Ideas for Presentation

Idea 1

 My first idea that came to mind for an If/else statement was to have a chain reaction. The model would start with an action which the user will do to stat the chain reaction. My metaphor would be something along the lines of If/else is the start of a process. I would start to explain that if the chain reaction is triggered then it is a process else it is still and not affecting the rest of the program. I would most likely use materials that I have easy access to I think that if was to buy something’s for this project it wouldn’t cost too much. I expect to spend about $20 on this project.

Idea 2

The second idea that I had for an If/else statement was to have a model of a man in a glass or acrylic box and when you put a magnet on the top of the box he will stand up straight but if the magnet is not of the top of the box he will be at the bottom of the box. My metaphor for this idea would be If/else is a man in a box ready to be woken up. I would explain that if the magnet is on the top of the box the man is standing else he is lying or sitting down. The materials I would use would be either glass or acrylic for the box and paper or a fabric for the man and magnets to get the man to stand up. The magnets will be attached to the man so when another magnet is on top of the box the man will stand up. I think that I would spend about 20 on all of these materials most likely I would spend less.

Idea 3

My third idea for the If/else statement was to have a small door which you can not open until you unlock it. I would have the key sitting in front of the door and then the user can pick it up and unlock the door. My metaphor for this idea would be An If/Else statement is a door ready to be unlocked. I would explain that an if statement only starts to work if something specific happens in the project to set it off which is exactly like a locked door (the door is only open if the door is unlocked). The material I would use for this idea would be some wood for the door which I will be able to make, a small locking mechanism which would go in the door and will be able to lock and unlock the door and I would also need to make a key. I think I could make the door out wood and the rest out of some sort of metal or wire. I think that all the materials I will need would cost around $20.
