After you've done your research and concluded your experiments,
it is time to prepare for the science fair. Ask specific
questions about preparing for a science fair, including:
judging, how to set up your display board, preparing a
presentation, preparing for questions... (Please post questions
about selecting a project or conducting your experiment by
posting in the appropriate "area of science" forum.) Moderators:
MelissaB, kgudger, Ray Trent, Moderators My son just completed
his project "Can Water Float on Water". Now he's writing some
background information on it. We are both confused because were
not sure if it's a Chemical Change or a Physical Change. We
mixed salt, water and food coloring together. I thought it was a
Physical Change because no new bonds were formed (the salt
remained the same as well as the food coloring and water). My
niece thinks it a Chemical Change because of the salt & food
color. Please help. His project is due ASAP. Thanks So Much.
Also, how do you know when you have responded.
