Let's Do Science Let's Do Science is based on the United States Next Generation Science Standards (NGSS). The series consists of full-color textbooks and full-color activity books for Grades K to 6. Let's Do Science engages students with a highly visual presentation of the disciplinary core ideas in the textbooks and places an emphasis on applying scientific knowledge using NGSS practices through numerous scientific investigations. Let's Do Science sees engineering as an essential element of science education and as such is tightly integrated into both the textbooks and activity books. The Let's Do Science activity books include the follow features:

Design a Musical Instrument

Goes beyond inquiry by encouraging students to design, model and build to engineer solutions to defined problems.

Procedure

!

Musical instruments make sounds in different ways. Some make sound when you blow into them. Some make sound when you hit, shake or pluck them. Now it’s your turn to make your own musical instrument.

1. Use the materials to design and build a musical instrument. Think about how your instrument will make sound and how the sound can be changed. 2. Draw a model and build your instrument.

Materials • art and craft supplies

• balloons

3. Explain to a friend how your instrument produces sound. Explain how you can change the sounds it makes.
