The weekly MinecraftEDU club has been designing and creating interactive structures. They are using redstone to enable the interactive portion of the buildings. Think of redstone as electricity. Students can connect it to power sources such as torches. Levers, pressure plates and switches are available to toggle the power off and on while repeaters push the electricity further. Lively discussions occur during this time offering advice and assistance among students as to how to accomplish their building goals. You can also power mine carts and create roller coasters and functioning railway systems. Our current building project is also making use of the key and code lock mod. Some students are disguising secret entrances that must be activated by a source to open and then they must discover the code to a locked door. It’s like creating a virtual puzzle in Minecraft.
