This video, “Happy Mole Day To You”, was made to help students remember about mole. I think it is quite clever actually as already I remember that it is 10 to the power of 23, as they celebrate mole day on the 23 rd of October (the tenth month).
It is a fun way to learn about mole by making it into a catchy little song. I have in my head, “how many moles in hydrogen, just use the subscript, the number is 2”. Now I know that, it will help be able to work out others. It also mentions atomic mass and flashes the periodic table with the number flashing indicating atomic weight by the flashing numbers.
It is a good video clip, funny, clever, fun and it is brilliant for those wanting to know about mole but hates reading long pieces of text that are complicated and boring.
This video clip is less informative than the first, however, it is highly catchy and very amusing. It tells you mole is a unit and that it is 6 x 10 to the 23. They try to use examples as to how big that really is by saying if you stack that amount of paper it would reach to the moon and back, and if you had that amount of marshmallows it would be so much it would block out the sun.
This is giving the viewer a small idea of how large the number really is, and as they say, tis to big to comprehend. However, after all that they say if you put some sugar on your hand, you are holding the same amount (6 x 10 to the 23) of atoms in your hand. This gives you an idea of how small atoms are, even if mole is a large number, in terms of atoms it is small.
