Base potato slice straw 45 angle pipet slowly add liquid l.jpg

Base: potato slice Straw: 45° angle Pipet: slowly add liquid


Class discussion what were the results l.jpg

Class Discussion:What were the results?


Slide5 l.jpg

Isopropyl alcohol

Fresh water

Salt water

Glycerin

Clean upCarefully place potato basein trash container…dropping it will splash the food coloring out of the straws!


Class discussion why did the liquids layer that way l.jpg

Class DiscussionWhy did the liquids layer that way?


This beaker is filled with marbles can i fit anymore into this space l.jpg

This beaker is filled with marbles. Can I fit anymore into this space?


Will this salt fit in the beaker l.jpg

Will this salt fit in the beaker ?


Now there is more stuff in here than before can i add anything more to this space l.jpg

Now there is more stuff in here than before. Can I add anything more to this space?


Slide11 l.jpg

This is the same amount of space as when I started with just the marbles, but now there is a LOT more stuff in here.

Jar is filled with water. It has dissolved some of the sugar at the top of the beaker.


Scientists have a word to describe how much stuff is in a certain amount of space density l.jpg

Scientists have a word to describe how much stuff is in a certain amount of space ~ density

density = stuff

space


These terms don t seem official in math what is space called l.jpg

These terms don’t seem “official.” In math, what is space called?

density = stuff

space


Volume l.jpg

density = stuff =

space volume


What do we call stuff in science l.jpg

What do we callstuffin science?

density = stuff =

space volume


Matter which has mass l.jpg

Matter which has mass

density = stuff = mass

Isopropyl alcohol

Fresh water

Salt water

Glycerin

Salt water is more dense that fresh water, because in the same volume (amount) there are dissolved salts and other substances along with the water molecules. This means there is more mass in the same volume ~ making salt water more dense.
