  • Big Ideas
    A technological world requires that humans develop capabilities to solve technological challenges and improve products for the way we live.
    Each area of technology has a set of characteristics that separates it from others; however, many areas overlap in order to meet human needs and wants.
    Technological design is a creative process that anyone can do which may result in new inventions and innovations.
    Technological literacy is the ability to use, assess and manage technology around us.
    Technology is created, used and modified by humans.
  • Concepts
    A technological design & problem solving process changes ideas into a final product or system.
    Bio-related technologies are the processes of using biological mater to make or modify products.
    Bio-related technologies are the processes of using biological organisms to make or modify products.
    Communication is the process of composing, sending, and receiving messages through technology.
    Communication is the process of composing, sending, and receiving messages using technological devices.
    Construction is the process of turning materials into useful structures.
    Construction is the process of turning raw materials into useful structures.
    Decisions about the use of products and systems can result in expected and unexpected consequences.
    Energy and power technologies are the processes of converting energy sources into useful power.
    Energy and power technologies use processes to convert energy into power.
    Innovation is the process of improving an existing product, process, or system.
    Invention is a process of creating new products, processes, or systems.
    Inventions and innovations must be carefully assessed by individuals and society.
    Manufacturing is the process of turning materials into useful products.
    Manufacturing is the process of turning raw materials into useful products.
    People select, create, and use science and technology and are limited by constraints (e.g. social and physical).
    People select, create, and use technology.
    Safety is one of the most important concerns for all technological development and use.
    Science and technology are interconnected.
    Technological design & problem solving follows many steps.
    Technological design & problem solving includes clearly communicated solutions.

Rationale

How does melting a molecular crystal affect its alignment?

Molecular crystals are formed by one or more kinds of molecules tiled up in microscopic space in regular patterns.

A common example is solid carbon dioxide or dry ice that is often used to pack and keep ice cream cold.

Can you think of any other common examples of molecular cystals? Hint: Another example of a molecular crystal hangs from roofs during winter.

Description

This activity uses a computer simulation demonstrating molecular models to explore how melting molecular crystals affects their structure.
