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

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.

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

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

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

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

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

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

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 121-110 11 = X 100 = X 100 110 110 10% error = 0.10 X 100 =

Percent Deviation Example

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

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

More Basic Science Vocab. _______________-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 Water cycle, Rock cycle,Sunspot cycle, Seasons, Motions of planets, sun, stars, and moon Equilibrium Dynamic Equilibrium affects humans in some way.
