The Failing Buzzer Worked With 9 Volt

Erion and I made a buzzer that didn't work last week. However, I took the buzzer home and it worked with a 9 volt battery. Yay!

So, the question is, Why did the battery size matter so much. Also, Zack and Nikita managed to get their alarm to work with a less powerful battery last week.

This week, Erion and I also make the Pop Fly Challenge (you can find directions to do this experiment here). You can see the video of work below. You can also see Judy and Adam's video on the PBS Kids DESIGN SQUAD website.
