TEKS OBJECTIVES:

(5)  Matter and energy. The student knows the differences between elements and compounds. The student is expected to:

(A)  know that an element is a pure substance represented by chemical symbols;

(B)  recognize that a limited number of the many known elements comprise the largest portion of solid Earth, living matter, oceans, and the atmosphere;

(C)  differentiate between elements and compounds on the most basic level; and

(D)  identify the formation of a new substance by using the evidence of a possible chemical change such as production of a gas, change in temperature, production of a precipitate, or color change.

September 8-19, 2011

Discuss elements and give examples of their symbols. Lab on the elements involved in a chemical change.  Discuss how elements form compounds. Labs on looking for clues that give evidence of a chemical change.

September 20-23, 2011

Study Sheets and review over elements and compounds.  Students who do their study sheets well also do well on the test.  Study sheets will be due Sept. 22 and 23.

September 26-27, 2011

Test over elements and compounds.  Review all study sheets carefully.  Extra credit points will be given to those students who get their study sheets signed.

TEKS OBJECTIVES:

(1) Scientific investigation and reasoning. The student, for at least 40% of instructional time, conducts laboratory and field investigations following safety procedures and environmentally appropriate and ethical practices. The student is expected to:

(A) demonstrate safe practices during laboratory and field investigations as outlined in the Texas Safety Standards; and

(B) practice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials.

(4) Scientific investigation and reasoning. The student knows how to use a variety of tools and safety equipment to conduct science inquiry. The student is expected to:

(A) use appropriate tools to collect, record, and analyze information, including journals/notebooks, beakers, Petri dishes, meter sticks, graduated cylinders, hot plates, test tubes, triple beam balances, microscopes, thermometers, calculators, computers, timing devices, and other equipment as needed to teach the curriculum; and

(B) use preventative safety equipment, including chemical splash goggles, aprons, and gloves, and be prepared to use emergency safety equipment, including an eye/face wash, a fire blanket, and a fire extinguisher.

August 22-29, 2011

Rules and procedures, social contract, preparation and organization of science notebooks. Here is your chance to be creative! Each student will need to have their science notebook (composition book) with them in class each day and also review it each evening.

August 30-September 2, 2011

Discussion of lab safety, tour of science lab, and quiz. Examples of science equipment, what each measures, and activity page.

September 6-7, 2011

Test over lab safety and science equipment. Review lab safety quiz and equipment workshe
