Code Club is on a break until the end of February. Meanwhile 4th grade students have been coding during alternative recess opportunities when the lab is available.
I have seen a growing interest in coding in BeetleBlocks now that we have a 3d printer available to print artifacts and I am quite thrilled. Most 4th graders have had an introduction BeetleBlocks when we used it to print their names (I have one more 4th grade class to schedule), but printing names of their friends or teachers still interests them.
Some are just curious to print a single shape – cube, cuboid or sphere. Spheres are the hardest to print – even with a small cuboid base, they don’t print very well. Students seem to love the prints that “blow up” as well as the successes.
I asked the snowman creator to add a cuboid below so the print would be successful, and it was.
Recently I printed a cannon that a student had made in BeetleBlocks for a social studies report on the Middle Ages. I asked him to break the code into 2 parts – the barrel and the base thinking that would help the print be successful. It printed out well enough. We glued it together with a 3d pen.
What surprises the students the most is the size of the print compared to what they see on the screen. Even though we went over the the numbers translate into millimeters. I try not to scale anything but instead make them go back to the code and change it there.
Recently I printed a pair of rings. There have been some other rings coded but this was the first project that reached the export to print stage. The 4th grader had started on Monday and measured her finger (with the mm calipers) to code a tube of that diameter. Then we added a sphere on the top. That was all we had time for on Monday. On Wednesday she came in with a list of code she had written down. She had worked on the project at home and didn’t know how to save it so she wrote down the code and brought it to school. She also measured her friend’s finger to print one customized for her.
It only took a few minutes to print. The size will need some tweaking, but I suspect I will be printing more rings in the future. We’ve shared the project for others to see or use.
In September I wasn’t sure what 4th graders could do with BeetleBlocks and every week they surprise me with their creativity. I hope to report more on their explorations in the coming months.
