Recognizing and Describing Chemical Changes
Seventh graders distinguish between physical and chemical changes in both natural and technological settings. They identify the reactants and products for a given chemical reaction. they then write simple chemical equations given the...
Curated OER
Properties of Matter
Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...
Curated OER
Chemical Changes
Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.
Curated OER
Reversible and irreversible changes
Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.
Curated OER
How to identify a physical change from a chemical change
Young scholars identify the difference between some physical and chemical properties and compare some physical and chemical changes. They design an experiment to distinguish between a physical or a chemical property of their choice.
Curated OER
Changes in Matter
Eighth graders, in groups, explain the difference between physical and chemical changes.
Curated OER
Physical/Chemical Properties of a Burning Candle
Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.
Curated OER
Boom and Fizz
Students investigate the differences between a physical and chemical change. They observe various demonstrations involving physical or chemical changes, make predictions, and record what they see, hear, and smell.
Curated OER
Substances And Chemical Reactions
Students watch and predict chemical reactions when different substances are mixed together. They differentiate between solid, liquid, and gas.
Curated OER
Striking it Rich with Chemistry
Learners identify the composition of different pennies. In this chemistry lesson, students use a post 1982 penny to observe chemical change. They explain how to turn a penny from copper to gold.
Curated OER
Candle Observations
Students view a demonstration and record and questions and observations that they have. In this candle lesson students discuss their observations and give examples of the changes they saw.Â
Curated OER
Physical and Chemical Changes
Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science lesson, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...
Curated OER
Matter
Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.
Curated OER
Food Matters
Fifth graders identify physical and chemical changes. In this science inquiry lesson, 5th graders observe the changes that occur when making bread and butter. Students explain if the product is result of a physical or chemical change.
Curated OER
Matter
In this matter worksheet, students complete a graphic organizer by describing the properties of matter, the changes of matter, and how matter can form mixtures.
Curated OER
What Are Types of Chemical Reactions?
In this chemical reactions worksheet, students will brainstorm different types of chemical reactions and then write a brief description of each one.
Curated OER
Ice Cream Science
Young scholars review properties of matter and discuss how materials change when things are done to them. They observe how materials change as a reaction to temperature by following the procedure to make ice cream and recording the...
Curated OER
Activity #20 Tear An Aluminum Can In Half
Students observe the chemical reaction between CuCl2 and aluminum. They identify the evidence for a chemical change. Pupils answer the following questions after observing the experiment: How do you know a chemical reaction occurred?,...
Curated OER
Matter And Its Changes
Fifth graders explore the phases of matter, make observations of matter, the physical and chemical properties of matter, solutions and mixtures, formation of molecules and atoms and molecules all through hands on activities.
Curated OER
Salt and Water Divorce by a Physical Change
Students discuss the definitions of physical and chemical properties and changes. They vaporize a solution of salt and water, observing the sodium chloride that is left behind.
Curated OER
Physical and Chemical Changes
Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.
Curated OER
Laboratory - Density of a Material
Middle schoolers conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.
Curated OER
Salt, To Use or Not To Use
Fifth graders develop a deeper understanding of chemical and physical changes. They explain how salt is made, used, and the affects it has on the body. They explain that salt in moderation is important to our health.
