Do Now: Finish graphing your test grade and your class grade. MAKE SURE TO ALSO REFLECT IN THE REFLECTION AREA!! (Time: 6 minutes)

Guiding Questions:Test Graph Questions:• Why do you think

you go the grade on your test you did?

• What question(s) did you get wrong? Why?

• Did any of the test questions confuse you? Why?

Class Grade Questions:• Why do you have the

grade you have in class?• Have you been doing all of

your work?• Have you been letting your

behavior affect your work?• Do you understand the

science material you are learning?

Copy down the following Chart!Directions: Copy the following Chart: 3 columns and 8 rows

Measurement Tool/Formula to Calculate Units

Perimeter L + L + W + W cm

Area L x W cm2

Mass Graduated Cylinder grams

Weight Spring Scale newtons

Volume L x W x H Cm3

Volume of Liquid Graduated Cylinder Milliliters (mL)

Volume of an oddly shaped object

Water displacement w/ graduated cylinder

Cm3

Density D = m/v g/ml g/cm3

Perimeter

• How do we find the perimeter of something?

Add the length of all sides together!

42 cm

15 cm

Area

• How do we find the area of something?

Length x width

108 cm2

40 cm2

Volume

• How do we find the volume of something?

Length x width x height

125 cm3

Independent PracticePractice these problems on your own. You will then have time to check your answers with classmates, but try by yourself first! Make sure to include your units!! (Time: 3 minutes)

1. a. What is the perimeter? b. What is the area? c. If I told you the height was 6 cm, what would the volume be?

20 cm

25 cm2

150 cm3

BRAIN BREAK!!!

Take two (2) minutes to relax your brain. Feel free to stand up and stretch (stay at

your seat).

Important Definitions!!!

Mass - the amount of matter that makes up an object

Weight – measure of the force of gravity on an object

Volume – the amount of space an object takes up

Mass

Tool Normally Used in Science!

Triple Beam BalanceYou can also just use a scale (that is what we will be using in class!!)

Weight

Digital Scale

Used in Science

Used in everyday life…

Spring Scale

Volume of a Liquid

Graduated Cylinder

Used in Science

Group Practice:Each group will have a scale, spring scale and graduated cylinder. You will practice finding the mass, weight and volume of a liquid with these tools. You will have objects in the box of supplies that you will have to practice on. Write the name of the object and then write the mass and weight of it. Ms. S. will come around and fill your graduated cylinders with water so you can measure the volume of the water.

Time: 10 minutesNorms to keep the room calm and keep everyone safe:• We are always in our seats unless we are permitted to be out of

them (sharpening pencil, getting materials)• We always keep out hands to ourselves.• We are never purposely shaking the table trying to spill

someone else’s supplies.• We are never to shout across the room to another student; if

you wanted to speak with someone else, you should have chosen to work with him or her!

HomeworkAnswer the following questions:1. What is a graduated cylinder used

for? (list two reasons)2. Calculate the following for the

shape:A. PerimeterB. AreaC. Volume

3. What is the main difference between mass and weight?
