ChromaCool!
Fifth graders watch a video about physical and chemical changes. In groups, they participate in a variety of activities involving color. They write their observations in a journal. To end the instructional activity, they use a...
Curated OER
Nothing New? A Physical Change
Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the instructional activity, they review the steps of the water...
Curated OER
Science Detectives
Fifth graders examine the differences between chemical and physical changes. As a class, they are read a scenerio and determine whether it was deliberate act or not. In groups, they observe the changes of an alka-seltzer tablet and...
Curated OER
Changes in Nature
Fifth graders explore changes in nature. They identify chemical and physical changes in the water cycle, carbon cycle, and weathering. Students explore a chemical or physical change based on a chemical formula. They examine the effects...
Curated OER
Physical Changes and States of Matter
Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...
Curated OER
Physical Changes and States of Matter- Two
Third graders explore the concept of evaporation as they observe how the water level changes in a cup that is left out. Working in groups they observe physical changes in a group of everyday items. They record the changes in shape, size,...
Curated OER
Physical and Chemical Properties
Students study the difference between physical and chemical properties. They also discuss changes in matter, known as physical and chemical changes. They observe and discuss several demonstrations of both physical and chemical changes
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...

Activity #13 Changing The Look of Sugar
Students 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...
Curated OER
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
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 plan students discuss their observations and give examples of the changes they saw.
Curated OER
Food Matters
Fifth graders identify physical and chemical changes. For 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
Ice Cream Science
Students 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...
