DO YOU KNOW THE TEMPERATURE A CRAYON WILL MELT?
Students in Mrs. Sams 1st grade class at Whitley Central Primary can tell you. As part of a CER (Claim, Evidence, Reasoning) activity, students predicted at what temperature a crayon would melt and how long they thought it would take using a common household hair dryer. Students first determined things they knew: A crayon is a solid, and a solid can change to a liquid when there is heat. Using their prior knowledge and crayons glued to a canvas in sections labeled “low,” “medium,” and “high,” students predicted how long it would take for the melting to begin. Students discovered that the higher the heat setting was on the faster the crayons melted. Student also discussed other things that might cause a crayon to melt and how long it might take.
