TECHNOLOGY TODAY
 Hello All, I am out today because I am sick. Please be on your best
behavior today.
 You will complete today’s activities on a chromebook.
 Go through each slide and complete the activities within the ppt.
 Record all information on a separate sheet of paper and we will get this
information into your science notebook tomorrow.
 Thanks!!
TO FINISH OUR DISCUSSION OF
SOLUBILITY:
 To ensure everyone understands solubility, you will click on the video link

STUDY JAMS VIDEO
 You will be watching a video on properties of matter
 Directions are on the next 2 slides
 Video link:

PLEASE KNOW….
You will be watching and
listening to the video 2
times to answer these
questions
STUDY JAMS – PROPERTIES OF
MATTER
 Copy these questions in your notebook
after the Temperature
and Solubility Lab (Leave space in between each question so you
can write the answers)
 1. What is density?
 2. What are 3 properties of matter?
 3. Can the mass of an object change?
 4. How can we determine the volume of round or weird shaped
objects?
 5. Why do beach balls float and golf balls sink?
STUDY JAMS – REVIEW YOUR ANSWERS
What is density? Density is an objects’ mass divided
by its volume
2. List 3 properties of matter? mass, volume, density
3. Can the mass of an object change? No
4. How can we determine the volume of round or
weird shaped objects? You can put it in water and see
how much the water is displaced (or how much the
water level moves up)
 1.
5. Why does a beach ball float and a golf ball sink? Beach
balls are less dense than the water and golf balls are more
dense than water.
DENSITY LAB…
Think back….
We have learned a new vocabulary word:
Density
Who can read the definition of density from their
notes?
Density is….
WRITE IN NOTEBOOK AFTER STUDY
JAMS QUESTIONS
Formula: Density = Mass / volume
Different substances have
different densities
WRITE THIS DOWN !
Density of water = 1.0 gram / mL
Mass is measured in?
GRAMS
Volume is measured in?
LITERS
WRITE THIS DOWN : DENSITY NOTES
If density of a substance > the density of water =
it will sink
If density of a substance < the density of water =
it will float
DO WE UNDERSTAND?
Does everyone understand why some objects
float and some objects sink?
It is all because of density!
Objects float in water = density <1.0 g/mL
Objects sink in water = density> 1.0g/mL
ONLINE DENSITY LAB!
You will soon be investigating
different forms of matter to better
understand density
DENSITY LAB….
You will watch a video for our lab (video link on a
following slide)
First - write down these common liquids in notebook
1. Rubbing alcohol
2. Dish soap
3. Pancake syrup
4. Milk
5. Vegetable oil
6. Water
2 minutes
DENSITY LAB…. #2
Next draw this table in your notebook (2 minutes)
Think about layering these
liquids together the same
container
Predict which liquid would
be at each number
For example if you think the
water will end up on the bottom,
list water in #6
3 minutes – GO!
Liquid Name
1.
2.
3.
4.
5.
6.
ayer
DENSITY LAB…. #2
1st – Watch the demonstration
2nd - Draw another table
3rd – Record each liquid layer correctly!

OIL AND WATER QUESTION?
Oil’s density = 0.926 grams/ mL
Water’s density = 1.0 g/ mL
We mix oil and water together
Which will be on top?
Why?
The oil is less dense that water so it will float on
top
