This sound like a really interesting competition. Get your kids to Rap about Science! Writing poem, rhymes and songs is a really engaging way for students to remember and understand Science concepts more deeply. In fact, writing a song which has certain parameters and with rhymes is a fantastic tool that helps learners to develop not only Literacy skills, but also thinking. A Rapper often uses his/her wit and humour to get their message across with the interesting way they have to play on words. Transferring this skill to Science is really useful, because it can help learners to represent difficult scientific concepts in a more memorable way and think deeply about the meaning of physical, chemical and biological processes as well as building their own models to consolidate understanding.
A good example is the first verse of this poem written by one of my yr 12 pupils last year:
The photoelectric effect is easy
UV light hits the metal causing it to become a little queasy
The metal releases a photoelectron without a fight
More electrons are released when the intensity is increased of the light
