Science Buddies: "Ask an Expert"

Students picked this topic for the science fair and I am struggling with a question, ID and VD. Can someone please give me some ideas?

Hi - this project is better categorized as an engineering design project instead of a scientific method project. The process for each is different - we have a resource comparing them here: https://www.sciencebuddies.org/science- ... fic-method. Make sure you scroll down far enough to see the video too: https://youtu.be/uIV031bnmFA. Hope that helps! Please write back if you have more questions.
