The kids and I ended up christening them “marker bots” as we felt that described our own creations a bit better. There’s some truth to that as many of the examples we saw used markers (since they scribble more easily), but as they tinkered, the kids began breaking out of the traditional “sample” bot and into new and uncharted territory.
My six-year-old had the most physical limitations as his dexterity isn’t nearly as well-developed as the two nine-year-olds. He had trouble getting the markers to stay and needed more help with setting up the battery. If I were to do this with lots of young students, I would do what many others have suggested and try soldering small washers onto the ends of the battery wires to make it easier to connect and disconnect in the broccoli band.
My sons’ friend was at our house and participated in our “maker” afternoon. I think he enjoyed himself and really learned to apply some growth mindset to his creation. Initially, he had a tough time deciding how to design his bot, but he eventually modified his design and took away the markers and created a moving robot. Success!
My nine-year-old jumped right in and loved that he could make a bot almost exactly like the same one we saw in the course video (strawberry baskets). After figuring that out, he went on to modify his creation and created a ledge for his bot to hold the marker caps.
All told, we spent a good hour and a half tinkering with our creations. A few days later, we revisited the single battery and motor combination and I tried to make a Lego car move (unsuccessfully) and my six-year-old, inspired by his friend’s creation, decided to make an airplane. Although his plane didn’t move he made multiple modifications and we did all sorts of battery and motor tests. Funny enough, everyone single boy who has come over has glanced at it with a “whoa…cool, dude” sort of look. Needless to say, he is quite happy with it.
This assignment was one of the easiest to attempt and to complete. The entry materials are low — a 3V motor, a single AA battery and whatever craft supplies you have in the house. And, if you need more assistance, check out the Exploratorium’s online guide.
