Here are the main parts of the eye and their functions:
- Cornea - The clear front part of the eye. It focuses light into
the eye.
- Iris - The colored part of the eye that controls the size of the
pupil and the amount of light entering the eye.
- Pupil - The black opening in the center of the iris. It adjusts to
the amount of light. In bright light, the pupil becomes smaller. In
dim light, it becomes larger to let in more light.
- Lens - A clear structure behind the pupil. It helps focus light
onto the retina. It changes shape to focus on near and far objects.
- Retina
Science is the knowledge we get from study, experiment and observation. We use science to make our lives easier through inventions like light, pencil, car, medicine, and computers which have been created by scientists and inventors through the scientific process. Science and the work of scientists through history have led to many important inventions that have improved people's lives.
This document provides an overview and lesson plans for a science curriculum on matter for third grade students, including lessons on solids, liquids, gases, properties of materials, and safety. The curriculum covers topics such as describing characteristics of different states of matter, changes in materials, living things and their environment, and earth and space. Detailed lesson plans provide objectives, procedures, and background information for teachers.

The lessons include identifying sounds in the environment and from transportation, animals, and musical instruments. They also cover the English and Filipino alphabets, beginning letters of words, and elements of a sample story called "The Tenth Hen." Students are asked to listen to sounds, identify objects, answer questions about the story, and learn sight words. The goals are to help students gain skills in phonics, reading, and understanding basic story elements.
K TO 12 GRADE 3 LEARNER’S MATERIAL IN SCIENCELiGhT ArOhL
This document appears to be a draft of a grade 3 science textbook. It includes an introduction, acknowledgements, table of contents, and the beginning of the first unit on matter. The unit covers the three states of matter - solids, liquids, and gases. The first chapter focuses on solids, their characteristics like color, shape, size and texture. It includes activities for students to observe and describe different solids. The document provides structure and content for the textbook but is still in draft form.
The document provides a detailed lesson plan on teaching students about renewable and nonrenewable natural resources. The objectives are for students to identify renewable and nonrenewable resources, describe how living things benefit from the environment, and protect natural resources. The lesson involves grouping students to put together picture puzzles of resources, identifying resources as renewable or nonrenewable, and discussing the importance of conserving resources and reducing pollution. Renewable resources include sunlight, water, air, plants and animals. Nonrenewable resources like petroleum and coal must be used wisely since they cannot be replaced within a short time.
Detailed Lesson Plan in Science and Health grade 3janehbasto
This lesson plan outlines a preschool science lesson about the parts of the body. The objectives are for students to identify different body parts, understand their importance, and know their functions. The teacher will use pictures and a chart to show the body parts and discuss their functions. Students will practice identifying parts in pictures and matching parts to their functions. Their understanding will be evaluated by identifying and describing pictures of different body parts. As an assignment, students are asked to bring pictures of body parts to show the class.
