Using a stirring rod, sophomore Joyce Harbeston mixes in the salt and water placed in the test tube. There were a total of twelve stations that the students needed to complete. “I was trying to be very careful [the whole time],” Harbeston said. “For this lab, we put a few drops of silver nitrate into the test tube, which could stain your skin. The mixture ended up turning into this foam, which floated to the top of the water.”

By increasing the string length, the tension is increased as well as the risk of the cup’s water falling out. “We have all these components and it’s really important [to get them right] because it can risk people lives,” Estrellas said. “They can risk your own life. Its like preventing risk factors, and that’s why applying it [physics] to real life is a real eye opener because I really saw what was going to happen if I make a mistake or don’t understand principles and calculations behind it [our project].”](https://southwestshadow.com/wp-content/uploads/2025/01/IMG_9805-1200x800.jpg)

Some groups took a more humorous approach to the project. “We put [our partner’s height] range between five feet and 15 feet,” Hsi said. “We wanted them to be really tall, but we couldn’t find a specific height we were all comfortable with, so they’re just a stepladder.”](https://southwestshadow.com/wp-content/uploads/2025/01/IMG_9919-1200x673.jpg)
