Discover How Heat Changes Matter With Teach Starter!

Understanding how heat changes matter isn’t just a standard you have to teach—it’s a fundamental part of our everyday lives! By exploring these concepts, students can see the science behind the world around them, from cooking to weather patterns. This year, the Teach Starter team has been hard at work creating new, relevant resources that help your young scientists see the application of their science lessons to the real world. Starting with concepts of matter, we’re excited to help you help them with a brand new scientific prediction and observation activity from Teach Starter.

Real-World Science – Physical Changes Due to Heating (Reversible & Irreversible Changes) Worksheet Set

This resource consists of a pair of printable science observation activities in which students will predict and record their learning about what occurs when heat is applied to different objects in varying phases of matter. It encourages students to see the real-world application of reversible and irreversible changes in substances/scenarios such as:

• boiling an egg
• melting a chocolate bar
• heating corn kernels
• melting ice cubes
• and more!

To complete the task, students will begin by describing the item before any heat is applied. They will also predict whether or not the application of heat will cause a reversible or irreversible change. From there, students will observe or consider what happens to the substance once heated and then describe the new/changed substance. Finally, they will determine if the change seen was reversible or irreversible.

We have included two worksheets in this download, featuring a variety of materials that students are familiar with. An answer key has also been included for easy grading.
