Investigate that materials can be altered to change some of their properties, but not all materials respond the same way to any one alteration.
Standard #: SC.2.P.9.1
Standard Information
General Information
Subject Area: Science
Grade: 2
Body of Knowledge: Physical Science
Big Idea: Changes in Matter - A. Matter can undergo a variety of changes.

B. Matter can be changed physically or chemically.

Clarification for grades K-5: The target understanding for students in the elementary grades should focus on Big Ideas A and B.

Clarification for Grades 6-8: The target understanding for students in the middle grades should begin to transition the focus to: C. When matter changes chemically, a rearrangement of bonds between the atoms occurs. This results in new substances with new properties.

Lesson Plans
  • Not Easy Being Green # Students will apply their understanding that materials’ properties can change, to explain why objects made of copper typically turn green over time. From the Statue of Liberty to pennies, students will know that when copper is exposed to air it will eventually turn green in this integrated lesson plan.
  • Candy Homes # In this project based learning experience, students explore and sort different candies based on their physical properties and how they can be altered and changed. They will determine which properties of the candy would be most beneficial to build a successful home/structure. Students will create a model of their home using their chosen candy and support their choice by writing an opinion and preparing a presentation.
  • Look How It Changes # Students will have an opportunity to use informational texts to explore the physical and chemical changes that occur throughout the seasons of the year. Additionally, students will use examples from the text and images to define the terms, physical and chemical changes.
  • The Physical Changes of Matter # Students will be using the open inquiry (student-driven) approach to conducting a science investigation. They will be looking at matter and how it can be affected physically by its size, shape, color, and by adding/taking away heat.
Original Student Tutorials
  • Not Easy Being Green # Explore how the properties of materials change, including how the copper metal covering the Statue of Liberty changes from a brownish color to a greenish patina over time, with this interactive tutorial.
  • Changing Properties # Was the statue of liberty always green? Why do some things rust? Exactly how cool were hypercolor shirts? Explore these questions and more as we investigate how different materials react to situations that may change their properties in this interactive science tutorial.
Teaching Ideas
  • The Gummi Bear Experiment # Students will have an opportunity to conduct an investigation about Gummi Bears and how they dissolve.
  • How Degrading-SeaWorld Classroom Activity # In this activity, given examples of trash generated by a family over a 24-hour period, the student will be able to demonstrate how some materials degrade in salt water better than others. They will be able to generate ideas for ways to reduce plastic pollution.
