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...

It's heating up—and cooling down—in here! A hands-on lesson allows learners to experiment with melting and freezing butter to observe changes as a substance transitions between liquid and solid form. They also view an animation that...

Third graders experiment with common household liquids and solids. In 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, baking...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson can stand alone, but is best used as part of the...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

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.

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...

Scientists participate in a variety of hands-on experiments in this ten-day unit on the three states of matter. Lessons incorporate literature, a-v materials, and poetry to help young scholars differentiate between solids, liquids and...

Young scholars are introduced to the various states of matter. After watching a video, they discover how to compare the three states using its shape and volume. In groups, they participate in an experiment with solids, liquids and...

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...

Young scholars describe the properties of solids and liquids, and explain how a semiconductor works.  For this atom lesson students demonstrate the bonding properties of carbon and silicon.

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.

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

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

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

Demonstrate how to measure the volume of liquids and solids immersed in liquid to your class. They observe a teacher-led demonstration, and in small groups construct a data table that demonstrates how many marbles were used and the...

From solid to liquid and then back again. Young scientists  dissolve salt in water and then evaporate the water while observing what happens to the solute. They use their observations to make predictions about other solutions.

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 explore various states of matter. In this science lesson plan, students recognize the properties of each state of matter and recognize the similarities and differences between the three states of matter.

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 identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe what happens when they try to put two kinds of matter into the same space and conclude that solids, liquids, and gases occupy space.

Second graders identify and describe properties of matter. They identify three forms of matter- solids, liquids, and gases with 100% accuracy. The student describes the properties of solid objects.

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.

Young scholars 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...
