TASC Physical Sciences Level 3 study guide
TASC Physical Sciences Level 3 · Work through your exam, one topic at a time.
Physical Sciences (TASC Level 3) is a Tasmanian senior secondary course credential, and this independent study page is designed for candidates preparing for its external assessment, whether they are school students, home learners, or adults returning to study. The exam is expected to draw on four broad strands: scientific inquiry and investigation skills; physics covering motion, forces and energy; chemistry covering materials, reactions and atomic structure; and Earth and space sciences with interdisciplinary applications. Each strand is weighted at roughly one quarter of the course, so a balanced study plan matters more than deep specialisation in one science. Preparation should begin with the official TASC course documents, which set out the current syllabus, assessment requirements and any practical work expectations. The TASC Physical Sciences Level 3 study guide has 4 sections and about 1,311 words.
01Scientific Inquiry and Investigation Skills
Every TASC inquiry question asks you to think like a researcher: what is being compared, what is held constant, and what evidence would settle the question? A strong investigation states a testable hypothesis, identifies one independent variable (the factor deliberately changed), one dependent variable (the measured outcome), and lists controlled variables kept the same so the comparison is fair.

Speed is distance divided by time; velocity adds direction; acceleration is the change in velocity per unit time. On a distance-time graph, slope is speed; on a velocity-time graph, slope is acceleration and the area under the line is displacement.

Atoms have protons and neutrons in the nucleus and electrons in shells. Atomic number is the proton count and defines the element; mass number is protons plus neutrons.

Earth science links the geosphere, atmosphere, hydrosphere, and biosphere. The rock cycle explains how igneous, sedimentary, and metamorphic rocks transform through melting, weathering, deposition, and heat and pressure.
