Matter and Its Interactions

Lesson 3- The Ups and Downs of Thermometers

Grade 5

Students will look closely at the parts of a thermometer. After placing a thermometer in hot and cold water, students will look at molecular model animations of the liquid in a thermometer. Students will then draw a model of the molecules of a thermometer after it has been placed in hot and then cold water.

Lesson 2- Molecules in Motion

Students add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules. Students watch molecular model animations to see the effect of heating and cooling on the molecules of a liquid. Students will also draw their own molecular model.

Unit Test

Lesson 4- Moving Molecules in a Solid

Questions unit based on experiments, observations, and content learned throughout the unit. Questions are taken from activities and evaluations in lessons. Many questions use diagrams and pictures to help students recall what experiments were completed. Students will also be asked questions and have to apply knowledge they learned to other situations and content areas.

Students will see a demonstration with a metal ball and ring showing that heat causes atoms to spread a little further apart. They will also see that cooling a solid causes the atoms to get a little closer together. The same rules they discovered about liquids also apply to solids.

Lesson 1- Molecules Matter

Students discuss the meaning of “chemistry” and “matter”. Students investigate a drop of water hanging from a dropper and drops of water beading up on wax paper. They also look at a molecular animation that models the motion of water molecules. Students are introduced to the idea that matter is made up of extremely tiny particles that are attracted to one another.

Matter and Its Interactions

Overall Goals

5th Grade

In This Unit

  • Five lessons and and a final assessment
  • Each containing an engaging activity or experiment for the students to complete to gain a better conceptual understanding of matter and its interactions.
  • Students are introduced to the idea that matter is composed of atoms and molecules that are attracted to each other and in constant motion. Students explore the attractions and motion of atoms and molecules as they experiment with and observe the heating and cooling of a solid, liquid, and gas.
  • Lessons also include teacher demonstrations and online interactive activities.
  • Each lesson has a complimentary activity sheet and a brief formal assessment.
  • At the end of the unit, students will complete a final assessment that asked students to analyze and evaluate the concepts tested in the unit

Rationale

Each lesson addresses misconceptions students may have about matter and provides students with experiences and demonstrations to combat their misconceptions. Students are also evaluated each lesson to track any misconceptions that may come about during instruction. The nature of this lesson is to predict, prevent, and change misconceptions students hold about matter by providing them with experiences that allow them to reformulate their ideas and construct new pathways in their understandings.

by Megan Vona

  • 1. Observer and describe water on the molecular level using the idea that water is composed of tiny molecules that are attracted to one another.
  • 2. Explain, on a molecular level, how heating and cooling affect molecular motion (liquids and gasses)
  • 3. Students will describe, on the molecular level, why the liquid in a thermometer goes up when it is heated and down when it is cooled
  • 4. Describe gas as matter on the molecular level

Lesson 5- Air, It’s Really There

This lesson focuses on molecular motion in gases. Students compare the mass of a basketball when it is deflated and after it has been inflated. The inflated ball has the greater mass so students can conclude that gas is matter because it has mass and takes up space. Then students consider how heating and cooling affect molecular motion in gases. They dip the mouth of a bottle in detergent solution and observe a bubble growing and shrinking when the bottle is warmed and cooled. Students will learn that the attractions between gas molecules are so minimal that attractions can’t be used to explain the behavior of gases like it can for liquids and solids.
