Now the students must follow the pattern you have posted for them, and put in their information. You can set your own additional requirements for the assignment as well. You might be surprised with the ideas they come up with. Here is a basic example of what a pantoum would look like based of the weight estimates for other planets.
My earth weight
I'm 19 pounds on the moon
It feels pretty great
I'm still only 129.3 on Neptune.
I'm like a feather on the Moon.
My pounds number 43.3 on Mars
On Neptune, I'd be at my ideal soon
Guess I can afford a few extra candy bars.
On Mars to be 43.3 pounds light
Makes me feel like I've won
Till I take sight
Of the 3,113.2 pounds I could shed on the sun.
Victory on mars seems pretty near
To make my scale say what I need.
I will be happy with myself, and not shed a tear
If anyone dare ask, I am here as I am on Ganymede.
(Ganymede is one of Jupiter's moons).
