Do You Know What Matter Is? Matter is any thing that takes up space and has mass. Matter also has properties. A property is a characteristic that you can observe about matter. This includes color, texture, size, shape, and hardness. Mass is the amount of matter in a object. Matter is measured in grams.

Buoyancy Do you know what buoyancy is? Buoyancy is the up ward force of water or other liquids

Solid A solid is matter with a definite size and shape. A solid also takes up a definite amount of space. The particles of a solid are packed tightly together.

Liquid Do you know what a liquid is? A liquid has no definite shape ( takes the shape of container) has a fixed or definite amount. It's particles are more free than a solid an moves very slowly

Gas Do you know what gas is? Gas has no definite shape and no definite size. Gas's particles moves VERY fast and free.

Area Do you know what area is? Area is the number of square units that covers a surface. The formula of area is length x width. The red squares are an example of area.

Perimeter Do you know what a perimeter is? The way you can get a perimeter is add 4 all sides. The blue arrows are an example perimeter.

Volume Volume is how much space an object takes up. To get a volume you multiply lengthxwidthxhieght.

Weight Do you know what weight is? Weight is measure of the pull of gravity on an object and you can measure it in newtons and pounds.

The three R's Did you know that there's something called the three R's. The R's stand for reduce, reuse, recycle.

Density Density is the amount of mass in a given space. If you have a 15 gram cup and a 20 gram cup and each one has 12 grams of paper in it the 15 gram cup has more density.

Elements Elements are the building blocks of matter. They are made up of only one type of matter. Gold, silver, and oxygen are some examples of elements. The periodic table sorts the elements by properties.

Atoms Atoms are the smallest particles of an element. Atoms of one element are all alike. Atoms have a nucleus, protons, neutrons, and electrons. Protons and neutrons are inside the nucleus. Protons have a positive charge and can't leave its atom. Neutrons have no charge. Electrons have a negative charge.they travel in a cloud outside the nucleus.

Mixture A mixture is two or more types of matter combined but are not blended entirely together. Mixtures can be separated by sorting or picking, a filter, or evaporation. Some examples are mixed vegetables, salt water, and grape juice.

Compound A compound forms when two or more matter are combined chemically. Each element loses its properties when combined.

Alloy A mixture of two or more elements one must be metal. Mixing metal with another element can make it stronger.

Physical Change Physical changes begin and end with the same type of matter. Heat energy and loss of heat energy causes matter to change state. The mass of the object stays the same. Matter can change in size/shape, change in texture, change in position, and change in state.

Chemical Change A chemical change has different properties than the matter you started with. You start with one matter and end with another matter. Chemical change involves energy either takes in or gives of energy. Penny + vinegar= copper acetate.
