Unit 6: Solids, Liquids and Gases

Unit 6 pertains to the topic of Solids, Liquids and Gases. Get yourself in the right state of mind as it will be a quick 8- to 9-day unit. The first part of the unit should ideally be a real gas. Despite the rather ephemeral start, our feet should hit solid ground around the fifth or sixth day of the unit. The unit will be a mixture of conceptual reasoning and mathematics. A bit like Physics, there will be a good deal of algebraic thinking and formula-based problem solving. Some may think that the mathematics is just a phase and will quickly evaporate or go away; that's not the case as Unit 6 and subsequent units will be highly reliable upon mathematics and problem-solving.



Viewing Your Unit 5 Test

Beginning on Wednesday, February 12, students are welcome to come in to view their Unit 5 Test. You will be given your test, the test key, and some time to look and reflect. I will be present to answer questions.  I am available all lunch periods on Blue Days and before and after school on most Gold Days. Make arrangements to come in.


Pressure Concepts Concept Builder

You will be doing the Pressure Concpets Concept Builder in class as partners on Tuesday. Log in with both partners names - like Mac and Tosh.  Visit:



ChemThink - Behaior of Gases

We will be doing a ChemThink Tutorial in class on Monday. You will complete the Tutorial and the "Problem Set". We've done these before. If you no longer have your username and password, then create an account and be added to my class with the following access codes:

    Block 1: 76871419
    Block 2: 47664051

Lab SLG1: Pressure vs. Volume

Lab SLG1 will be completed using Google Classroom. You will work as partners. One student should grab the Lab Template and share it with their partner. Begin by putting both students' names on the front page of the document.


Lab SLG2: Pressure vs. Temperature

Lab SLG2 will also be completed using Google Classroom. You will work as partners. One student should grab the Lab Template and share it with their partner. Begin by putting both students name on the front page of the document. Use this Desmos Graph for data collection and plotting.


Graphical Analysis for Chrome

We will be using the Vernier Graphical Analysis app for some upcoming labs. Download it to your Chromebook from the Chrome Web Store. FREE!

Download Graphical Analysis.


Real STEM Students Do It With Desmos

The first two labs of this unit will involve the collection of data and the ultimate analysis using Desmos. You will plot the data in Desmos and utilize an appropriate function such as y = m•x + b or y•x = k or ... in order to best fit the line and generate an equation for the best fit line.

Visit Desmos.


Mr. H's Little Secret

Pssss.  Hey bud! I have a secret to share. Now that you know how to calculate the molar mass, here's a little cheat you should be permitted to use. It's called a Molar Mass Calculator and you will find several by following the links below. You type in the formula and it calculates the molar mass.


WebQC Chemical Portal (one of my favorites)

EndMemo (allows formula or name entry)

Environmental Chemistry (scroll to bottom)

Molecular Weight Calculator by Lenntech

or Google, e.g. molar mass Al2(SO4)3




FREE: A Chemistry Study Tip

Stretching out your studies over a lengthy period of time so that there are many "visits" of the material is far better than lengthier, less-frequent sessions of intense studies. So what's this have to do with Chemistry class? I'm going to tell you:

A little Chemistry each day helps. Your homework usually includes two WebAssigns - one is a "looking ahead" WebAssign in which you read about something that is coming up next. The other is a "looking behind" WebAssign in which you practice using something that we just learned in class. So why not do the "Looking behind" WebAssign on the evening of the Blue day - the day you were presented with the material. And then do the "Looking ahead" WebAssign on the evening of the Gold day - the evening just prior to when we cover the material the next morning. Hopefully that makes sense ... and it gives you a little Chemistry every day.  =SIGH=

Today in Class

>> Thursday, February 13 <<

Focus Question(s):
  • How can the volume-temperature relationship be used to predict the final state of a gas if given the initial state?
  • How can the pressure-volume relationship be used to predict the final state of a gas if given the initial state?

Activities:
  • Comments on Lab SLG1 and Lab SLG2
  • Discuss Gas Law Concepts (selected Qs, pp. 9-12)
    PV=k, V=k•T, P = k•T
  • Gas Law Calculations (selected Qs, pp. 13-17)
  • Discuss Chapter 13.2-4 Reading Guide (pp. 5-6)
  • ChemThink: Kinetic Molecular Model (pp. 21-22)
  • Labs SLG1 and SLG2 with your partner; submit to Classroom; then begin HW


Homework:   





Next Time in Class

>> Tuesday, February 18 <<

We will continue our discussion of gas law concepts and gas math.  We will do a Concept Builder or two and Lab SLG3.
