In this interactive activity, learners explore factors that cause atoms to form (or break) bonds with each other. The first simulation depicts a box containing 12 identical atoms. Using a slider to add heat, students can see the influence of temperature on formation of diatomic bonds. Simulations #2 and #3 introduce learners to reactions involving two types of atoms. Which atom forms a diatomic molecule more easily, and why? The activity concludes as students explore paired atoms (molecules). In this simulation they compare the amount of energy needed to break the molecular bonds to the energy needed to form the bonds.

In this interactive activity, learners build computer models of atoms by adding or removing electrons, protons, and neutrons. It presents the orbital model of an atom: a nucleus consisting of protons and neutrons with electrons surrounding it in regions of high probability called orbitals. Guided tasks are provided, such as constructing a lithium atom and a carbon-12 atom in the fewest possible steps. The activity concludes with a model for building a charged hydrogen atom (an ion). Within each task, students take snapshots of their work product and answer probative questions.

In this lesson, students will explain CRaTER's purpose and how it works. They will also design (using paper and pencil) a cosmic ray detector to answer their own questions. CRaTER's purpose is to identify safe landing sites for future human missions to the moon; discover potential resources on the Moon; and characterize the radiation environment of the Moon. The lesson includes background information for the teacher, questions, and information about student preconceptions. This is lesson 4 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation."

This book on Cybersecurity is written for beginners. No college degree is required. Cybersecurity covers a broad spectrum of topics. This book intends to ease the initial learning curve using associable analogies in normal life and graphical and guided exercises. Completing the Cybersecurity study in this book can be accomplished in a self-paced learning manner outside of a classroom.
It is hoped that self-paced learning and/or the teaching of this book at various institutions will open the doors to a broader audience in their career development towards the job-rich cybersecurity industry. Further, it is hoped that by demystifying cybersecurity, people will build up their interests and confidence in transitioning into the cybersecurity industries from whatever field they are working in today.
