Great video and series! We love the archaeology site PB sandwich analogy! Our favorite activity with kids is the M&M chocolate chip cookie excavation. The chocolate chips and M&M's represent different artifacts and the cookie represents the dirt of the site. The goal is to excavate without destroying the artifacts and to map where each artifact found on the cookie grid. When they are finished we have them place the artifacts in categories based on colors and try to explain what was happening at the site. We say it's an activity for kids, but adults love it too!

Raven...What DOES your profile look like on the app for "dating" fossils? Two other questions: Why have people been fundamentally not so bright as to LIVE near volcanoes for ANY amount of time? And...are you saying that Star Trek science is not real????? How about Star Wars? (Whoops! That was 3 more questions!) Disneyland is real and Disneyland has Star Wars stuff.
@DigItWithRaven3 жыл бұрын
Haha my profile is much less exciting than others. Full of old things that no one understands ;). 1. volcanic areas are actually very fertile places and so when they're not spewing, you can grow quite a bit on there! 2. There's a fun Star Trek and archaeology video over on ArchaeoDuck's chanel- go check it out! As to the rest of the science.... I've not watched much of Star Trek so I cannot comment! 3. Star Wars is real.... in all our hearts

How accurate is the argon argon method for recent volcanic eruptions? There was a paper using this method for the eruption of Vesuvius, Italy in AD 79. It was off my a few years. I didn't think it was possible.

But how did you determine the half-life of potassium 40? Has this been determined experimentally? What method did you use to determine the half-life? How is it possible to determine that in this case where you say the half-life is over a billion years? I think it is impossible to create laboratory conditions that could determine that time.

@cskinner01293 жыл бұрын
Amazingly well done. I’ve got a couple questions I always wonder about this topic. How do we know the half-life of 1.5 billion years? Don’t all unstable isotopes have variable, exponential decay rates? Maybe you’ve got another video on this, if so, sorry!
@williamchamberlain22632 жыл бұрын
The exponential curve is the remaining undecayed isotope as it halves in mass at each half-life period Edit: this isn't the best explanation, but... the half-life is an average over a very large number of nuclei decaying; each has a 50/50 chance of decaying in each half-life, but like tossing _a lot_ of coins, roughly half will come up heads/decay each toss/half-life.

You went over this in the video, but for this to be viable we would *need* two eruptions? One on top of the site, but one underneath it too so we know an effective range (in my head I’m thinking “what’s stopping an eruption from happening a while later, but coincidentally in the same area as the site, and then it messes up all your estimates”)? Or do you only need a single sample, and you can just know it will effectively date the site
@DigItWithRaven3 жыл бұрын
For sandwich dating yes two eruptions would be needed! But if more eruptions happen, it will leave a distinctive layer that we can identify and date separately. That's the glory of stratigraphy :)
