From the Atomic Archive - the online companion to the award-winning CD-ROM. This page includes an interactive Shockwave movie which allows visitors to explore the prevalence of global test sites for nuclear weapons from the mid 1940s to the mid 1990s.
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. [1:30]
Check your understanding of how to use the atomic number and the mass number to represent different isotopes. [9:43]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Video tutorial explains the difference between atomic weight and atomic mass in chemistry, and how it compares to the physics definitions of weight and mass. [8:53]

Watch this video lesson introducing the atom, and learn about its unique structure. [3:58]
Help the Mummy build a rollercoaster to entertain the Atoms Family monsters by investigating the concepts of kinetic and potential energy.
This video segment adapted from A Science Odyssey takes a look at the scale of the atom and the tremendous amount of space between the electrons and the nucleus. If all this empty space exists in matter, how can any substance be solid? [1:15]
After your group explores the Arcadia Earth app section titled Keep the Great Lakes GREAT! and are introduced to challenges the amazing Great Lakes face, learners investigate their own use of a precious resource, water. The lesson culminates with learners developing strategies to conserve water and identifying how they can play a part in keeping our Great Lakes Great!
Estimated time required: 1 class period.
Technology required for this lesson: Tablet or Smartphone.

Aurelia will introduce students to biological adaptation using fish as the model organism. Organisms have adaptations that help them survive in their environment, including fish. Fish live in a variety of habitats thus leading to their diversity in body form and shape. To better understand how adaptations are tailored for various environments, students will explore the Pelagic enviroment. Pelagic fish live in the pelagic zone of ocean or lake waters – being neither close to the bottom nor near the shore.
Estimated time required: 1-2 class periods.

Fish live in a variety of habitats thus leading to their diversity in body form and shape. To better understand how adaptations are tailored for various environments, students will explore the freshwater enviroment. Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%.
Estimated time required: 1-2 class periods.

Fish live in a variety of habitats thus leading to their diversity in body form and shape. To better understand how adaptations are tailored for various environments, students will explore the coral reef enviroment. Coral reef fish are fish which live amongst or in close relation to the complex coral ecosystems with tremendous biodiversity.

Noah lives near the Great Barrier Reef. Go explore this diverse habitat with him.
Learn about the different types of igneous rocks and how they are classified.
Learn the process by which metamorphic rocks are created, where they are located, and how they are identified by texture (foliated and non-foliated) and mineral composition.
Basic information about the universe, its origin and composition. Also includes information about galaxies, stars, and the sun.
