TEAS Science
Connect anatomy, biology, chemistry, and scientific reasoning so that science questions become easier to analyze and recall.
10 focused Science guides
- TEAS Science Study Guide: Anatomy, Biology, Chemistry, and ReasoningStudy TEAS Science by organizing facts into systems and cause-and-effect pathways. Begin with human anatomy and physiology, then connect cell biology, genetics, chemistry, and scientific reasoning. Use diagrams, retrieval, and unfamiliar questions to practice explaining what changes, why it changes, and which evidence supports the conclusion.
- Anatomy and Physiology for TEAS Science: A System-by-System MethodLearn anatomy and physiology as a set of coordinated systems, not separate organ lists. For every system, know its primary purpose, major structures, movement pathway, control signals, and connection to homeostasis. Then practice predicting how a change in one part affects the next step and another system.
- Cardiovascular System for TEAS Science: Blood Flow and FunctionTrace blood from the body through the right side of the heart to the lungs, then through the left side of the heart to the body. Know which valves preserve one-way flow, how arteries and veins are defined by direction, and why thin capillary walls support exchange. Connect blood components to transport, defense, and clotting.
- Respiratory System for TEAS Science: Ventilation and Gas ExchangeDistinguish ventilation from gas exchange. Ventilation moves air through pressure changes created mainly by the diaphragm and chest volume. At alveoli, oxygen and carbon dioxide diffuse in opposite directions according to concentration or partial-pressure differences. Circulation then transports the gases between lungs and tissues.
- Digestive System for TEAS Science: Digestion, Absorption, and OrgansTrace food through the mouth, esophagus, stomach, small intestine, and large intestine. Distinguish mechanical breakdown from chemical digestion, and remember that most nutrient absorption occurs through the small intestine. Connect accessory organs such as the liver, gallbladder, and pancreas to the substances they produce, store, or release.
- Cell Structure and Function for TEAS ScienceStudy cells by linking each structure to a process. The membrane regulates exchange, the nucleus stores genetic information, ribosomes build proteins, the endoplasmic reticulum and Golgi apparatus process and route products, mitochondria support ATP production, and lysosomes participate in breakdown. Practice transport and protein pathways rather than isolated labels.
- Genetics, DNA, and Inheritance for TEAS ScienceOrganize genetics from molecules to outcomes. DNA contains genes arranged on chromosomes. Cells copy DNA before division, use gene information through transcription and translation, and pass allele combinations through reproduction. Use Punnett squares as probability models, not guarantees for a small family.
- Chemistry Basics for TEAS Science: Atoms, Bonds, Reactions, and pHBuild TEAS chemistry from particles and conservation. Know how protons, neutrons, and electrons relate to atoms and ions; how electron behavior influences bonds; how reactions rearrange atoms; and how concentration, temperature, catalysts, acids, and bases affect chemical systems. Use particle-level explanations instead of memorizing disconnected trends.
- Scientific Method and Experiments for TEAS ScienceAnalyze an experiment by naming what is changed, what is measured, what is held constant, and which comparison supports the claim. Then evaluate sample selection, repeated trials, measurement quality, and possible confounding variables. A valid conclusion must stay within the population, conditions, and outcome actually studied.
- Graphs, Data, and Scientific Reasoning for TEAS ScienceInterpret scientific data by reading the title, axes, units, scale, categories, and legend before looking at answer choices. Identify the requested comparison, use the relevant values, and separate an observed trend from an explanation of why it occurred. Consider variability and sample size when the figure provides them.
