The Cycle of Matter
An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form.

Conservation of Mass
Students conduct an experiment to compare the total mass of products to the mass of reactants. In this conservation of mass lesson plan, students devise an experiment to show that matter is neither created or destroyed in a chemical...

Activit #2 Matter: Is It Conserved?
Students support the law of conservation of matter with evidence. They discuss the changes observed from the burning of the candle, and the differences in mass which are observed when the same reaction is carried out in an open or...

Conservation of Mass
How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

The Conservation Of Mass (The Mass Of Gas)
Students gain an understanding of matter in all of its phases. In this science lesson plan, students further their knowledge of the laws of conservation of mass, the loss in mass can be accounted for, when the gas is allowed to escape...
Curated OER
States of Matter Mini-Unit
Students identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.

Conversation about Conservation
Students explore areas of conservation. In this conservation lesson, students are divided into groups and learn the terms indiscriminate, conservationists and preservationists. Students discuss which group is the wisest and makes the...

Energy Conservation
Third graders discuss four points related to conservation. They work in groups to design a package to keep an ice cube from melting to demonstrate the concept of insulation. They then make a chart that shows which materials used did the...

Melting and Freezing of Water
Learners examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Activity #5 Environmental Effects
Young scholars explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are...
Curated OER
Model Mania
Eighth graders study the conservation of matter. In this chemical reaction lesson students examine what happens during a chemical reaction and complete a lab activity.
Science 4 Inquiry
Maintaining Mass
Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Sorting Plastics For Recycling
First, young chemists practice polymer identification by density and flame tests. With the data collected, they propose a method of separating polyethylene from other plastics and determine what property makes it desirable for recycling....
Cornell University
Chemical Reactions
Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Money Matters to Me
Fourth graders explore economics by identifying financial goals. In this consumerism lesson plan, 4th graders discuss money matters and how to conserve an income when they get older in order to achieve their goals. Students collaborate...

Spectroscope
Learners examine how to apply conservation of energy and properties of matter to a spectroscope. In this energy lesson students build their own spectroscope and observe three kinds of spectra.

Balancing Bottles
Students explore the Law of Conservation of Matter using effervescent tablets. In this mass and energy lesson, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will discuss and...

Chemical Composition of American Coins
Students investigate the chemical composition of pennies dated 1983 or later. In this chemical composition of American coins lesson plan, students scratch the surface of the penny to expose the zinc core. They put the penny in...

What Influences Reaction Rate?
Students study reaction rates, what determines how fast a reaction happens and how the chemical changes occur. In this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create a graph...
