Lab Equipment

Microscope: makes an enlarged image of a very small object.

Graduated Cylinder: measures the volume of liquids and solids

Safety Goggles: protects eyes when using heat and chemicals

Beaker: holds and measures liquids.

Dropper: measures out drops of a liquid

Metric ruler: measures length

Balance: measures mass

Thermometer: used to measure temperature

Anemometer Measures wind speed

Barometer Measures air pressure

Rain gauge Measures amount of precipitation/rain

The Metric System: aka SI (system international) most commonly used system most other countries use it all sciences use it

We will use the following units of measure: Mass = gram (g) Volume = liter (L) for liquids or cm3, cubic centimeter (cm3) for solids Temperature = degrees Celsius Time = second (s) Length = meter (m) Density = g/cm3; 1mL = 1cm3

Length Length: distance between 2 points metric rulers and meter sticks are used to measure length

Mass: measure of the matter in an object

Density mass per unit volume of a material found by dividing mass by volume

Time Time: interval between 2 events

Temperature measure of how hot or cold something is we will use Celsius Water: Freezing= 0 degrees Celsius, Boiling = 100 degrees Celsius ‘normal’ human body temperature = 37 degrees Celsius

Volume: amount of space occupied by an object if you can measure straight sides with standard length units, you can figure volume by multiplying the outer dimensions.

volume can also be measured in liters. BE AWARE OF THE MENISCUS!! Meniscus: the curvature of the surface of water. Always read water levels at the lowest point (bottom of the meniscus)
