To Curl or Not to Curl
We like doing each others hair. We tried using rollers to make our hair curly. This got us wondering about rollers. We wanted to know the science behind curly hair.
Question: Which material curls best when using rollers ?
Hypothesis:We think that the pipe cleaner would curl the most because the metal in the pipe cleaner is more stiff than the other materials and will hold the curl better.
Materials:
Procedure:1.Gather and lay out materials. 2.Measure each object to 10 inches and cut. 3.Put water in spray bottle and then spray each object. 4.Roll each material onto the roller. 5.Use a hair dryer and dry the materials. 6.Take the materials off the roller. 7.Remeasure your materials to see the outcome of the experiment. 8.Record data. Special Needs: For our experiment we need to be by an outlet for the hair dryer. |
Watch us in action:
Safety ProceduresWhen using a hair dryer do not have it touching the object you are drying.
