PROBLEM | WILL THE COLOR OF LIGHT AFFECT THE MASS OF FOOD CHICKENS EAT |
HYPOTHESIS | IF THE COLOR OF LIGHT CHANGES, THEN THE MASS OF FOOD CHICKENS EAT CHANGES. |
RESEARCH | INTERVIEW WITH FARMER BROWN ABOUT CHICKENS |
PROCEDURE | 1. OBTAINED TWO CHICKEN HOUSES THAT WERE THE SAME SIZE. 2. PUT 15 HENS IN EACH HOUSE. 3. PUT A BLUE LIGHT BULB IN ONE HOUSE AND A WHITE BULB IN THE OTHER HOUSE... |
RESULTS | THE CHICKENS WITH THE WHITE BULB AVERAGED EATING 40.23 KG OF FOOD PER DAY AND THE CHICKENS WITH THE BLUE BULB AVERAGED 37.89 KG OF FOOD PER DAY. |
CONCLUSION | THE DATA COLLECTED INDICATED THE HYPOTHESIS SHOULD BE SUPPORTED. THERE WAS A MEASURABLE DIFFERENCE BETWEEN THE MASS OF FOOD EATEN WITH THE WHITE BULB COMPARED TO THE BLUE BULB. |
