Question

developing solutions
you use many engineered objects every day. each of them was designed and built to help with a need. cell - phone cases and roller coasters are very different. designing
however, they are both developed using engineering processes.
useful tools, devices, objects, and systems require careful design planning, testing, and
manufacturing. the engineering design process has many steps. although there is not
a fixed order of steps, the design process for a cell - phone case and a roller coaster are
very similar.
every solution begins with a design problem
engineers solve problems. in order to design a solution, engineers must start with a
clearly stated problem. in engineering, the word “problem” does not mean something
that is wrong. instead, an engineering problem is a statement that defines what solution
is needed. the design problem must be stated in a way that describes what the solution
needs to do and how it needs to do it. the problem does not have to be complicated for
an engineered solution to work. the chimpanzees below are not engineers, but they
do have something in common with engineers. they were faced with a problem they
needed to solve.

this chimp uses a stick
to collect stinging ants
from an ant colony
so she can eat large
numbers of them
quickly.

1. language smarts | discuss together with a partner, look at the photo of

the chimpanzee eating ants from a stick. chimps, unlike humans, are limited to
using nearby natural materials to make a tool to gather the stinging ants. in your
own words, state the design problem faced by the chimp.

Explanation:

The chimp needs a tool to collect stinging ants quickly, using only nearby natural materials.

Answer:

How to use nearby natural materials to make a tool for gathering stinging ants efficiently.
