Remember this!

Matter is anything that has mass and volume.

Let's make sure you really understand mass and volume! They can be tricky concepts.

Select the toy robot to continue.

Mass is a measure of how much matter is in an object or substance.

Thermometer

Stopwatch

Graduated Cylinder

Balance

Select the tool we could use to determine the mass of this toy robot.

Yes! A balance is used to measure mass by comparing an object's mass to known masses. Select the robot to place it on the balance.

Now let's balance the robot. Select the 100 gram mass to add it to the right side of the balance.

The robot is still not balanced. Select a 10 gram mass to add it to the right side of the balance.

The robot is almost balanced! Select one more 10 gram mass to add it to the right side of the balance.

The robot is balanced! The level balance shows the known masses on the right equal the robot's mass.

Select the balance to continue.

Add up the values of the known masses on the right side to determine the mass of the robot on the left.

You got it! The masses on the right total 120 grams, meaning the toy robot's mass is also 120 grams since the balance is level.

Continue

Another tool often used to determine the mass of an object is a scale. A scale measures the force of gravity using springs or electronic sensors and converts it to a mass reading. Select the toy robot to place it on the scale.

You got it! This scale shows that this robot has a mass of 120 grams.

This means that this robot contains 120 grams of matter. Anywhere in the universe, the (fill-in-the blank) of this robot is 120 grams!

But on the moon, the scale reads only about 20 grams!

Eek! The scale shows a MUCH lower measurement!

Technically speaking, a scale doesn't measure mass directly. What does a scale directly measure?

A balance measures mass by comparing an object to known masses, working the same regardless of gravity. A scale measures weight, which depends on gravity, meaning it gives different readings on Earth and the Moon.

This scale does NOT show my correct mass.

The balance shows my correct mass.

This scale is calibrated for Earth's gravitational pull.

Which tool is better for measuring mass when gravity varies, like on Earth and the Moon?

Scale

Balance

That's right! A balance provides the correct mass value regardless of gravity because it compares an object’s mass to known masses rather than relying on gravitational force.

Select the balance.

The balance shows the same mass both on the moon and Earth!

While a balance is the most direct way to measure mass and is accurate in all gravities, a scale calibrated for Earth's gravity provides a quick and convenient way to determine mass here on Earth.

Back on Earth, the reading on this scale is correct!

Select the scale to continue.

This scale is calibrated for Earth's gravitational pull.

I have the same mass as on Earth. But, I weigh less on the moon.

Weight on Moon

Fill in the blank is the amount of matter in an object. Fill in the blank is the force of gravity acting on an object.

We have established that all matter has mass,which can be measured on Earth using a balance or determined with a calibrated scale.

Along with having mass, what else must be true for something to be considered matter?

It must be a robot.

It must be blue.

It must take up space.

Yes! Matter has mass and it takes up space!

Which term refers to the amount of space that a substance or object occupies?

volume

density

weight

temperature

mass

Yes! Volume is a measure of how much space an object occupies.

Select a tool that can be used to measure volume.

Graduated Cylinder

Thermometer

Stopwatch

Correct! A graduated cylinder measures volume.

What is the volume of water currently in the graduated cylinder?

305 ml

300 ml

Measure the volume from the bottom of the curve (the meniscus).

30 ml

1000 ml Graduated Cylinder

Correct! The volume of the water in the graduated cylinder is 300 ml.

What is the combined volume of water AND the toy robot?

400 ml

505 ml

I should have seen that coming!

Toy Robot Mass: 120 grams Volume: 100 cm3

is fun, takes up space

Yes! The toy robot is matter because it has mass and takes up space.

Air in this Balloon

Is air matter?

YES

NO

Mass: 1.225 grams Volume: 1 Liter

Yes! Air is matter. It has mass and takes up space.

The Sun

Is the sun matter?

YES

NO

Mass: 1.9891 × 1030 kilograms3 Volume: about 1,409,272,569,059,860,000 km

The sun has a mass of about 333,000 Earths and a volume of about 1 million Earths!

The toy robot, air, the sun, and anything else that has mass and takes up space is considered matter.

Choose the only option below that IS matter.

Sound

Heat

Energy

Gravity

Time

Feelings

Rainbows

Legos

Light

Yes, Legos are matter. They have mass and take up space. Great work learning about what is considered matter!
