How Do We Send a Message Using Sound?
In this unit of study, students explore different ways of sending a message and organize them by how the message is sent (light or sound) and by distance. They use a drum to send a simple message using a pattern of sounds. Students collect evidence through hands-on activities and text to build a claim that sound is caused by something vibrating. In the end-of-unit design challenge, students apply what they have learned about sound and engineering to make a simple musical instrument that can send a message a short distance.
In this unit of study, students learn to describe the properties of solids, liquids, and gases and categorize them by their identifiable properties. This unit strengthens students’ ability to observe and describe the properties of solids, liquids, and gases. It also gives students many opportunities to predict results, plan and perform simple tests, and analyze, interpret, and discuss their results. Students have several opportunities to practice their new skills in lessons in which they devise ways of separating a mystery mixture, and plan and carry out investigations that involve other changes.
Air and Weather
This unit of study provides experiences that heighten students’ awareness, curiosity, and understanding of Earth’s dynamic atmosphere and provides opportunities for young students to engage in scientific and engineering practices. Students explore the natural world by using simple instruments to observe and monitor change.
