We can use this simulation about the membrane channels in the first course of Secondary School.
They can explore through this simulation how the particles can move from one side of the membrane to the other. They will search How and Why. In this way they'll understand the transportation inter membrane.
As it is the first course, it must be an easy way for them to understand how the particles go inside the cell trough the membrane transport system.
Playing with this simulation program they will be able to have a better understanding of the transportation mechanism into and out of the cell. They also can predict if a particle is going to go through depending on the type of channel such as leakage channel or gated channels. Also the number of them and the number of particles which go in and out of the cell.
So it's quite a good way for learning several topics: membrane channels, cell membrane and diffusion.
Regarding the frog dissection, it was quite interesting to see how the students was working. In fact, we can apply it to our classes. We already do it with fish or squid.
