Course Description
Physical Science is a combined course of Physics and Chemistry. This course develops a
basic understanding in Physics and Chemistry. The concepts and skills developed are
essential for basic literacy and further science study. The course includes learning
scientific facts, principles, and concepts and terms that will help students understand and
interpret natural and scientific phenomenon. Study of Physics begins with the study
of Motion, then Forces, Energy, Electricity and Magnetism. Study of Chemistry discusses
about the Matter, Properties of Atoms and Chemical Bonds and Chemical Reactions.
Students who successfully complete this course will attain the strong basis in Physics and
Chemistry for their higher studies.

Teaching Strategies

Topics are presented in a clear and effective manner. Power point presentations and
resources from the internet also will be used to enhance teaching. Problem solving is a
part of teaching Physical Science. Students are encouraged to take part in discussions and
they are always motivated to ask questions to clarify their doubts. Students are advised to
take down class notes which help them to learn and understand better and have them by
their side when they learn the topic at home. Every student is expected to leave the class
with proper understanding of the concepts and ideas.

Activities and discussions will be given to students to help them discover science
concepts through inquiry and to apply the knowledge they’ve constructed to their own
lives.

Students learn better and more effectively if they are able to see with their eyes, feel with
their hands and conceive ideas in their mind. Lab activities are emphasized to help
students in their learning.

Projects will be given and the students may be asked to do them individually or in
groups.
Student Activities

Students are encouraged to take part in discussions and other group activities. They will
help their peers through cooperative learning.

They will present their projects at the end of every quarter. They will do lab activities for
every topic to reinforce learning.

They will decorate their bulletin board with the posters and charts related to the current
topic.

Assessments

Students will be assessed with Quizzes after every section.

Pop Quizzes will be conducted occasionally.

They will be given chapter test after the completion of every chapter.

Quarter exam will be conducted at the end of each quarter.

Projects, Lab Activities, Homework, Seatwork and Portfolios will also be assessed.

CLASSROOM RULES

♦ Be punctual in attendance.

♦ No food or drink is allowed inside the classroom.

♦ Only bottles with lids are allowed to be on your table

♦ Your table should be neat and clean always.

♦ Throw your garbage into the allocated garbage bins.

♦ Push your chairs back when you leave the classroom.

♦ Take the necessary materials with you when you come to the class.
  You won’t be allowed to go back to your class to get your things once the lesson
  starts.

♦ Speak in English always.

♦ A record will be maintained to check on this. If you speak 5 times in any
  language other than English, 1% of your quarter grade will be deducted.
  This record will be checked at the end of every quarter and your grades will
  be deducted accordingly.


HOMEWORK RULES

 All science assignments must be turned in on the day they are due. Assignments should
  be on teacher’s table before 8:00 a.m. If not, that will be considered as late work.

Late homework will be graded by taking proportional deductions. If the
 homework is late for a day, 10% of the score will be deducted. If it is late for 2
 days, 40% of the score will be deducted. If it is late for more than 2 days, they will be
 asked to attend Project I.

 Students who are absent with good reasons will be allowed to make up the missing
  work without any deductions.

 Copying is strictly prohibited. In case of copying, both students will be given zero.
