Marble sorter

In this activity the students of principles of engineering were assigned a task to sort marbles into three different groups. Metal, wood and clear.

Achievements:

1) Organize it!

2) I've Made a Few Special Modifications...

* Added a fan to push wooden marbles

* Constructed a new hopper

* Disassembled sorter and rebuilt it with many support improvements

3) Reflection

+ : Creative solutions, results fulfill problem statement

- : Teamwork, only a couple of our members were constantly working (together)

? : Next time we need to improve our teamwork, and procrastinate less (and work on focus)

! : Why not have the entire class as one group and make them sort ten different kinds of marbles?

4) Process 15 marbles in less than 30 seconds. (6 to 10 seconds)

5) Marble Delivery

6) Drop marbles from 2 feet above machine

7) Used at least one motor

Here is our marble sorter.

This would catch the marbles and every one thought this would accomplish six feet but we were only able to do two feet.

 

Here is our complete marble sorter we got the three kinds if marble sorted. One group was 5 metal. Second group was 5 wood. The last set of marbles were clear marbles. We did the two feet challenge. 

This was an awesome experience and I have always loved to these type of projects in engineering.
