**Unit 1 (Scientific Skills), Day 8**

**Agenda** • Catalyst • Pass quizzes back • Mastery based grading • Dimensional Analysis Lecture • Break • Phase 2 of Project • Homework: Scientific Notation, Calculator Usage

**Catalyst** • Date: Mon 9/9 or Tue 9/10 • Reflect on the quiz from Friday • What do you predict is your grade? • Would this grade reflect what you have learned? • What would have been helpful to do better on the quiz? • What will you do in the future to demonstrate your learning well on assessments and projects?

**Pass Back Quizzes** • Period 1-3 Overall Average: 89% (B+) • Period 2-4 Overall Average: 84% (B) • Period 6-8 Overall Average: 89% (B+) • Period 9-11 Overall Average: 86% (B)

**It’s All About the Learning!** • If you got below a 100%, it is SUGGESTED that you come into office hours to go over the quiz • If you got below an 80%, it is MANDATORY that you come into office hours to go over your quiz • This MUST be done by THURSDAY! • Failure to do so results in a REFLECTION HOUR

**With Your Quizzes** • Habits of Mind vs. Essential Skills Grades • Look over them, determine if you MUST/SHOULD come into office hours • When finished, place them into the folders. Write your name large on the folder (First and Last). SLCs

**Mastery Based Grading** • On PowerSchool, starred (*) assignments are NOT included in your final grade. The included assignments are the ones labelled “OVERALL SCORE” assignments. Essential Skills and Knowledge (Physics Mastery) = 70% of grade Habits of Mind (Accountability, Quality, Collaboration) =30% of grade

**Mastery Based Grading** • What this DOESN’T mean: • Unlimited retakes on assessments • What this DOES mean: • Multiple opportunities to demonstrate mastery on an essential skill: • Homework, Quizzes, Exams, Lab Reports, Projects, POLs • Exams are cumulative, which means that the Unit 2 Exam will still assess mastery on Unit 1 material.

**Mastery Based Grading** • In Mrs. Larkin’s Class: • If you show higher mastery LATER, you receive the HIGHER score. • Example • On 8/30, you got a 7 on an assignment. On 9/3, you got a 9 on an assignment. • Your overall score would become a 9 • If you show lower mastery LATER, you receive the AVERAGE score. • Example • On 8/30, you got a 9 on an assignment. On 9/3, you got a 7 on an assignment • Your overall score would become a 8 (average of 9 and 7)

**Mastery Based Grading** • REASSESSMENTS are allowed only for the following: • Unit Projects • Improve and return the project within two weeks. Must have been turned in COMPLETED on time. • Lab Reports • Edit the report based on Mrs. Larkin’s feedback and return within two weeks. Must have been turned in COMPLETED on time. • Unit Assessments • Do test corrections during Mrs. Larkin’s office hours and return within two weeks. Test corrections don’t count for points; they only EARN you the ability to do a DIFFERENT form of the unit assessment. Must be done within 2 weeks.

**Bright Idea!** • If you have not watched the YouTube video, do so tonight so that you are prepared for the unit assessment. • If you don’t understand something, OFFICE HOURS!!!! • Remember, you will see the content for EVERY EXAM from here to the end of the year, since they are cumulative.

**Fraction and Units** • What is • 1/1? • 2/2? • 3/3? • 4/4? • cm/cm? • kg/kg? • mL/mL? • s/s?

**Basic Dimensional Analysis** • Activity • There are 3 triangles per 1 circle. • There are 2 circles per 1 square. • How many triangles are in 4 squares? • There are 4 triangles per 3 circles • There are 2 circles per 1 square. • How many triangles are in 3 squares?

**Basic Dimensional Analysis** • Dimensional Analysis: Comparing relationships between units • Conversion Factor: changes something to a different version • 1 ft = 12 in 1 mm = 0.001 m 1 kg = 2.2 lb1 s = 100 cs 1 L = 1000 mL 1 mL = 1 cm3 • Conversion factors can be written as fractions: A B A = B can be written as OR B A A WHY? B

**S.I. System** • International System • k (kilo-) = 1000 base units • h (hecto-) = 100 base units • da (deka-) = 10 base units • Base units = grams (g), meters (m), liters (L), seconds (s) • d (deci-) = 0.1 base units • c (centi-) = 0.01 base units • m (milli-) = 0.001 base units

**Break**

**Basic Dimensional Analysis** • Write the following in fraction form: • 1 ft = 12 in • 1 mm = 0.001 m • 1 kg = 2.2 lb • 1 s = 100 cs • 1 L = 1000 mL • 1 mL = 1 cm3

**Basic Dimensional Analysis** • What is 14 yards in inches? • Circle the starting measurement • Box the ending dimension (we’re solving for magnitude) • Conversion Factors I know: • ______ yd = ______ ft • ______ ft = ______ in START Multiplying Fractions Units END

**Basic Dimensional Analysis** • What is 12 kg/m in lb/m? • Circle starting measurement • Box ending dimension (units) • Conversion Factors I Know: • ______ kg = ______ lb START Multiplying Fractions Units END

**Basic Dimensional Analysis** • What is 3 kg/m in lb/cm • Circle starting measurement • Box ending dimension (units) • Conversion Factors I Know: • ______ kg = ______ lb • ______ cm = ______ m START Multiplying Fractions Units END

**Project: Too Fly For Junior High** • Phase 2 • Task: • Modify the best Phase 1 paper airplane in aSINGLE, MEASURABLE way. • Create 5 models that incrementally change this part. • Design and conduct an experiment using the scientific method to determine which of the 5 SIMILAR paper airplane models flies the furthest. • Constraints: • You may use computer paper, cardstock, glue, tape, paperclips, & staples.

**Phase 2 Design** • Lab Portion of Notebook. Date 9/9 • Write out the procedure (steps) for the experiment inPhase 2. Indicate the following: • Independent Variable, Dependent Variable, Constants, Control Group, Experimental Groups • Must be approved by Mrs. Larkin before you begin • Materials you will have: • Tape measurer, Ruler, Paper airplanes • Only the following may be used for airplane: Computer paper, cardstock, staples, paper clips, tape, glue, scissors • Ask if you need anything else

**Homework** • YouTube Video: Scientific Notation and Calculations. • Takes notes for quiz on Wed/Thu. • Bring calculator for quiz • Project Phase 2: Experiment procedure written. • Mandatory Office Hours (for those who got less than an 8 on one or more of the quiz questions)
