1 – 6 of 6 Classroom Resources

• Melting Point, Phase Changes, Heat | Elementary School

### Lesson Plan: Chocolate Changes

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.

• Physical Properties, Melting Point, Phase Changes, Boiling Point | Elementary School, Middle School

### Lesson Plan: Investigating Water's States of Matter

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.

• Observations, Physical Properties, Melting Point, Phase Changes, Scientific Method | Elementary School

### Lab: Ice Cube Race

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.

• Observations, Melting Point, Phase Changes, Introduction, Physical Change | Elementary School

### Lesson Plan: Let's Get Physical About Water

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.

• Density, Physical Properties, Melting Point, Freezing Point, Phase Changes, Physical Change, Molecular Motion, Freezing | Elementary School

### Lesson Plan: Pothole Science

In this lesson, students investigate how the density and therefore the volume, of water changes when it freezes.

• Density, Melting Point, Inferences, Elements, Periodic Table, Matter, Chemical Properties | Elementary School

### Lesson Plan: Mystery Metals

In this lesson, students will make measurements, calculations, and inferences to help solve a mystery about the identity of an unknown metal.
