![]() Many students will agree that the force of air resistance on a moving object depends on the speed of the object. Factors suggested by students might include shape, mass, speed, or position or orientation of the object. Ask students what factors determine the extent to which air resistance affects the movement of a moving object. The warm-up activities with the paper and the book, the coin and the feather, and the video of Commander Scott dropping a hammer and a feather on the moon all demonstrate that the difference in the rate of falling objects depends more on the effects of air resistance than on the rate at which gravity accelerates falling objects. Galileo’s actual experiments involved rolling spheres with different masses down a long incline in order to slow their motion and allow him to record data for his calculations. It is not clear if that story is true, but it is known that Galileo did perform experiments to show that falling objects, regardless of mass, accelerate toward Earth at the same rate. Several hundred years before Commander Scott performed his experiment on the moon, Italian physicist and mathematician Galileo Galilei supposedly dropped 2 cannon balls of different masses from the Leaning Tower of Pisa to prove that they would fall at the same rate. If someone on the surface of Earth dropped a hammer and a feather from the same height at the same time, the hammer would tend to fall faster, landing sooner on the ground.Ī much earlier experiment is said to have happened in the 16th century. This event seems to contradict experience. A quick Internet search will turn up footage of Commander Scott dropping a hammer and a feather simultaneously on the surface of the moon. In 1971 David Scott, an astronaut on the Apollo 15 mission, performed an experiment while standing on the moon. This time the coin and the feather fall at the same rate, landing on the bottom end of the tube at the same time.Īnother warm-up activity for a lesson in air resistance might include a review of some famous experiments involving falling objects. Once a vacuum is created inside the tube, close the valve and repeat the experiment. A valve on 1 end of the tube allows you to remove the air in the tube with a vacuum pump. The coin falls from 1 end of the tube to the other, while the feather floats slowly down. Hold the tube upright and then invert it. In this demonstration you place a coin and a feather in a long, clear tube. Then drop the 2 objects together and they should fall at the same rate.Īnother standard demonstration in air resistance is the coin and feather. Repeat the experiment, first placing the paper on top of the book so that the paper is shielded from the air by the book. If the book and the paper are held separately and dropped, this will be the case. Many students will likely select the book. Hold up both objects and ask students which will fall to the floor faster. ![]() One common demonstration of air resistance involves observing a piece of paper and a heavy book as they fall. Introductory-level physics courses often use situations with ideal conditions to introduce students to the fundamentals of mechanics, and air resistance is included in later courses.Īir resistance is an important concept for students to understand, and there are some simple demonstrations and activities that allow students to investigate the effects of drag on moving objects. One reason is because calculations that involve air resistance can be challenging. ![]() However, in most first-year physics classes, air resistance is ignored. The trajectory of projectiles, the velocity of falling objects, and the design of modern vehicles are just a few instances where air resistance affects the movement of an object.

