Convection Currents

Here are the two videos, which we watched in class, in case you wanted to see them again.




Below is a link to an animation that shows convection currents at work in the mantle.  The blue areas show the cool, denser rock sinking towards the core and the yellow and orange areas show the hotter, less dense rock rising towards the crust.

Mantle Convection Current Animation

Another simple animation of convection and the resulting movement of the plates.

"Black Out Bullying" on Wed., Jan. 25th

Governor Deval Patrick has designated January 25^th as “No Name Calling Day” in Massachusetts to increase awareness of the devastating effects of verbal bullying, to encourage students to use positive language and pledge not to use hurtful names on this day, and to promote tolerance and respect for differences.

Please help spread the word and make this day a success by wearing black on January 25^th as a sign of our commitment to “Black Out Bullying.” 

On this day, we will also take a stand against bullying by signing a banner that reads “I pledge to take a stand against bullying and name calling.”   This will be posted somewhere around the school.

If you are making a model for the project, please bring in any materials which you think you might need for tomorrow's class work period. 

Here is the project description, in case you left it at school.

Project – Travelling Inside Earth

You are now an engineer working for Fuezery Earth Corporation.  You are in charge of designing their new line of “Earth-Travel” vehicles.  Your goal is to draw or build a vehicle that can take 2 scientists to the center of the Earth.  (You may have to invent some new materials in order to do so.)  Don’t forget to include some scientific instruments so that the scientists can record important information about their trip!

Your job:

1)  Draw the outside of the vehicle that will travel to the center of the Earth.  You must have a GOOD SCIENTIFIC REASON for everything that appears on your drawing.  “It looks cool,” is not a good enough reason!!!

OR

1)  Build a model of the outside of the vehicle that will travel to the center of the Earth.  You must have a GOOD SCIENTIFIC REASON for everything that is part of your model.  “It looks cool,” is not a good enough reason!!!

2)  Label all the important parts of your project.  (If you are making a model, you may have to glue these on, or attach them in some other way.)

3)  On a sheet of paper or index cards, explain why you included each part of your vehicle, giving GOOD SCIENTIFIC REASONS. 

Sample sentence starters:

On my vehicle, there is a ________________, because...

I included ____________________ because...

The scientists will need to ___________________, so I have included…
