For example, we divided our lesson on the solar system into three sections. First was the main lesson where we talked about what exists in a solar system and how many planets are in our solar system. The next section or station was the eclipse experiment while the other was the worksheet about the eclipse. The worksheet would best cover the whole topic instead of just the eclipse.
A way to keep the kids that ends early or is waiting for their turn through the sections, it is best to have an exercise like a math quiz. In our case, we had another worksheet where the kids had to fill out the lunar cycle on how the moon looked like from the Earth in a certain positions. It basically teaches the kids when does the moon is crescent, when it is full or when it is a new moon.
The number of facis play a big part in making this method a success. First, there must be a faci for each group. Each section must have one core faci that best explains the lesson taught in that section. This way, the faci that leads the group only teaches the exercise as they wait their turn and would also add to what the kids learn after each section.
