States of Matter
Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

Mighty Molecules
Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...
Curated OER
Solid, Liquid, and Gas
Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

Gas Laws and Alka-Seltzer Rockets
Students investigate the Ideal Gas Law. In this three states of matter lesson, students create Alka-Seltzer rockets using film canisters. Students record observations and data according to the scientific method and explain the gas...

Introduction to the States of Matter
Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Matter on the Move
Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Molecules Matter
Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson plan introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a chemistry...

What’s Up with Matter?
Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation. The...

States of Matter
Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it takes to...
Curated OER
Matter
In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

Properties of Matter
A collection of ten slides reveals bright graphics and photos. Though the title is "Properties of Matter," the content is incoherent. You will find a couple of slides on chemical reactions, a few on the example of the S.S. Hindenburg...

Endothermic and Exothermic Reactions
Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical composition...
Curated OER
Particle Model of Solids, Liquids, and Gases
Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...

A Chemist in My Class?
First graders in kindergarten science class discuss matter. They make predictions and then identify mystery items in brown paper bags as either solid, liquid, or gas by using their senses. They discuss that a chemist is a scientist that...
Curated OER
Physical Changes to Matter
Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Matter Matters: Solids, Liquids and Gases
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 students differentiate between solids, liquids and gases.
Curated OER
Matter: Solids Liquids and Gases
Students participate in a science experiment to understand that matter takes up space. In this matter lesson, students experiment with solids, liquids and gases to recognize that matter is everywhere. Students make observations and...
Curated OER
Mixtures of Matter
Students experiment with solids and liquids. In this mixtures of matter lesson, students combine matter to form solutions. Students hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by having...
Curated OER
Mixtures of Matter
Students experiment with mixtures of matter. In this matter lesson, students investigate which liquids form a solution when mixed together and which do not. Students also identify which solids can be separated from matter.

Gas Stoichiometry
In this gas stoichiometry worksheet, learners use the ideal gas law and balanced chemical equations to solve for unknown values such as volume and mass of gases.

The States of Matter
In this states of matter learning exercise, students learn about the 3 different states of matter and how matter shifts states. They then answer the 20 questions in the packet. The answers are on the last page.

States of Matter
For this states of matter worksheet, students are given 15 statements and they fill in the blank with terms related to solids, liquids and gases and the transition from one state to another. Students use the clues to complete a crossword...
Curated OER
Matter in Motion
Second graders examine matter, what it is and what the different states are. In this matter lesson students view The Magic School Bus Meets Molly Cule and answer questions.

The Physical Behavior of Matter
Students distinguish between three phases of matter: solid, liquid and gas, on the molecular level. They compare and predict the relative compressibility of the three phases of matter through journal writings and drawings.
