THIRD GRADE
Students in Grade 3 are becoming more aware of scientific concepts. They are active, inquisitive, and have a greater interest in their environment and an increased capacity for intellectual growth. Through varied and appropriate activities, third-grade students begin to develop a sense of where they are in their world. Teachers extend the natural inclinations of students to ask questions and investigate their world through an inquiry-based classroom environment. In this learning environment, students apply process skills, engage in hands-on activities, and participate in cooperative groups to conduct investigations that begin with questions and progress toward the communication of answers.
The development of critical-thinking and problem-solving skills is a major goal of the third-grade science program. In Grade 3, the study of science includes planning and implementing simple classroom and field investigations. Students describe the layers of Earth, including the inner and outer cores, mantle, and crust. They observe the force and motion of objects, identify weather phenomena, organize weather data into tables or charts, describe the life cycle of plants, and determine the effect of environmental conditions on plant growth and survival.
Cherokee County Schools: The documents for third, fourth and fifth grades are written to follow the basic order of the Alabama Course of Study: Science. Life sciences are listed first for two reasons. One is that the first unit in each grade level science book begins with the life sciences. The second reason is that the life sciences are sometimes more interesting to elementary students. This observation is the opinion of several elementary teachers. Of course, teachers should teach in the order that they wish as long as the state mandated mastery level standards are met.
The timelines listed are just a suggestion and can be manipulated as needed. Some standards may be harder to meet and need to be covered longer or returned to at a later time. And of course, some standards may be imprinted more into a group of student’s background knowledge and can be cut short.
Matching SAT objectives are noted where they fit in with the ACOS objectives. Many of the objectives are on similar matter, but may be worded differently or cover a slightly different aspect of the common subject. Several SAT objectives are not related to objectives on this document; therefore teachers must find time to review and cover those objectives that are not related.
Alabama High School Graduation Exam objectives are also listed where they overlap with ACOS objectives. Again, sometimes this overlapping is broad but will contain common subjects.
For most standards from the course of study, there are correlating textbook pages and activities listed. However, a few were not mentioned in the grade level books so there is nothing listed. Luckily, the Internet and ALEX are available to find endless information and resources that are needed. Proteacher.com is a great resource for science. Of the activities listed, most are found in the textbook and are simple to prepare.
