WHAT ARE THE STATES OF MATTER?
Sensors connected to the Piper Computer Kit provide students with educational hands-on experience that integrates environmental sensory data with unparalleled coding and story adventures.
The Sensor Explorer projects and lessons feature three sensors that you wire up to the Piper Computer. Students will then be guided through character-driven story narratives while using game-like StoryMode to learn how decisions impact final outcomes within three unique StoryMode world puzzles and problems. Coupled with the game experience in StoryMode, students will have fun extending their coding skills using PiperCode while collecting real-world data using the 3 sensors.
In this lesson, students will deepen their understanding of the states of matter and how they are related to particle motion. Students will explore the properties for each state of matter, and will be introduced to the composition of matter as it relates to each state - liquid, gas, and solid.
In this lesson, students will deepen their understanding of the states of matter and how they are related to particle motion.
Develop models that assess the 3 states of matter.
Model and describe how changes in particle motion define a state of matter.
Describe how certain properties of objects determine what phase they’re in under certain pressure and temperature.
Explain how phase changes of matter occur as they relate to temperature and pressure.
LESSON PREPARATION (10 MIN)Ensure students have access to (or you print out copies of) the Lesson 2 graphic organizer.
Teacher-led Discussion (5 minutes)
Consider: Different Forms of Water in Everyday Life
Have students consider the forms of water they encounter through a Think Pair Share warmup exercise.
Provide the following guiding questions:
When do you encounter water?
What form is it?
What do you call it?
Note: Encourage students to draw the different forms of water as they create their responses.
Explore: The Properties for each State of Matter (30-40 minutes)
Share the States of Matter slides with each group from lesson 2 or regroup for this exercise.
Note: As students go through the slides, students should fill in their graphic organizer with their findings.
Explain (10-15 Minutes)
Provide Context: Using Lesson 3 Slides, review the particle images that match a state of matter on slide 2.
Ask students the following questions in a full-class discussion:
- What do you think the white dots represent in these graphics?
- How were you able to decide which graphic represented which state of matter?
- If we were able to get a closer look into each state of water (ice, liquid water, and steam), what do you think we would see?
[ELA optional extension: have students read a portion of this article to gain a deeper understanding of the states of matter.]
Apply: An introduction to the Composition of Matter
Have students read the following (or explain it to them in your own way):
“Water will be liquid between 0 and 100 degrees Fahrenheit, but oxygen will be gas at the same temperatures. This is based on the composition of matter - objects are found in certain states based on the temperature. Why is matter in a particular state at a temperature? (There are certain properties of objects that determine what phase they’re in under certain pressure and temperature.) The composition of matter determines when an object becomes liquid, solid, and gas. That is why our houses don’t melt when it’s hot outside. Temperature plays a part in this, but we will explore that in the next lesson.”
Use Slides 3-5 to discuss with the class.
