Study-map shares describe the learning resources on this page. They are not presented as official test percentages.
Effortless Math
Use this page as your home base for the Science section: learn the content in a clear order, practice under a timer, and turn every missed question into a focused review plan.
Start with the right target
The Science section rewards more than memorization. Build a working picture of body systems, cells, chemistry, and evidence-based reasoning. Then practice reading diagrams, tables, graphs, and short experiments carefully before choosing an answer.
Your Science study map
Human Anatomy & Physiology
Learn structures, functions, pathways, homeostasis, and how systems affect one another.
Biology
Review cells, transport, genetics, cell division, microorganisms, and biological molecules.
Chemistry
Master atoms, matter, bonding, reactions, solutions, acids, bases, and pH.
Scientific Reasoning
Practice variables, controls, hypotheses, data interpretation, accuracy, conclusions, and predictions.
Study one Science topic at a time
Each lesson opens in a new tab and gives you a clear definition, an original visual, a worked example, a common-mistake check, practice with answers, and a short teaching video.

How to use your book and practice tests
- Learn one focused topic. Read the lesson, redraw the important pathway or diagram, and explain it aloud in plain language.
- Complete the chapter practice before checking answers. Mark the question type that caused the miss: content, visual reading, calculation, or reasoning.
- Use the two print forms as timed checkpoints. Complete all 50 questions before opening the shared answer key and explanations.
- Use the online companion forms from your book. The access page and QR cards in the book open ten full-length private practice forms without placing their addresses on a public page.
- Review patterns, not just answers. Revisit the lesson behind each repeated error and retest yourself the next day.

ATI TEAS Science Flashcards
Say the meaning aloud before you open each card. A quick daily review of these ideas helps the vocabulary stay connected to the science behind it.
Homeostasis
The body’s tendency to keep internal conditions, such as temperature or blood glucose, within a stable range.
Diffusion
The net movement of particles from an area of higher concentration to an area of lower concentration.
Osmosis
The diffusion of water across a selectively permeable membrane.
Artery
A blood vessel that carries blood away from the heart; it does not always carry oxygen-rich blood.
Mitosis
Cell division that produces two genetically matching body cells for growth and repair.
Independent variable
The factor a researcher deliberately changes in an experiment.
Dependent variable
The measured result that may change in response to the independent variable.
Control group
A comparison group that does not receive the experimental change.
pH
A scale that describes how acidic or basic an aqueous solution is.
Accuracy
How close a measurement is to the accepted or true value.
Precision
How close repeated measurements are to one another.
Correlation
A relationship in which two variables change together; by itself, it does not prove cause and effect.
When a question feels difficult
Slow down and identify what the question is really asking. For a diagram, table, or graph, read its title, labels, legend, and units first. For a body-system question, trace the path or cause-and-effect chain. For an experiment, name what changed, what was measured, and what stayed controlled. These small routines turn unfamiliar questions into manageable evidence problems.