Many models are found to use “unhealthy means” to lose weight and a lot of them are classified as underweight for their age and height. It’s not a business I want to be involved in.”Ī 2017 study conducted by Harvard and Northeastern University found that 62% of models were told by their agencies to lose weight. “However, I don’t aspire to do any modeling anymore. The clients also apologized multiple times to forgive him for what he said, he told the clients he is very sorry and I believe him,” she said. “I could see on his face he did not expect this.”Īccording to the replies on TikTok, the photographer has since been fired from working with the brand. “Telling him off felt so good,” she said. “Thank you for standing up!” one person wrote. Her video has since racked up over 20 million views, with commenters raving about her confidence in standing up to the photographer. “Luckily I recovered, but the comment that the photographer made triggered me.” “I developed an eating disorder because of ,” she said. BIPOC are half as likely to be properly diagnosed or to receive treatment for their eating disorders as white people.īack when did more modeling, she used to get damaging comments about her size all of the time, she explained to In The Know. “You’re not the one to tell me what to do with my body.”Īccording to the National Association of Anorexia Nervosa and Associated Disorders (ANAD), eating disorders cause roughly 10,000 deaths in the U.S. “She can die because of that one comment you made,” adds. “You are very lucky that I am secure in my body and that I love myself - but if there was another model who was standing here and was insecure about her body, that one comment that you made would literally make her go have no words ♬ original sound – Thewizardliz “You can’t tell people to not eat until the next shoot because then they will develop an eating disorder,” tells the photographer in the clip. Right before the shoot was about to start, said the photographer offered her another job in two weeks but added that “it would be best if I didn’t eat so I would look skinnier in the pictures.”Ī video of the interaction, which was recorded by friend and then shared on TikTok, captures the aftermath of the photographer making a comment about her body. “I don’t know a lot about the photographer - it was someone working on an individual basis that the people from the brand hired.” “I took this one job ’cause it was paid,” she explained to In The Know. ![]() Still, she decided to take the job opportunity anyway. She had modeled before but wasn’t really interested in continuing the career. TikTok user said a clothing brand reached out to her over Instagram and said they liked her look. You can overdo it, becoming too deeply involved in other people's lives.A model is garnering praise on TikTok after slamming a photographer for suggesting that she “didn’t eat” for two weeks to “look skinnier” at the next shoot. Your desire to help others is so strong that you often find yourself sacrificing your own personal needs for someone else's. Your love for family and friends is a major source of your happiness and sometimes unhappiness. You love your home and family and work hard to make both comfortable and secure. “Your attention is directed to helping and caring for those you love. ” Inner analysis of Thessa by heart number 6 ![]() Your deepest intention is to transform the world. You are drawn to those who suffer physically or are at the hand of injustice. You have great compassion and seek to create a more humane society. You are extremely idealistic, sometimes to the point of being naive about people or methods. You are attracted to a cause or a movement whose purpose is to make a better world.

Varying the space between the hoops elongates or enlarges the figure eight. I love to use two hoops placed side by side on the floor to provide a visual cue. ![]() The Lazy 8 can also be carried out as a motor activity, having the client walk, skip, or run around a figure eight. It can be used in several different formats – using the eyes, drawing the figure of 8 in the appropriate orientation, and in motion, as we shall see shortly. The repeated action of the Lazy 8 is also very calming. It can be used to improve ocular motor function, which assists with reading, and crossing the mid-line improves integration between the two hemispheres of the brain. In Brain Gym terms, the Lazy 8 turns on or activates the eyes while also crossing the mid-line. One that I use a lot is the Lazy 8 – a figure eight that lies on its side like the infinity sign. Although there is a specific process to follow, many of the exercises are both beneficial and transferable into a regular OT session. I began with Brain Gym I and II and loved the fact that the two trainers in South Africa were experienced occupational therapists trained in both SI and NDT.īrain Gym is wonderful for assisting with goal setting, whole brain learning, stress release, and re-patterning. Little did I know that it would become an integral part of much of my OT practice. This all leads to easier and more pleasurable learning.