1. What worked well with my model and why?

What worked well with my model was my original plan to make a snake-tank worked and the 3D model looked good. It took 2 hot glue guns and a bunch of cardboard but in the end it car out as I had hoped

2. What did not work well or was difficult with your model and why?

Definitely the hardest part of this project was the actual electric circuit. It took me 4 classes to work out what the resitors did, which wires were negative and positive and how to make the lights work. I had originally planned to make a parallel circuit with a seperate switch for each light but it didn’t work and so I made a series circuit.

3. Discuss what changes were made or should be made to your model from the original design and why they are necessary?

The only changes I made to my project were 1) I didn’t put a door over where the battery is kept and 2) the obvious one, I made a series circuit instead of a parallel circuit

This is the circuit diagram drawing of my finished electric circuit model.

I made a 3 light and switch series circuit

I FINISHED

In the end I was really impressed with how my model and circuit turned out. I was disappointed that I couldn’t work out how to make a working parallel circuit but I was surprised I was even able to create a working light. The model itself looks alright and if I had more time I would go back and paint it

Today I brought a new hot glue gun so I was able to insert the two tank panels and I attached the first light into the tank, but I couldn’t work out how to get another light to work on the same circuit so I am now considering making three separate series circuits.

I began to hot glue all my cardboard pieces together, I put all the walls up and then I painted the insides of the snake areas before I accidentally broke my hot glue gun. Now I have to buy a new one! But i then painted the inside of the snake areas green.
