Learners 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 forms of water and observe how it changes from a solid to a liquid to a gas. The concepts of condensation, evaporation and the introduction to the water cycle form the basis of this lesson plan.

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...

Students complete activities to study the properties of solids and liquids. In this states of matter lesson plan, students investigate the melting and freezing of a range of materials in a virtual experiment. Students melt the substances...

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

Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

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...

Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

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...

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 predict if icebergs melting has an effect on the sea level rising.  In this global warming lesson plan students complete an experiment to see the effects of melting icebergs and write a conclusion on their data collected.

Third graders discuss and demonstrate how water has three forms: solid, liquid, and gas. They create a snow figure outdoors or freeze ice in molds and predict how long it will take for real solid water (snow sculpture or ice) to become...

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

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 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...

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...

Seventh graders investigate the particulate level of solids, liquids, and gases. They examine how the particle method show the interplay between scientific theories and evidence.

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...

Students watch and predict chemical reactions when different substances are mixed together. They differentiate between solid, liquid, and gas.

Students determine the effect of temperature on the motion of particles. They study the difference between particles in a gas, liquid, and a solid and see how the characteristics of solids, liquids, and gases can be explained by particle...

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

Students investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...
