A student studies three different types of bread to see if the type will affect how much time it will take to grow mold. He begins measuring the time it takes the bread to grow mold after 1 week. Which of the following is a DEPENDENT variable

Time it takes to grow mold

Type of bread

Type of mold

How long it sits out

Answer: Time it takes to grow mold

Explanation:

Independent variable is the one which can be altered manually by the experimenter and the effect of the manipulation can be observed on the dependent variable. The dependent variable is the result of the experiment. The three different breads used in the case of study is the independent variable. The time required to grow the mold in this experiment is the dependent variable which is the outcome of this experiment. Different breads can offer different kind of substratum, nutrition, and other conditions for the growth of the mold.

Answer and Explantion

Collect data-This should be the first step in coming up with a design of an instrument to measure a certain property. The data should comprise of the air temperatures, the wind speed values and recorded peak times for the ocean currents.

Build a prototype-This is sample equipment built from the data obtained to be used as a test instrument in predicting the catastrophic weather .The prototype is a mini design of the actual design.

Evaluate the result of their system-The results obtained from the prototype can be used for evaluation to determine the working of the designed devise. The results produced should show a connection that can be used to predict the weather according the values of temperature, wind speed and ocean current values.

Modify their design-After analyzing the results according to the parameters set for the design, the prototype can be improved to obtain a final design which will indeed produce the required results.
