Practice the scientific method with this great hands-on investigation for 2nd and 3rd grade. Learn about the freezing point of water and the effects of salt on ice. Teachers will find the packet easy to follow, useful, and age appropriate. Students will have lots of fun and be engaged.
In this investigation students will use the scientific method to investigate how salt affects ice. The students will test if the amount of salt will affect the ability of a piece of string to pick up an ice cube. They will write a hypothesis, follow procedures, record observations and data, create a graph, and write a summary. The students will learn how to rank their observations to create a graph. By the end of this investigation the students should understand that salt lowers the freezing point of ice.
The materials needed are:
cup or mason jar
