Exploring Buoyancy with Aluminum Foil Boats

What are the two main factors that determine whether an object floats or sinks?

• Color and shape

• Mass and volume

• Material and texture

• Temperature and pressure

Why does the foil boat float initially?

• It is lighter than water

• It displaces more water than its weight

• It is made of metal

• It has a special coating

What happens to the water level when you add pennies to the foil boat?

• It fluctuates

• It increases

• It decreases

• It stays the same

How do you measure the displacement of the rubber duck using a measuring cup?

• By weighing the duck

• By counting the number of bubbles

• By measuring the height of the duck

• By comparing the initial and final water levels

Why is it easier to read the difference in water level using milliliters?

• Milliliters are more accurate

• Milliliters are larger units

• Milliliters are used in cooking

• Milliliters are smaller units

What is the purpose of using a jar with a marked line for measuring displacement?

• To ensure the object fits properly

• To prevent water from spilling

• To accurately measure the displaced water

• To make the experiment look professional

How do you measure the displacement of an object that doesn't fit in a measuring cup?

• By using a larger measuring cup

• By using a jar and adding water until it reaches the marked line

• By breaking the object into smaller pieces

• By using a different object

What is the displacement of the saber-toothed tiger compared to the rubber duck?

• More than the rubber duck

• Less than the rubber duck

• No displacement

• Equal to the rubber duck

What determines if an object will float or sink in water?

• Its weight compared to the weight of the displaced water

• Its color

• Its shape

• Its temperature

What should you do if you want to try the displacement experiment at home?

• Avoid using water

• Only use objects that float

• Use any object and measure the displaced water

• Use only rubber ducks
