Build your own Wave Machine - this is a great physics demonstration for the classroom or at home as a brilliant science experiment for kids.
This science demonstration video is one of over 8,000 free teaching resources available for from the National STEM Centre following registration. Register here www.nationalstemcentre.org.uk...
The Wave Machine is also a fun and useful tool for the science classroom as it can be used to demonstrate transverse wave motion and is a great way of demonstrating how light waves change when moving through different media such as glass and air.

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.

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😊

@JonathanSanderson 7 жыл бұрын

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 Жыл бұрын

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

@JonathanSanderson Жыл бұрын

@@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!

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?
