Half Hollow Hills CSD Science Department
GRADE 5 UNIT: Chemistry Essential Question
How do chemical reactions and changes in states of matter affect the physical environment?
New York State Standards/Key Ideas:
Standard 4: Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.
KEY IDEA 3: Matter is made up of particles whose properties determine the observable characteristics of matter and its reactivity.
New York State Performance Indicators: • Students will develop mental models to explain common chemical reactions and changes in states of matter.
Major Understandings:
Students will understand that:
• All matter is made up of atoms. Atoms are far too small to see. • Atoms and molecules are perpetually in motion. The greater the temperature, the greater the motion. • Atoms may join together in well-defined molecules or may be arranged in regular geometric patterns. • Interactions among atoms and/or molecules result in chemical reactions. • The atoms of any one element are different from the atoms of other elements. • There are more than one hundred elements. Elements combine in a multitude of ways to produce compounds that account for all living and nonliving substances. Few elements are found in their pure form. • The periodic table is one useful model for classifying elements.
GRADE 5
Chemistry
Essential Questions: • • • • •
How are atoms arranged? How does temperature affect atoms? Why do elements combine? How is the periodic table organized? How do atoms interact to cause chemical reactions?
Students will know: • Matter is composed of elements. • Elements are made of small particles called atoms. • All living and nonliving materials are composed of elements or the combination of elements. • The periodic table is used to classify elements. SVocabulary: metal molecules substance protons nonmetal interaction atoms neutrons compound atomic number electrons particle atomic weight nucleus noble gas periodic table elements
Skills:
Students will be able to: • Use the periodic table. • Identify and element as a metal, nonmetal, or noble gas. • Determine the identity of an unknown element, using physical ane chemical properties. • Follow safety procedures in the classroom and laboratory. • Recognize ane analyze patterns and trends.

MINILESSON 4: Classify elements using the periodic table LEARNING OBJECTIVES Students will know That the periodic table is used to classify elements. Students will understand That the periodic table is a useful model for classifying elements, which can be used to predict properties of elements. Students will be able to Use the periodic table, and identify an element as a metal, nonmetal, or a noble gas. MINILESSON PROCEDURE Required Materials Computer with internet access, periodic table. Required Background Information Knowledge of the structure and composition of an atom. Knowledge of what elements are and how they are organized in the periodic table. Process & Procedure (How will you teach this lesson?) Have the students choose an element and collect the following information about their element: • Element name • Element symbol • Atomic number of element • Atomic mass number of element • Energy level drawing of element • Origin of element’s name • Name of person/s who discovered the element • Date of discovery • Three common uses of element • Three little known yet interesting facts about element Create either a 6 page brochure, or a poster representing their element. Students choosing to do a brochure, should have the following information: A. Cover- Element name, symbol, atomic number, and atomic mass number. Author name should go on cover. B. Page 2- An energy level drawing of the element. This should be titled “Energy Level Diagram” labeled or color-coded. C. Page 3- Title this page “Did You Know?” The following pieces of information are in complete sentences and appear as a bulleted list: 1. Origin of elements name 2. Name of person/s who discovered the element 3. Date of discovery
D. Page 4- This page should be titled “Common Uses.” The common uses should be written in sentences and appear as numbered items. E. Page 5- This page should be titled “Interesting Facts.” The collected facts should be written in sentences and appear as numbered items. F. Page 6- This page should be titled “About the Authors.” Each author will write a paragraph about his/herself. If a digital camera or scanner is available, students will include a picture on the page.
