This interactive activity helps learners visualize the role of electrons in the formation of ionic and covalent chemical bonds. Students explore different types of chemical bonds by first viewing a single hydrogen atom in an electric field model. Next, students use sliders to change the electronegativity between two atoms -- a model to help them understand why some atoms are attracted. Finally, students experiment in making their own models: non-polar covalent, polar covalent, and ionic bonds.

This concept-building activity contains a set of sequenced simulations for investigating how atoms can be excited to give off radiation (photons). Students explore 3-dimensional models to learn about the nature of photons as "wave packets" of light, how photons are emitted, and the connection between an atom's electron configuration and how it absorbs light. Registered users are able to use free data capture tools to take snapshots, drag thumbnails, and submit responses.

This lesson on fingerprinting takes a unique approach to a standard topic in Forensic Science. While students will learn the basics of fingerprinting, how to lift a print and learn unique characteristics of fingerprints, they will become aware of the flaws of fingerprinting. By investigating the case of the Madrid Spain Bombing students will discover a match is not always accurate.
The ocean's resources are slowly being depleted. This curriculum examines the issue of overfishing and its impact on both the environment and human life. In developing sustainable solutions, the students address the driving question: "How can we as youth, sustain the future of the world's ocean through our actions today?"
Using inquiry-focused reading, students will explore an anchor text and supporting resources to investigate the principles of transfer of heat energy with applications of the concept to solve real world problems.
Intermolecular attractions are responsible for everything from the temperatures at which substances boil to the power of your immune system in recognizing pathogens and the climbing ability of geckos! Feel the strength of London dispersion and dipole-dipole attractions, explore how intermolecular attractions affect boiling point and solubility, and investigate the special role of hydrogen bonds in DNA. Finally, design your own antibody based on intermolecular attractions.
Learners use the internet to collect information for school or daily life. Search engines can produce an excessive number of potential sources, even when filtering the search. This lesson will teach the adult learner a stepwise approach to defining key words, specifying criteria, and evaluating the appropriateness of sources. The learner will develop a customized checklist for the search and demonstrate the acquired knowledge of selecting appropriate sources.
The lessons in this unit were developed by teachers at Souhegan High School for junior/senior level Physics classes, to be taught during the first trimester of the 2016-17 school year. It includes 5-10 lessons that culminate in students demonstrating their ability to find meaning in complex text and incorporate key ideas of modern physics by completing the final creative writing project.
Modern physics is a very broad topic. We will be focusing on three of the main pillars of modern physics — special relativity, general relativity, and quantum theory. The goal of the unit it to have students use the concepts of modern physics accurately in a creative way and increase their willingness and confidence to learn more about the subjects beyond high school. Modern physics is intimidating to the general public. We hope to spark students interest and have students realize that they can make sense out of the counter intuitive model of reality.
Each topic will be broken into several phases of understanding:
Limitations of classical physics
Key principle that led to modern physics
Models for describing modern physics
Predictions and experiments that support and provide evidence for modern physics theories
The students will explore the phases by using inquiry-based reading. They will explore an anchor text for meaning while looking for where it addresses the four phases above. Students will then perform additional research and apply what they have learned in class to create their final project.
Unit covering ethics for interpreters and translators.
