4B Science Simple Machine Alarm Systems

This week the 4B's were proud to present their "Alarm Systems" that they created instead of a final unit exam. The student's were asked to build a unique alarm that could catch a cookie theif. They needed to use two simple machines to create the device, and had to show the class how it worked. The class did an amazing job! I was so proud of the work they put into their alarms.
