Week 3

| Figure 1: <if> -<then>-<else> block in Scratch |
The <if> portion requires a question to be asked with a yes or no answer. Based on the answer, the block would do one function or <else> it would do another. We ran a simple activity to show this to the students. I tapped each student on the head and asked "Do you have brown hair ?". If the answer was "yes" the student went to the left and waved their arms, if the answer was "no" the student would go the the right and jump up and down. At the end we had sorted all the students with brown hair into a hand waving frenzy, with non-browns jumping.
The activity for the "SCRATCHERs" this week was to use the <if> -<then>-<else> block in Scratch to perform some simple function. As well, the students need to continue with the next tutorial in Scratch and save each tutorial when completed.
The "GURUs" need to continue with their game, being careful to obey the rules of pong as closely as possible (scoring, realistic ball motion and bounce from bats, ball reset to the center when the point is lost).
The "APPERs" are still having connection issues between the school computers and the tablets using the MIT App inventor, so until resolved we have started them looking at Arduino in Scratch, by controlling an LED, speaker and servo connected to a simple robot. Details of the activity and installation required can be found here (setup by some vacation students I had in 2014).
Keep programming and save your results
