8.PS4.1 (TN)

In this unit, students explore technological systems, focusing on the phenomena of how information is transmitted in a communication system. This page is a high-level extract of the first lesson in this unit.

In this unit, students explore how communication systems transmit information from one person or place to another. In this lesson, students use what they know about the science phenomena of electromagnets and magnetic fields to design a speaker, a common decoding device in many audio technologies. This page highlights key components of this lesson.

In this unit, students explore the science phenomena of waves and information transfer. For the first lesson of this unit, students identify the properties of different kinds of waves. This page is a high-level extract of this lesson. 

In this unit, students focus on the properties of different kinds of waves and the relationship between waves and energy. In this lesson, students design a simple seismograph using what they know about the properties of seismic waves produced by earthquakes. This page is a high-level extract of this lesson.

In this unit, students explore the properties of different kinds of waves and the relationship between waves and energy. In this lesson, students investigate how waves can be used to communicate and transmit information. This page highlights key components of this lesson.

In this lesson, students explore the science phenomena of waves, investigating properties of waves, how waves carry energy, and how they can be used to transmit information. This page highlights key components of this lesson.
