welcome learners 2017 – 2018

Welcome to my page. And my apologies for being late with the updates and quizzes posted. This first post for this school year will be your guide for this first semester on the lectures that our class will be having. The purpose of this post is to prepare you by reading topics in advance.

SUBJECT: Earth and Life Science.

Course Description: This learning are is designed to provide a general background for the understanding of Earth Science and Biology. It presents the history of the Earth through geologic time. It discusses the Earth’s structure, composition, and processes. Issues, concerns, and problems pertaining to natural hazards are also included. It also deals with the basic principles and processes in the study of biology. It covers life processes and interactions at the cellular, organism, population, and ecosystem levels.
