Friction For Children - 4 Tricks to Help Children Understand Friction

If you're looking for ways to aid in teaching friction for children then keep reading. So your child comes home from school with questions about friction. How can you help your child understand this concept? Without friction life as we know it would not exist. Every surface would be more slippery than ice. You could not walk, run, write, or even feed yourself without friction. Friction for children is as easy as using common examples to guide your explanation.

Friction for children starts with the basics. Friction is a push, pull, or a force which works against the motion of objects that are in contact as they move past each other. When objects are touching their surfaces tend to stick together, like the tiny loops and hooks of Velcro. Heat and sound are also produced by friction. If you rub the palms of your hands together quickly your hands get warm and you can hear the sound that friction creates.

There are three types of friction; sliding friction, rolling friction, and fluid friction. Sliding friction is caused by two objects touching each other that slide past one another. For example, when you push a large wooden crate across a floor you push against sliding friction. The entire surface of the crate that is in contact with the floor slides against the floor, slowing down the motion of the crate. Rolling friction uses wheels. If you move the identical large wooden crate with a wagon then you exert a force against rolling friction. Only the bottom of each wheel is in contact with the floor. Rolling friction is less than sliding friction; it takes less effort to push the crate on the wagon than to push the crate that is directly resting on the floor. When an object is in contact with a fluid, a liquid or a gas this is considered fluid friction. Airplanes and race cars are streamlined to reduce fluid friction. They have smooth, curved surfaces to reduce the friction, called drag, with the air.

When teaching friction for children it's important to stress how friction can be advantageous. You light a match using friction. As you strike a match, friction creates enough heat to ignite a chemical compound in the match head that then burns the rest of the match head. Automobile brakes work because of friction. As the brake pads rub against the car's wheels, the car slows down. Shoes designed for some sports have special soles to use friction to your advantage. Baseball shoes and football shoes have cleats to increase friction by sticking to cracks in the ground. A violinist puts rosin on his bow to increase friction between the bow and the violin strings, therefore producing sound.

However, friction can also be disadvantageous. If a door hinge squeaks, the noise is caused by friction. The space shuttle's nose and wings heat up dramatically as it returns to Earth from orbit. The ceramic tiles on the shuttle's nose and wings are designed to dissipate this heat caused by friction. The moving parts of a car's engine rub against each other and can stick together, causing the engine to seize and to stop working. Using oil in a car's engine protects the parts from friction. Cooked foods tend to stick to pans. Teflon on non-stick cookware reduces friction between the food and the pan, causing the food to slide. Competitive swimmers wear specially designed racing suits to reduce the friction between themselves and the water so that they can swim faster. A bowler wears extremely flat-soled shoes to slide on the lane right before he releases the bowling ball. Silicone aerosols, oils, grease, graphite (the very soft form of carbon in "lead" pencils), and ball bearings are all used to reduce friction.

By using every day examples, you can teach friction for children and help them better understand this concept. The three types of friction, sliding, rolling and fluid, can either be beneficial or detrimental to the motion of objects. Friction between your pen or pencil tip and the paper you write on allows you to write on the paper. Friction between the ground or the floor and your feet allows you to run or walk along these surfaces. Friction between your food and a spoon or fork allows you to eat with these utensils.

The Value of Losing

Congratulations to the Pittsburgh Steelers who won the Super Bowl and became champions of the world for a record tying 5th time.

It must have been great to hoist the Lombardi Trophy as the hapless Seahawks looked on in defeat. What a bunch of losers falling flat on their face like a baby first learning to walk. Of course, they did finish 2nd best - ahead of the other 30 losing teams that didn't even win their conference. While some may consider the NFC champs to have had a successful season, Tom Seaver once wrote: "there are only two places an athlete can finish - first place and no place". How about Vince Lombardi who said: "Show me a good loser and I'll show you a loser". Even in the world sports, where it really is about winning, or in life, this can't be the way we think. As a looking glass into real life, when 31 NFL teams, representing the best players in the world, are all looking up at the Champion Steelers, we all need to find and understand the value of losing.

Everybody Loses

The Value of Losing

While being a loser requires that you lose, the corollary that losing makes you a loser is certainly false. Vince Lombardi is known as one of the greatest and most intense coaches in history. Of course, most of us know Coach Lombardi's famous quote: "Winning isn't everything; it's the only thing". While he always put that kind of emphasis on winning, most of us don't know that he also said: "If you can't accept losing, you can't win." While we all like to win much more than we like to lose, in order to play and be a part of something greater, we have to be willing to take the risk that we might lose. It has to be accepted that losing is a natural a part of participating and of winning.

Why It's Okay to Lose

While not necessarily intuitive, there are many reasons why we can feel good about losing and I want to focus on two of these: the first and most obvious reason to lose is because it will help us to win; the second reason to lose is that it helps us to win in life.

Losing creates opportunity. Every loss has more lessons about what a team or individual can do to improve than any win. Losing also provides more motivation. Winning tends to cause people to overlook errors in judgment and fundamentals that only losing can reveal. It's through the process that individuals and teams can discern areas to work on through practice to improve. Maybe even more important is that losing forces people to recognize that they want to win. The motivation provided by losing is a key to helping teams work harder in practice to improve and to play harder to win. Coach John Wooden's Pyramid of Success (January, 2006) emphasizes that success isn't winning or losing, but the self satisfaction derived from doing your best to be the best of which you are capable. Both winning and losing should inspire an individual to improve and to maximize their potential. By using losses in this way, we can motivate ourselves and others.

We can also use these lessons to improve other aspects of our life because losing is as much a part of every day life as it is a natural experience of playing sports. As parents, we make such an effort to help our kids feel better and to not let them experience failures. Ultimately, by not acknowledging their shortcomings, mistakes and losses, we don't allow them to live up to their potential. Failing is natural and it creates motivation. Without failing, kids may not see the need to work harder to improve. Telling kids that they have a "good eye" when the pitch is over the backstop, or saying "nice try" after a mistake may seem encouraging. However, we should also understand that it can be fine to let them know that a mistake has been made. When an error is made we can acknowledge it and then work to learn from the mistake and ultimately to improve.

By continuing to tell kids that they're always doing great sends a message that they don't need to work as hard. Kids are smart and they realize when they're good or bad. Sometimes they need to be protected but other times we need to also be honest if we want them to succeed in life. The idea that a person just needs to do their best isn't always true - sometimes they need to do even better. I heard of story of an employee who responded to a new work assignment for a project that needed to be done by a deadline with: "I'll do my best". Well, in this case, it just needed to get done and failing to finish it, even if that was their "best effort", was simply unacceptable. Sometimes, a person's best is not enough and you need to "get it done". This is one of the lessons that you can learn by losing because it is part of life.

Conclusion

Bud Wilkerson, the famous Okalahoma Sooners football coach who led his team on a 47 game winning streak, noted that the only way you could meet somebody that never lost meant that you had to find somebody that never played the game. While nobody wants to lose, we can use losing to motivate and improve. We can also extrapolate the lessons of losing to the greater life lessons so that we can all become the best of which we are capable. Losing is part of everything we do and has tremendous value. Mistakes are a natural part of participating so we shouldn't be afraid of acknowledging our errors and using them to improve. Our goal, in youth sports and in life, has to be to see the value of losing and use it to become better athletes, parents and people.
