Warm up
1. What is the first thing you should do when instructed to read from a
textbook?
2. After you outline your reading in a textbook, what should you do next?
3. What is the last thing you should do when reading a text that will
help the information stick into your brain?
1.From your reading of 1.1, how would you describe matter?
Chapter 1; Section 1Pages 4-10
Everything on Earth is made of MATTER. All Matter has:
Mass Volume
Is air made up of matter? Why or why not?
Watch the teacher demo.
1.What 2 properties do all the things in these pictures have in common?
2.What is matter?
Mass The constant amount of matter
something is made of
Measured on a ___________________
Measured in ____________________
Does NOT change when location changes
NOT the same as weight
Balance
Grams
If an object has a mass of 1 kg on Earth, what would its mass be on the moon?
Inertia Objects resistance to moving
Objects with _____________ mass are harder to get moving than objects with ___________ mass
Mass is a measure of inertia
Larger
Smaller
Would it be more difficult to kick a soccer ball or a bowling ball into motion?
Why?
Gravity
The force of attraction, “pull” between objects
due to mass
Attraction depends on mass and distance Larger masses have greater gravity Smaller distances have greater gravity
GravityWhich has the largest gravity
and why?
GravityList the
objects on this page in order from least to
greatest gravitational attraction to
Earth. Explain why.
1.How is inertia related to mass?
2.Which of these pictures has the greatest inertia? Why?
Weight measure of the pull/force of gravity on
an object’s mass
• =Mass times the force of gravity (Wt=m*g)
• Gravity (g) on Earth=9.8 N/kg
• Measured in Newtons (N) on a Spring Scale
• Changes with change of location
Weight
• Example:• If an object has a mass of 50kg on
Earth, what is its weight?• Wt = m * g• Wt = (50kg)(9.8N/kg)• Wt = 490 N
Mass and Weight:
• What is the mass of the wooden block Mrs. Lock has?
• How much should that block weigh? (we are on Earth, so gravity is 9.8 N/kg)
What is the difference between Mass and Weight?
Make a Venn Diagram that gives some of the differences and similarities between mass and weight.
Complete the WeightPaper that Mrs. Lock
gave you.Work with your partner.
1.What are some differences between mass and weight?
2.What are some similarities between mass and weight?
Mass of an object =10 kg
1.What is the weight of the object on the moon (G=1.6 N/kg)?
2.What is the weight of the object on Venus (G=8.9 N/kg)?
Volume How much space something takes up
Measured with a ___________ ___________
Surface is curved; called a ____________
Read the _________ of the meniscus
Measured in _________
Graduated cylinder
Meniscus
Bottom
mL
Listen to the sounds of the beakers as Mrs. Lock taps them.
What do you notice about their sounds?
What relationship can you make between volume and the sound the glass makes?
TRUE or FALSE
1. The volume of a gas can be measured with a graduated cylinder.
2. If you know the volume of the sealed container a gas is in, you know the volume of the gas.
TRUE or FALSE
1.How do we find the volume of a regular solid like a block?
2.What is the relationship between 1 cm3 and 1 ml?
Complete the RainbowVolume Activity that
Mrs. Lock gave you.
Work with your partner.
1.What is 1 thing you learned a about matter?
2.What is 1 thing you still would like to know about matter?
