This class went much better than the previous classes in the sense that more children were able to finish their projects and assignments in time, which gave them a bit of free-play time at the end of the class. As usual, this class allowed them to practice scientific concepts related to mechanics and supplied them with an in-class assignment to make sure they have grasped the material. Concepts such as preservation of energy and inertia were practiced, and the assignment asked them to predict the position of their vehicle after it had been launched. I was very happy with their performance, and even happier to see that their work is improving each week.
