​​2023 Semester Only Grade 7th/8th Physical Education Content Review Key Concepts Content • Responsible behaviors • Team Building • Responsible Behaviors o Demonstrate acceptance and respect for people with diverse backgrounds and abilities during fitness activities. Develop strategies for including everyone. o Demonstrate responsible behaviors during fitness activities. Examples of responsible behaviors are controlling emotions, resolving conflicts, respecting opponents and officials, and accepting both victory and defeat • Team Building o Characteristics of High-Performing Teams - Most members of high-performing teams report that it’s fun and satisfying to work on collaborative teams because they are asked to contribute at their highest potential and they learn a lot along the way. Characteristics of high-performing teams include the following: ▪ People have solid and deep trust in each other and in the team’s purpose — they feel free to express feelings and ideas. ▪ Everybody is working toward the same goals. Everyone places the team first. ▪ Team members are clear on how to work together and how to accomplish tasks. ▪ Everyone understands both team and individual performance goals and knows what is expected. ▪ Individuals contribute to the team based on their unique strengths ▪ The team engages in extensive discussion, and everyone gets a chance to contribute. ▪ Disagreement is viewed as a good thing and conflicts are managed. Criticism is constructive and is oriented toward problem solving and removing obstacles. ▪ The team makes decisions when there is natural agreement — in the cases where agreement is elusive, a decision is made by the team lead or executive sponsor, after which little second-guessing occurs. ▪ Each team member carries his or her own weight and respects the team processes and other members. ▪ The leadership of the team shifts from time to time, as appropriate, to drive results. ▪ No individual members are more important than the team. • Warm-up • Cool-Down • Heat Cramps • Hear Exhaustion • Heat Stroke • Dehydration • Proper Attire (clothes and shoes) - color and type of clothing to be worn during exercise in different climates • Proper Hydration - drink water before, during and after exercise especially during hot weather • Warm-up: Gentle exercises that get the heart and muscles ready for moderate to vigorous physical activity. You know when you are warmed up when you begin to sweat and breath more heavily. o Walking or jogging for 5-10 minutes is recommended • Cool-Down: Gentle exercises that let the body adjust to ending a workout. Should last for 5-10 minutes allowing your heart rate and breathing to return to normal. o Include light stretching in your cool down to help muscles relax and not feel stiff or sore afterward. • Heat-Related Illnesses o Heat Cramps: Painful, brief muscle cramps that occur during exercise in a hot environment, caused by dehydration o Heat Exhaustion: A heat illness caused by the body overheating. Symptoms include heavy sweating, dizziness, weakness and rapid pulse o Heat Stoke: A health illness caused by the bodies inability to regulate its temperature. Symptoms include hot, dry skin, elevated body temperature, lack of sweat, hallucinations o Dehydration: Excessive loss of body fluid • Aerobic exercise • Anaerobic exercise • Pedometer • Vigorous • Moderate • FITT • Aerobic Exercise - Rhythmic activity that uses large amounts of oxygen and works the heart and lungs. • Anaerobic Exercise - Activities performed (without oxygen) consists of brief strength-based activities. • Heart Rate - The number of times your heart beats per minute. • Moderate physical activity - An activity with intensity equal to brisk walking. Activities of moderate intensity can be performed for relatively long periods of time without fatigue. • Vigorous physical activity - Movement that expends more energy or is performed at a higher intensity than brisk walking. • Forehand stroke • Backhand stroke • Forehand strokes (racquet sports) are where the front of the hand leads the stroke. o To strike the ball players should stand with their opposite shoulder facing the net, swing from low to high and follow through. Opposite footsteps toward the net. o Follow through by driving the racket forward so that it ends up above the shoulders, pointing up to the sky and in the direction of the ball you just hit. o Hitting the ball too late may cause the ball to land out of bounds. • Backhand strokes (racquet sports) are where the back of the hand leads the stroke. o Begin with a balanced ready position. Transition from large steps to smaller steps as a player closes in on the ball will help maintain balance. Step toward the net with the foot on the same side. o As the ball approaches, the player must move to intercept it, the shoulder must turn to begin the backswing. As a player sets to hit the ball, the backswing is complete. o The path of the racket extends along the intended flight of the ball as long as possible. Contact point for a one-handed backhand is further in front of the body than in a two-handed stroke. o The face of the racket remains vertical through the contact zone. The follow through is high. • CPR • Aquatic safety • Cardiopulmonary Resuscitation (CPR) o Hands-Only CPR Steps: ▪ Call 911 and push hard and fast in the center of the chest (100 compressions a minute) • Aquatic Safety o Swim with a buddy o Take swimming, diving, and water safety or rescue classes to learn the skills to swim and dive safely. o Never swim under the influence of alcohol or drugs o Make sure to check the depth of the water before diving • Free Pass • Penalty try • Rugby Game