In this interactive activity from ChemThink, take a closer look at atomic structure, properties, and behaviors.
This video/animation asks the question So if the same molecules are in the solid, liquid, and vapor forms of water, why are their properties so different? The properties of a material are affected not just by the kinds of atom in it, but also by how they are arranged, and how free they are to move around. Forms of carbon are introduced, from graphite to buckyballs.
In this hands-on OLogy activity, kids learn about matter by building their own models of carbon out of pipe cleaners, wire, and clay. The activity begins with a kid-friendly introduction to matter, elements, and atoms. The illustrated, step-by-step directions show kids how to use the information about carbon on the Periodic Table to create a mobile that shows the element's basic structure. A PDF version of the Periodic Table, along with a kid-friendly overview of how to read it, is also included.
In this project you will investigate many of the theories that explained the composition of the atom.
How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!
Dr. Chris Muhlstein explains that the arrangement of atoms in a material determines the properties. He drops an iPod to illustrate how the arrangement of atoms can protect it from damage; he narrates footage of the collapse of the Tacoma Narrows Bridge in the 1940s to show how the deformation of materials can cause the collapse of a structure.
The Biology course is a first-year course in biology at the high school level and involves the scientific study of living organisms. The course considers the interactions among the vast number of organisms that inhabit planet Earth. It presents the basic form and function of these organisms, from cells to organ systems, from simple viruses to complex humans. It delves into interactions between organisms, and between an organism and its environment. It also looks into how biotechnology is used to improve our health and daily lives.
- Understand the form and function of microorganisms
- Understand the form and function of plants
- Understand the form and function of animals
- Understand the workings of human biological systems
- Understand biology as it relates to the Earth's environment
Starting from atoms, see how many molecules you can build. Collect your molecules and see them in 3D!
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
This booklet describes the interstellar medium and the local bubble that is being studied by NASA-s CHIPS satellite. It contains review questions and problems for students, plus two activities to help to understand some of the concepts discussed.
This interactive activity developed for Teachers' Domain demonstrates how attractive forces between atoms create chemical bonds, resulting in the formation of molecules and compounds.

This issue of @Concord features five ready-to-use “Lessons” that illustrate how interactive models and tools can fit into real classrooms today. Each of these lessons addresses important content that can be found in all the standards and frameworks, and does it by giving students tools with which to explore and interact. The lessons illustrate how sophisticated math and science content can be taught earlier and how generative the resulting understanding can be.
