Unit 1 Scientific Method: Day 12 - Measurement - Mass and Volume

Mass and Volume
What is mass?
What is volume?
How are they similar? How are they different?
How are mass and volume measured?
New Questions
What We Know

Source 1: Lecture

Source 2: Stations

Source 3: Reading (Homework)

One way to organize our learning is an inquiry chart.

1) Answer what you already know about the subject.

2) Sources are what help us know more about the topic. They can be labs, lectures, readings, or videos.

3) As we learn more, we should be asking questions.

Beach Ball Station
1) Which object takes up more space?

2) Which object weighs more?

3) Which object do you think has the most mass?

4) The beach ball is filled with air and the other ball is filled with solid metal. What could this tell you about the mass of air?

“Black Canisters” Station
1) Does Canister A have more mass than Canister B, or do they have equal mass?

2) Does Canister A have more volume than Canister B, or do they have equal volume?

3) Why do you think that Canister A has more mass than Canister B?

4) How is it possible for two objects to have equal volume, but one have more mass than the other?

Graduated Cylinder Station
1) Use what you learned last year to measure the volume in the two graduated cylinders.

Graduated Cylinder A: __________ mL

Graduated Cylinder B: __________ mL

2) Carefully pick up both graduated cylinders. Which one feels like it weighs more?

3) Which graduated cylinder do you think has more mass?

4) Why?

Metric System Rap

Meters, liters, and grams
Now you don’t have to cram for your exam
On the metric system

Verse I
Let me start with ways you can measure a distance, length, or height
Mad tall or super small, one of these will do you right
If you try walking a meter, it’s easy to complete
Because a meter’s just a little bit more than 3 feet
But if you’re walking a kilometer it’s gonna take a while
It’s 1000 meters, that’s over half a mile!
A centimeter’s dinky, the width of your pinky
100 of them go into a meter, you still with me?
There’s another kind of meter smaller than that
It’s not very fat, it’s called a millimeter in fact, and it’s tiny
1000 of them in a meter fit
That’s 10 in a centimeter, and that’s it!

Chorus (x2)

Verse II
Now we’re moving on to the liters, measuring liquids in containers
We’ve only got 2, it won’t take long to explain this
A liter, it’s half a big bottle of soda pop
And a milliliter, it’s just about 20 drops
There’s 1000 milliliters in a liter you know
So if you got both of those you’re good to go
Now we can move on to the grams, measuring weight
Kilograms, milligrams, yeah we’re keeping them straight
It’s pretty simple. A paper clip weighs about a gram
A big textbook is a kilogram, man, but
A milligram, that’s a little harder to slice
Because 10 milligrams is about a grain of rice
1000 milligrams, is a gram
1000 grams in a kilogram
Now we got grams and we also got liters
Put ‘em all together with the meters

Now fill in the Inquiry Chart for “Source 3,” using what we did today in class as a model. Your source is the rap above.
