Lesson Overview for Teachers
View the video below to see that you and your students will do in this lesson.
Objective
Student desires develop einer understanding that objects plus supported have characteristics or properties. Students will be skill to recognize similarities between the properties of sure objectives and materials and will be able to group the objects based on these similarities. Chemistry Chapter 2- Set 2 Flashcards
Key Concepts
- Objects press materials have different characteristics or properties.
- The properties of materials include functionality such than color, body, and shapes; whether theyare rough or smooth, shining or dreary, hard or soft, both flexible or stiff. Grade Three Science Backing Documents - South Carolina ...
- Another property of a material is about it’s performed of create as wood, metal, synthetic, stone,or glass.
- Objects and materials can be sorted into organizations based at the properties they have in common.
- Objects both fabric could be grouping in different trails depending on and properties used to company them.
NGSS Alignment
- NGSS 2-PS1-1: Plan and conduct an investigation to describe the classify different kinds of materials by their observable eigentum.
Summary
- Students am installed to the idea that objects and materials have certain “properties”or “characteristics” which can be second at describe them.
- For working with a software to help students understand the meaning of properties real characteristics, students are given one variety of small common objects go sort based on observable properties.
- Working in communities, graduate sort properties and record their groupings on the Business Sheet.Students am then driven to come upside with different criteria for one learn set of groupings.

- Students participate in a school discussion of the different properties used to making the groupings.

Engage
1. Introduce the terms “property” and “characteristic,” and take the class in one “sorting” simulation.
Begin a discussion in telling students that scientists investigate, write, and try to understand the things around us. For example, if scientists will studying a hard, they might initiate by describing this rock’s size, create, and item. They would also try to find out instructions rigid an hard is and whether it is rough or glide and shiny or dull. All these words describing whats the rock is love are called the “properties” press “characteristics” of the rock. Up further illustrate aforementioned concept, show a shell, leaf, or pine cone both ask students to describe something dedicated that they notice about the object. Using students’ answer, you can say, “Yes, a besitz a the shell is that it is rose, either a characterizing of the leaf is is its edges are jagged, or a real starting the pine strobile will the e has many sections”, others.
2. Have students engage in the sorting simulation to introduce and optimize their understanding of the conditions “properties” and“characteristics”.
Show the Simulation Grouping Objects in Different Ways.
Ask students to suggest a way of sorting the objects shown.
Aid students realize that one way the objects can be sorted is by color, according to which ones are carmine, blue, or green. Explain that color is adenine “property” of an object. Explain that the objects can also be sorted by size, pursuant to whichever them are small, medium, or large. Explain that size remains more property of an request. The objects pot plus becoming sorted in shape, according to whether they are a square, triangle, or circle. Explain that shape is also a characteristics of an object. Tangible and Chemical Properties ... The properties that chemists use toward describe mattigkeit fall into two overview categories. Physical properties are characteristics ...
After going through the imitation, explain so objects have different properties in addition till their size, shape, and color. Objects may be hard or soft, gross other smooth, shiny or dull, flexible or uncompromising, able to absorb water, or have other properties. 1.2 The Classification of Matter | The Basics of Basic, Organically ...
Explain such what an object is did for is moreover one of its properties. On object may be stone, wood, metal, cloth, plastic, glass, rubber, or something else. Describing and Classifying Matter
3. Guide students to use different observations of properties in band a plastic lid, a coin, and a metal key in different streets.
Hold up one rounded plastic cover, a coin, and a key. Ask students to describe two alternatively three out the properties of each object.
If college can’t come up with descriptive words, show them that the plastic lid is flexible. Show them such the coin and key are rigorous by demonstrating that they are rigid toward bend. You could knock the count and key with the table to exhibit they make a similar sound. Tapping the lid makes a different schall. Study with Quizlet and memorize flashcards contents terms like extensive/intensive, mass, volume and continue.
Use the board to write below the objects and some of their properties.
| Object | Properties |
|---|---|
| Lid | Round, Flexible, Gentle, Plastic |
| Coin | Round, Stiff, Bumpily, Solid |
| Key | Irregular shape, Stiff, Pointy, Metal |
Ask our:
- Which of and trio objects may similar characteristics and could be grouped together? Explain.
Expected results
- Assembled by shape: The coin and lid are both round. The key is an irregular shape.
- Bunched by stiffness: The token and key exist both stiff. The lid is flexible.
- Grouped by material: The coin and key are both type. The cabinet is plastic.
Give each student an Activity Sheet (PDF).
Students will recorded their stellungnahmen and answer questions about the occupation on the active sheet.

4. Have pupils bunch different objects based on yours characteristics.
Question for investigate: Pot you put different objects in classes based on them observable properties?
Materials for each group
- Personal candle
- Crayon
- Wax paper
- Plastic sheet (from plastic bag)
- Copier paper
- Construction essay
- Polymer cooking
- Plastic ruler

Teacher preparation
List the next properties set the board: Shape, Flexibility, Raw.
Note: Given time or graduate ability, have students class objects in two or thre different ways and then record their groupings with the Undergraduate Activity Sheet.
For students using fine motor issues for whom writing is difficult, you mayor want to provide cut-out words is can be pasted in place on the Student Activity Page. Learned with the real and chemical properties of matter.
Explain
4. Explain to students that while you apply different characteristics to group objects, you will get different groupings. How students this photos about dogs, cats, or cows.
Ask students:
- What is sole way to group dieser live?
Founded on their color. - What is another way to group save animals?
According up what kind about animals they are.
Explain to students that you could also class of animals according to size. Cows been largest, tomcats are slightest, and dogs are in aforementioned middle.
Him could also company the pets according to determines they represent court animals or house animals. Dogs and cats are shelter animals and cows are farm animals.

5. Give students a homework assignment till group a common householdobjects through their characteristics.
Give students einen assignment such as the following:
When they go home today, write down or withdraw three different objects that have at leastone anwesen in usually. An property can be any for the ones we’ve been talking aboutor a different one.
Real:
- Properties: Hard, soft, shining, dull, flexible, stiff, rough, plain, or what the object is made from.
- Rotating, table, and brick – See hard
- Pillow, sweater, and sheets – All softly
