7th/8th Science Syllabus - OCTOBER

TEKS TAUGHT:

7th Grade --  

7.7A Calculate average speed using distance and time measurements from investigations

7.7B Distinguish between speed and velocity in linear motion in terms of distance, displacement, and direction

7.7C Measure, record, and interpret an object’s motion using distance-time graphs

7.7D Analyze the effect of balanced and unbalanced forces on the state of motion of an object using Newton’s First Law of Motion

7.8A Investigate methods of thermal energy transfer into and out of systems, including conduction, convection, and radiation.

7.8B Investigate how thermal energy moves in a predictable pattern from warmer to cooler until all substances within the system reach thermal equilibrium

8th Grade -- 

8.7A Calculate and analyze how the acceleration of an object is dependent upon the net force acting on the object and the mass of the object using Newton’s second law of motion

8.7B investigate and describe how Newton’s three laws of motion act simultaneously within systems such as in vehicle restraints, sports activities, amusement park rides, Earth’s tectonic activities, and rocket launches

8.8A compare the characteristics of amplitude, frequency, and wavelength in transverse waves, including the electromagnetic spectrum 

8.8B Explain the use of electromagnetic waves in applications such as radiation therapy, wireless technologies, fiber optics, microwaves, ultraviolet sterilization, astronomical observations, and X-rays

8.9A Describe the life cycle of stars and compare and classify stars using the Hertzsprung-Russell diagram
