Spin art, simple homemade device /////Homemade Science with Bruce yeany
 
03:45
This simple device has seen a lot of use and is very popular with students. We use it as an example when exploring the concept of centrifugal force. There are several good demonstrations showing this concept, however,this centrifugal force can be misleading since it is not a real force. It is suggested that a good lesson accompany the use of these devices, otherwise students may end up with misconceptions of what is observed. Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylvania. I am currently in my 38th year of teaching. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself.. I also share and show some of these ideas at workshops, science conferences, or inservice presentations. Videos are shot with a Casio EXH20. Slow motion shots are either 3.5 or 7 times slower.

Cups and ball Centrifugal Force Experiment
 
02:44
Cup Centrifugal Force Experiment Now the object of this experiment is to separate the two balls – put one ball in each glass, this would seem tough. But just place the glasses on a table and spin them! The balls will be separated. The spinning glasses will make the balls fly towards the extreme ends. When you swing an object around on a string or rope, the object will pull outward on the string. This is called the centrifugal force and is caused by the inertia of the object, where it seeks to follow a straight-line path. It is also called an inertial force. The centrifugal force is equal and opposite to the centripetal force that acts on the object, causing it to move in a curved line. Applications of centrifugal force include a rotating disk and water in a swinging bucket. The equation for the centrifugal force is similar to that for centripetal force. This centripetal (center seeking) force actually points toward the center of the circle, but a roller coaster rider experiences(feels) the sensation of a centrifugal force, a pseudo force pushing them toward the outer edge of the car. This sensation is actually the result of the rider's inertia.

Tinker Crate sent him a replacement Spin Art Machine after they learned his brother destroyed the first one. They also asked him to film the actual assembly of this one. Please LIKE and SUBSCRIBE! Joe will have multiple videos and we will try to post weekly videos of fun and exciting adventures. Some of Joe's favorite YouTubers are What's Inside, Dan TDM, Unspeakable, The Sharers and J House Vlogs. Joe is 8 years old and has Autism so he is very inquisitive and whats to know how everything works. FOLLOW JOE'S FUN LAB Facebook: https://www.facebook.com/joesfunlab/ Instagram: https://www.instagram.com/joesfunlab/ Twitter: https://twitter.com/JoesFunLab1 Snapchat: Coming Soon Joe's Fun Lab showing us how the Spin Art Machine works. This video does not include the building of the machine as that is video #3. Accoding to KIDDLE (The Kids Encyclopedia) In physics, centrifugal force (from Latin centrum "center" and fugere "to flee") is a fictitious force that appears when describing physics in a rotating reference frame; it acts on anything with mass considered in such a frame. Centrifugal force is fictitious because although it may feel to a person like a certain force is being exerted on them, someone outside the scene will see something different. Example: If John is in a car that takes a sharp right turn, he will feel as though he is being pushed to his left. This is an imaginary force, called a centrifugal force, or a "running away from the center" force. John feels it because he is inside the car and is affected by it. However, if John's friend, Andy, is on the side of the road facing the front of John's car and watches John's car take a sharp right turn, Andy will see the car push John to the right with the car as it changes direction. This is a real force called centripetal force (or an "aiming towards the center" force) and acts towards the center of the circle of rotation. In other words, John's body, traveling in a straight line before the car turned, wanted to keep moving in a straight line because it had momentum in that direction, but the car, which was exerting a force on John by turning, is pulling him to the right. John feels like his body is being pushed to the left as the car turns, but in fact, his body is being pulled to the right by the turning car. This is a problem that appears in rotating situations. There is a difference between what appears to be happening if watched from the outside or if the event was seen from within a rotating object. These differing viewpoints are called frames of reference. Despite the name, fictitious forces are experienced as very real by anyone whose immediate environment is a non-inertial frame. Even for observers in an inertial frame, fictitious forces provide a natural way to discuss dynamics within rotating environments such as planets, centrifuges, carousels, turning cars, and spinning buckets.

