A great activity to introduce scientific methods, graphing, and measurement. This could be used at the start of the school year to introduce students to these methods or it could be used at the end of a unit or course as a lab practical.
In this activity, students will test the melt rate of ice using various types of ice. Directions are provided for modification if you do not have the lab equipment necessary. After collecting data, students will graph their results, compare their results to their classmates, and participate in a class discussion about the results (teacher questions provided!) .
