Teaching weight, mass, volume and density with educational music: a rap song comparing and converting units.
“Weight, Mass, Volume, Density” helps students learn the difference between mass and weight by using examples comparing the two and describing the relationship between them. The song also helps students learn the difference between volume and density by explaining the formula for calculating density of an object, which is the mass per unit volume, or mass divided by volume. The song is also useful for lessons involving conversions between these measurements and learning more about pressure. The teaching materials, including worksheets and online resources, can help scientists, teachers, and homeschool parents create lesson plans in physics, math, geometry, and more using song topics. Students will acquire knowledge and skill at working with measurement units and formulas.
This science song is suitable for teaching weight, mass, volume, and density to advanced elementary school (5th grade and 6th grade), middle school, high school and home school students as well as beginning level college classes.
Let’s discuss the difference between weight and mass
People confuse it everyday in every way and let it pass
Weight is the measurement of force of gravity on a matter
And mass is the quantity of matter on the platter
It’s easy: volume is space I’m taking, getting fatter
density is the ratio of mass to the volume in the place
And this data is all you need to know
So let me break it down really quickly before I go
When you’re holding a bowling ball before you bowl it
You know that there’s a force on your hand, you can’t control it
It’s gravity pulling down on the mass of the ball
And that force is called weight, what we’re mastering y’all
But just wait: wait just a minute, man
The ball doesn’t weigh 3 kilograms
That’s the mass of the ball, just so understand
The weight is the gravitational constant known as G
Multiplied by the mass of the earth
Multiplied by the mass the ball, which is 3
Divided by the radius between the center of the earth
And center of the ball squared
If you’re asking, mass is a unit. It’s a quantity of matter
Weight is a force that occurs when gravity happens to be present
On the earth or the moon, measured with a balance,
The mass is the same, cousin
volume is the space occupied by a body
Abide by the laws of physics just to record it
When you look at it, it’s easy to see
The volume of a cube is the length of any side to the power of three
When you wanna measure the volume of a sphere, dude
You can be a beginner and still figure out
The volume of a cylinder with these steps here:
The height times π times the radius squared
So extensively, we move on to density
A measurement of mass over volume
For example: the density of water is 1 g/cm³
So you understand
It’s all a part of the plan to get the knowledge
From my rhyme to your mind to your hand
Measure the volume of a can in simplicity
With weight, mass, volume, and density
Although this site is quite dense for a young student, the information is excellent and clearly expressed and great as a teacher source. The experiment and activity at the end is an excellent way to give a visual understanding of weight, density, matter and volume. Excellent site for the middle school science buff!
