density
When you pour oil into a glass of water, the oil floats on top of the water. Which liquid has a higher density?
The water is denser than the oil, so it sinks to the bottom, and the oil floats on top.
if you went to the Moon, would your weight change?
Yes, it would decrease because the Moon's gravity is weaker than Earth's
Which takes up more volume: a large beach ball or a small marble
beach ball
definition of density
A measure of how much "stuff" is packed into a certain amount of space. It's how heavy something is for its size.

ferret
You have a small chip of wood and a large log made of the same type of wood. Which piece is more dense?
They have the same density because density is a property of the material itself, regardless of how much you have
If you went to the Moon, would your mass change?
No, it stays the same
A large bag of cotton balls and a small metal ball have the exact same mass on a balance scale. Which one takes up more space (volume)?
The bag of cotton balls takes up more volume because the cotton fibers and air are less tightly packed than the metal is.
definition of mass
The amount of matter, or "stuff," in an object. It is measured in grams
what was coco and Kate's science light project mainly about
poppi
You drop a ball into a tank of water. It floats. What does this tell you about the ball's density compared to the water's density?
The ball is less dense than the water, so it floats.
You have two boxes that are the exact same size (same volume). One is filled with rocks, and the other is filled with feathers. Which box has more mass? Why?
The box with rocks has more mass because rocks have more matter packed into the same amount of space than feathers do.
Which takes up more space: a ton of bricks or a ton of feathers?
Conceptual answer: The ton of feathers takes up much more space (volume), even though both have the same mass.
definition of volume
the amount of space something takes of
what is coco's favorite ice cream flavor
mint chocolate chip
would something less than 1 gram sink or float?
float
What tool is used to measure mass?
a triple beam balance
would a shoebox or a water bottle fit more books in it? why?
a box because it has more volume to fit it in. a water bottle will simply not fit it in
definition of compact
Packed tightly together. Something with high density is more compact
how many siblings does Kate have
1
how do you find density
divide an object's mass by its volume
What are the common units used to measure mass?
Grams and kilograms
how do you find/measure the volume of water
a graduated cylinder
definition of matter
Anything that has mass and takes up space.
what is coco's favorite fruit
mango
