Classroom Resources: States of Matter
1 – 13 of 13 Classroom Resources
Phase Changes, Melting Point, Heat | Elementary School
In this lesson, students will review what they know about the three states of matter (solid, liquid, and gas). They will perform a word sort about states of matter and discuss how substances can exist in more than one state of matter. Following this they will contribute to a KWL (Know, Want to know, Learned) chart. The teacher will conclude the lesson with a demonstration using chocolate.
Intermolecular Forces, Polarity, Molecular Geometry, Melting Point, Boiling Point | High School
In this activity, students will be able to understand the strength of the attractions of the three intermolecular forces (IMFs) and use this information to help identify physical properties of molecules (such as melting point, boiling point or states of matter).
Heat, Law of Conservation of Energy, Specific Heat, Temperature, Calorimetry, Phase Changes, Boiling Point, Melting Point, Heating Curve, Intermolecular Forces, Molecular Motion, Phase Diagram | High School
The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach the Phase Changes and Heat Transfer to your students.
Freezing Point Depression, Mixtures, Phase Changes, Freezing Point, Melting Point | High School, Middle School
In this lab, students will consider why salt is used to aide in snow clearing and to help keep icy roads safe. They will investigate how salt ‘melts’ ice and determine the best type of salt to do so. Additionally, students will explore the advantages and disadvantages of the various different types of salt.
Phase Changes, Boiling Point, Melting Point, Physical Properties | Elementary School, Middle School
In this lesson, the students will identify properties of different states of matter, and then work in groups to model molecular arrangement in the solid, liquid, and gaseous states of water. This lesson will also help students to understand that the change in state as a physical change and how the solid state of water has unique properties.
Ionic Bonding, Covalent Bonding, Melting Point, Molecular Structure | High School
In this lab, students will compare two seemingly similar substances, salt and sugar. Through melting a sample of each substance and analyze of their chemical composition, students will draw conclusions regarding ionic and covalent compounds.
Chemical Change, Physical Change, Chemical Change, Scientific Method, Melting Point, Phase Changes | Middle School
In this lab, students will be able to demonstrate the difference between a physical and chemical change by making ooey, gooey, yet yummy S’mores!
Phase Changes, Physical Change, Melting Point, Introduction, Observations | Elementary School
In this lesson, students will learn about the phase changes of matter. During the course of two days students will perform several short experiments in order to change the state of water and they will record their observations.
Phase Changes, Physical Properties, Melting Point, Observations, Scientific Method | Elementary School
In this lab, students will investigate what factors can influence the change in state of matter from a solid to a liquid. They will have the opportunity to make a hypothesis and participate in the design and completion of an experiment.
Physical Change, Intermolecular Forces, Heating Curve, Phase Changes, Graphing, Heat, Exothermic & Endothermic, Temperature, Freezing Point, Melting Point | High School
In this lab, students will create a phase change graph by adding and removing heat to observe and record data during actual phase changes.
Freezing Point, Melting Point, Phase Changes, Acids & Bases, Physical Change | Middle School
In this lesson, students investigate how stearic acid undergoes a phase change from solid to liquid and back from liquid to solid. Temperature readings will be collected at one-minute intervals once the acid melts, the heat escapes, and the acid cools. Students are introduced to the idea that energy loss does not always result in a continuous temperature drop.
Freezing Point, Density, Freezing, Phase Changes, Melting Point, Molecular Motion, Physical Change, Physical Properties | Elementary School
In this lesson, students investigate how the density and therefore the volume, of water changes when it freezes.
Melting Point, Elements, Matter, Density, Chemical Properties, Periodic Table, Inferences | Elementary School
In this lesson, students will make measurements, calculations, and inferences to help solve a mystery about the identity of an unknown metal.
