Classroom Resources: States of Matter
1 – 4 of 4 Classroom Resources
Mixtures, Melting Point, Freezing Point, Phase Changes, Freezing Point Depression | Middle School, High 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.
Physical Properties, Melting Point, Phase Changes, Boiling Point | Middle School, Elementary 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.
Chemical Change, Melting Point, Phase Changes, Physical Change, Chemical Change, Scientific Method | 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!
Acids & Bases, Melting Point, Freezing Point, Phase Changes, 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.
