Believe it or not, depending on the type of Soda, some will float in water, while others will sink. This is because their density (D= Mass/Volume) is either greater than (sinks) or less than (floats) the Density of water (1.o g/ml). Today we’ll be determining the densities of  different types of soda in the Lab.

The rest of the week and into next we’ll be reviewing for the Unit Test which will be NEXT WEDNESDAY. Here are the topics we’ve covered:

• Making Measurements with Uncertain Numbers
• Accuracy, Precision, & Error
• Significant Figures
• Scientific Notation & Calculations
• SI Units & Conversions
• Derived Units (Density)

Start preparing Now! Use your notes, practice problems & answer sheets, voice thread, and study guides to get started!

Or, International Standard Units are what we’ll be covering as a part of our last notes for Unit 1. The Voicethread link is available on the Notes page along with the PDF version of the notes… which can be found using this link as well.

We’ll be in the Lab tomorrow! Test Next Wednesday!

I’ll be out today, and trust me I’d much rather be with you helping you through scientific notation. Instead, I’d like you to get the handout from the cart (also available below) and read through the 2 parts.

Part 1: Use this link- Scientific Notation Generator – complete 10 scientific notation problems. If you get any wrong, please write them down on your handout.

Part 2: Complete the Practice problems to the best of your ability.(Practice Problems PDF) As you work, you can check your answers, and follow the steps, on this answer key- Scientific Notation Practice Answer Key

First, make sure you jump on power school and check your quiz grade. A few people are yet to take it so I cannot pass them back just yet. However, today in class I’m going to give everyone the opportunity to go over some of the problems and get some missed credit back. Remember, I’m here to help you succeed, not hold you back.

We’ll also begin discussing Scientific Notation and doing some practice problems. After which we’ll be reviewing the concept and doing some practice problems online. The link is listed below.

Remember if you have questions, don’t hesitate to email or tweet me and I’ll do my best to get back to you in a timely fashion. Have a great Thursday!

When you complete the quiz today, you will need to open your version of the text to the start of Chapter 3. There you will find 2 pages of info on Scientific Notation. We’ll be covering this for the next 2 days and I would like for you to familiarize yourself with the concepts before we start discussing as a class. Below is a link to the handout that accompanies the text. Please fill it out as completely as you can before class tomorrow.

I realized after yesterday’s classes that I’ve been pushing my students a little too hard and going through material a little to fast. So, to that effect we’ll spend the whole day reviewing and I’ll be taking a few items off of the poster and quiz requirements (Scientific Notation & Multiplication/Division of Sig Figs).

The Quiz is still tomorrow and will be based on the Review Problems we worked on today. The review posters will now be due Wednesday by the end of school.

Today we’ll be getting together with a partner to create a Review Poster on the topics we have covered thus far. The poster is worth 25pts and is due Tuesday before 11:59pm. That’s right, this is not a construction paper and markers kind of review poster… you will be using your iPads to create and share your posters. There are criteria and requirements you must follow you can download the handout that goes with the assignment below or on the Semester 1 Docs page. Have fun, be creative, and above all REVIEW because you will have A QUIZ ON WEDNESDAY and your Unit Test is right around the corner too!

Review Poster Handout & Rubric

For the last week you have been relying on the teacher and your fellow classmates to get notes, complete assignments, and otherwise function in the classroom. Today, we will begin implementing part of the independence we discussed on the first day of class. After you complete the warm up you’ll be going over new information on Significant Figures using Voicethread. Follow the directions below and ask questions when they arise.

1. Download the handout from the Docs page, from this link, or get the hard copy from the cart.
2. Open your Voicethread App. Click ‘Search’ at the bottom. Then type in ‘Kubuske’ as the key word.
3. Click on the’ Significant Figures’ presentation.
4. Follow the directions on the presentation & notes taking notes in Cornell style.
5. When you’re finished, complete the practice problems.

Remember, we’re on shortened periods for the Welcome Back Assembly this afternoon so don’t waste time.

Good Luck and hope to see you at Ben Davis supporting your team tonight!
