Description of Unit

Fifth-grade students will study the physical properties of matter: mass, magnetism, physical state (solid, liquid, or gas), relative density, solubility in water, and the ability to conduct or insulate thermal or electric energy. This task integrates science, English language arts, and social studies. In this project, students will identify the physical properties of various toys. They will determine how these toy properties can be measured, classified, changed, and used. Students will learn about toys that are currently on the market and safety rules and regulations in the toy industry. To complete the task, students will have the opportunity to develop a prototype design, model, or illustration of their own original toy. They will create an advertisement for the original toy that focuses on its physical properties.

This guide links the Toys that Matter unit to the Texas Essential Knowledge and Skills (TEKS) for fifth graders. Toys that Matter is a science unit that allows students to study the physical properties of matter: mass, magnetism, physical state (solid, liquid, or gas), relative density, solubility in water, and the ability to conduct or insulate thermal or electric energy. Students will relate these properties of matter to products found in everyday life by focusing on the specific physical properties of toys. Toys that Matter also has interdisciplinary connections to the English language arts, reading, and social studies disciplines. For example, students will use writing as a tool for learning in research, as described in the English Language Arts and Reading TEKS. They will also learn about the impact of science and technology on society in the United States, as included in the Social Studies TEKS. The following document includes the applicable TEKS and the details of the Toys that Matter unit. The final section of this document presents the applicable Texas College and Career Readiness Standards adopted by the Texas Higher Education Coordinating Board (THECB) on January 24, 2008.

Phase I. Learning Experiences

  1. Students will begin the unit by holding a class discussion on their favorite toys. They will detail the most fun or entertaining features of these toys.
  2. Students will discuss the physical properties of matter (e.g., mass, magnetism, physical state, relative density, solubility in water, the ability to conduct or insulate thermal or electric energy) and give an example of each property. They will review the differences between the three states of matter, along with what makes something a solid, liquid, or gas.

    Students will form small groups and examine a baggie full of putty, oobleck (https://www.livescience.com/21536-oobleck-recipe.html), or any other gooey substance. Students will work together to describe its observable physical properties.
    • What is its coloration?
    • Does it have an odor?
    • Can it hold its shape or does it change to the shape of its container?
    • Does it change its state when heated or cooled?
    • Is it soluble or buoyant in water?
    • Does it conduct electricity or is it an insulator?
    Student groups will describe the item’s physical properties of matter and list them on a chart. The groups will create the charts on pieces of butcher paper, listing the physical properties at the top and their descriptions in corresponding columns below.
  3. Each student group will receive a specific toy to study. It is important to provide groups with a variety of toys (e.g., toys that use batteries, have magnetic pieces, float, are heavy or light, have interchangeable parts). Students will observe their toy and identify its physical properties of matter. Questions for the groups to consider include the following:
    • What state of matter is the toy?
    • Does it contain or use any other state of matter?
    • Does it use electricity or magnetism in any way?
    • Would it float or dissolve in water?
    • What is its mass?
    Student groups will record as many observations as possible to share with the other groups. They will share the properties of their toy with the class orally, demonstrate the uses of the toy, and show if it can be changed or modified.
  4. Students will research popular toys that are currently on the market. They will need to identify what it is about the toy that consumers like. Some questions to consider as they research popular toys include the following:
    • What does the toy do?
    • Is there motion or action involved that requires a source of electricity?
    • Is it magnetic?
    • Does it dissolve?
    • Does it float in water?
    • What is the current supply and demand for this toy?
    Students can use advertisements, catalogues, or the Internet to search for popular toys and their descriptions and pictures. They will select one toy and record the toy’s details, features, and physical properties of matter in a descriptive and informative paragraph.
  5. Students will research and identify how toys are classified or grouped in stores (brick-and-mortar and online). They should consider the following questions in their research:
    • How are toys displayed? By gender or type of toy?
    • Are toys classified by their physical properties?
    • How are the toys organized?
    • What types of toys are placed together on the store shelves or aisles?
    • Why are they placed together?
    • How are they labeled and grouped in online stores?
  6. Students will explore the relationship between advertising and toys. Students need to identify the correlation between the most popular toys and their successful advertisement campaigns. The teacher will hold a discussion on the strategies used by popular toy companies to get the attention of children (or other target audiences). Students should think about the following questions during their discussion:
    • How are toys advertised?
    • How are the physical properties of the toys highlighted in the commercials or ads?
    • Where and when might be the best possible place or time to advertise toys?
    • How do advertisements successfully target a specific audience?
  7. Students will investigate safety rules and regulations in the toy industry. They will research the safety standards for various toys as they relate to the physical properties of heat or electrical conduction. Students will look for standards that must be put into place for toys with batteries or magnets. They will consider how consumers can be made aware of the dangers of possible injury caused by electricity or magnetism. Suggested resources to guide their research include the following:

