Ask questions to plan and carry out investigations to identify substances based on patterns of their properties. Emphasize using properties to identify substances.
In this unit, students build on their exploration of how energy and matter interact with a focus on science phenomena related to sound. In this lesson, students investigate how some materials absorb sound while others reflect it. This page is a high-level extract of this lesson.
In this unit, students focus on how sound energy is transferred from one place to another in waves. In this engineering lesson, students apply what they have learned about sound energy to design a sound absorbing wall. This page highlights each component of this lesson.
In this unit, students focus on light energy, investigating the science phenomena of how light moves when it interacts with different kinds of matter. Students use scientific knowledge about light to engineer a device that uses mirrors to redirect light. This page is a high-level extract of this lesson.
