Emily,

Icicles are "stakes" of ice formed when water is slowly dripped from a surface. As the water drips, it freezes. As more water drips, more of it freezes as it rolls down the icicle that has begun to form. Where do you usually see icicles? When do they form? Where I live in South Louisiana, we only see icicles once or twice a year. Where you live I'm sure you see them all winter. Ask yourself some questions about How, When, Where, and What. How does the water drip down? When do they form? What are the weather conditions like? What do they look like? Are they fat at the bottom or top? What is the bottom and what is the top? Where do i usually see them? Are they on buildings, ponds, high up or on the ground? Do they form during snowy conditions or in rain and then a freeze?

This is what science is. Asking the question, and then asking more, getting answers, making observations and then comming to conclusions. You've taken the first step, now finish the inquiry.

Thanks,

Robert Judge
