You are managing a large feedlot of cattle. A pharmaceutical company wants you to try a new antibiotic to treat shipping fever in newly arrived cattle. You are currently not using any antibiotic to treat shipping fever in your cattle. The company claims that it is more effective and will save you money using this antibiotic. You will use the same feed, water and conditions of the cattle. You will measure the temperature of the cattle’s fevers to see whether or not the new antibiotic works on treating shipping fever. Identify the following parts of an experiment from the example above:
Independent variable: new antibiotic
Dependent variable:
Constants (controlled variables):
Control group:
Experimental group:

The parts of the experiments that would be used to check temperature to know if this antibiotic works are:

The independent variable is the new antibiotic that is going to be used to treat this fever in the cattle.

The dependent variable is the temperature of the cattle. The temperature of the cattle depends on the effectiveness of the antibiotic

The controlled variable is the quantity of antibiotic that the cattle is to receive.

The control group are those cattle that I own that will not be receiving this drug.

The experimental group are the group of cattle that are going to take the antibiotics.
