What is this project about?

Essential Question

What visible and invisible relationships connect the different pieces of an ecosystem?

How can we use models to make invisible parts of an ecosystem easy to see and understand?

Enduring Understanding

The movement of energy and matter is part of many ecological processes.

Models can be used to show systems and their interactions – such as inputs, processes, and outputs – and energy and matter flows within systems.

Models can be used to describe things that can and cannot be seen, as well as show the relationships between key parts. All models have limitations and focus on only part of a complex system.  

Description

Science museums engage visitors with clear, accessible, and interesting representations of science. For this project, you are hired by a local science museum to create a multimedia installation for their new exhibit, Microworlds. The goal of Microworlds is to help visitors understand the visible and invisible processes that take place in all ecosystems. The Microworlds exhibit includes several simple but completely functioning ecosystems. You build one of these ecosystems as part of your installation. Each installation combines a Microworld with explanations and models of how matter and energy move through ecosystems. Your goal is to create an accurate, engaging installation that will deepen visitors’ understandings of how ecosystems function.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
