### Transcript

• 1. NotesNotes
• 2. The student will: Make accuratemeasurements using theInternational System ofUnits (SI-metric)
• 3. The student will: Select and use appropriatetools for gathering data
• 4. The student will:Use mathematical conceptsto collect, analyze and reportdata
• 5. The student will:Investigate and determinephysical properties of matter
• 6. The student will:Calculate mass, volume ofsubstances
• 7. Physical PropertiesMassVolumeMeanMedianModeRange
• 8.  The traits that canbe easily observedby using the fivesenses Color – Red, blue , etc. Texture – Smooth or rough Shape – Round, jagged,square etc. Conductivity - Allows heat orelectricity to pass Size – Large, small Luster - Shiny or dull Hardness – Soft - hard
• 9.  The amount of matterin an object orsubstance▪Measured with atriple-beam-balance▪Measured in grams(g) or Kilograms (Kg)
• 10.  The amount of spacesomething takes up Liquids are measured inmilliliters (mL) Solids are measured in cubiccentimeters (cm3)▪ For a regular solid such as a cube , measurethe length (l) the Height (h) and the width(w). Then multiply l x h x w to get thevolume▪ For an irregular solid use the waterdisplacement method using a graduatedcylinder
• 11. Mr. Kershes ……….NOT!
• 12. The average in aseries of numberswhen they are firstadded and thendivided by thenumber of addends6+8+5+4+2+10 +7= 4242/7 = 6Mean = 6
• 13. The middlenumber in a seriesof numbers whenthey are put inorder from lowestto highest 6, 8, 5, 4, 2, 10 , 7 2, 4, 5, 6, 7, 8, 10 6 is the mediannumber
• 14. The mostfrequentlyrepeatednumber/valuein a series ofnumbers2, 4, 5, 6, 6,6, 7, 8, 106is the Mode
• 15.  The differencebetween thehighest and thelowest numbers ina series of numbers It can be written asLowest – Highest oras the numericaldifference betweenthe lowest andhighest numbers. 2, 4, 5, 6, 7, 7, 7, 8, 10▪ Range Lowest t oHighest  2 – 10▪ Range difference =8
