Density Simulation
You will use this link to open up a density simulation to help you in exploring the density of water, as well as other objects. 

The Element Song with Tom Lehrer

Chemical Party Analysis

After watching this video again, embed the video into your own blog. List and describe the various interactions you see occurring at the party between elements. Who is attracted to whom? Who bonds with whom? Be very observant to the interactions, some are very quick and some are extremely obvious. Be sure that you include all of the molecular combinations you see and THEN research the chemical reaction online to figure out what compound they make and what it is used for.

Evidence of a Chemical Reaction

This week we will investigate what a chemical reaction is and how we know that one has occurred through the evidence of chemical changes. Embed each of the videos (listed as links below) on your blog as one single post titled "Evidence of a Chemical Reaction."

Beneath each video link, write what in complete sentences what you observed in that video. What evidence do you see in that video that indicates that a chemical reaction has occurred? What are the chemical changes that can occur during a chemical reaction? A pondering moment: What causes a reaction to end?
Finally, find a YouTube video on your own that shows a new chemical reaction and embed it into your blog.
Visit other classmates' blogs to watch their videos and comment on them the same way.

***BONUS: What can chemical changes tell us about the elements that are involved in the reaction?

WELCOME TO GRADE 8A!!!

Welcome back to all of you who I have taught last year and a BIG welcome to those who I have the honor of teaching this year.  I am expecting a great year ahead for all of us and I look forward to carrying out many scientific investigations with you too.  Good luck this year and remember...I am always just an email away or drop in to see me if you need ANYTHING throughout the year. 

Cheers!
