1 Ohio Standard Batterie 9th grade 1. Recognize that all atom of the ame element contain the ame number of proton, and element with the ame number of proton may or may not have the ame ma. Thoe with different mae (different number of neutron) are called iotope Illutrate that atom with the ame number of poitively charged proton and negatively charged electron are electrically neutral. 3. Decribe radioactive ubtance a untable nuclei that undergo random pontaneou nuclear decay emitting particle and/or high energy wavelike. 4. Show that when element are lited in order according to the number of proton (called the atomic number), the repeating pattern of phyical and chemical propertie identify familie of element. Recognize that the periodic table wa formed a a reult of the repeating pattern of electron configuration. 5. Decribe how ion are formed when an atom or a group of atom acquire an unbalanced charge by gaining or loing one or more electron. 6. Explain that the electric force between the nucleu and the electron hold an atom together. Relate that on a larger cale, electric force hold olid and liquid material together (e.g., alt crytal and water). 2-2, , , ,

2 Nature of matter 7. Show how atom may be bonded together by loing, gaining or haring electron and that in a chemical reaction, the number, type of atom and total ma mut be the ame before and after the reaction (e.g., writing correct chemical formula and writing balanced chemical equation). 8. Demontrate that the ph cale (0-14) i ued to meaure acidity and claify ubtance or olution a acidic, baic, or neutral. 9. Invetigate the propertie of pure ubtance and mixture (e.g., denity, conductivity, hardne, propertie of alloy, uperconductor and emiconductor). 10. Compare the conductivity of different material and explain the role of electron in the ability to conduct electricity. 11. Explain how thermal energy exit in the random motion and vibration of atom and molecule. Recognize that the higher the temperature, the greater the average atomic or molecular motion, and during change of tate the temperature remain contant. 14. Summarize how nuclear reaction convert a mall amount of matter into a large amount of energy. (Fiion involve the plitting of a large nucleu into maller nuclei; fuion i the joining of two mall nuclei into a larger nucleu at extremely high energie.) 2-2, 2-3, 2-4, 2-6, , 3-2, , Batterie 12-1, 12-2

3 15. Trace the tranformation of energy within a ytem (e.g., chemical to electrical to mechanical) and recognize that energy i conerved. Show that thee tranformation involve the releae of ome thermal energy. Batterie Nature of energy 16. Illutrate that chemical reaction are either endothermic or exothermic (e.g., cold, hot and the burning of foil fuel). 17. Demontrate that thermal energy can be tranferred by conduction, convection or (e.g., through material by the colliion of particle, moving air mae or acro empty pace by form of electromagnetic ). 18. Demontrate that electromagnetic i a form of energy. Recognize that light act a a wave. Show that viible light i a part of the electromagnetic pectrum (e.g., radio wave, microwave, infrared, viible light, ultraviolet, X-ray, and gamma ray). 26. Ue hitorical example to explain how new idea are limited by the context in which they are conceived; are often initially rejected by the cientific etablihment; ometime pring from unexpected finding; and uually grow lowly through contribution from many different invetigator (e.g., atomic theory, quantum theory and Newtonian mechanic) , , 7-3,

4 Nature of matter Hitorical perpective 11th grade 12th grade 27. Decribe advance and iue in phyical cience that have important, long-lating effect on cience and ociety (e.g., atomic theory, quantum theory, Newtonian mechanic, nuclear energy, nanotechnology, platic, ceramic and communication technology). Explain that element with the ame number of proton may or may not have the ame ma and thoe with different mae (different number of neutron) are called iotope. Some of thee are radioactive. 2. Explain that human have ued unique bonding of carbon atom to make a variety of molecule (e.g., platic). 1. Explain how atom join with one another in variou combination in ditinct molecule or in repeating crytal pattern. 2. Decribe how a phyical, chemical or ecological ytem in equilibrium may return to the ame tate of equilibrium if the diturbance it experience are mall. Large diturbance may caue it to ecape that equilibrium and eventually ettle into ome other tate of equilibrium , 5-2, , 8-2, 8-3, 8-4 Batterie 11-1, 11-2, 11-3

5 Nature of matter 3. Explain how all matter tend toward more diorganized tate and decribe real world example (e.g., eroion of rock and expanion of the univere). 4. Recognize that at low temperature ome material become uperconducting and offer little or no reitance to the flow of electron. Batterie Nature of energy 10. Explain the characteritic of iotope. The nuclei of radioactive iotope are untable and pontaneouly decay emitting particle and/or wavelike. It cannot be predicted exactly when, if ever, an untable nucleu will decay, but a large group of identical nuclei decay at a predictable rate. 11. Ue the predictability of decay rate and the concept of half-life to explain how radioactive ubtance can be ued in etimating the age of material. 12. Decribe how different atomic energy level are aociated with the electron configuration of atom and electron configuration (and/or conformation) of molecule. 13. Explain how atom and molecule can gain or loe energy in particular dicrete amount (quanta or packet); therefore they can only aborb or emit light at the wavelength correponding to thee amount

6 Batterie Hitorical perpective 14. Ue hitorical example to explain how new idea are limited by the context in which they are conceived; are often initially rejected by the cientific etablihment; ometime pring from unexpected finding; and uually grow lowly through contribution from many different invetigator (e.g., nuclear energy, quantum theory and theory of relativity). 15. Decribe concept/idea in phyical cience that have important, long-lating effect on cience and ociety (e.g., quantum theory, theory of relativity, age of the univere). 1-1 and throughout Science & Technology, Scientific Inquiry & Science a a way of Knowing tandard: Thee tandard are introduced in 1-1 and ued throughout the text. Each chapter include inquiry lab, dicovery lab (tudent derive meaning from data before being formally introduced to concept) and a connection to technology through the chapter theme. Student are aked to communicate their finding, dicu dicrepencie with their clamate, come to concenu baed on evidence, etc., modeling the cientific community.
