The 4th experiment was impromptu. They requested to do the yeast experiment and it was not planned in our materials. Well, since we have ready materials, why not? Learn on the go! One of our Sowing Seedz motto. We quickly prepared the materials and set them up. This had to be done on the spot for observation later.
Again, head knowledge tells them they know the one of the balloons would be inflated, but they were not sure why. Hence, we explained that together with sugar, warm water and yeast, respiration took place in the bottle. Yeast is a living thing and the food it need is sugar. We got them to observe the close up on the bubbles (carbon dioxide) and how that gas inflated the balloon.
After getting them to observe, we routed their attention to the celery experiment done the previous lesson. The leaves were a beautiful hue of blue! The xylem (water carrying tubes) were seen clearly as well. More recording was done.
The 5th experiment was also unplanned. We planned to do the Bull’s Eye activity but somehow, one of the boys folded an aeroplane and played with it, giving us the inspiration to do that as well. We did a similar activity in one of our previous regular lessons before and tied that lesson in with energy changes.
Boys love challenges and they wanted to compete to see whose “fighter jet” was the best.
As time was running out, we had to stop the fun and took out the target board. Immediately, they were impressed and they shifted their attention, even posing as professional dart shooters.
We actually wanted to stop there but somehow one of them discovered there was another board behind! And there was no stopping them. IZ and X even took the stage to explain how the points were accumulated. Impressive! Look how professional!
Last round of dart throwing before we wrapped the lesson.
The lesson was really packed to the brim and overspilled with all the experiments. 2 were unplanned, but we welcome such requests, as this shows they enjoy learning and were confident to ask even though the experiments were not part of the planned lessons. To be honest, the boys were really reluctant to write but we maintain our stand that for any hands on learnt, there must be some form of writing to capture their observations, thoughts which help them link what they see and do.
