Observations
Using the senses to gather data from the environment
Tools
May extend the senses
Qualitative Observation
Properties of an item that are not easily measured
Qualitative and Quantitative
Two types of observations
Quantitative
Type of observation where a property can be measured using a tool that extends the senses
Length
Distance between two points
Width
Distance between two points
Height
Distance between two points
volume
how much space an object takes up
Regular Solids
Cubes, Rectangular Prisms, Cylinders, Spheres are examples of what kind of geometric shapes
Formula
The Volume of a Regular Solid can be calculated using a
Rectangular Solids
The Formula V = L x W x H gives the Volume of
cylinders
The Formula V = (Pi) x R2 x H gives the Volume of
water displacement
the volume of an irregular solid is determined using
Mass
How much matter an object contains
Mass is Determined Using
A Balance
Measured using a Stopwatch
Time
temperature
measured with a thermometer
Celsius scale
for most measurements, temperatures are measured on the
Fahrenheit scale
for weather variables, temperatures are recorded on the
density
describes how much mass is found in an amount of space
density
constant for substances at given temperatures
T/F: Density can never change
FALSE
heated
in general, density decreases as a substance is
cooled
in general, density increases as a substance is
T/F: Density is effected by pressure
TRUE
increases
if the same amount of mass is compressed (squished) into a smaller space, the density
decrease
if the pressure of an object, like a gas, decreases, its volume will expand while its mass stays the same, causing the density to
cooled
*EXCEPTION* = water- density decreases as it is
D = M/V is the formula for
density
D = M/V this formula represents
Density = Mass ÷ Volume
you can use the density equation to determine two other things
Mass or Volume
T/F: If you are looking for either mass or volume, put density over 1 and cross multiply and divide
TRUE
