- Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms.
- Each pure substance has characteristic physical properties (for any bulk quantity under given conditions) that can be used to identify it.
- Do Now– Get out your science notebook and add to the Table of Contents- “Effect of Volume- p.59” (Right Side). Head page 59 properly with “Effect of Volume-Investigation-2/7/17.”
- Check/Review HW- Density Calculation (Take It Further) worksheet
- Period 4-Investigation– What is the relationship between mass and density for objects of equal volume? Model relative size and arrangement of atoms/molecules in metal, plastic, & wooden cubes. Complete conclusion regarding how the mass of cubes of the same volume affect density. Trim and tape data table as flip page to p.57 and tape graph paper as flip page to p.56.
- Driving Question Summary Table– Complete the Summary Table on pages 52-53 for the Effect of Mass Activity.
- Demonstration– Rods- Do rods with the exactly the same mass but have the same volumes? How do you measure volume using the water displacement method?
- Investigation– What is the relationship between volume and density for objects of equal mass? On page 59, set up Key Question, Problem Statement, Hypothesis, and Experimental Design.
