Day 3 of 30
Properties of matter: mass and volume
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will be able to explore properties of matter and mass and volume.
In this lesson, we'll explore properties of matter: mass and volume. Scientific inquiry allows us to investigate and explain natural phenomena.
Matter is anything that takes up space and has weight. Matter exists in three main forms (called states): solid, liquid, and gas. A solid keeps its shape (like a rock or ice cube). A liquid flows and takes the shape of its container (like water or juice). A gas spreads out to fill its container (like air or steam). Matter can change from one state to another when heated or cooled!
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.
Anything that has mass and occupies space
The amount of three-dimensional space occupied
Instructions
Materials Needed
- Lab notebook
- Investigation materials
- Safety equipment if needed
Name one example of each: solid, liquid, gas.
What happens to ice when it gets warm?
Why does a balloon float when filled with helium?
Teaching Tip
For this age group: Balance direct instruction with collaborative activities. Allow students to explain their thinking and make connections to prior knowledge when exploring properties of matter: mass and volume.