Play: o free pass: is used to start the match or restart after a “try”. It starts from the center of the field at the halfway line at the beginning of each half. From the touch line (at the place where the ball went into touch) when the ball goes into touch (put into play), and from where the referee makes a mark when an infringement has taken place. o To score in flag rugby you must be on or cross the end zone with your flag on, touch the ball to the ground and say “try”. o A penalty try will be awarded if a try would have been scored if there was not foul play by the defending team. o When a try is scored, the game is restarted by a free pass from the center of the pitch by the non-scoring team. o The player taking the free pass must start with the ball in both hands and, when instructed by the referee who will declare “Play”, pass the ball sideways or backwards through the air to a team-mate. • Rules of the game • Basketball Rules: o The game starts with a jump ball then alternate possession begins. o Five players play on the floor at a time. Players’ positions consist of guards, forwards and a center, o Traveling- is having possession of the ball and moving without dribbling, resulting in a turnover. • Rules • Ultimate Frisbee is a non-contact field sport that combines elements of soccer, football and basketball. The object of the game is for a team to pass the disc from player to player until a pass is completed to a teammate in the end zone resulting in a score. Teams consist of 7 players. • How the Game is Played: o The game is played to 13 points or until a certain amount of time has passed. o All players from both teams begin each point in their respective end zones. Play is initiated with a “pull” from the defensive team’s end zone. The disc is passed from player to player down the field. o Once the disc is caught the “handler” must come to a complete stop. He/she may pivot but must maintain one planted foot at all times (even on the follow through). o The thrower or “handler” has ten seconds to throw the disc once caught. o A point is scored when a receiver catches the disc in the end zone. • Warm-up • Cool-Down • Heat Cramps • Heat Exhaustion • Heat Stroke • Dehydration • Proper Attire (clothes and shoes) - color and type of clothing to be worn during exercise in different climates • Proper Hydration - drink water before, during and after exercise especially during hot weather • Warm-up: Gentle exercises that get the heart and muscles ready for moderate to vigorous physical activity. You know when you are warmed up when you begin to sweat and breath more heavily. o Walking or jogging for 5-10 minutes is recommended • Cool-Down: Gentle exercises that let the body adjust to ending a workout. Should last for 5-10 minutes allowing your heart rate and breathing to return to normal. o Include light stretching in your cool down to help muscles relax and not feel stiff or sore afterward. • Heat-Related Illnesses o Heat Cramps: Painful, brief muscle cramps that occur during exercise in a hot environment, caused by dehydration o Heat Exhaustion: A heat illness caused by the body overheating. Symptoms include heavy sweating, dizziness, weakness and rapid pulse o Heat Stoke: A health illness caused by the bodies inability to regulate its temperature. Symptoms include hot, dry skin, elevated body temperature, lack of sweat, hallucinations • Dehydration: Excessive loss of body fluid • Alcohol • Smoking • Effective Communication • Alcohol o Underage drinking is considered illegal o There are laws about alcohol consumption o Alcohol slows down the ability to think clearly • Smoking o Smoking is the primary risk factor in respiratory diseases including emphysema and bronchitis o Cigarette smoking causes the heartbeat to increase the heart rate o Nicotine in cigarettes stimulates the heart to beat faster, which increases the heart’s need for more oxygen. Carbon monoxide replaces the oxygen in the blood forcing the heart to work harder. • Effective Communication o Includes: ▪ being respectful ▪ Actively listening ▪ Using assertive communication skills when needed • PACER • Push-ups • Curl-ups • Sit and Reach • Fitness Test o PACER: Performed to measure cardiorespiratory fitness o Push-ups: Use to measure muscular strength and endurance o Curl-ups: Used to measure abdominal muscular endurance and muscular strength o Sit and Reach: Performed to measure a student’s flexibility • Digital Citizenship • Digital Footprint • Digital Citizenship: is a safe, responsible, and respectful use of technology • Digital Footprint: is essentially a history of everything you’ve ever done online. Everything you post and do online can follow you through middle and high school, college, and even when you get a job. It has the potential to contribute positively or negatively to your digital reputation. • Positions in Hockey • How the Game is played • Scoring • Hand Placement • How the game of hockey is played o Street hockey is played very similar to ice hockey using the same rules and similar style of play. The only difference is that the players are using a ball instead of a puck and are running on firm ground rather than skating on ice. The game is played with 5 players and a goalie. There are five players on the court at a time with a goalie. Three forwards (2 wingers and a center) and two defenders. • Object of the game o Hockey is a fast-paced team sport, and the object is to outscore your opponent in the allotted time. • Start to play o A face-off will occur after every goal scored and to start off each period. The referee will drop the ball in-between the two centers who are facing each other. There are