    • create a law related to tubes

    • THEORIES NEVER BECOME LAWS

  • Quiz

    • How do we know we have the right answer in science?

    • Describe the differences between hypothesis, theory, and law

    • Go over folders, create table of contents

    • Matter is the "stuff" that makes up our world. Anything that has mass and takes up space is matter