Spin Art 5 Side By Side Paint Comparison
 
24:55
The other day at A.C. Moore, I was shopping for craft paint, and I noticed a brand I was unfamiliar with -- Nicole's Craft Studio Acrylic Craft Paint. And it was on sale, 3 for $1. Three for a dollar! Wow! There was a very nice lady working there, and I talked with her for a moment, asking her about Nicole's. Her assessment was that it was the quality of a generic or store brand. I debated a moment, then decided to go for it. I figured I could do a video testing the paint side-by-side with CraftSmart, and besides, three for a dollar! How could I miss? This video shows my side-by-side test. It's not perfect -- I was out of CraftSmart bright yellow (part of the reason I went to the craft store to begin with) so I substituted light yellow; I was out of CraftSmart dark brown, so I used Apple Barrel chocolate; I didn't measure amounts, so the colors may not have been even in the various pours; didn't use a timer to control the length of each spin. (Wow, I thought I did a better job of controlling for all the variables!) But I used playing cards for the whole test; started each card with a layer of very light yellow, slightly watered down, as a lubricant, to help the paints move smoothly across the cards; stirred each cup of paints just before pouring. Here's the list of paints I used: "Lubricant" paint Nicole's White Nicole's Bright Yellow small amount of water Group 1 Nicole's Neon Blue Nicole's Admiral Nicole's Bright Yellow CraftSmart Neon Blue CraftSmart Dark Blue CraftSmart Light Yellow Group 2 Nicole's Admiral Nicole's Neon Pink Nicole's White CraftSmart Dark Blue CraftSmart Neon Pink CraftSmart White Group 3 Nicole's Bittersweet Chocolate Nicole's Neon Orange Nicole's Bright Yellow Apple Barrel Chocolate CraftSmart Neon Orange CraftSmart Light Yellow The playing cards I use are Casino Royale by Cartamundi, casino quality, linen finish. They curl a little when the paint is wet, but flatten out quickly once dry, and often show a bit of canvas-type texture through the paint, which I really like. I'm sorry the video is a little glitchy in a few places. I need to figure out why it's doing that. Hope you like it! Follow me on Facebook! https://www.facebook.com/LoriPeace9Art/

Thanks for watching! I actually had an early version of this ready last week. Which you can watch here on my second channel: https://www.youtube.com/watch?v=x9B0xCm87xI I decided, with the help of my Patreon supporters, that it wasn't good enough. Have a few ideas for my next video. Space X is winning right now. What do you think? I may try to work on two videos at once this week. Woops forgot the math: The equation is a=(w^2)*r where a is the acceleration, w is the angular velocity and r is the radius. First we must convert RPM to radians per second. There is 2(pi) radians per revolution and 60 seconds in a minute. So one RPM equals 2(pi)/60. We then simply enter these values into the equation. For our first calculation on space station v we get a=(0.1047)^2*150=1.65 ms^-2 Patreon: https://www.patreon.com/user?u=2825050&ty=h Facebook: http://facebook.com/realengineering1 Instagram: https://www.instagram.com/brianjamesmcmanus Twitter: https://twitter.com/Fiosracht Once again thanks to Bensound.com for the amazing royalty free music.

Toy Physics - Looping Pendulum /// Homemade Science with Bruce Yeany
 
04:00
This is a simple demonstration that can be used to impress your friends using a variety of materials. It also can make a nice investigation for a science fair project or a classroom demonstration. Students can test variables and determine the conditions for the best results. The use of small lights and a camera can help capture the beauty in the movement of the small weight as it arrests the movement of the larger weight as it falls. Or, one other use can be for amusement purposes by turning the demonstration into a game. One final note, the spiral path recorded in the pictures was described as an Archimedes spiral, it is actually an involute spiral. While they are very similar, there are subtile differences that can be explained and demonstrated by searching for definitions of these terms. Sorry for the mistake.

Paper Saw Blades- paper cuts paper- Part 1- centrifugal force  //  Homemade Science with Bruce Yeany
 
06:47
Part one: Can a saw blade made out paper cut through a sheet paper? It can if it's spinning fast enough. Circles of paper are mounted onto a Dremel type tool and then are tested to see if they can cut paper, cardboard foam cups, even thin strips of wood. However, don't look to replace your steel saw blades with these anytime soon, these will disintegrate after a few uses, after all, they are just paper. The demonstration relies on the concept referred to as "centrifugal force". I would point out that this is a fictitious force. The behavior that it describes is real enough, however the words defining it are incorrect. the term "force" used with the word centrifugal is misleading and wrong, there is no force applied radially outwards. However, even though it is mislabeled, the term centrifugal force is used to describe the motion of the matter or an object moving radially outwards. This is what we observe here when the paper straightens out when spinning or the string on a grass trimmer becomes rigid as it spins and can be seen in all sorts of other examples and applications all well. It can be as simple as soaking a towel with water and spinning it over your head. The water drops move away from the towel outwards from the center of rotation ( centrifugal force). We can actually see similar results in the paint trails in the pictures at the endo of my spin art video. https://www.youtube.com/watch?v=FF0U7YIwm4M My preference would be to call it a centrifugal behavior. What we are seeing is a cause and effect. The centripetal force which causes the object to curve off of a straight is applied inwards towards the center of rotation. This inward force pulls against the inertia of the object and the effect or result is an outward movement even though there is no outward force. One further note on safety: I recognize that using the table saw without the guard down is dangerous, it was left up for visual purposes of making the video. My standard procedure is normally to use all safety measures available when using power tools. Also, as has been suggested, I would very strongly recommend that anyone attempting this experiment wear gloves as protection against paper cuts.

