Do birds eat more from 9:00-10:00 am or from 3:00-4:00 pm?
 * Guiding Question**

**Background** Birds have to eat. It does make sense that they will eat more in the morning because they haven’t eaten in suck a long time. On the other hand in past experiments scientists have found that time of day does not influence how much birds eat.

**Hypothesis:** I think that more birds will eat in the morning than the evening because they have not eaten all night and need to eat to be productive doing their waking hours.

**Independent Variable:** Time of day

**Dependent Variable:** The number of birds eating

**Control Variables:** **Materials:**
 * feeder
 * location
 * seed
 * day
 * weather (although I cannot control it I need to keep it in mind)
 * birds feeder (bowl)
 * seed (TBD)
 * notebook
 * binoculars
 * data sheet
 * pencil

**Procedure:**
 * 1) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Put bird seed in a bowl
 * 2) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Weigh the bowl
 * 3) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Set the bowl out at 7 am
 * 4) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Take it down and weigh it
 * 5) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Wait until 3 pm
 * 6) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Refill bowl
 * 7) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Weigh bowl
 * 8) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Place bowl outside and wait an hour
 * 9) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Take the bowl down and weigh it
 * 10) <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0in 0in 10pt;">Repeat these steps for three days

My experiment was not very effective. The weather was inconsistent and no birds came. In the future I will have a bird feeder out for a month or more before I start my experiment so that the bird can find it more consinstently.
 * Discussion:**
 * Trial number || Date || Time of day || Bird feeder weight before experiment (g) || Bird feeder weight after experiment(g) || different in weight(g) || Temperature (degrees C) || Wind || Other observations ||
 * 1 || 11-26 || 9-10 am || 454 || 454 || 0 || 12 || none || raining ||
 * 2 || 11-26 || 3-4 pm || 454 || 445 || 12 || 14 || none || overcast ||
 * 3 || 11-27 || 9-10 am || 454 || 454 || 0 || 15 || none || weather-normal ||
 * 4 || 11-27 || 3-4 pm || 454 || 454 || 0 || 12 || none || weather-normal ||
 * 5 || 11-28 || 9-10 am || 454 || 454 || 0 || -1 || 3 mph ||  ||
 * 6 || 11-28 || 3-4 pm || 454 || 454 || 0 || -2 || 6 mph || snowing ||



trials 1 & 2 were on 11-26. trials 3 & 4 occured on 11-27. trials 5 & 6 occured on 11-28

My experiment was inconclsive. This was because almost no birds new of the feeder that I had placed out just for my experiment. Background research suggests that my prediction was correct and birds eat more in the moring but I cannot confirm this through my experiment.
