Matter is everything around you! What is Matter?

Matter: a substance that occupies space and has a mass, all physical objects are made of matter, the smallest unit of matter is an atom

Examples of Matter Anything that has mass & volume Pencil, book, car, etc. That includes you  Anything that has mass & volume

All matter has…… Mass & Volume

VOLUME Definition Units of measure Instruments Volume of regular solids, irregular solids and liquids

The space that matter occupies Can measure the volume of a gas, liquid and solid Units of measure = mm³, cm³, m³, ml, L, etc Definition

The following instruments can be used to measure volume (V) Ruler Tape measure Graduated cylinder (most common) Overflow can (less precise) Instruments

How do we measure the volume of LIQUIDS? Use a graduated cylinder We need to measure how much water was displaced *Make sure you look at the bottom of the meniscus Meniscus

Volume Measurement Methods Matter Unit of measure Instrument Method Regular solid mm³, cm³, m³ Ruler or tape measure V=length x width x height Irregular solid mL or L Overflow can and/or graduated cylinder Measure V of water that comes out of overflow can Measure water displaced when placed in graduated cylinder Liquid Graduated cylinder Pour liquid into graduated cylinder Volume Measurement Methods

MASS

Mass: an indication of the amount of matter in a substance, calculated in kilograms(kg), grams(g) or milligrams(mg) Definitions

Definitions- continued Balance: an instrument that measures the mass of an object in grams, also known as a scale Weight: the vertical force exerted by a mass due to gravity measured in Newtons (N) measure of how heavy an object is measured in pounds (lb) Definitions- continued

What is mass and how is it measured? Mass is the amount of matter that something is made of. Example: Elephant = A LOT of matter = LARGE MASS Paperclip = very little matter = SMALL MASS We measure mass with a triple beam balance. Add the value of the riders to find the mass in grams (g) *Make sure the balance is calibrated to 0 before you begin!
