An object will rise up in a fluid if
Gravity and buoyant force equal
Density of object and fluid is equal
the buoyant force is stronger than gravity
if the density of the object is greater than the fluid
An object will sink in a fluid if
gravity is stronger than buoyant force
buoyant force is stronger than gravity
a fluid can be a gas or a liquid
if the object is solid
What is buoyant force?
A downward pushing force that a fluid pushes on an object
A force that causes an object to sink
A upward pushing force that a fluid pushes on an object
The same as gravity
When an object is immersed in a fluid, it pushes the fluid out of the way and takes its place. This is ...
Gravity
Sinking
Fish
Displacement
An example of neutral buoyancy would be
a fish swimming in the ocean
A rowboat
a rock a the bottom of the lake
A scuba diver sitting in a boat
Design and build a boat out of straws and plastic wrap that can hold 25 pennies for at least ten seconds before sinking. Your materials are straws, plastic wrap, tape and pennies. You have 20 minutes to build before we test.

Problem Statement
A newly constructed bridge was inspected to evaluate the load capacity of the bridge. During the inspection, fatigue cracks and stress fractures were discovered on the deck and supports. After reviewing the original plans, it was discovered the bridge was not built to original specifications (requirements). What did the engineers most likely ignore when designing the bridge?
Planning and developing
Criteria and constraints
Testing the bridge
Safety procedures
Considering the given criteria and constraints, competing factors that will jeopardize the product efficiency will require a:
budget.
specification.
spin-off.
trade-off.
A speedboat is not permitted to go faster than 100 knots in a lake. Therefore, the company decides to redesign the throttle so it cannot exceed 95 knots. This is an example of:
constraint.
criteria.
trade-off.
design challenge.
