8th Grade Lesson Plans: 1st Six Weeks

LABORATORY SAFETY/SCIENCE EQUIPMENT

TEKS OBJECTIVES:
(1) Scientific investigation and reasoning. The student 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.
August 22 – Sept. 2, 2011

INSIDE THE ATOM – CHAPTER 2

TEKS OBJECTIVES:
(5) Matter and energy. The student knows that matter is composed of atoms and has chemical and physical properties.
The student is expected to:
(A) describe the structure of atoms, including the masses, electrical charges, and locations, of protons and neutrons in
the nucleus and electrons in the electron cloud;
(B) identify that protons determine an element’s identity and valence electrons determine its chemical properties,
including reactivity;
(C) interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements.
Sept. 6 – 29, 2011
