Hay Horse!Featured science projectScience project video


The materials required for this science fair project:
- 10 horses
- 70kg of alfalfa hay
- 70kg of oat hay
- 70kg of clover hay
- 1 blood glucose tester
- 1 bottle alcohol
- 1 electric shaver
- 30 syringes
- A horse trainer


1. For this science fair project, the independent variable is the type of hay used to feed the horses – alfalfa , oat  and clover hay. The dependent variable is the glucose level in the blood of the horse after feeding. This is determined by using the blood glucose meter to test the glucose level in the horse’s blood. The constants (control variables) are the breed of the horse, the length of time between feeds and the time and method of taking blood samples as well as the amount of hay fed to the horses.

2. 10 horses are selected to participate in this science project experiment. The nature of the science project is explained to the horse owners and permission is obtained before proceeding. A horse handler’s participation will be required.

3. On the first day, each of the horses is fed with 7kg of alfalfa hay. One hour after the horses have finished consuming all of the hay,  Blood samples are obtained from the horses with the syringe or other device that is provided with the blood glucose meter. The blood glucose meter is used to check the glucose level in the horse’s blood. All measurements are recorded in the table given below.

4.  Procedure 3 is repeated on the second day using oat hay and on the third day using clover hay. The measurements are all recorded in the table given below.
