First, its main goal was to remind the student of the components of soil. Rock, clay, silt, sand, and humus. It was also meant to remind the student of the purpose of soil. These were things that were on the study guide for my daughter's test, and therefore deemed important knowledge.
Secondly, it doesn't talk down, and is not overly didactic. It uses a bit of whimsical humor to keep interest, and then slips in the required information.
Also, it doesn't try to pack too much information into one song. This is a very subjective thing, but the problem one encounters if a song is too densely packed with information is that the options for making things aesthetically pleasing become far fewer, and the information can also get lost in the clutter. One should not expect too much of a song, after all.
There are other things I could say about this video, but I'll let you judge for yourself. By a certain standard, this is the song that started it all:
Lyrics after the jump:
When you think of soil,
You might think "dirty"
But flowers are purty,
And they grow in soil.
When you think of soil
You might think "grimy"
But trees are climby,
And they grow in soil.
Soil provides the nutrients plants need to live and grow.
It's made of rock, clay, silt, and sand and humus, don't you know.
Well if you touch soil,
You might think "scummy"
But beets are yummy
And they grow in soil.
And flowers are purty,
And they grow in soil.
And trees are climby,
And they grow in soil.
