Introduction+to+Matter

=Eighth grade curriculum: Introduction to Matter=

September 20, 2010 to September 24, 2010 based on The 21st Century Center for Research & Development in Cognition & Science Instruction

• Section 1: The Properties of Matter (Sept 20- Sept 24)

– Section 1: What is Matter – –In this chapter you will learn what matter is and how it can described. –You will also learn that different types of matter have unique physical and chemical properties. –The physical and chemical changes that matter can undergo are also presented.

Day 1 and 2: Compare Solids & Liquids Contrasting Case Activity

In this activity, students record their initial ideas about the properties of solids and liquids. They then compare two samples of each -- modeling clay, salt, water, and white glue -- and revise their lists to include properties of the samples. Next, they add a few drops of food coloring to each sample and revise their lists to include the outcome they observe. Materials needed:  •small plastic cups -- to hold samples •samples -- about 15 ml (1 tbsp) each of modeling clay, salt, water,  and white glue (e.g., Elmer’s Glue)  •hand lenses •food coloring

Day 3: Compare Liquids & Gases

Students will record their initial ideas about the properties of liquids and gases. They will then complete an experiment with syringes and revise their lists to include properties revealed by the experiment. Next, they will observe a demonstration involving ammonia and litmus paper and revise their lists to include the outcome they observe. <span style="direction: ltr; display: block; margin-bottom: 0pt; margin-top: 3.96pt; text-align: left; unicode-bidi: embed; vertical-align: baseline;"><span style="color: black; font-family: Arial; font-size: 11.0pt; language: en-US; mso-ascii-font-family: Arial;">Materials needed: <span style="direction: ltr; display: block; margin-bottom: 0pt; margin-top: 3.96pt; text-align: left; unicode-bidi: embed; vertical-align: baseline;"><span style="color: black; font-family: Arial; font-size: 11.0pt; language: en-US; mso-ascii-font-family: Arial;"> •10 oz. cups with water <span style="direction: ltr; display: block; margin-bottom: 0pt; margin-top: 3.96pt; text-align: left; unicode-bidi: embed; vertical-align: baseline;"><span style="color: black; font-family: Arial; font-size: 11.0pt; language: en-US; mso-ascii-font-family: Arial;"> •syringes <span style="direction: ltr; display: block; margin-bottom: 0pt; margin-top: 3.96pt; text-align: left; unicode-bidi: embed; vertical-align: baseline;"><span style="color: black; font-family: Arial; font-size: 11.0pt; language: en-US; mso-ascii-font-family: Arial;"> •3 oz. cup (to hold ammonia) <span style="direction: ltr; display: block; margin-bottom: 0pt; margin-top: 3.96pt; text-align: left; unicode-bidi: embed; vertical-align: baseline;"><span style="color: black; font-family: Arial; font-size: 11.0pt; language: en-US; mso-ascii-font-family: Arial;"> •large glass jar or beaker (to invert over ammonia) <span style="direction: ltr; display: block; margin-bottom: 0pt; margin-top: 3.96pt; text-align: left; unicode-bidi: embed; vertical-align: baseline;"><span style="color: black; font-family: Arial; font-size: 11.0pt; language: en-US; mso-ascii-font-family: Arial;"> •ammonia <span style="direction: ltr; display: block; margin-bottom: 0pt; margin-top: 3.96pt; text-align: left; unicode-bidi: embed; vertical-align: baseline;"><span style="color: black; font-family: Arial; font-size: 11.0pt; language: en-US; mso-ascii-font-family: Arial;"> •red litmus paper
