* Snap Circuits are available with upgrades, so you can add parts and projects as needed. The Mom recommends Snap Circuits 100, which can be upgraded to the 300, 500 and 750 sets if your child stays interested, and includes the Flying Saucer project.

TIPS:
• Label the numbers and letters on the baseplate with Sharpie to make assembly easier. Drawing lines on the grid is also helpful.
• Use colored pencil to circle or label the different layers of parts in your diagram before starting.
• Younger children may need help snapping the parts together.

PROJECT 3: Sound Activated Switch

OBJECTIVE: To show how sound can turn "ON" an electronic
device.


When you close the slide switch (Sl), the music may play for a short
time, and then stop. After the music has stopped, clap your hands
close to the whistle-chip (WC) or tap the base with your finger. The
music should play again for a short time, then stop. Blow on the whistle chip and the music should play.


You could connect the speaker using snap wires instead of the jumper
wires, but then the speaker may create enough sound vibrations to reactivate the whistle chip.

ABOUT SAGAN AND LOKI:

Sagan and Loki provide Me Time for parents and kid-approved homeschool and afterschool ideas for kids. The show is Sagan's Genius Hour project, an elective class where he gets to chase his passion while he learns how to run a business. He decides what happens on the show.
