1. Your neighbor told you that it's important not to fill the feeder too often or to fill the feeder too seldom, so how can you determine how often to fill it? What's mathematically important about how the birdfeeder empties? Are there any important variables? 2. When you go over first thing in the morning, the birdfeeder - which has 4 holes, one pair near the bottom and another pair about halfway up (shown in the picture) — is nearly full. You check back 45 minutes later and it's about half full. When do you expect it to empty again? Perches Feeding Holes 3. You come back 45 minutes later and it's still not nearly empty. Why is that? The birds are still coming by consistently to eat, so they still are hungry. When should you expect the feeder to be nearly empty and ready for you to fill it again? 4. Describe a method for calculating when the birdfeeder should be empty. Use mathematical notation, if you can.
You did so well taking care of your neighbor's birdfeeder that she recommended you for a weekend job watching over one of her colleague's birdfeeders. This bird- feeder has 6 feeding holes, with pairs equally spaced as shown in the picture. 5. The first morning you get there, you notice that the feeder is about 2/3 full. You wait a while and notice that it takes about 30 minutes before the feeder is about 1/3 full. How long will it take before you need to refill the feeder? How long will it take for the feeder to need to be refilled after that? 6. Build a mock birdfeeder like the one above to test your answers from question 5 above. Use a clear, cylindrical container as the birdfeeder and rice as the food. How well did your mathematical model agree with your physical model? How should you track your findings? Are there certain important events? 7. Write a mathematical description of how to determine how quickly the birdfeeder will empty. 8. Can you generalize the description above? Are your answers from questions 4 and 7 similar? How so?
