Due to some struggles in my class, plus I found out that Mr. Niehaus's test is now on Tuesday, I am moving our Unit 1 test to Wednesday.
Lab Journals will be handed back on Tuesday and discussed, and we will have some sort of fun review.
*If you use the online book (not downloaded on your flash drive), I had to change the access code; it was given in class today to write inside your notebook (or wherever)*
Yesterday in class we finished notes on graphing (see older posts), had some density demonstrations, and worked on some practice conversion problems. Most classes had time to prepare/discuss plans for today's Elastic Rebound Inquiry Lab.

Quiz today... and Graphing notes, HMWK for Friday
Today's quiz went pretty well for most. Grades will be entered tonight and you will get your quiz back tomorrow.
We did hand-grade the quiz so you could get immediate feedback.
Notes on graphing (we'll finish tomorrow)
HMWK due Friday: p. 879#1-10
Exam Tuesday: Unit 1: Measurement and Density!

HMWK due Friday: p. 879#1-10
Exam Tuesday: Unit 1: Measurement and Density!
Unit 1 Assessment categories: (I expect you to perform well in all of the
following areas)
1. Why is SI important/valuable? What are drawbacks of SI? (vs other measurements)
Use SI prefixes to represent quantities and convert between
measurements:
2. Express (some measurement) in:
a. (some SI unit) b. (different prefix, same
unit) c. “ “
3. Determine the density of the object provided to you. Relate this item’s density/ characteristics
relative to others.
4. Use tools to measure real items accurately and precisely,
using appropriate SI units.
5. Design or critique an experiment using your understanding
of science and experimentation.
6. Use density values to determine the volume or mass when
one is unknown. Ex. Find mass of 1 liter
of water.
7. Represent results from an experiment visually with an
appropriate, correct, complete graph.
8. Use a graph to interpret data, explain observations, and
predict other events.

Exam next Tuesday! Quiz tomorrow.
HMWK for tonight? Study / Review. Work the problems at the end of the chapter and also at the end of the book, review readings as well. I have an answer key to any book problems in my teacher's edition that you may access anytime, including before or after school.
Today: more conversion practice with real-world word problems...
and
A scientific method and conversion practice WS

Density Lab due tomorrow!
Today:
Turn in homework (p. 32)
Warm - up (group work): Grass (if you're watering it) grows at a rate of 3 cm/week. How fast is this in MPH? Observe significant figures in your final answer.
Finish Density Notes - specifically some algebra things.
Discuss algebra shortcut - limitations.... I've seen some bad work already as a result (maybe I shouldn't have shown you yet)
Discuss points for lab - what "optional" means
Readings and discussion: Bias

Density notes, activity, HMWK for Thursday
Today in class:
Turn in homework
Finish conversion practice worksheet
Notes on Density
Practice measuring density of an object
Density activity - challenge if time allows.
Homework due Thursday:
Read p. 22-26
p. 26#1,2b,5
p. 34#4,6,10
Bring Lab Journals Thursday and Friday!

Friday: Measurement, HMWK for next week... Density
Today in class we'll finish yesterday's measurement activity WS and discuss/share answers, as well as measurements on some of you - records put on the board.
We'll also try to match prefixes with values such as 10, 1/10, 100, 1000 and deci, kilo, micro, etc... :)
Books passed out today.
We may start notes on Density and have some fun activities and demonstrations mixed in as well Friday and Monday.
Homework: will help give more background for density and wrap up some of the measurement topics we've reviewed so far:
Due on Tuesday: Read p. 14-21 in the text; work p. 21 #1,2,4,5
Recommended extra problems:
P. 32 (chapter review) problems 2,4,9, 12-17 (except 15), 23,24, 27-29.
If you have any questions, you may come in and ask or see my teacher's edition to the textbook anytime!
On Tuesday in class we will go over answers to the homework, try some conversions between units, and see density demonstrations.
September 5th (Thursday in Science Club) we will try to measure a HUMAN's density! Come and see, and bring extra clothes or a swimsuit! :)

Welcome to FHS!
In this post:
a note to this year's incoming Freshmen
details about class - required materials, this web page, optional assignments
your first homework assignments
I am very excited to have you in my class this year! A few notes about the class that may be helpful:
-Book assignments are intended as background; read the assigned reading and try your best on homework problems. If you haven't done the reading, you may find yourself lost in class.
-If you need help, ask! I am around before and after school, plus most of you probably have Facebook accounts. Find "Mr. Freeman's Classroom" and get updates from class, links to this page, and ask questions on there. If you don't get a homework question, ask online and I bet one of your classmates will likely answer it before I do.
-Homework assignments are ALWAYS given with 2 days' notice. If you can't get work done by the assigned time, a 50% late penalty will be assigned and you can still turn it in one day late. After that, there will be no credit assigned unless I am contacted by your parent to explain why you can't finish homework within 3 days.
-Have fun! I will try to get you involved as much as possible; hands-on demonstrations and activities are a great way to learn science.
This page will be updated daily as a resource for you and your parents. Links to additional assignments (optional assignments) that you may do to buffer your grade, copies of upcoming notes and handouts, homework listings, and all sorts of fun things will appear here. I do try to post links to this page on my Facebook page too so you can keep informed.

This year's first stuff to know:
Lab Journals: We will do lots of labs in this class; one official lab per unit will go into your lab journal. You will need one by Friday, August 23. This should be a bound composition book-type journal, with graph paper. I sell these for $2.15 and have several available. If you continue on to Honors Chemistry next year, you can re-use your graph paper lab journal. If you aren't going into Honors Chemistry, I am flexible on the journal you use and I can even give you graph paper to glue in when you need it. Lab reports must be done in these journals, in pen, according to guidelines, but if not done properly, your grade will not be penalized; the lab will not be graded at all. The same goes if you are absent and can't make up a lab activity... this does weight your test and homework grade more heavily though!
Online textbook: On your syllabus there are instructions to access the online textbook. Try it out and you can get a head start on homework - read p.14-21 and work problems p. 21 #1-5, Due Tuesday, Aug. 20
Digital copy of the textbook: Bring in a flash drive to school and I will copy the textbook for you - we have lots of CD copies but they don't always work well. (I will need a few volunteers to try this since we are short on texts)
Syllabus - sign (Parents) and return by Friday, Aug 17 please. You must have this signed and returned to participate in labs
1st assignment: List of 10 metric measurements + Metric vs. Standard argument- Due Friday, Aug. 16:
--> Argue for the use of either Metric or Standard units' measurements of a particular item.
-->Find ten items around the house and record the metric, or S.I. (International System) units of measurement on their labels. Units should be based on liters, grams, or meters mostly, and many will use a prefix, like mL for milli-liters or cm for centi-meters.
Examples:
Item Measurement
1. Head & Shoulders Shampoo 400 mL
2. Canned corn 375g
3. Aluminum Foil 7.5 m^3
Argument example: Yards make more sense than meters to me because there are 36 inches in a yard, which is easier to remember than 100 cm in a meter.
