A very comprehensive introduction to electricity, magnetism and optics ranging from the interesting and useful history of the science, to connections with current real-world phenomena in science, engineering and biology, to common sense advice and insight on the intuitive understanding of electrical and magnetic phenomena. Slightly more advanced than standard freshman texts for calculus-based engineering physics courses with the mathematics worked out clearly and concisely. Helpful diagrams accompany the discussion.

By the end of the unit students will know: electricity and magnetism are related effects that have many useful applications in everyday life. Through a series of hands-on investigations students will experience the effects of magnetism and learn about static and current electricity. Students will design, build, and use: series and parallel circuits, a simple compass, and an electromagnet. Students will learn the role of electromagnets in the construction of electric motors and experience how electrical energy can be converted to heat, light, and motion.
The Grade 4 Physical Science Unit is presented to students through a series of investigations, experiments, active learning experiences, questions, and assessments. Assessments include: pre-, post-, and 3 formative assessments. Conceptual Flow Narrative: The Grade 4 Conceptual Flow Narrative for Physical Science: Matter builds on the concepts presented on conceptual flow graphic by describing the concept s addressed in each lesson and the links that connect each lesson to the next.
Lessons are linked to the previous lesson and the lesson that follows via a conceptual storyline. This ensures the development of student understanding as students progress from one concept to the next. Students also learn that like poles repel each other and opposite poles attract each other. In the previous lesson, students learned about magnetism. Students also learn that magnets are found throughout the world and have many uses.
A Powerpoint presentation is included in the lesson to illustrate the history of magnetism. At the end of the lesson students construct a timeline of discoveries and uses of magnetism. In Lesson 2 students learned about how humans discovered and use magnetism. In Lesson 3 students have been introduced to compasses. Students learn that a compass is an instrument that uses a freely moving magnetic needle to indicate direction.
After Lesson 4, students complete Formative Assessment 1. This assessment is aligned to the learning objectives of Lessons and provides feedback to the teacher, students, and parents about what students have learned in the beginning of the unit.
The teacher is able to use information from this formative assessment to determine if additional instruction is necessary for student understanding of the concepts presented in Lessons before proceeding to the next section of the unit.
In Lesson 4 students made a compass and learned that a compass has a freely moving magnetic needle. Static electricity is the build up of electrons or electric charge. Like electrical charges repel each other, while opposite electrical charges attract.
Lightning is given as an example of the discharge of static electricity. In Lesson 5 students learned that static electricity is the build up of electrical charge. Students investigate how to light a bulb in a simple circuit and discover that complete circuit can be constructed in more than one way using the same materials.
In Lesson 6 students learned how to build simple circuits. Now students will learn about insulators and conductors. In Lesson 7 students how to test various materials for conductivity. If one light bulb goes out in a series circuit, all bulbs will go out because the only path for electricity to travel has been interrupted. Switches open and close circuits. Students also learn about schematics used for electric circuits.
After Lesson 8, students complete Formative Assessment 2. This assessment is aligned to the learning objectives of Lessons and provides feedback to the teacher, students, and parents about student understanding of phase change. The teacher is able to use information from this formative assessment to determine if additional instruction is necessary for student understanding of the concepts presented in Lessons If one light bulb goes out in a parallel circuit, the remaining light bulbs will stay lit because there are multiple paths for the electricity to follow.
An electromagnet is a piece of iron that becomes a temporary magnet when electricity flows through an insulated wire wrapped around the piece of iron.
More coils of wire wrapped around the iron results in a stronger electromagnet. Students conduct an experiment to find out how to increase the strength of an electromagnet. After Lesson 12, students complete a post-assessment to determine their overall understanding of the concepts presented in the unit. Home What is Science Matters? Download PDF.

Electricity and magnetism are separate yet interconnected phenomena associated with the electromagnetic force. Together, they form the basis for electromagnetism , a key physics discipline. It is responsible for the interactions between atoms and the flow between matter and energy. The other fundamental forces are the weak and strong nuclear force , which govern radioactive decay and the formation of atomic nuclei. Since electricity and magnetism are incredibly important, it's a good idea to begin with a basic understanding of what they are and how they work.
Book Description: This textbook emphasizes connections between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigour inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result.

About The Book Fundamentals Of Electricity And Magnetism Book Summary: Primarily intended as a textbook for undergraduate students of Physics, this book provides a comprehensive coverage of electricity and magnetism. Any magnetic particle or object has a "north" and "south" pole, with the directions based on the orientation of the Earth's magnetic field. Magnets and Magnetism.

Electromagnetism is a branch of physics involving the study of the electromagnetic force , a type of physical interaction that occurs between electrically charged particles. The electromagnetic force is carried by electromagnetic fields composed of electric fields and magnetic fields , and it is responsible for electromagnetic radiation such as light. It is one of the four fundamental interactions commonly called forces in nature , together with the strong interaction , the weak interaction , and gravitation. Electromagnetic phenomena are defined in terms of the electromagnetic force, sometimes called the Lorentz force , which includes both electricity and magnetism as different manifestations of the same phenomenon.
By the end of the unit students will know: electricity and magnetism are related effects that have many useful applications in everyday life. Through a series of hands-on investigations students will experience the effects of magnetism and learn about static and current electricity.
Внизу фреон протекал сквозь дымящийся ТРАНСТЕКСТ, как обогащенная кислородом кровь. Стратмор знал, что охладителю потребуется несколько минут, чтобы достичь нижней части корпуса и не дать воспламениться расположенным там процессорам. Он был уверен, что все сделал вовремя, и усмехнулся. Он не сомневался в своей победе, не зная, что опоздал.
Назад, или я сломаю… Рукоятка револьвера, разрезая воздух, с силой опустилась ему на затылок.
- На это уйдет полчаса. К тому времени все уже рухнет. Джабба открыл рот, готовый что-то сказать, но тут его буквально парализовал душераздирающий крик. Все повернули головы к Сьюзан Флетчер, которая выпрямилась и поднялась со стула.
