Science

Science practices, then three subjects: life science, physical science, and earth and space science.

The Science test takes 90 minutes and has about 34 questions. About four in ten questions are life science, four in ten are physical science, and two in ten are earth and space science.

The science practices run through all three. Nearly every question comes with something to read first: a short passage, a table, a graph, or a diagram. The question then asks what it shows, or what you can fairly conclude from it. So start with the science practices, just below. Then choose a subject.

For every subject

Science Practices

How to read science and reason from evidence. Every question on the test uses these skills.

Science Practices, in orderRead, then practice
  1. Science Practices

    The study guide to read first: reading a science passage, designing a fair test, reading tables and graphs, reasoning from data, numbers and units, and simple statistics and probability.

  2. Change One Thingthis week

    The scientific method as an app you work with your hands: a question, a fair test, and a report others can repeat.

    With it: the Method Wheel, a handout that prints.

  3. Look Again Quizzes 1 to 7

    Seven quizzes on the scientist’s toolkit. Each has a short guide, two worked examples, ten questions, and a key that explains the answers.

  4. Science Drills, Family Inew

    Short sets of ten questions (or five), one skill at a time, numbered in order, with two worked examples first and the reasoning for every answer. Twenty-nine drills are ready: reading a science passage, the scientific method, tables and graphs, diagrams and models, reasoning from data, and numbers and units.
