|KALMIOPSIS EXPLODES: STUDENTS SHOW OFF SCIENCE PROJECTS|

A volcano erupted, icicles formed and salt water turned into fresh water in Marion Carrillos third grade class last week.
Carrillos students, one by one, approached the front of the class to explain the purpose and function of the projects they had created during the last quarter.
The state mandates that the children give a speech to the class, said Carrillo. So I had the kids give their speech along with their science project, to include the scientific aspect.
We used the scientific method for each project, starting with a problem, then continuing with a hypothesis, procedure and conclusion.
Anthony Babb constructed a volcano out of chicken wire, flour, water and newspaper. He then created his own lava by pouring baking soda and vinegar into the mouth of the volcano. A foaming white liquid oozed over the side.
Its a good project to do if its raining outside, said Babb. Or you can get together with a friend or your little brother.
Tyler Frazee constructed a battery with wires and metal clips attached to demonstrate what items conducted electricity.
I looked in a book about all different science projects you can do, and found this one, said Frazee. My grandma helped me out; we bought the materials at Fred Meyer. I learned that wood, plastic and crayons do not conduct electricity.
Emily Eller explained how fossils were made, and brought her own home-made fossils from plaster of Paris poured into clay molds.
Heidi Moore made snowflakes out of pipe cleaners, Vanessa Meier created icicles, Amber Peterson demonstrated how mold grews, and Eric Olson turned a copper penny into a silver-colored penny.
A piece of newspaper was care fully glued to a poster board for Emilee Bottoms recycling project. Bottoms explained how a piece of newspaper could be recycled into a blank piece of paper.
I put a piece of newspaper into a blender and poured water over it so that it is totally covered, she said.
I let it set for 10 minutes, then blended it again. Then I took a hanger and formed it into a circle and put nylon over it. I filtered all the blended newspaper through the nylon until all the water drained. I placed a paper towel on top of a cutting board and pounded the paper on it. Then you let the paper dry, but it doesnt come out perfectly white; there was still some ink in it.
Dayna Irwin explained how fresh water could be made from salt water. My older brother helped me out with the experiment, because he had done it before, she said.
Now, if the Afghanistans make our water dirty, I know how to make it clean.
High school science teacher Tim Buehler will judge the projects at the end of this week and hand out ribbons.
The projects will then be on display at Chetco Community Public Library next week in the childrens section. They are scheduled to be on display for three weeks.
