WEEK 3 (06/05/15)

Flowers continue growing at a regular velocity, lentils have started to grow in the fertilized soil part but there is still nothing in the normal soil. Parsley is in the same state than the last day. The water continues condensating and there is still water in the tank.

VARIABLES:

Independent: Those that we voluntarily decided to alter; in this case we would say that we mean the product of the mass by increasing / temperature variation.

Dependents: are those who will be affected depending on how we treat the independent variable, so this will be the product of the time and power by.

Subsidiaries: Those that remains constant so as not to unduly affect the way in which the independent variable affects the dependent. Then we say that in this case will be the way of measuring the temperature in the experiment, the heater power, the time spent and finally the initial temperature.
