to harm Ra, so she decided to use his power against himself. Isis created a cunning and devious plan. Rising Action Isis created a wicked-looking serpent out of a clod of Earth and Ra's saliva. Through the hours of darkness she whispered spells. Climax/ Crisis When Ra approached the crossroads, the spells of Isis began to work and the clay serpent quivered into life. As Ra passed, it bit him in the ankle and crumbled back into earth. His scream was heard through all creation. Falling Action Isis stood among the gods and goddesses pretending to be as distressed and bewildered as all the other frightened deities. Isis told Ra "Few gods can compare with me in wisdom and I am the Mistress of Magic. If you let me help you, I'm sure that can cure you. Resolution Isis said nothing and knelt beside the Sun God while his pain mourned. When it became unbearable, Ra ordered the other gods to stand back while he whispered his secret name to Isis. Isis than agreed to never tell anyone his secret and then she chanted a spell that drove out the poison in Ra's limbs. Denouement Ra returns to the Boar of Millions of Years and Isis is joyful that her planned worked. She now knows that one day Horus would sit on the throne of Egypt and have the power of Ra.

Transcript: Sample Problems How to Draw Them Examples of Forces Balanced Forces (Fbal) How to Label Forces Why They Are Used Free-Body Diagram Free-body diagrams are used to show the forces acting on an object. At rest Forces equal 0 Opposite vectors are the same size Constant velocity 1. Identify the force acting on an object. 2. Identify the direction of each acting force and draw vectors representing the forces. 3. Vector sizes do matter. If the force is greater then the size should be longer. Draw a vector to represent each force. Draw it in the direction the force is being exerted, and label it by the type of force, the object exerting the force, and the object receiving the force.Each vector must be labeled. Speeds up/ slows down Forces don't equal zero/ change direction Vectors are not the same sizes Vectors don't have opposite partners Unbalanced Forces (Funbal) Applied-is a force applied to an object by another object or person. Normal- The support force exerted on an object that is in contact with another stable object. Friction- A force exerted by a surface as an object moves across it.
Transcript: EAL students will have diverse learning styles, may be gifted or have a learning disability, and come from different socioeconomic or religious backgrounds even within the same culture. EAL students will have different exposures to education within their home countries. Identity texts, dual language books, online media as ways to transfer home language knowledge. Treasures Assignment - students will have special objects that are important to them culturally. Accessing EAL students' background knowledge is important for their learning. The tone of spoken words and non-verbal cues are important aspects of language. Underlying beliefs and values often lie at the root of miscommunication. Cultural differences can lead to miscommunication. Schmidt, A. (2008). Rare Books. Flickr (Background Image) Van Syla. (2012). Because of You (background music). France.

Appropriate response of a student with a particular cultural mindset vs. expected response in a Canadian school setting - Scenarios. Culture study of the educational system of various countries. Danger of a Single Story, TED Talks Language may be the only thing students from the same culture have in common. It is important for EAL students to transfer knowledge from their home language to English to assist their learning. Preserving EAL students' cultural heritage and continuing to develop their home language are important factors in their learning. Non- verbal cues: kinesics, proxemics, haptics, artifacts, silence, time. Cultural Values: assertiveness/compliance, dominance/submission, disclosure/privacy, direct/indirect communication, flexible time/time as a commodity. by Karen Leonard March 17, 2014 EAL students are diverse. The 4 stages of culture shock: honeymoon, hostility, humour, home. Assessment, vocabulary instruction, graphic organizers: strategies to help meet the needs of diverse students. Essential Knowledge Background Detail LLED 479: Pyramid Diagram Short-term Information A student's home language proficiency is the strongest predictor of their English academic development. Teachers must be proactive to affirm students' linguistic identity.
