# Big Idea 8: Properties of Matter

A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass.

B. Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth.

The concepts of mass and weight are complicated and potentially confusing to elementary students. By grades 6-8, students are expected to understand the distinction between mass and weight, and use them appropriately.

Clarification for grades K-2: The use of the more familiar term ‘weight’ instead of the term “mass” is recommended for grades K-2.

Clarification for grades 3-5: In grade 3, introduce the term mass as compared to the term weight. In grade 4, investigate the concept of weight versus mass of objects. In grade 5, discuss why mass (not weight) is used to compare properties of solids, liquids and gases.

This Model Eliciting Activity (MEA) is written at a 5th grade level. The Shady Day MEA provides students with an engineering problem in which they must work as a team to design a procedure to select the best beach umbrella for certain situations.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

Chemical Change Investigations | Inquiry in Action:

In this series of 10 investigations, students gain experience with the evidence of chemical change - production of a gas, change in temperature, color change, and formation of a precipitate. Students begin by observing that similar-looking powders can be differentiated by the way they react chemically with certain test liquids. Students then use their chemical tests and observations to identify an unknown powder and, in a follow-up activity, to identify the active ingredients in baking powder. Students continue to explore chemical change by using a thermometer to observe that temperature either increases or decreases during chemical reactions. Then they control these reactions by adjusting the amount of reactants. In another set of activities, students use the color changes of red cabbage indicator to classify substances as acids or bases, neutralize solutions, and compare the relative acidity of two different solutions. Students conclude the investigation by comparing a precipitate to one of the reactants that formed it. Students see that a new substance was created during the chemical reaction. Information and questions about photosynthesis and cellular respiration are included as examples of chemical changes on pages 316-318 of this resource.

The other activities in this investigation are examples of tests students can conduct on the crystals. After a series of these tests, students will gather enough evidence to identify the unknown crystal.
