UNIT 1: Living Things and Their Environment
Introduction
At this point, students have already learned in Grade 8 how the body breaks down food into forms that can be absorbed through the digestive system and then transported to each cell, which was on the other hand discussed in Grade 7 to be the basic unit of life. The learners have also discovered that cells divide to produce new cells by mitosis and meiosis. They have understood that meiosis is an early step in sexual reproduction that leads to variation. Students have been introduced to genetics to be able to appreciate evolutionary differences among species. Learners have also found out that biodiversity is the collective variety of species living in an ecosystem, and by studying the ecosystem; they have come across the various cycling of materials and energy transformation.

All modules in Grade 9 Unit 1-Living Things and Their Environment present student-centered activities that will allow the learners to discover and develop concepts that they may consider useful to their everyday life. At the end of each lesson, key concepts are provided for the students to grasp ideas and information that they will remember even after they have left school. Instructional activities are designed to build up the students’ knowledge, understanding, skills, and ability to transfer learning. The modules generally use authentic assessment for the students to perform real-world tasks demonstrating meaningful application of essential knowledge and skills.
There are four modules in this quarter, namely:

Module 1: Respiratory and Circulatory Systems Working Together with the other Organ Systems
Module 2: Heredity: Inheritance and Variation
Module 3: Biodiversity and
