1.3 - Matter
The student will investigate and understand that objects are made from materials that can be described by their physical properties.. Key concepts include
a) objects are made of one or more materials with different physical properties and can be used for a variety of purposes;
- make and communicate observations about the physical properties of materials. Bloom's Level: Understand
- classify objects based on physical properties and explain how the objects were classified. Bloom's Level: Analyze / Understand
- recognize that an object may be composed of different materials and these materials have different physical properties. Bloom's Level: Understand
- analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose. Bloom's Level: Analyze
b) when a material is changed in size most physical properties remain the same; and
- compare the physical properties of larger and smaller samples of the same material. Bloom's Level: Understand / Analyze
c) the type and amount of material determine how much light can pass through an object.
- identify uses for different materials based on the amounts of light that passes through. Bloom's Level: Understand / Apply
- with guidance, conduct an investigation to determine how the type and amount of material affects how much light can pass through an object. Bloom's Level: Apply
Different materials may have different physical properties; these properties are used to describe and classify objects.
UNDERSTANDING THE STANDARD
- Objects can be described by their properties.
- Objects are made of o.ne or more materials. These materials can be described by their physical properties.
- Physical properties include (but not limited to): light transfer, texture, weight, length, color, and odor.
- Different properties are suited for different purposes
- Most properties of materials remain the same regardless of their visible size.;
- Physical properties such as how much light passes through a material color, texture odor, ability to dissolve in water, etc. remain the same; however properties such as mass, volume, and length change when the size changes.
- Some materials allow light to pass through them, others allow only some light through, and others block all the light. Students are NOT required to know the terms translucent, transparent, and opaque.
- For materials that allow light to pass through, adding more of that material can change the amount of light that passes through.
What are some physical properties of objects?
How can objects be classified using physical properties?
How can physical properties be used to create new products?
In order to meet this standard, it is expected that students will
- identify and communicate observations about the physical properties of objects.
- classify objects based on their physical properties and explain their classification process.
- recognize that objects may be composed of different materials and the materials each have different physical properties.
- test materials and analyze which materials of have the properties that are best suited for a specific purpose.
- compare the physical properties of larger and smaller samples of the same material.
- identify different uses for different materials based on the amount of light that passes through.
- investigate the question, "How does the type and amount of material affect how much light can pass through an object?"
