SCIENCE CLASS Tuesday, October 7 th (A day) Wednesday, October
8 th (B day)
Slide 2
WARM UP Turn in your notebook where you glued your properties
of matter foldable and write this warm up down: Water freezes at 0
C / 32 F Water boils at 100 C / 212 F What state of matter (solid,
liquid, gas) is water at the following temperatures? 214 F
________2 C ___________ 105 C _________-2 F __________
Slide 3
LETS CHECK OUR UNDERSTANDING Water freezes at 0 C or 32 F Water
boils at 100 C or 212 F What state of matter (solid, liquid, gas)
is water at the following temperatures: 214 F _gas_2 C _liquid_ 105
C _gas_2 F _solid_
Slide 4
STUDY JAMS PROPERTIES OF MATTER Copy these questions down in
your notebook: 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? You will be listening to the
video 2 times to answer these questions

Slide 6
STUDY JAMS PROPERTIES OF MATTER 1. 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) 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.
Slide 7
DENSITY LAB Think back to our last class. We learned a new
vocabulary word: Density Density measures how heavy something is
for its size Formula: Density = Mass / volume
Slide 8
DENSITY NOTES Different substances have different
densities
Slide 9
WRITE THIS DOWN ! Density of water = 1.0 gram / mL Mass is
measures in? GRAMS Volume is measure in? LITERS
Slide 10
DENSITY LAB! You will soon be investigating different forms of
matter to better understand density in a group You will receive 1
handout We will go over this handout together before you start the
lab
Slide 11
LAB GROUPS You will count off from 1 5 You will work in the
group number that matches the number you just counted out loud in
our class You have 1 minute to move to your group Go Now!
Slide 12
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
Slide 13
DENSITY LAB. HANDOUT #1 You will test 5 items in your group 1
st -make a prediction 2 nd - drop the item in water 3 rd record
observations 4 th state if it sinks or floats and why 5 th glue in
notebook
Slide 14
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
Slide 15
DENSITY LAB. #2 You will watch a video for the 2 nd part of our
lab First - write down these common liquids 1. Rubbing alcohol 2.
Dish soap 3. Pancake syrup 4. Milk 5. Vegetable oil 6. Water 2
minutes
Slide 16
DENSITY LAB. #2 Next draw this table in your (2 minutes) Think
about layering these liquids together the same container In your
group, predict which liquid would settle in each layer 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.
Slide 17
DENSITY LAB. #2 1 st Watch the demonstration 2 nd - Draw
another table 3 rd Record each liquid layer!

Slide 19
OIL AND WATER QUESTION? Oils density = 0.926 grams/ mL Waters
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
Slide 20
DISCOVERY ED. VIDEOS Density Measuring Volume and Density
Slide 21
HOMEWORK You will receive a handwork assignment now We will go
over the assignment together Does anyone have any questions?
Homework due date: (A day) (B day)
