Hon Chemistry 8-20-26 Calculating with Sig Figs & Scientific Notation

Ms. Skinner — Fri, 21 Aug 2026 19:33:35 +0000

Hon Chemistry: Today we wrapped up the discussion of sig figs – using them in calculations, and also had a quick review of scientific. How are you doing with this? Are you ready to apply what you’ve learned? Good times!!

What about that SI Quiz on next week? Make sure you are actively studying these things:
Everything in the SI Prefixes chart: symbol, exponent, meaning, and how many in one of a larger one. For example, 1 L is how many cL?
SI fundamental and derived quantities and their symbols
SI fundamental and derived units, their symbols, and the quantity they measure
SI standard unit for all the quantities

Chemistry 8-18-25 SI Measurements, Pt 2, Derived Units

Ms. Skinner — Tue, 18 Aug 2026 21:02:41 +0000

CHEMISTRY: Great job with fundamental and derived units! Now on to using what you know!

UPDATE: the cLAB: The Physics Aviary: Measuring Games has been moved to tomorrow. Your only homework is the book homework. Make sure you follow the directions from last week for doing and turning in book homework.

BTW – How are you doing with getting ready for the QUIZ on SI prefixes, Quantities & Units? It’s a ton of important info to know for the rest of the year. Practice, practice, practice it and don’t wait until the last minute!!

Physics 8-18-26 Data Relationships & A Look at Some Ch 1 Homework

Ms. Skinner — Tue, 18 Aug 2026 19:55:34 +0000

PHYSICS: Here’s a look at the homework from the last of chapter 1. May seem trivial now, but oh my how you’ll apply all of this for the rest of the year! Also a very quick review of data relationships and interpreting graphs.
