Classes 4L and 4/3N take their ‘gearing’ to a new level.

Dear Bloggers,

Many of the models the children make use a gear turning a crown gear to change the direction of the motion 90 degrees. Students were challenged to use this gearing combination in their own designs and write a program to showcase what it can do. Level 1 (advanced) created their own design and geared up or down depending on the function. Level 2 used a stimulus diagram to base their design on but they made a series of modifications. Level 3 (basic) made the model in the stimulus diagram and small changes where possible. The children who made successful level 3 models presented them to the class.

Below are some of the high level models.

Helicopter houses

Cart with turning sign

Cart with a horse and rotating sign

Rotating DJ stand

challenge 1-24

This is the program that the boys wrote for the DJ stand….it is amazing. Let me interpret for you… Nothing happened until the motion sensor detected motion…and then the count down began. Once the display reached 0 an explosion graphic displayed in the window and there was an exploding sound. The DJ stands then rotated one way at a certain power level for a set amount of time and then changed direction and speed. There was also a reset program for the display. WOW boys well done!!!!!!!
