I came across this following sentence here but I could not understand what she means by makeshift science project.
Wilmot, now 19, said that in April 2013 she brought a science project to school in Bartow, Florida -- a makeshift volcano that she was very excited to show her teacher.
Volcano is what she did for the science project.
Does she imply her project was not well prepared so it did not look like a real volcano already or is this a standard usage for different meaning than being temporary?
