Floating and Sinking Quiz

What characteristic or quality of a substance enables it to be effectively carried or transported by water when it is placed in the water?

• lower density

• lower flexibility

• higher solubility

• higher conductivity

The image shows that a coin wrapped in aluminum foil sinks, and that a coin placed on a boat-shaped piece of foil floats.What factors affect the floating and sinking capability of a substance?

• color and texture

• weight and volume

• thickness and quality

• temperature and density

A student designed a paper boat and noticed that adding more coins caused it to sink. The student then wrapped the boat with a material to help it float longer, as shown below. Which of the following materials is the best choice to make the boat float longer?

• an iron sheet

• a cardboard box

• some plastic film

• a layer of sponge

What does buoyant mean?

• to float

• to push

• to fly

• to sink

A student designed two different shapes of aluminum foil boats and conducted an experiment by adding marbles to determine if the boats would sink or float, as shown.

What can be predicted based on the experiment?

• Both boats will sink after some time.

• Both boats are equally effective at carrying marbles.

• The boat with a flat and large surface area base can float more in water.

• The boat with a round shape and a small surface area base can float more in water.

Which three items can be used to build a boat that can float a dense substance on water?

• as Iron Sheet

• a Plastic Bottle

• a Concrete Brick

• a Wooden Block

• a Styrofoam Cup

What is the key expectation in the design stage of the engineering process?

• to start building the vessel immediately

• developing a clear sketch or blueprint of the vessel

• ignoring the problem definition and building randomly

• presenting the final vessel without a sketch or blueprint

Why is it important in the engineering design process to improve the vessel after testing?

• to restate the defined problem

• to ignore the feedback and test results

• It is not important to improve the vessel after testing.

• to enhance the design of the vessel based on test results

Why is it critical to assess a vessel's performance under diverse conditions?

• to simplify the design process

• Testing under various conditions is not vital.

• to confirm it functions in specific environments only

• to guarantee its effectiveness in expected and unexpected scenarios
