These are the Texas Essential Knowledge and Skills (TEKS). Each line describes what students are expected to know and be able to do by the time they take the STAAR assessment. I have bolded the skill portion of each student expectation to highlight what students must demonstrate. 

Equal & Unequal Forces

5.7A The student is expected to investigate and explain how equal and unequal forces acting on an object cause patterns of motion and transfer of energy

Conducting Investigations

5.7(B) design a simple experimental investigation that tests the effect of force on an object in a system such as a car on a ramp or a balloon rocket on a string

Energy Transformation

 5.8A investigate and describe the transformation of energy in systems such as energy in a flashlight battery that changes from chemical energy to electrical energy to light energ

Circuits

 5.8B demonstrate that electrical energy in complete circuits can be transformed into motion, light, sound, or thermal energy and identify the requirements for a functioning electrical circui

Light

5.8C demonstrate and explain how light travels in a straight line and can be reflected, refracted, or absorbed
