Simulation Teaching - Biology

We, PL, Jan and I were in one group for Simulation Teaching for Biology.
We were given the topic - Locomotion of Animals (5th Form in Malaysians' Syllabus).
Well, there are locomotion of Birds, Fishes, Earthworm, Grasshopper to be selected for us to teach within 45mins.
Firstly, we chose Fish and Bird after a few days of investigation on each animals.
Erm, no harm to be honest here, we chose the Fish and Bird due to the easiness for us to teach in several ways and difficulties if we chose Earthworm and Grasshopper.
Well, 3 of us are not Biology students*, but "forced" to teach in Biology.

(* 3 of us take no subject related to Biology in University, only PL who seem to be more expert than us, as she studied Biology in her 6th form, while Jan and I have only studied Biology in 4th and 5th form.)

At last, we come to the decision, where we will only teach Locomotion of Fish as we have only a very little of time. For us, a quality teaching is when our students can learn what we (teachers) have planned. If we put in too many things in a lesson, the students might not able to absorb what we want to teach.