Phase II. Independent Research

A. Research process

  1. Selecting a topic. Each student will select at least three physical properties of matter that he or she would like include in an original toy design. The student will brainstorm an idea or design for an original toy, name the toy, and write a descriptive paragraph about it. This will include how the toy will work, its physical properties, and a general illustration of the toy.
  2. Asking guiding questions. Once each student has designed a toy, he or she should consider the following guiding questions:
    1. What age group will your toy target?
    2. What safety precautions will you take in designing this toy for the appropriate age group?
    3. What are the physical properties of your toy?
      1. Is it magnetic or will it conduct heat or electricity?
      2. Does it need electricity as a source of energy?
      3. Is it soluble or will it float in water?
      4. What is its mass or size?
    4. How will the toy be classified or used?
    5. What category of toy does it fit into?
    6. Can the toy change? Do its physical properties change?
    7. What will the toy be made of? Can you make a prototype of it?
    8. What resources will you need?

      While these are general examples, the student’s questions should be specific to the toy design and its properties of matter. The questions should lead to research-based opinions.
  3. Creating a research proposal. Each student will determine what sources (primary and secondary) he or she will use to collect information. This information will support the student in the creation of an original toy. He or she will create a rough-draft sketch or design for his or her proposal.
  4. Conducting research. The student will research the process of creating a unique toy. Each student will design and illustrate his or her toy, demonstrating or labeling three or more physical properties of matter. The toy can be made up of old toys or parts of toys that have been altered or changed. It is important for the student to draw a design, labeling the different parts of the toy and its properties, prior to actually making the prototype. Parent or teacher supervision will be needed when adding the electrical or heating components of the toy.
  5. Drawing conclusions. The student should consider the following questions:
    1. What materials will the toy require? Are these materials readily available?
    2. Were the physical properties of matter used in the toy development and design
    3. Were there three or more observable properties?
    4. Were the appropriate safety rules and regulations followed?
    5. For what age group is the toy most appropriate?
    6. How is the toy classified?
    7. Can it be changed or adapted in any way to improve its design?
    8. What makes this toy unique or different from other toys?
    9. Would it be possible to manufacture this toy in the future?

B. The product

Each student will exhibit what he or she has learned through one of the following products:

  1. An advertisement for a magazine, newspaper, catalogue, or online website that features the physical properties of matter of the designed toy. Each ad should include the toy name, a description, its uses and functions, and its physical properties. The ad should identify the toy’s safety features and targeted age group.
  2. A commercial (online or television) to market the toy. The commercial must include a slogan or jingle relating the key physical properties of the toy. The student will use the prototype as a key feature in the commercial and target a specific core audience.
  3. A store display featuring the toy, its physical properties of matter, and functions/uses. The classroom will be turned into a toy store for the day, and each student must decide where his or her toy display would best fit according to its classification. Each student will design and build an interactive store display and take part in “selling” his or her toy to other classmates or students. This display may also include an ad, brochure, or commercial.

C. Communication

The student will present to the class what he or she has learned about the properties of matter in relation to the toy that he or she designed and created. This will be a multimedia presentation that utilizes research, sketches, designs, charts, graphs, etc. The student should describe each property of matter that is modeled or used in his or her toy. He or she will include an ad/brochure, video commercial, or store display that clearly communicates the name of the toy, a description, its uses and functions, and its physical properties. The audience will be given time for a question and answer session.

D. A completed project consists of:

  1. A research proposal
  2. An original toy design, description, and labeled illustration
  3. A product/toy prototype design with ad/brochure, commercial, or store display
  4. A multimedia presentation (e.g., research, sketches, designs, charts, graphs)
