6th & 7th grades in Mrs. Daniel's Science class presented their SPRK Ball projects. 7th graders designed a carrier that would go over the SPRK Ball to transport band-aids and paper towels. They were given a scaled-down version of the maze and had to calculate the distances the carrier would travel and program them into the SPRK Ball software. While they could practice the route in the classroom, they only had one chance of presenting with the actual course on Presentation Day. This is to simulate situations in science, such as how astronauts prepare for sending spacecraft into outer space: they can prepare based on previous information, but they won't know for sure how it will work until it runs. 6th graders created a 2D maze on graph paper, scaled it up to a larger sheet of bulletin board paper and drew it, turned their 2D maze into a 3D maze on Makers Empire, and coded their SPRK Balls to travel the maze. Every move of the SPRK Ball was programmed ahead of time and on presentation day both classes only had the chance to test their codes for accuracy.
