This section describes the 5 states of matter. (2) Record the 5th state of matter that was observed in 1995 here: (3) Draw and label the remaining 4 states of matter using the diagram shown below. Locate the link, “Phase Changes” in the list of links in the upper right corner of this webpage. Follow this link to the page, Changing States of Matter. Use the information and diagrams from the first 2 paragraphs on this page to respond to the following: (4) Record the phrase used to describe the point at which a liquid becomes a solid. (5) Record the type of pressure that makes it easier to freeze matter. (6) Record the phrase used to describe the point at which a solid becomes a liquid. 1 Locate the link, “Chemical-Physical” listed below the “Phase Changes” link in the upper right corner of this page. Follow this link to the page, Chemical vs. Physical Changes. Use the information and diagrams from this page to respond to the following: (7) Describe the type of change that is occurring in the pipes shown on the left side of this page. Neon lights are also shown on this page and are described as a gas that is electrically charged to produce a plasma state of matter. Locate the “Plasmas” link in the list of links in the upper right corner of this page. Follow this link to learn more about plasmas. Based on the information in the first and third paragraphs, respond to the following: (8) Record at least 3 other plasma examples discussed in this section. Explore 3 links from this website that were not included in this web quest and record your knowledge discoveries. (9) Record your 1st webpage subtitle followed by your knowledge discovery. (10) Record your 2nd webpage subtitle followed by your knowledge discovery. (11) Record your 3rd webpage subtitle followed by your knowledge discovery. 2 PERIODIC TABLE WEBQUEST (www.CHEM4KIDS.com) Type the web address shown above in the Internet address bar and press “Enter.” Locate and click the “Atoms” link. Scroll to the last paragraph on this page and review the sequence of terms listed to gain an understanding of how atoms are the building blocks for the universe. As you navigate through this website, locate and record definitions for the words listed in the table below. Vocabulary Atom Protons Electrons Neutrons Nucleus Orbital Element Group Period Web Location Atom Basics: Structure Link Atom Basics: Structure Link Atom Basics: Electrons Link Atom Basics: Structure Link Atom Basics: Structure Link Atom Basics: Orbital Link Atom Basics: Overview Periodic Table: Periodic Table Periodic Table: Periodic Table Atomic Number NA Atomic Mass NA Ionic Bonding Covalent Bonding Isotopes Definition A unique number for each element that indicates the number of protons and electrons found in the atom. The mass of the atom. Subtracting the atomic number from the atomic mass will tell you the number of neutrons in the atom. Atom Basics: Ions Atom Basics: Ions Atom Basics: Isotopes Link 3 Periodic Table of Elements Research Use the following websites and worksheet to locate information about the element you are researching for class. www.chem4kids.com www.chemicalelements.com www.chemicool.com Name of the element: Atomic Symbol: Atomic Number: Atomic Mass: Neutron Number: Electron Configuration: Group Number: Family Name: State of Matter: Provide a paragraph telling who discovered the element, when and where it was discovered, where it is found, and what it is used for, as well as any other interesting information. The paragraph must be at least five sentences long. Type the final draft of your paragraph using Microsoft Word. Draw, or insert, a Bohr model diagram of the atomic structure of the element, including all of the electron orbitals. Your drawing may be completed by hand or using graphics in computer software. Refer to the sample provided by the teacher on the next page, if needed. Be sure to cite your resources. 4 Poster Sample C (Information about your element can be listed here.) (Insert the Bohr model of the atomic structure of your element here.) (Insert the pictures of element and how it is used in the real world here.) 5
