Facts and Definitions
Lesson 1: What Is the World Made Of?
- Everything in the world is made of matter.
- Matter is anything that has mass (weight) and takes up space.
- Matter comes in three states: solids, liquids, and gases.
Lesson 2: Solids
- Solids keep their shape and size unless we change them in some way.
Lesson 3: Liquids
- Liquids take the shape of their container.
- Liquids can be poured.
Lesson 4: Bartholomew and the Oobleck
- A true statement is one that describes something that did happen or can be proven.
- A false statement is not true or can be proven wrong.
Lesson 5: Comparing Matter
- A noun is a person, place, or thing.
- Adjectives are words that describe people, places, or things.
- Molecules are the very small pieces of matter that combine to make a larger amount of the same matter.
- The molecules in solids are close together, in liquids farther apart, and in gases even farther apart.
Lesson 6: Changes in States of Matter
- States of matter can change.
- Temperature can change the state of matter.
Lesson 7: Exploring Solids and Liquids
- Solids are made from a variety of materials.
- Some solids are found in nature and some are made when people combine materials.
Lesson 8: Our Bodies and Our World
- Our bodies contain solids, liquids, and gases.
