Physics (Science) is EverywhereUnit One

We need to hand out the clickersScience is EverywhereWhat are we going to do in ChemistryPhysical and Chemical PropertiesSolids.

Science is EverywhereSI unitsYes, its true, you are going to be taught metrics AGAIN.Really, its not my faultGotta know the base units

Science is EverywhereConvert 15 grams to milligramsWatch me do it

Science is EverywhereConvert 25 centiliters to hectolitersWatch me do it

Science is EverywhereNow you do it.Grab your clicker and lets go!

2 hectacres to acres2000.12) 1500 meters to kilometers1.50.15.79 meters to centimeters5790.14892 milligrams to grams4.8920.16.1 kiloliters to liters61000.1Science is EverywhereBase units and derived unitsWhats the difference

Science is EverywhereFactor label for conversions (dimensional analysis)Have you seen this before??10 dollars into quarters

Science is EverywhereStill easy, doing something you know250 meters into kilometers (using factor label method)

Science is EverywhereMinutes in a year?

Science is Everywhere30 m/s to km/hr?

Science is EverywhereGrab your clickerNow you do the next one36 g/ml to kg/l360.1100 km/hr to m/s27.780.1I have a good grasp on converting?Strongly AgreeAgreeNeutralDisagreeStrongly Disagree

Science is EverywhereBest way to organize data?This is for all you visual people!

Science is EverywhereSlope of the line?How do we find it?Science is EverywhereRemember the Scientific Method??Yeah, yeah, moving on (three more slides and it will return)Using modelsDraw me a pictureMore on this to come..

You Got Skills?Lets See!!You Got Skills?Science begins with curiosity and often ends with discoveryMany items are discovered by mistake

You Got Skills?Scientific MethodObservationsHypothesisTest hypothesis (revise if needed)ConclusionsTheoryLawYou Got Skills?HypothesisTheoryLaw

You Got Skills?Using modelsWhat is a model?Is it really complicated??Does it need to be some complicated thing?You Got Skills?Scientific notationWhy would you want to do this??How often am I really going to need this?

You got Skills?Scientific Notation examples..You got Skills?How to put it in my calculator?

6.02 23 = 6.02 x 1023

2ndEEIts above the number 7You Got Skills?Significant FiguresNot that significantMostly used in chemistryMust be aware, online homework answers use six digit ruleYou Got Skills?Finding Arealength x widthSquared unit (cm2, m2)Units must match!You Got Skills?Finding Volumelength x width x heightSquared unit (cm3, m3)Units must still match!You Got Skills?Try these example problems. Note: Now we will be timed for each questionFind the area of a rectangle that is 20 cm on one side by 30 cm on the other.6000.1Find the area of a polygon that is 13 cm on one side and 7 cm on the other910.1This particular polygon is 90 cm on one side and 1.2 m on the other.108000.1What is the volume of a regular solid that is 10 cm x 5 cm x15 cm?7500.1Last one of these. What is the volume of a 25 cm cube?156250.1You Got Skills?What happens if you dont have a regular solid?Means you cant measure l x w x hWhat could you do

You Got Skills?Volume by displacementPlace in a graduated cylinder filled with waterMeasure the change in volumeYou Got Skills?How can I use this to find density you ask..What a great question

You Got Skills?

You Got Skills? D =

m =

v =

Watch your unitsYou Got Skills? If I gave you a rock, a graduated cylinder, water, a scale, and a ruler, how could you tell me the density of the rock?

(Put your hand down Jordi and give someone else a chance to answer)You Got Skills? Go back now and pick up Scientific method and scientific notation.
