Questions & Answers

Q: How do you make a motion sensor using a balloon?

To make a motion sensor, you need a balloon, a tack, and some tape. Attach the inflated balloon to the door or entrance, and secure a tack at the opposite side. When someone enters and opens the door, the balloon will move and the tack will alert you to the motion.

Q: Can sensors detect motion without emitting sound?

Yes, sensors don't always have to emit sound. As long as a sensor detects the motion or change, it serves its purpose. In the example of the drawer sensor, it detects the opening of a drawer without producing any sound.

Q: How can aluminum foil be used to make a sensor?

To make a sensor using aluminum foil, you need to tape a piece of aluminum foil to a door or drawer. When the door or drawer is opened, the foil will be separated from its original position, indicating the motion or change.

Q: Why is it important to understand sensors and STEM concepts?

Understanding sensors and STEM concepts helps build STEM identities in students. It allows them to explore and engage in scientific and technological innovations, contributing to future advancements and improving our society.

Summary & Key Takeaways

• Ebony and David demonstrate how to make three beginner-level sensors using household supplies.

• The first sensor detects motion in a room using a balloon and a tack.

• The second sensor detects the opening of a drawer using a crayon and a piece of paper.

• The third sensor detects the opening of a door or drawer using aluminum foil.
