Science Buddies: "Ask an Expert"

We did the weather project "What happens when a warm front meets a cold front". We used the balloon and water expirement and are done with most of the work but are stuck on how to do a graph or chart. Any suggestions on what to do for a graph or chart?

Hi there,

Welcome to Science Buddies! It sounds like you decided to do this abbreviated project idea: https://www.sciencebuddies.org/science- ... p016.shtml

Can you tell me a little more about your procedure? Did you float a cold water balloon in hot water, a hot water balloon in cold water, or both?

What did you measure? Did you measure the direction of movement of the balloon? How did you record the information?

Once I understand your results, I can help you present them in a graphical form.

We did hot water balloon in cold water and the cold water balloon in hot water. The hot balloon floated in cold water and the cold balloon sank in hot water. Both reacted instantly. Still not sure how to graph.

Hi Taylor,

I understand your confusion. It is rather difficult to graphically represent "float" vs. "sink." Your data are more qualitative (something you saw) than quantitative (number-based). Have you considered displaying photos of what happened?