three periods in a game. • Out of Bounds o If the ball is hit out of bounds, then the opposing team may pass it back in from the side lines. • Scoring o a goal is made when a player either knocks down a cone, or if the ball crosses the goal line. Both goals and assists will be rewarded when scorekeeping during tournament play at the end of the unit. • How the game is played • Players and positions • Basic Skills • How the game of volleyball is played: o A game is played to 25 points. A team must win by 2 points and is called a set. A match is 3 out of 5 sets. o The server must stand anywhere behind the end line on his/her side of the court prior to the serve. The ball may be served underhand or overhand. The player who serves is in the right back position. o Each team may only hit the ball 3 times on its side before the ball must pass over the net. o The teams will rotate clockwise each time they win the serve. o A point is scored every time a ball is not returned properly into the opponent’s court, this is called rally scoring. Thus, both serving and receiving teams can score points. o If the ball hits the line it is considered, in bounds or good. • Players and Positions: o Setters – player who “sets” the ball with an “overhead pass” for a teammate to hit, the setter normally runs the offense o Hitter - the spiker or attacker o Outside hitter - A left or right-front attacker normally taking an approach which starts from outside the court o Libero - defensive specialists, designated for back row only, and wear a different colored jersey. The libero may serve for one player she is substituting for per game. o Blocking - A defensive play by one or more players meant to deflect a spiked ball back into the hitter’s court. To block, move your body in front of the hitter, keep arms in front, straight, palms facing the ball. • Players • Rules • Cues for throwing in flag football • Cues for catching • Scoring • Flag Safety • Defensive Strategy • Flag Football Players Include o Quarterback - The offensive person who is in charge of advancing the ball down the field (either by hand-off or pass), in order to gain yardage, a first down, or to score a touchdown. The QB also initiates and calls the plays. o Center - The offensive person who is in charge of “snapping” or “hiking” the football to the Quarterback. (“Hiking” means to hand the ball between the legs) o Receiver - The offensive person who runs a route down the field to catch a pass from the quarterback in order to gain yardage, a first down, or to score a touchdown • Rules o Interception - When the defensive player catches a pass intended for an offensive receiver o Sack - When the Quarterback has his flag pulled by the defense behind the line of scrimmage o Fumble - When the ball is dropped after being in possession o Line of Scrimmage - Each play starts on the line of scrimmage. The line of scrimmage is the imaginary line where the nose of the ball is placed to separate the offensive team from the defensive team. • Downs - The offensive team then has 4 “downs” to advance the ball to the next 1st down marker. Teams may advance the ball by passing or rushing • How the game is played • How the game of soccer is played o Soccer is a field game between two teams of up to 11 players. o The purpose of the game is to make goals by dribbling, heading, or volleying the ball into the opponent’s goal while defending the teams own goal from opponents. o The ball is put into play at the beginning of the game when a player kicks the ball into the opponent’s half of the field at a distance of at least the circumference of the ball. The kicking player may not kick the ball twice in a row. o Once the ball is in play, each team tries to advance the ball toward the opponent’s goal to score by dribbling and passing it down the field. o Players are free to play the ball in any direction during play. In typical play, players attempt to create goal scoring opportunities through individual control of the ball, dribbling, passing and taking shots on goal

What are some examples of human behaviors that might be considered instinctual? Human instinctual behaviors include newborn reflexes (like grasping), fear responses (like loud noises or heights), bonding between parents and children, facial expressions (like smiling and crying), the fight-or-flight response, imitation, language learning ability, and the need for social connection. In Drive-Reduction Theory, what is meant by a “drive”? What about “homeostasis”? In Drive-Reduction Theory, a “drive” is an internal state of tension or discomfort caused by an unmet biological need, such as hunger or thirst, that motivates a person to act. “Homeostasis” refers to the body’s tendency to maintain a stable and balanced internal state, so behaviors are motivated by the desire to reduce drives and restore balance. How is the Arousal Theory different from Drive-Reduction Theory? Arousal Theory focuses on seeking an optimal level of stimulation, while Drive-Reduction Theory focuses on reducing biological needs. Arousal explains thrill-seeking; drive-reduction explains behaviors like eating when hungry. How does Maslow’s Hierarchy suggest we prioritize our goals? Maslow's Hierarchy of Needs suggests that people tend to prioritize basic needs before higher-level goals. According to the theory, physiological needs like food and sleep come first, followed by safety, love and belonging, esteem, and finally self-actualization, which involves reaching one’s full potential. The idea is that lower-level needs usually must be reasonably satisfied before a person focuses strongly on higher-level needs. Give a real-life example of each level of Maslow’s hierarchy. In Maslow's Hierarchy of Needs, physiological needs include food and sleep, safety needs include shelter and security, love and belonging involve friendships and family, esteem needs include confidence and respect, and self-actualization involves reaching personal goals and potential. Why might Maslow's theory be criticized across different cultures?