3. There are more than 100 basic kinds of matter, called elements. Elements cannot be broken down into smaller pieces. Examples of elements include gold, silver, oxygen, helium, and iron.

4.  Physical Properties: Physical properties are things that can be observed, described, or measured with tools such as rulers, thermometers, microscopes, scales, and balances. Mass Volume Weight Density Buoyancy Solubility Chemical Properties: Chemical properties explain how matter changes into something new. Rusting Burning Shape Size Texture Color Flexibility Odor Hardness

6.  Matter is anything that takes up space and has mass.  Volume is the amount of space an object takes up  Mass is the amount of matter in something  Elements are the basic building blocks of matter.  All objects made of matter have its own set of characteristics, or properties  Physical Properties: can be observed, described, or measured with tools such as rulers, thermometers, microscopes, scales and balances. For example:  Chemical Properties: How matter changes into other materials, or a new substance --flammability --reactivity with other chemicals –Color –Texture –Size –Shape –Flexibility –Odor –Hardness –Temperature –Mass –Volume –Weight –Density –Buoyancy –Solubility
