__**9-3-13 Tues**__ Welcome back to another year of middle school science!

__**9-4-13 Wed**__ Emergency procedures and classroom matrix. Introduce Science Starters!

__**9-5-13 Thur**__ What do you recall about metric measurement from last year? "Metric Scavenger Hunt"!

__**9-6-13 Fri**__ "Conversion Practice" and "Conversion Challenge"

__**9-9-13 Mon**__ SI (metrics), perimeter, area, volume. More practice with "Metric Test #1"

Practice, practice, practice with "Metric Test #2".
 * __9-10-13 Tues__**

__**9-11-13 Wed**__ "Metric Measurement Quiz" today. This one isn't graded.....YET

__**9-12-13 Thur**__ Come on down! You're the next contestant on the "Metric Estimation Game"!

__**9-13-13 Fri**__ Begin practicing metric measurements with the "Using Metrics Lab".

__**9-16-13 Wed**__ Swearing in for all competitors in "The Metric Olympics". We will spend the next two days completing all metric Olympic events.

__**9-23-13 Mon**__ Here is our review of density. Your assignment for Monday is to read the "Calculating Density Lab" so you are ready to begin.

__**9-26-13 Thur**__ Metric Test today.

__**9-27-13 Fri**__ Starting discussion of Dimensional Analysis.

__**10-3-13 Thur**__ Enough Dimensional Analysis! Moving on to a review of the Scientific Method. Fill in the Blanks Scientific Method worksheet due for tomorrow.

__**10-7-13 Mon**__ Here is the power point that will guide us through the scientific method.

__**10-21-13 Mon**__ In a controlled experiment you change only one thing at a time. The part of the experiment that you purposefully change is the manipulated variable (independent variable). The part of the experiment that you measure or observe is the responding variable (dependent variable). All other variables should be controlled. the standard you use for comparison is the control or control group.

__**10-22-13 Tues**__ Data are the observations and measurements made during a scientific investigation. Interpreting data is the process of finding meaning in data by looking for patterns and trends. Here is today's homework:

__**10-23-13 Wed**__ Today we get to see the scientific method in action. We begin viewing an episode of Mythbusters, paying particular attention to how they adhere to the scientific method in their investigations. While watching, this is the guided viewing worksheet you will attempt to complete.

__**10-24-13 Thur**__ Finishing up watching the Mythbusters episodes. Don't forget to complete the accompanying worksheet. I will be collecting it!

__**10-25-13 Fri**__ Finally, an opportunity to use the scientific method. Today we start our Mobius Lab. Working with your lab partner you will practice making writing a good hypothesis, analyzing data, and drawing conclusions. Start today and finish Monday. TEST TUESDAY.

__**11-4-13 Mon**__ How did atomic theory develop and change? You will discover the answer to that question over the next two days by completing the [|Webquest: Atomic Theories and Models]. The links provided will take you to the information needed to complete the webquest. You will also find some of this information in your textbook. **THIS MUST BE COMPLETED BY THE END OF CLASS TUESDAY.**

__**11-5-13 Tues**__ In order to complete the "History of the Atom Timeline" on the last page of your webquest, you will need to follow this link: [|Atomic Structure Timeline]. The link on your worksheet will NOT take you to the correct page!

__**SKILLS RECOVERY PROGRAM** **1ST QUARTER**__

During the second half of the quarter, we studied the scientific method. To further your understanding of that process, you will complete the website found here: [|Please Teach Us the Scientific Method]. You will be looking at the Introduction page. Read through this page in it's entirety. When done, click on the next bullet on the task bar at the left, "Task". then read that page completely. PLEASE NOTE THAT YOU WILL **NOT** BE WORKING IN TEAMS. THIS IS DONE INDIVIDUALLY! Continue to the "Process" page and read these directions. You will be prompted to print off certain pages that you need to complete will working through the webquest. FOLLOW ALL DIRECTIONS IN ORDER. It's that simple. When you are done, you will create a powerpoint (a good, readable one, that can be printed for me to see).


 * If you have any questions, your SRP teacher should be able to help you. If not, see me during the day.

Are you ready for your introduction to "Dynamite Don"? In this video he will help explain the history and usefulness of the Periodic Table. Try to fill in as much of the "Response Page" as you can while you watch **. [|World of Chemistry -- Episode 7 -- The Periodic Table] **
 * __11-15-13 Fri __**

Follow these links to the websites listed on your handout "Periodic Tables Online". Follow the directions on the handout to help you find the information needed to complete the worksheet. Don't worry if you don't get finished today.

 * 1**st hour students watched a Ted Talk today featuring Ben Saunders, the youngest man to ski solo to the North Pole. You can watch his telling of the expedition here**:[|Ben Saunders: Why Did I Ski to the North Pole?]**

In that video, he describes his next adventure -- to ski across Antarctic to the South Pole and back in 2013. As luck would have it, he is on that journey now! He and his fellow explorer are on Day 26 of their journey. If you are interested in keeping up with their progress, here is the link: **[|"The Scott Expedition"]**. Check their progress as they attempt to successfully complete the journey that Captain Scott and his men could not.


 * __11-22-13 Fri__**
 * To introduce the concept of ionic bonding, watch this short tutorial:** [|What are Ionic Bonds?]**. Don't bother pausing it when asked to. Just let it play.**


 * Then, to reinforce what you learned in that video, watch this one next:** [|The Ionic Bond Song]**. Enjoy!!**


 * __1-14-14 Tues__**
