Curated OER
Discovering Physical Changes
Fourth graders determine what is meant by a physical change, and they demonstrate how they can make physical changes. They complete activities at stations that entail changes in color, size, texture, hardness, or state of matter. Using...

Physical and Chemical Changes - Making Toffee
Fourth graders make toffee to observe both physical and chemical changes. They determine what types of changes that are caused by the cooking process and which are chemical, and which are physical. In order to do this they follow a...

Ice Cream Chemical and Physical Changes
Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

Activity #13 Changing The Look of Sugar
Pupils observe what happens when sugar is dissolved in water and when it is heated. They weigh the products after each of the two experiments on a balance scale. Pupils distinguish between physical and chemical changes. Students are...

Activity #15 The Snowy Christmas Tree
Students weigh out the proper amount of silver nitrate and prepare the silver nitrate solution. They observe what occurs when pure copper is added to silver nitrate solution. Pupils determine whether the change in the appearance of...
Curated OER
Activity #18 Decompostion of Baking Soda
Students observe what occurs as baking soda is heated. They explain why a chemical rather than a physical change occurred during the procedure. Pupils identify the tpe of reaction (decomposition). Students conduct a glowing splint...
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
Students 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.

Physical/Chemical Properties of a Burning Candle
Young scholars 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
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.
Curated OER
Physical and Chemical Changes
Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science instructional activity, 6th graders complete 6 experiments about chemical and physical changes. Students examine the...
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
Matter - Chapter 2 Physical Changes
In this matter worksheet, students identify words and match them to their definition. Students identify words dealing with matter, its physical changes, and the effect of heating and cooling matter. This worksheet contains nine...
Curated OER
The Same But Different
Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...
Curated OER
Ice Cream Science
Pupils 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 temperature...
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
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.
