Young scholars explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.

Third graders study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

Third graders experiment with common household liquids and solids. For this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour,...

Second graders identify the three states of matter by examining fishbowls with various contents. They discuss their observations and the characteristics of matter in each state. Pupils read the story The Rainbow Fish and look for...

Students are introduced to the basic states of matter: solids, liquids and gases. Through experimentation, students determine that liquids and solids have definite volume, that gases do not have definite volume, and that solids have a...

Students review the vocabulary terms solid and liquid. They also review that adjectives tell what kind, which one, and how many. The teacher introduces a "Oobleck" after reading "Bartholomew and the Oobleck" by Dr. Seuss. The students...

Fourth graders define the term matter. They compare properties of solids, liquids, and gases. They describe how matter changes from one state to another. They classify objects as either solid, liquid, or gas.

Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...

Students explore solid, liquids, and gases. In this science lesson plan, students distinguish similarities and differences of matter and recognize that different states of matter may appear in one substance.

Students conduct an online experiment to discover what happens to solids, liquids and gases in different temperatures. In this states of matter instructional activity, students get into pairs and work in a virtual...

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

Students examine the properties of solids, liquids, and gasses. In this states of matter lesson, the teacher guides students through a series of experiments to illustrate each state of matter and how matter changes from one state to...

Students identify the properties of the three states of matter and observe the movement of Oobleck and be able to compare its movement to that of solids and liquids. They record in their Science Journal what they discovered about Oobleck.

After having a class discussion on the three states of matter, young scientists utilize the wonderful substance, Oobleck in order to experience something that changes states of matter. They also create "sparkle jars" which...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Students explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

First graders are read a story about the various stages of matter with a focus on gases. Using a ziploc bag, they capture as much air as possible and discuss how it takes up space even though it is invisible. To end the activity, they...

Students explore solids, liquids, and gases. In this states of water activity, students conduct a scientific investigation that requires them to observe and note the differences among solid, liquids, and gases.

Second graders observe matter in all 3 states : liquid, solid and gas, in an ice cream soda. In teams, they are given ice and teams compete to be the first to melt their ice. Winner gets the ice cream soda. They draw examples of 3 states...

Students construct models of the way water molecules arrange themselves in three physical states - solid, liquid, and gas. They explain the molecular behavior of ice, water, and water vapor.

Students explore the three states of matter. In this matter lesson, students are shown a variety of examples and decide whether it is a liquid, solid or gas. Students brainstorm what characteristics the objects in each group share.

Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...
