## States of Matter

William Ferriter's insight:

This video is a nice introduction to the different states of matter.  What makes it interesting is that the host of the video segment asks regular people to describe the differences between the states of matter.  Few of the people interviewed can give him a scientifically accurate description of why matter exists in different states.

If you asked your friends and relatives to describe the differences between the states of matter, do you think they could do any better?

## States of Matter and Phase Change

William Ferriter's insight:

This 10 minute PowerPoint presentation with integrated video clips introduces all of the core concepts that we are required to learn about states of matter and phase changes.  While it is probably the most formal video in this collection, it is also probably the best at presenting all of the information that you will have to know for your test in a simple, direct way.

## 7 Layer Density - Cool Science Experiment

William Ferriter's insight:

One of the activites that we completed in class during our unit on matter involved mixing liquids together and finding out that they formed into layers based on the density of the substances that we were trying to mix.

Can you explain the science behind that experiment?  Why is it that the different substances we were mixing formed into layers?  How does density -- which refers to how tightly packed together molecules of a substance are -- play a role in the layering of the liquids in our experiments?

## Density Practice Problems

William Ferriter's insight:

The formula for density is something that we're required to study in our class.  In this video, you can learn how to apply that formula to figure out the density, mass or volume of a material.

For our class, the first two minutes of the video -- where Tyler introduces how to calculate the density of an object when given its mass and its volume -- is the most important to review.

The remainder of the video -- where Tyler introduces how to calculate the mass of an object when given its density and volume -- is a bit more advanced.  You are free to study it, but it won't be on our test.

## STATES OF MATTER

William Ferriter's insight:

This video is visually interesting because glass artists convert glass from a solid to a liquid and back again.  In scientific terms, that's evidence of a phase change.

Can you explain the science behind a phase change?  What has to be added and/or removed for a phase change to occur?  How are the molecules of a substance affected during a phase change?

## Phase Changes of Water Song by Mr. Edmonds

William Ferriter's insight:

In this video, Mr. Edmonds -- the teacher responsible for recording the density song also included on this Scoop.it page -- describes what is happening when water goes through phase changes.

## Science Rules! Topic: DENSITY

William Ferriter's insight:

In this video, a middle school science class explains the core concepts of density, mass and volume.  Perhaps the most interesting moment of the video comes when they drop a can of regular Coke and a can of Diet Coke into an aquarium full of water.  One of the cans sinks while the other floats.

Can you explain the science behind why that happens?

If both cans have the same volume -- meaning they contain the same number of ML of soda -- why would one push its way through the water in the aquarium while the other can't?

## The Density Song by Mr. Edmonds

William Ferriter's insight:

Mr. Edmonds is a science teacher who writes and records songs about important science concepts.  In this video, he introduces density.

Is it helpful to you to have a song to listen to when studying science concepts?
