Lesson 1:LengthT. Trimpe 2008 http://sciencespot.net/

English vs. Metric UnitsWhich is longer?A. 1 mile or 1 kilometerB. 1 yard or 1 meter1 mile1.6 kilometersC. 1 inch or 1 centimeter1 inch 2.54 centimeters1 yard 0.9444 metersLeft Image: ols/imagedemosm.aspx?picid 1167Right Image: http://share.lancealan.com/N800%20ruler.jpg

Metric UnitsThe basic unit of length in the metric system in themeter and is represented by a lowercase m.Metric Units1 Kilometer (km) 1000 meters1 Meter 100 Centimeters (cm)Click the image towatch a short videoabout the meter.1 Meter 1000 Millimeters (mm)Which is larger?A. 1 meter or 105 centimetersC. 12 centimeters or 102 millimetersB. 4 kilometers or 4400 metersD. 1200 millimeters or 1 meter

Measuring LengthHow many millimeters are in 1 centimeter?1 centimeter 10 millimetersWhat is the length of the line in centimeters? cmWhat is the length of the line in millimeters? mmWhat is the length of the line to the nearest centimeter? cmHINT: Round to the nearest centimeter – no decimals.Ruler: http://www.k12math.com/math concepts/measurement/ruler cm.jpg

Lesson 2:MassT. Trimpe 2008 http://sciencespot.net/

English vs. Metric UnitsWhich is larger?1. 1 Pound or 100 Grams1 pound 453.6 grams2. 1 Kilogram or 1 Pound3. 1 Ounce or 1000 Milligrams1 ounce of gold 28,349.5 milligrams100 kilogram 220 pounds

Metric UnitsMass refers to the amount ofmatter in an object.Kilogram PrototypeThe base unit of mass in themetric system in the gram (g)Metric Units1 Kilogram (km) 1000 Grams (g)1 Gram (g) 1000 Milligrams (mg)Click the image towatch a short videoabout mass.Which is larger?A. 1 kilogram or 1500 gramsC. 12 milligrams or 12 kilogramsB. 1200 milligrams or 1 gramD. 4 kilograms or 4500 gramsKilogram Prototype Image http://en.wikipedia.org/wiki/Kilogram

Measuring MassWe will be using triple beam balancesto find the mass of various objects.The objects are placed on the scale andthen you move the weights on the beamsuntil you get the lines on the right side ofthe scale to match up.Once you have balanced the scale, you add upthe amounts on each beam to find the total mass.What would be the mass of the object measuredin the picture? 300 70 3.4373.4 gTop Image: http://www.southwestscales.com/Ohaus Triple Beam 750 SO.jpgBottom Image: aboratory/graphics/triplebeambalance.jpg

Measuring Mass – Triple Beam Balance1st – Place the film canister on the scale.2nd – Slide the large weight to the right until the arm drops below theline. Move the rider back one groove. Make sure it “locks” into place.3rd – Repeat this process with the top weight. Whenthe arm moves below the line, back it up one groove.4th – Slide the smallweight on the frontbeam until the linesmatch up.5th – Add the amounts on each beam to find the total mass to the nearest tenth of agram.Click here to try an online activity.

Lesson 3:VolumeT. Trimpe 2008 http://sciencespot.net/

English vs. Metric UnitsWhich is larger?A. 1 liter or 1 gallonB. 1 liter or 1 quart1 fl oz 29.573 ml1 12 oz can of sodawould equalapproximately 355 ml.C. 1 milligram or 1 fluid ounce1 quart 0.946 liters1 gallon 3.79 litersIt would take approximately 3 ¾1 liter bottles to equal a gallon.

Metric UnitsVolume is the amount of space an object takes up.The base unit of volume in the metric system is the liter andis represented by L or l.Metric Units1 liter (L) 1000 milliliters (mL)1 milliliter (mL) 1 cm3 (or cc) 1 gram*Which is larger?A. 1 liter or 1500 millilitersB. 200 milliliters or 1.2 litersC. 12 cm3 or 1.2 milliliters** When referring to waterLiter Image: http://www.dmturner.org/Teacher/Pictures/liter.gif

Volume of LiquidsWe will be using graduated cylinders to find thevolume of liquids and other objects.Read the measurement based on the bottom of themeniscus or curve.HINT: make sure you are eye level with the level of thewater.What is the volume of water in the cylinder? mL43What causes the meniscus?A concave meniscus occurs when the molecules of theliquid attract those of the container. The glass attractsthe water on the sides.Top Image: a.gifBottom Image: http://morrisonlabs.com/meniscus.htm
