Recognize that there are a finite number of elements and that their atoms combine in a multitude of ways to produce compounds that make up all of the living and nonliving things that we encounter.


General Information

Subject Area: Science
Grade: 8
Body of Knowledge: Physical Science
Big Idea: 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 which gives it inertia.

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. Hence, the more familiar term of "weight" is recommended for use to stand for both mass and weight in grades K-5. 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.

Assessment

Name Description
Adopt An Element This can be used as a homework assignment or completed in the computer lab. Students will have to research information on one element and complete an advertisement for that element as if they were trying to market it.

Lesson Plans

Name Description
All the Small Things

Students will observe and analyze visual representations. Students will sort, classify and compare their findings to known characteristics of pure substances (elements and compounds) and mixtures. Students will differentiate matter into pure substances (elements and compounds) and mixtures on a basic molecular level. Students will use hands-on card sorting to create a rule for sorting matter. The definitions of pure substance, mixture, element, and compound will be introduced.

Alien Elements-Are they hiding here?

This lesson is a high interest presentation and activity that presents the concepts of elemental composition, temperature effects, and states of matter geared to 8th graders.

What are you made of? Students will learn about known elements and discover the products that can be made when those elements react.
Search for Extraterrestrial Life

In this Model-Eliciting Activity (MEA), students rank locations that NASA should search within our solar system for life. Students begin by reading about the origins of life on Earth and locations within our solar system with the potential for life. After students create a ranked list, they must report their findings to NASA in the form of a letter that also includes the procedure used in ranking their choices. A second request is sent from NASA to include distance from Earth as a factor in the ranking of locations and students must return a letter with their revised rankings and the new procedure used.

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 processes. 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. To learn more about MEAs visit: https://www.cpalms.org/cpalms/mea.aspx

Explainer: How and Why Fires Burn

This informational text resource is intended to support reading in the content area. This article explains the science behind why and how fire burns. The article describes why fire is not considered matter and what is required for fire to burn, as well as how the atoms rearrange themselves during the combustion process. 

We Are Stardust

This informational text resource is intended to support reading in the content area. This text examines how humans and all things around us are made of elements created in stars. The article references fusion, the powerful collision of enormous stars, and the intense explosion of supernovas. All of this is tied to the creation of heavier elements that hurtle through space, to be reassembled as distant solar systems.
