Wave Machine Demonstration

[@mickibrown4392]

This was a great demonstration that I showed my sixth grade students. I had each class work cooperatively to construct one model per class. All five classes successfully constructed and practiced making longitudinal waves. The model helped them understand the transfer of energy through surface water waves. Thank you for the idea and a hands-on way to reinforce the concept.

[@shantiejagnarine2339]

I like your project it was awesome. I did it for a Science Fair and i got a A+. Thank you

EXCELLENT MODEL. Ive been trying to ficgure out how to create an inexpensive version of the more "professional version/lab grade" for a while now. Shows nearly everything Id like to show about energy traveling through media:) You should make a vid to demo how to use it to show constructive and destructive intereference;)!

Great model and explanation, helps me a lot. Thanks!

[@SharmajiIAS]

Really the most elegant science demo ... Inspiring

[@johnhaddox8224]

Great activity for Physics or Earth Science. You can also demonstrate longitudinal waves by tapping down on the end. Students will observe that longitudinal waves move faster than transverse waves, analogous to comparing P waves and S waves.

[@stevenhuffman3415]

my class did it and loved it and they said it taisted good so if your looking for a wave lesson plan this is the way to go

[@stardust3219]

This is an excellent demonstration to help students develop an intuition about waves and their propagation.

[@maraleescott9287]

This is an awesome activity that makes wave movement visible. We can not use food in our classrooms so I am replacing the gummies with small pieces of clay. I'd like to hear what others are using instead of the candy.

[@janelush8408]

I have the same issue - I am going to try next week using wooden clothes pegs (the kind with the spring in them). Then I can adjust their position quite easily. I was thinking pieces of clay might be difficult because you'd want them to be uniform mass. How did you get on?

So one of cool things for a more advanced discussion is: what happens at the bound between fast an slow waves? There has to be reflection, not just transmission.

I presume you've seen the black & white AT&T archive material that shows a guy using a similar setup. I wonder if anyone noticed the reflection from the discontinuity you introduced.

[@josephrousseau1946]

When you remove mass the speed of the wave increases, is there an impact upon the amplitude of the wave, or does the amplitude remain constant as it travels from the sticks with candy through the sticks with no candy?

[@caseymygrant1481]

I'm trying to figure out how to incorporate collecting data and putting math into this. I'm thinking of having stop watches for groups to see the different time of the waves, but I don't know how to do this. We've studied electricity, magnetism, light, sound, and are moving onto plate tectonics so I want to tie it neatly together. Any pointers?

[@PacoOtis]

Very clever and well done! Thanks! You might have even further benefits if you could lace the jelly babies with salt peter and a birth control substance! The students might then pay further attention! Best of luck mate!

[@crashsitetube]

This is a classic example of thinking you're doing the "S" of "STEM" when you're really doing the "E" to make the "T". Others, would do the "M" to do the "E" to do the "T". In any case, the "S" is missing. What forces are at work that produce the force differentials that provide the impetus to make the different parts of the 'machine' move as they do? So, what you have in this video is a mobile that looks pretty and might be tasty but, does it do any more 'science' than you'd get by looking at and listening to a wind chime?

[@Marthasterias]

Awesome im off down the shops!

[@RealityTrailers]

Interesting. So it's really the candy that keeps the children's attention span locked onto the wave device. How else would they pay any attention to such unless it's a cell phone with a new and amazing app?

Hello , I'm trying to help my daughter with a second grade science project. I feel like we found a great project idea just having a bit of an issue on how to keep it in a way that compliments her age group. What would be a good question to ask for a second grade science fair project using the gummy bear wave machine in regards to sound? What kind of graphs could my second grader make? I was thinking to measure how fast the wave comes back to the starting point when we add energy to the wave machine. Repeat this procedure 5 times taking 5 gummies off each time until i reach the mid point of the gummy wave machine. Thank you in advance😊

I love that he tries to stop it after the wave has already passed him and by the time he lets go the wave comes back and he tries to stop it again incorrectly.

[@industrialdonut7681]

Acidic Apples how should he stop it then? by creating an opposite wave or something?

[@Jokestur]

No, just waiting for the energy of the wave to be transferred into his hand instead of moving his hand away before they get the chance. (But yeah, that would work too if you were genuinely wondering)

[@industrialdonut7681]

Acidic Apples oh lol I see what you mean his wave machine is just 2 quick 4 him

[@thomaschen1365]

an awesome demonstration

[@industrialdonut7681]

SUCH A GOOD VIDEO! So does this mean, as I've been speculating all day now, that waves in the ocean all travel at the same velocity because they're all in the same medium?! just like how the speed of sound is constant per given air densities!!??

[@michaelmcpartlin1033]

The ocean, while all water, has different temperatures, salt densities, and composition. This can cause changes in wave speed. While small, it would be inaccurate to say waves travel at the same speed in ALL water.

Do a standing wave please

[@rabbitpiet7182]

[@prof.kadulandert8043]

It was very good, the best I saw here on KZbin, congratulations. What is the distance between the toothpicks? Did you use glue to attach the toothpicks or put them directly on the tape? Thank you.

[@JonathanSanderson]

The kebab skewers are about 5cm apart - the separation does affect wave speed by changing the mass per unit length, but in practice you don't have to be too accurate. We usually line them up by eye. They're stuck directly onto the tape. Most people then put another layer of tape to sandwich the sticks, which also helps the apparatus last a bit longer, but it's not really necessary and it can change the behaviour of the tape as a torsion spring. So I never bother.

[@markchesterdelacruz4542]

@@JonathanSanderson What type of tape is needed for this experiment?

[@JonathanSanderson]

@@markchesterdelacruz4542 In the UK we typically call it 'Gaffer tape', I don't know if that's common internationally. This stuff: en.wikipedia.org/wiki/Gaffer_tape. In practice most brands of wide cloth-ish tape work well, as does duct tape. Elephant and Duck brands are good, but so are many others. Some of the non-branded tapes aren't very sticky and would definitely benefit from a facing layer; it's one of those situations where it's probably worth buying the better tape in the first place. One thing I've never tried is to splice from one brand/type/weight/width of tape to another, while keeping the stick pitch and sweet mass the same. With a bit of faffing about I suspect you could find combinations where the wave speed clearly changes with the medium. Other commenters have noted that you can sometimes observe reflection at interfaces, eg. where you remove half the sticks. I haven't noticed anyone comment that if you send a pulse down a long tape you can observe wavepacket dispersion. I suspect you could even measure it, which might be fun. In 30 years of demo wrangling, this is still the one of which I'm most proud!