+ù Maslow's Hierarchy of Needs may be criticized across cultures because it reflects individualistic values, such as personal achievement and self-actualization, which may not be prioritized equally in all societies. In some cultures, community, family, or group needs may be considered more important than individual goals. What is the difference between intrinsic and extrinsic motivation? Intrinsic Motivation comes from internal enjoyment or personal satisfaction, while Extrinsic Motivation comes from external rewards or pressures, such as money, grades, or praise. Which type of motivation do you think leads to more lasting change? Why? Intrinsic Motivation usually leads to more lasting change because the behavior is driven by genuine interest, enjoyment, or personal meaning, so it continues even without external rewards. Extrinsic Motivation can be effective in the short term, but the behavior often stops when rewards or pressure are removed, since the motivation depends on outside factors rather than internal commitment. What are the traits of someone with a high need for achievement? A person with a high need for achievement sets challenging but realistic goals, prefers tasks with clear personal responsibility, seeks feedback, and is persistent. They are motivated by doing well and improving rather than just external rewards. Why might low achievers choose tasks that are either very easy or very hard? People with a low need for achievement may choose very easy tasks because they are almost guaranteed success, which helps them avoid failure and protect their self-esteem. They may also choose very hard tasks because failure can be blamed on the difficulty of the task rather than their ability, which also protects their self-image. What role does the hypothalamus play in hunger? The hypothalamus helps regulate hunger by monitoring the body’s energy needs and signaling when to eat or stop eating. Different parts work together: one area triggers hunger when energy is low, while another signals fullness after eating. It responds to hormones, blood sugar levels, and signals from the stomach to maintain balance. What is the difference between set point theory and settling point theory? Set point theory says the body has a fixed, biologically controlled weight it tries to maintain. Settling point theory says weight is flexible and depends on lifestyle and environment, so it can change over time. What psychological and social cues can influence how much we eat? Psychological cues like stress, mood, and distraction can increase or decrease how much we eat. Social cues such as eating with others, portion sizes, and cultural expectations also strongly influence eating behavior. What are the symptoms of anorexia nervosa? Anorexia Nervosa includes extreme food restriction, significant weight loss, intense fear of gaining weight, and a distorted body image. It can also cause fatigue, dizziness, feeling cold, and in some cases, serious health problems. How does bulimia differ from anorexia? Bulimia Nervosa involves binge eating followed by purging and often normal weight. Anorexia Nervosa involves severe food restriction and very low body weight. How might perfectionism be linked to the development of eating disorders? Perfectionism can lead people to set unrealistically high standards for their body, weight, or eating habits, which increases stress and dissatisfaction. This pressure can contribute to restrictive eating or binge-purge behaviors as they try to “achieve” an ideal body image. According to James-Lange theory, what comes first: the emotion or the physical response? According to James-Lange Theory, the physical response comes first. The body reacts to a stimulus, and then the brain interprets those physical changes as an emotion. How does Cannon-Bard theory explain simultaneous emotion and bodily reaction? Cannon-Bard Theory says emotion and bodily reaction happen at the same time. A stimulus triggers the brain to send signals that produce both the emotional experience and the physical response simultaneously, rather than one causing the other. What evidence supports the idea that emotions are biologically universal? Evidence shows people across cultures recognize the same facial expressions, and even blind people show them, suggesting emotions are biologically universal. Similar brain activity patterns also support this idea. . What are Paul Ekman’s universal emotions? Paul Ekman identified six universal emotions: happiness, sadness, anger, fear, disgust, and surprise. How might facial expressions influence how we feel? Facial expressions can shape emotions through the idea that acting a certain way can influence how we feel internally. For example, smiling may increase feelings of happiness, while frowning can intensify sadness. Body and facial feedback to the brain helps reinforce or even create emotional experiences. Why is it important to recognize that emotions can be expressed differently across cultures? Paul Ekman shows some emotions are universal, but recognizing cultural differences matters because people can display and interpret emotions in different ways across cultures. Misunderstanding these differences can lead to miscommunication or incorrect judgments about others’ feelings or intentions
