I am ready to learn.

A solid is matter that has a definite size and shape. Solids can only change shape if
they are broken or cut.
The volume of a solid stays the same no matter how you move or turn it.

The particles in a solid are packed together tightly.
They do not move, and they keep their shape.

While particles in solids do not move from their spots, they still have some energy that
makes them vibrate.
When solids get warmer, they vibrate more. Some solids expand when they vibrate.

Solids

Liquids
A liquid is matter that has a definite size but no definite shape.
Liquids change shape each time they move.

They take the shape of their container but have no fixed volume.
Water, juice, milk, and oil are examples of liquids.

The particles in a liquid are farther away from each
other than the particles in a solid.

This means there is more space between the particles in a
liquid.

The extra space allows the particles to slide around and take
different shapes.

Gases
A gas is matter that has no definite size or shape.

Gases do not have a fixed volume, so they will spread out to fill any
space they are in.
Unlike solids and liquids, most gases cannot be seen.

Unlike the particles in solids and liquids, gas particles are very
far apart and move freely.

Gas particles are very small. They are much tinier than even the
smallest things you can see.
They are constantly moving because of the space between
each particle.

Tomorrow we will complete a graded science assignment. Here is what you will need.
If you are unable to have these materials, you are welcome to follow along as I perform the activities instead.
