1. Basic Science Information Notes
Most of this should be review. Be sure to copy down the highlighted information into your note packet.

2. Basic Science Vocabulary
observation- the interaction of one or more of your with the
_______________-objects that have been invented to extend the senses.
-examples include
_______________-interpretation of one or more observations.
-a way to explain what you are observing.
-example
senses
environment
Sound, smell, taste, touch and sight
instruments
Thermometer, meter stick, satellites, telescopes
inference
Round stone was moved by water.

3. Basic Science Vocabulary
_______________-inference that tries to indicate what will happen in the future.
-example
_______________-group objects or events together based on common properties or characteristics
measurement-a means of describing observations using numbers.
-contains a and a
prediction
Weather forecast
classification
Rock types
number
unit
49°F, 10°C, 3.5m

4. Basic Science Vocabulary
time
_________-is the instant at which something happens or the period during which a change occurs.
length-a measure of the
__________-the amount of matter in an object.
__________-the measure of the pull of gravity on an object.
distance between two points
mass
weight

5. Measurements that need to be calculated
volume-the amount of
volume=
 volume can also be measured by using a graduated cylinder
What is the volume of this rock?
space an object takes up
(length)(width)(height)
5 ml

6. Measurements that need to be calculated
__________-property of matter that combines mass and volume.
-how much stuff is packed into a certain space.
-The density of gases can be greatly effected by and
When we study weather we will see how the density of air masses plays a role in weather.
density
mass
Density=
volume
temperature
pressure

7. Measurements that need to be calculated
__________-the measure of force or weight on a given area
_____ _____-measure of the rate of motion
pressure
speed/ velocity

8. Important Calculations
Percentage error
1.____________________-(percent deviation from an accepted value)
-measures errors caused by faulty instruments, careless observations or human error.
-compare the measurements with an
Accepted value
Difference from accepted value
Percent deviation =
X 100
Accepted value

9. Important Calculations
Percent Error Example
Your doctor has an extremely accurate scale and your weight on it is 110 pounds.
-Your scale at home measures your weight at 121 pounds.
-How inaccurate is your scale?
percentage deviation=
Difference from accepted value
X 100
Accepted value 11 =
X 100 =
X 100
110
110
10% error =
0.10 X 100 =

10. Percent Deviation Example

11. Important Calculations
2._________________-how long it takes a change to occur.
  change-the occurrence of an event.
-alteration in the environment
-all change involves a flow of energy from one point of the environment to another.
-The boundary between the regions with different properties is called an interface
event-occurs when the properties of matter or a system are altered.
Rate of change
Energy is exchanged across the boundary.
- example – weather fronts

12. Important Calculations
Rate of change =
example-If the temperature outside is 20 °C at 2:00 PM and it is 26 °C at 2:30 PM what is the rate of change?
Change in field value
Time
Change in field value
Time
26°C - 20°C
6°C = =
2:30 – 2:00
30 minutes
= 0.2 °C/minute

_______________-events that follow set patterns and repeat themselves. -
_______________-condition of balance between opposite forces.
__________________-a balance of changes within our environment.
 polluted- the environment is considered to be polluted when the concentration of any substance reaches a proportion that
Cyclic changes
