Contrasting Pairs

I was reading a photography book the other day (see footer) and it described an exercise that I want to do to try and better my photography skillz.

Some background
It's an exercise by Johannes Itten, who ran the "preliminary course" to teach students the basics of material characteristics, composition, and colour at the Bauhaus in Germany in the 1920s. His theory of composition was rooted in one simple concept: contrasts. One of the first exercises he would set his students was to discover and illustrate the different possibilities of contrast. Of course, these were art exercises - and given that I'm an artist as well as a photographer, I could have done them like that - but this was in a photography book and I want to do the photography exercise.

The project itself
The project is in two parts. The first (the easy part) is to produce pairs of photographs that contrast with each other - either ones you've already taken or new ones. I'll be doing a mixture (probably mostly new).

The second part is to combine the two poles of the contrast in one photo. This obviously requires more

but I do like a challenge

You're also supposed to approach the contrasts from three directions, or, as Itten said, "[you have] to experience them with [your] senses, objectivize them intellectually, and realise them synthetically."
i.e.
get a feeling for the contrast first WITHOUT thinking of it as an image
then list the ways of putting this sensation across
finally, make a picture
I am not sure how well I'll do with that part.

The list
From Itten's original Bauhaus exercise:
Point/line
Area/line
Plane/volume
Area/body
Line/body
Large/small
High/low
Smooth/rough
Long/short
Hard/soft
Broad/narrow
Still/moving
Thick/thin
Light/heavy
Light/dark
Transparent/opaque
Black/white
Continuous/intermittent
Much/little
Liquid/solid
Straight/curved
Sweet/sour
Pointed/blunt
Strong/weak
Horizontal/vertical
Loud/soft
Diagonal/circular

A couple of others I might do coz I have an idea for them:
Dirty/clean

Help?
If anyone has any ideas about "continuous/intermittent" (either as two photos or as one photo) please tell me as I am stumped on that one!
