Minutes Afloat
A food manufacturer needs a ship to deliver their
products overseas. To save money on fuel, the
manufacturer is looking for the ship design that will
safely transport the most crates of food per trip. To
be considered safe, your ship must float for three
minutes while loaded with the crates of food.
Your job is to design and construct a ship
that can safely carry the most food.

TYPES OF ENGINEERS
Copyright © 2014 Discovery Education. All rights reserved. Discovery Education Inc. is a subsidiary of Discovery Communications, LLC.
TAKING A CLOSER LOOK AT THE ROLE OF
AN INDUSTRIAL ENGINEER
Industrial engineers find ways to eliminate wastefulness in
production processes. They devise efficient ways to use workers,
machines, materials, information, and energy to make a product
or provide a service.
Depending on their tasks, industrial engineers work both in offices
and in the settings they are trying to improve. For example, when
observing problems, they may watch workers assembling parts in a
factory or staff carrying out their tasks in a hospital. When solving
problems, they may be in an office at a computer looking at data
that they or others have collected.

INDUSTRIAL ENGINEER: CASE OF THE
CHOBANI CUP
You will now read a case study that
shows how engineers in the real world
develop innovations to solve everyday problems.
Work with your partner to read the case study. When you
are finished reading, summarize what you learned about
how the engineering design process was used to develop
the Chobani yogurt cup.

HEAT TRANSFER
Heat is a type of energy. It is measured by
temperature. All substances contain heat, even a
cold treat. If there is a difference in temperature in a system, heat
flows from the substance with the higher temperature to the
substance with the lower temperature. Insulation is used to slow
unwanted temperature changes. It can be used protect against
heat or to prevent heat loss.

THE PROBLEM
Each day, Maya packs a cold cup of her favorite
yogurt to eat with her school lunch. By lunchtime,
her yogurt is no longer cold. Maya wants a snack
pack that will keep her yogurt as cold as possible. If
she can keep it cold, she knows it will be safe to eat
and taste great.
