**Week 3 October 29-**September 2 Density and Volume**Objective**Today I will complete my test on density. So that I can demonstrate my gains on bench march SC.8.P.8.3 on density. I know I have it when I can pass my test 8 out of 12.**Density 1 SC.8.P .8.3**C= 0 H= none A= Test M= none, I will collect test P=Looks like students writing down school wide heading and bubbling I.D. number. Set folders up and don t write on test. Wait until test has been picked up. S=8 out of 12**Benchmark SC.8.P.8.3 Explore and describe the densities of**various materials through measurement of their masses and volumes. Know Understand Density Mass volume Calculating density, mass and volume Do How density involves the measurement of mass divided by volume Handout: Graduated Cylinder/Measuring Foldable: Temp. and Density Lab: calculate Volume and density Density Practice Homework (Video) column notes 7/7 Homework Online quiz HomeworkFSA p.83,84 Density Practice**Understanding Volume and Mass in**Relation to density Today I will practice how to measure volume and mass by calculating diverse problems. So that can explain the relationship volume and mass have with solving for density.

S=Check for success.**Temperature and Density 4 Tab Foldable**Text Even Evidence and Calculate Density and Temperature density of water Temperature Why is density important? p.202 From left to write label the unknown substances? Answer Question 1- 3 in Lesson 2 Check Write 3 details p.201 Answer question 1,2,3 p.203 p.201**Density and Temperature 201**Density is affected by temperature. Most substances become less dense as temperature decreases. Warm air rises and cold air sinks. Water becomes less dense as it becomes warmer but once it is a solid below 40C it becomes less dense.**Temperature and Density of Water p.201**1)When the water is at 40C 2)Since the arrangement of H20 changes and joins in patterns it becomes less compact and causes it to float. https://www.youtube.com/watch?v=UukRgqzk-KE 3)Habitats would be destroyed and ice would remain at the bottom cause damage under water.**Using Density p.202**Density can be use to identify substances.
