Science Class
Science ClassThursday, October 1st Technology todayHello All, I
am out today because I am sick. Please be on your best behavior
today.You will complete todays 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 below and answer the
following questions in your interactive notebook:Login info for
Discovery Ed: (username cms id # _ cms) (password cms id#)Record
the following 4 definitions:1 Soluble: 2 Insoluble: 3 Solubility:
4. Saturated solution: What three factor affect the rate of
dissolving?

Study Jams VideoYou will be watching a video on properties of
matterDirections are on the next 2 slides
Video
link:http://studyjams.scholastic.com/studyjams/jams/science/matter/properties-of-matter.htm
Please know.You will be watching and listening to the video 2
times to answer these questions
Study Jams Properties of MatterCopy 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 1. What is density? Density is an
objects mass divided by its volume2. List 3 properties of matter?
mass, volume, density3. Can the mass of an object change? No4. 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) 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 LabThink back.We have learned a new vocabulary word:
DensityWho 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 / mLMass is
measured in?GRAMSVolume is measured in?LITERS
Write this down : Density NotesIf density of a substance >
the density of water = it will sinkIf 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 1.0g/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
notebook1. Rubbing alcohol2. Dish soap3. Pancake syrup4. Milk5.
Vegetable oil6. Water2 minutes
Density lab. #2Next draw this table in your notebook (2
minutes)Think about layering these liquids together the same
containerPredict which liquid would be at each number ayerFor
example if you think the water will end up on the bottom, list
water in #6 3 minutes GO!
Liquid Name1.2.3.4.5.6.Density lab. #21st Watch the
demonstration2nd - Draw another table3rd Record each liquid layer
correctly!

Oil and Water Question?Oils density = 0.926 grams/ mLWaters
density = 1.0 g/ mL
We mix oil and water togetherWhich will be on top?Why?The oil is
less dense that water so it will float on top
