The Maple Leaf Learning Playhouse
Hey guys, today we're going to do an experiment.
Yeah, so please print out your paper and let's
get started okay? Yeah First you need soy sauce, vinegar, salt, ketchup and lemons.
Yeah! And you also need some small dishes like this to put the liquids
into okay. And lastly we need some coins. In Japan I will use these ten yen coins
but in Canada or America you can use pennies okay, yeah! Any copper coin is
Any copper coin is fine as long as it's really dirty okay, yeah! Well, write your name and let's get
started okay? Great we'll start with ketchup
Just dip half the coin into the ketchup okay because we want to see what it
looked like before and would it look like after, okay?
Yeah! Hold the coin in the ketchup for about a minute
Hey, don't eat it!
Now, after a minute wash off your coin and you can see the difference.
What the coin looked like before and what it looks like now!
It's quite a big difference you know.
Then tape your coin onto your graph and try the next solution, okay? Yeah!
Gee, I wonder which one cleans the coins the best? Actually I know the answer but I'm
not going to tell you now. I want you to try the experiment, okay?
But if you really really want to know the answer will tell you at the end okay but please
try the experiment yourself okay? It's a lot of fun and you can learn a lot. Well,
thank you so much for hanging out. See you soon, goodbye!
