Mixtures that are solutions and not very easy to separate are:
powdered lemonade, hot chocolate, instant pudding.

A chemical change results in
the formation of a new substance.

When water changes states, water can always go back to liquid,
so this an example of a physical change.
In the morning you noticed the grass was damp, during the day the sun caused the water to evaporate.

Mass
is the amount of matter in an object.

Sugar inside of water dissolves the fastest if
the water is hot and even faster if it is stirred.

A physical change is a change, but
you can get the new substance back to its original state.

Evaporation is the change of water from
liquid to a gas, also known as water vapor.

Solution
is a mixture of two or more kinds of matter evenly spread out.
300
Solutions cannot be separated by a screen or a filter because
the parts are mixed together in a way that they all have the same size.

When water and sugar are mixed together, the best way to separate the two is
to let the water evaporate.

Solid has
a definite volume and definite shape.

Volume
is the amount of space something takes up.

A mixture can be separated easily by
your hands, magnets, or using a strainer, filter, or evaporation

Chemical Change examples:
when an iron nail rusts, cooking, decaying of plants, digestion, and anything burning.

Condensation is the change of the physical state of matter from
gas phase into liquid phase.

To find volume of a small object I could:
put a certain amount of water in a cylinder and then place the object inside of the water and then see how much higher the water level rose inside of the cylinder

Atom
Is the smallest piece of matter that can still be identified at matter.

Mixtures that are easy to separate are:
Salad without dressing, red Fruit Loops from the other colored fruit loops, pens from pencils, quarters from pennies, raisins from the bran.

Examples of physical changes are:
ripping apart a paper, breaking glass, cutting down a tree.
