Science 400 is a basic elementary course intended to expose students to the designs and patterns in the physical universe. This course builds on concepts taught in Science 300, providing a broad survey of the major areas of science. Some of the areas covered in Science 400 include the study of plants and animals, ecology, work and simple machines, electricity and magnetism, properties of water and matter, weather, the solar system, and the different spheres of earth. The curriculum seeks to develop the students’ ability to understand and participate in scientific inquiry. The units contain experiments and projects to capitalize on children’s natural curiosity. The students will explore, observe, and manipulate everyday objects and materials in their environment. Collectively, this should help students develop and build on their subject-matter knowledge base. Upon completion of the course, students should be able to do the following: • Use their main senses for observation of the world around them. • Describe different uses for plants. • Discuss the differences among the ways that various animals act. • Understand how people are responsible for preserving and conserving nature. • Explain the different types of simple machines. • Describe an electrical current and how it relates to magnetism. • Demonstrate an understanding of the properties of water. • Observe weather and how it affects people. • Describe our solar system. • Discuss the three different spheres of the earth and how they interact. • Explain the changes in seasons and time.
