1. 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?

2. Directions: Copy the following Chart: 3 columns and 8 rows MeasurementTool/Formula to CalculateUnits PerimeterL + L + W + Wcm AreaL x Wcm 2 MassGraduated Cylindergrams WeightSpring Scalenewtons VolumeL x W x HCm 3 Volume of LiquidGraduated CylinderMilliliters (mL) Volume of an oddly shaped object Water displacement w/ graduated cylinder Cm 3 DensityD = m/vg/ml g/cm 3

3. How do we find the perimeter of something? Add the length of all sides together! 42 cm 15 cm

4. How do we find the area of something? Length x width 108 cm2 40 cm2

5. How do we find the volume of something? Length x width x height 125 cm3

6. Independent Practice Practice 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

7. BRAIN BREAK!!! Take two (2) minutes to relax your brain. Feel free to stand up and stretch (stay at your seat). BRAIN BREAK!!! Take two (2) minutes to relax your brain. Feel free to stand up and stretch (stay at your seat).

8. 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

9. Tool Normally Used in Science! Triple Beam Balance You can also just use a scale (that is what we will be using in class!!)

10. Digital Scale Used in Science Used in everyday life… Spring Scale

11. Graduated Cylinder Used in Science

12. 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 minutes Norms 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!

13. Answer the following questions: 1.What is a graduated cylinder used for? (list two reasons) 2.Calculate the following for the shape: A.Perimeter B.Area C.Volume 3. What is the main difference between mass and weight? Height: 4 cm Length: 6 cm Width: 3 cm
