Dear Student:
This week we are going to begin a new Chapter. We will begin to explore the alternative energy resources that are so important to conserve our environment.
Energy conservation refers to efforts made to reduce energy consumption. Energy conservation can be achieved through increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from conventional energy sources.
These are some of the alternative energy resources we will be studying:
Solar Energy for heating water, generating electricity and concentrating solar energy to create fuel for your vehicles.
Biomass Energy Discover ways to use corn, corn stalks, wheat, pine cones, twigs,bark....to generate fuel to heat your home or drive your vehicle. The technology has been around for over 100 years. Basically, anything that decomposes or burns can be used to generate energy for your home or car
Wind Energy Another of the more popular alternative energy resources. Though not a reliable resource for every household, it is a viable option, depending on your location. Learn about the advantages and disadvantages of wind energy and see if it will be an asset for your energy needs.
Hydrogen You will see that this is my favorite. The must abundant element in the universe is Hydrogen. H2O. Ever think about driving your car on pure water? Apparently, it has been done.

Welcome to the Wonderful World of Science through the Earth Science Course for eighth grade. This course is widely described as a journey through Planet Earth and beyond our atmospheric boundaries. Students will study basic principles of Earth Science and will continue to use science tools, expand and build on their knowledge base, and work on their ability to comprehend science reading and to write clearly and coherently in the context of science.

Christmas Baskets
November 23, 2009
Dear Parents (Nursery – 12th):
As another holiday season nears, many of us will enjoy our time with loved ones and celebrate the joyous memories of the past year. As we give thanks for the blessings and gifts in our lives, we also have an opportunity to appreciate those people who make the American School outstanding, but who rarely get the recognition they deserve.
On behalf of all American Schools students, we would like to extend our gratitude to the maintenance workers, the bus drivers, the nannies and their families by preparing food baskets for them as gifts at Christmas. Students in each grade level are asked to contribute the following items:
Nursery Bar Soap
7th grade Ketchup
Pre-Kinder Detergent
8th grade Beans
Kinder Toilet paper
9th grade Cooking Oil
1st grade Rice
10th grade Maseca
2nd grade Pasta
11th grade Soup
3rd grade Sugar
12th grade Oatmeal
4th grade Tomato Paste
5th grade Cereal
6th grade Flour
Thank you for participating in this event, and for involving your children in the charitable activities of the American School. Please send the item with your child to his homeroom teacher (Pre School and Elementary School) and to their Class Advisors (MS / HS) before Friday, December 10. We hope that we can foster in all students a spirit of generosity and compassion which will, in the end, make our world a better place.
Sincerely,
Claudia Pereira
