SCI - Floating & Sinking - Buoyancy

Question 1

What is WEIGHT?

Accepted Answer

The way gravity pulls at an object's mass.

Question 2

Scientific Method - What Step? - Develop a procedure to test the hypothesis

Accepted Answer

Experiment

Question 3

Eureka! How did Archimedes figure out that the crown was part silver, and not pure gold?

Accepted Answer

Silver would make the water rise more (used more for weight)

Question 4

BUOYANT FORCE is...

Accepted Answer

the amount of space an object occupies under water.

Question 5

What does CALIBRATE mean? We had to do this to our spring scale and plastic cylinders.

Accepted Answer

To mark or gauge with a standard scale or measurement.

Question 6

Scientific Method - What Step? - State the Problem

Accepted Answer

Purpose

Question 7

What does it mean to DISPLACE water?

Accepted Answer

An object put in fluid will push it away and take the space., An old man figured out that water overflowed when he got in!

Question 8

A ship doesn't float because it is "light". It floats because it has...

Accepted Answer

equal force pushing up on the ship & down against the water.

Question 9

Scientific Method - What Step? - Record the results of the experiment

Accepted Answer

Analysis

Question 10

Scientific Method - What Step? - Predict the outcome to the problem

Accepted Answer

Hypothesis

Question 11

What is GRAVITY?

Accepted Answer

When objects are attracted to one another based on mass.

Question 12

When I change the shape of a single piece of clay without adding or taking any away I can...

Accepted Answer

alter its buoyant force, which could help it float.

Question 13

What is MASS?

Accepted Answer

The amount of "stuff" an object is made of.

Question 14

Scientific Method - What Step? - Find out about the topic

Accepted Answer

Research

Question 15

Why did some objects float even though they were HEAVIER than others that sank?

Accepted Answer

The heavier object's bottom (hull) has more buoyant force.

Question 16

Scientific Method - What Step? - Compare the hypothesis to the experiment's conclusion

Accepted Answer

Conclusion
