States of Matter: Freezing and Melting Worksheet

4.8 based on 68 votes

Complete in App

Materials can exist in more than one form; they can be either in a liquid form, or a solid form. These are called states of matter. However, when heated or cooled, matter changes its state. When heated, some solid materials change to liquid, and this process is called melting. When cooled, materials that were in liquid form turn into solid, and this process is known as freezing. Look through the pictures in the worksheet with your students. Ask them what changes of state are shown in the pictures, then trace on the dotted lines to the correct answers.

Required skills:
To resolve this worksheet, students should know what the different states of matter are and how they can change from one state to another (such as melting or freezing). They should also be able to observe and identify these changes in pictures, and be able to follow instructions for tracing the correct answers.

Daughter's favorite
Still a top favorite for our 7 year old. She loves earning her stars as she learns to trace letters and numbers. Coloring and the sounds are engaging and are on target for her age group and being Pre K.

Such a great app!
This was a really fun way to get my kids to practice their math. I usually struggle to get them into it and Kids Academy makes it easy.
