Competencies 007–010 of the Core Subjects EC–6: Science (904). The competencies TEA lists, how they are tested and practice questions with explanations.
45 questions on the real 55-minute clock, with a score by competency group and an explanation for every answer.
Or start the free Physical Science drillSummarized from the TExES Core Subjects EC–6 (391) preparation manual, Section 3: exam framework, Competencies 007–010. The grouping of competencies into drill sets is ours.
Expect balanced and unbalanced forces, simple machines, physical versus chemical change, conduction, convection and radiation, circuits, and how light and sound travel. TEA lists the competencies without weights, so our practice test spreads its questions evenly across them.
Answer each question, then open the explanation.
Question 1
Which material is a good electrical insulator?
Answer: A: Rubber
Rubber does not let electric current flow easily, so it is used to insulate wires. Metals and salt water conduct electricity.
Question 2
A flashlight changes stored energy in its batteries into
Answer: D: light energy and some thermal energy.
The battery’s chemical energy becomes electrical energy, which the bulb changes into light and some heat (thermal energy).
Question 3
Which simple machine is a ramp used to move a heavy box onto a truck?
Answer: A: An inclined plane
A ramp is an inclined plane: it lets a smaller force move a load upward over a longer distance.
Question 4
Salt water is an example of
Answer: C: a solution.
Salt water is a solution, a mixture in which salt is evenly dissolved in water. The salt and water can be separated by evaporation.

Or start the free Physical Science drillTEA lists the competencies of the TExES 904 without weights or question counts. Our 45-question practice test spreads its questions evenly across the competencies, which gives Physical Science 10 questions.
Competency 007: forces and motion; Competency 008: physical and chemical properties and changes, states of matter, mixtures and solutions; Competency 009: energy and interactions: heat, electricity, magnetism, light and sound; Competency 010: energy transformations and conservation of matter and energy.
Expect balanced and unbalanced forces, simple machines, physical versus chemical change, conduction, convection and radiation, circuits, and how light and sound travel. TEA lists the competencies without weights, so our practice test spreads its questions evenly across them.
