Day Thirteen Overview

Day Thirteen Overview

- finished the notes in the Skills and Methods Note Packet
- demonstrated what the relationship between Density and Buoyancy looks like
- used a web simulation at http://phet.colorado.edu/sims/density-and-buoyancy/density_en.html to demonstrate to the students that density does not change under normal conditions
- no matter how large or small a piece of material is, the Density of that material is always the same
- I then told the students that "i lied" and that there are two things that can change the density of a material ... pressure and temperature
- showed the students a web simulation that demonstrated the motion of molecules as they heat and cool at ... http://phet.colorado.edu/en/simulation/states-of-matter
- completed an in class activity called "Mystery Object Density" where the students used the web simulation at http://phet.colorado.edu/sims/density-and-buoyancy/density_en.html to make measurements and determine the Density of mystery materials
Mystery Object Density
- worked on a worksheet where the students just solved for Density
Solving just for Density

Homework

- read Chapter 2 in the textbook and answer all of the review questions at the end of the chapter (due 10/3 for Red Class and due 10/4 for Orange and Green Class)
- finish the Mystery Object Density Sheet if not already finished in class
