Problem: Normally Yertle the Turtle is fed one pellet at a time with a set of tweezers. When we drop more than one pellet into the tank, he doesn't see it. This causes the food to dissolve and make the tank dirty. The current method of feeding him one pellet at a time by hand is time consuming and means that someone needs to be at the school every day.
Criteria:
- keep the tank clean
- be easy to use
- cheap
- durable
- dispense pellets one at a time
- store up to 7 days of food
- can dispense all sizes of turtle pellets
Constraints:
- not harmful to turtles
- can't get stored food wet
- can be used in any tank
- reusable
We will create a design on paper and then evaluate and optimize the designs. There may be several iterations before we get to the best design.
This week in school, we will work on writing the proposal and next week's math lab will include building a prototype.