Īccording to the Brain Gym website, Brain Gym exercises recall the movements naturally done during the first years of life when learning to coordinate the eyes, ears, hands and whole body.I came across Educational Kinesiology in the early 1990s when searching for tools or techniques to help healing from a chronic illness. By doing these movements, and holding or rubbing specific points of the body (the so-called ‘energy points’), you’ll get your energy flowing again – and blockages and tension in the body as well as in the mind will disappear as stress is reduced. They’re all activities and movements that help coordinate the right and left sides of the brain, so the two sides can work together in a balanced way.ĭennison understood that when the right and left sides of the brain and body aren’t coordinated, people might suffer from learning difficulties, poor concentration, dyslexia and ADHD.īrain Gym is helpful to improve coordination and release learning and energy blockages. They include crawling, drawing, tracing symbols in the air, yawning and breathing. Some exercises are for centering, some are for focusing, and some are to correct laterality (right/left) problems. On the premise that learning isn’t an isolated brain function, and that our bodies are as much a part of the learning process as the brain, he concludes, “movement the door to learning”.īrain Gym is a set of 26 simple, powerful activities designed to make it easier for people to relax, focus, practice attentiveness to their surroundings, and control impulses while strengthening the neural connections throughout the entire brain. He calls this experience being ‘switched off’, and created Brain Gym exercises to switch the brain back on and get it working in an integrated way again. Dennsion worked as a public school teacher and reading specialist until he discovered a trend - when children or adults are under stress, certain parts of their brains become less active. The word ‘kinesiology’ means movement and educational kinesiology simply means “learning through movement.”īrain Gym was created in the 1980’s by Dr. “Educational Kinesiology” (or Brain Gym) might be one way to jumpstart your innate curiosity and your natural tendency to learn. So if learning doesn’t feel as effortless for you - maybe it’s time to rediscover the joyride (especially since it’s a process that continues throughout life!). When we get a little older, we can start to forget the joy inherent in learning something new. Observe any infant or toddler and you will be amazed at how quickly and effortlessly they can absorb so much. Is there such a thing as enjoyable learning? We often believe yes, but only sometimes and only for some people.īut shouldn’t learning be always learning fun and easy? After all, it’s a process we take to naturally. ![]() ![]() ![]() We harvest dozens of tomatoes from each plant in our Alabama test garden, where the harvest season lasts two full months and the growing conditions are very good. Compared to other beefsteak types, Big Beef is early and will set fruit reliably even in cool, wet weather. The fruit is borne on vigorous, indeterminate vines from summer until frost. The large fruit has old-time tomato flavor and the vines are resistant to many of the problems that can discourage gardeners. Finally in 1994 those wishes came true with Big Beef. Some gardeners also let the seeds drop to make new plants.Fall is a great time to grow cilantro in mild climates, as the plants are frost tolerant and love the cool weather in fall, winter, and early spring.Organic varieties are only available at retailers.įor years gardeners wanted a large, beefsteak-type tomato that was delicious, early to bear, and highly disease resistant. You can grind the seeds or use them whole. After it blooms, harvest the seeds-they are what you buy in spice jars as coriander, another common ingredient in Asian cooking. Cilantro grows tall and blooms at the end of its life, usually after the weather gets hot. It is a fast-growing annual except in milder climates where it will overwinter. Young leaves have the best flavor, so be sure to harvest often. It grows in a rosette of stemmy leaves that are ready to harvest shortly after planting. Sometimes called Chinese parsley, its distinctive aroma and flavor is also part of Caribbean and Asian foods, lending flavor to recaito, salsas, curries, salads, chutneys, herbed butters, and meat marinades.Cilantro looks like flat leaf Italian parsley, but the leaves are thinner. The leaves have an instantly recognizable fragrance that fills a room when you cut them. If you like the aromatic flavor of salsa served in Mexican restaurants, you'll like cilantro. Jalapeño became the first pepper in space when a bag full of pods accompanied astronauts on the shuttle Columbia in November 1982! Organic varieties are only available at retailers. Use jalapeño on nachos or in salsa, or smoke the mature red ones over mesquite chips to make your own chipotle sauce. The compact plants grow well in containers. Widely adapted, jalapeño plants yield a bountiful harvest in dry or humid, hot or cool climates. If peppers grow fast, get plenty of water, and are harvested soon, they may be milder than peppers that stay on the plant a long time, or that develop slowly and under stressful conditions. Often, the heat of the peppers will vary, even those from the same plant. The skin may show a netting pattern as fruit ages, but it does not affect flavor. Jalapeño produces 3-inch, thick-walled, moderately hot pods with deep green color that matures to a bright red. Named for the town of Jalapa, Mexico, this is the most popular chile pepper in the United States. ![]() |
