Can students go to the Makerspace during their lunch and/or recess? Students can not come in during their lunch but they may not come in during their recess.
Why would the Makerspace be closed? I might have to go to another building, leave the room to eat, go fix something, go potty, work with a teacher, participate in a meeting, and/or work with students. It also may be closed because it is reserved or is already at its student limit.
What if a student just needs help with a Chromebook, or needs to get a Chromebook loaner, or just needs to get something from the Makerspace like cardboard? Send them. No need to email. However, I may not be in the Makerspace. You can check the Makerspace site Home Page to see if it's open.
What about 3D Printing? Kids love 3D printing! Send the student to the Makerspace before noon - if it's open. The design has to be created by the student in Tinkercad. I won't print designs that aren't actually created by the student (i.e. I won't print designs someone else made that they search for and import into Tinkercad). The design should have something to do with what the student is learning. 3D printing is first come first serve. I don't create a queue of students who want to 3D print. Also, I don't 3D print at the end of the day. I need to be at school to ensure that the 3D print is printing successfully.
What about green screen recording? Kids love to be in videos? In order to do a green screen recording students have to have a script prepared. It doesn't have to be printed out. A Google Doc will do just fine. Students also need to be practiced and ready.
