About this resource

Description

How can students tell that a brand new substance has formed? This chemical changes matter worksheet helps 5th grade students look for the evidence that a chemical change has happened. A chemical change makes a new substance, and it usually leaves clues behind, such as a color change, gas bubbles, a new smell, light, or a new solid. Learning to spot these signs helps children think and explain like real scientists.

The worksheet begins with five everyday events, from a fizzy tablet dissolving in water to an iron gate that slowly rusts in the rain. Students read each event and use a word bank to name the sign of a chemical change that it shows. Next, they answer two short questions in complete sentences, deciding whether sliced apples that turn brown and an ice cube that melts are chemical changes, and backing up each answer with evidence. A colorful picture of browning apple slices supports the first question.

What’s Included

  • One printable chemical change worksheet (Part A: name the sign of a chemical change for five events)
  • Part B: two constructed-response questions that ask for evidence
  • A complete answer key on the second page

3 Reasons This Worksheet Helps Kids

First, it connects science vocabulary to real events that children have seen at home, such as sour milk and rusty metal. Second, it builds the habit of using evidence, which is central to 5th grade science standards on matter. Third, the written questions ask students to compare a chemical change with a physical change, so they learn why melting ice does not make a new substance.

Ideas for Teachers and Parents

Use this chemical changes matter worksheet after a simple demonstration, such as mixing baking soda and vinegar, so students can connect what they observed to the signs in the word bank. It also works well as a science center activity, homework, a quick review before a unit test, or an independent practice page for homeschool families.