Sand pendulums are an easy and beautiful method for students of all ages to learn a bit about the harmonic motion. These devices are easy to build and can be adjusted to give a variety of patterns. A pendulum that begins with two point of support can alter the periods of the pendulum as it moves on two perpendicular axis at the same time. The video gives simple instructions on the materials needed and how to adjust the configuration to vary the design. Note on comments: I appreciate seeing comments positive or negative, and learn from helpful criticism. However, I am a middle school teacher and many of my students visit this site, I will remove comments that I feel are offensive or inappropriate. Opening Music: Runaways by Silent Partner

Spinning glitter Mystery ////Homemade Science with Bruce Yeany

The spinning glitter mystery or as it was formerly called , the spinning glitter paradox ( it's not really a paradox ) is a simple experiment that I show to my middle school science students, and then ask them to try it for themselves. A simple version can be repeated in flat bottomed glass or plastic containers using one color of glitter or sand. Why does the material settle at different places as the water and bottle is rotated or spin two different ways? I have my own ideas but would like to hear from others in the comments section.

Student Horsepower Lab Activity  // Homemade Science with Bruce Yeany
 
06:03
This student lab activity is on calculating human horsepower by using data from walking, jogging, and running up a staircase. Student calculations depended on three measurements. 1.The amount of applied force, in this case they were lifting their own body weight. 2. The displacement or distance that the force is applied, this was measured as the height of the staircase from the bottom step up to the top step. 3. The amount of time needed to run from the bottom to the top, measured in seconds. According to their calculations, students were able to generate a range of about 0.2 horsepower to over one horsepower for a very brief moment of time. The idea of horsepower as the effort of measuring work done in an amount of time is credited to James Watt. It is said that his interest was in part to help better describe the abilities of his steam engine by comparing it to the capabilities of the common workhorse. While this measurement is the amount of work that a horse can do over long periods of time, humans on the other hand are only capable of exerting 1 to 3 horsepower in very short bursts. People are capable of exerting about 1/10 horsepower for long periods of time.

Swing vertically or horizontally or a combination of both and the water remains in the cup to the "centrifugal force" acting on the cup.

I also share and show some of these ideas at workshops, science conferences, or inservice presentations.

Physics of toys -string racer/ string rocket //  Homemade Science with Bruce Yeany
 
05:39
The String Racers are rubber band powered toys that are fairly easy to build either at home or in the classroom. Materials are easy to work with and readily available, we have even been successful making our own propellors. I've had students design and build their own variations to try and improve them for distance or speed. Some other variations or challenges in design included using two propellors either side by side or at both ends, getting the racer to loop as it travels down the string or getting it to drop a marble onto a designated target. They have been a lot of fun and can be used as examples in various science principles such as potential to kinetic energy, Newtons laws of motion, measuring speed and other basic concepts.

Magdeburg Hemispheres- amazing alternate method- no pump // Homemade Science with Bruce Yeany
 
05:04
This Magdeburg Hemisphere is a popular demonstration of atmospheric pressure that usually requires a vacuum pump to remove the air from inside the sphere. A more impressive method that is simpler and less expensive can be to use a long plastic tube and a bucket of water. The weight of water inside a long narrow tube attached to the hemispheres will decrease the pressure inside as it is lifted higher and higher. As the pressure decreases inside, the atmospheric pressure outside will require a sizable amount of force to pull the hemispheres apart.

Lever Larry toys are fun to play with and are examples of first class levers. A squeeze of the handle causes an acrobat to swing around as the string supporting him twists and untwists. Slow motion clips are shot 7 times slower The chaotic pendulum is used in my classroom in our discussions of resonance, harmonic motion and chaotic motion. With small amounts of energy, it's movement is predictable, but more energy is added the movement of the arms become unpredictable.

Angle of repose…Physics of toys  //  Homemade Science with Bruce Yeany
 
04:47
The angle of repose or critical angle of repose is how steep various types of materials can be piled without slumping. The steepness of the side of a pile is determined by the amount of friction between the particles of matter. This can vary according to size and density of the material, particles size, smoothness of the particles, whether it is wet or dry, and any cohesive properties of the matter. Materials such as sand piles, dirt, sugar, flour, stones and every other type of loose matter will all exhibit this property. Here are a couple of devices that were made for demonstrating this process using sand without it making a mess.

Fan Cart - Blowing into your own Sail- part 1 // Homemade Science with Bruce Yeany
 
09:15
Here is a reexamination of the fan cart and the popular demonstration of what would happen if you try to blow into your own sail. The misapplication of Newton's 3rd law as used in a children’s storybook and why it is wrong are shown along with some other variation suggested by viewers are tested in this latest video on the fan cart. I have intentionally tried to keep it’s explanation in simple terms for younger students since there are several higher level explanations already available from a variety of sources on the internet and here on youtube. Note on comments: I appreciate seeing comments positive or negative, and learn from helpful criticism. However, I am a middle school teacher and many of my students visit this site, I will remove comments that I feel are offensive or inappropriate.

Bicycle tuning  fork - physics of toys // Homemade Science with Bruce Yeany
 
04:14
The front fork off of a bicycle makes a nice addition to a tuning fork set. The frequency of this one is very low, about 54 Hz (vibrations per second). The sound of fork is very deep and the camera does not do a good job of picking it up but otherwise, it makes for an interesting piece of equipment. My students have found it to be entertaining to hold it against various surfaces, and in doing so it can be heard in other classrooms adjacent to mine.
