Double displacement reactions occur between aqueous solutions of ionic compounds. A precipitate can be seen if the reaction occurs. Common precipitates often range in color from white to yellow. Combustion reactions always occur between a hydrocarbon and oxygen usually in the air.
As you would imagine, heat and light are produced and the resulting products are carbon dioxide gas and water vapor. Note: Considering time and student ability, have students group objects in two or three different ways and then record their groupings on the Student Activity Sheet. For students with fine motor issues for whom writing is difficult, you may want to provide cut-out words that can be pasted in place on the Student Activity Sheet.
Explain to students that you could also group the animals according to size. Cows are largest, cats are smallest, and dogs are in the middle. You could also group the animals according to whether they are farm animals or house animals.
Dogs and cats are house animals and cows are farm animals. When you go home today, write down or draw three different objects that have at leastone property in common.

Lesson 1. Inquiry in Action. Lesson Overview for Teachers View the video below to see what you and your students will do in this lesson. Objective Students will develop an understanding that objects and materials have characteristics or properties. Key Concepts Objects and materials have different characteristics or properties.
The properties of materials include features such as color, size, and shape; whether theyare rough or smooth, shiny or dull, hard or soft, and flexible or stiff. Objects and materials can be sorted into groups based on the properties they have in common. Objects and materials can be grouped in different ways depending on the properties used to group them.
After working with a simulation to help students understand the meaning of properties and characteristics, students are given a variety of small common objects to sort based on observable properties. Working in groups, students sort objects and record their groupings on the Activity Sheet. Students are then guided to come up with different criteria for one more set of groupings.
Students participate in a class discussion of the different properties used to make the groupings. Safety This lesson uses common classroom or household materials that are considered nonhazardous. Materials for the demonstration Shell, leaf, or pine cone Plastic container lid Coin Metal key Teacher Preparation Materials Zip-closing plastic sandwich bags Copier paper Construction paper Aluminum foil Cut the wax paper, plastic sandwich bag, copier paper, construction paper, and aluminum foil into approximately 5"x 5" squares.
Engage 1. Ask students to suggest a way of sorting the objects shown. Guide students to use different observations of properties to group a plastic lid, a coin, and a metal key in different ways. Use the board to write down the objects and some of their properties.
