They are commonly known as the roly-poly‚ also pill bug‚ and wood lice. Its scientific name is Armadilidum vulgare. It is actually not an insect‚ it is an isopod ( a type of arthropod).

Problem: Do Pill bugs prefer being in an environment with tight spaces‚ or a more open environment? Hypothesis: If the pill bugs are given a choice of an open environment or one with tight spaces‚ then the pill bugs will respond by going to the environment with tight spaces. Brief Methods We used a Petri dish with 2 circle‚ and an opening connecting the two. We put 10 Pill Bugs in the opening between the two circles‚ and timed them for one minute. This gave them time to choose dish 1 or dish

Food Preferences in the Sow Bug (Porcellio Laevis) Purpose The purpose of this experiment is to determine what kind of food the sow bug prefers; decaying leaves‚ potatoes‚ grapes‚ or sow bug food. Hypothesis If a sow bug is placed in a choice tray‚ and has access to decaying leaves‚ potatoes‚ grapes‚ and sow bug food‚ the sow bug will choose the decaying leaves over its other options. This hypothesis was based on research stating that a sow bug’s main food source is decaying vegetation. This

Value Net Present Value (NPV) is used in capital budgeting to analyze the profitability of an investment or project. NPV is found by subtracting the present value of the after-tax outflows from the present value of the after-tax inflows. Investments with a positive NPV increase shareholder value and those with a negative NPV reduce shareholder value. In order to compute the NPV for Worldwide Paper Company‚ we have to calculate the cash flow in capital budgeting of the project as below. | | 2007
