This detailed chemistry lesson from the U.S. Department of Energy focuses on transforming vegetable oil into biodiesel through a process of transesterification. The process described offers a good model for many chemical reaction processes that are used to produce a viable product.

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also learn how to communicate what happens during a chemical reaction by writing the ratios of reactants and products, known as stoichiometry.

Conceptual Chemistry is a year-long course based on CK-12 OER instructional material and supplemented with limited commercially-available materials. The course is project-based, argument-driven inquiry. Each quarter begins with presentation of an intriguing phenomenon, followed by an essential question about the phenomenon, and a project centered on answering that essential question. Throughout the quarter, students conduct research and investigations to answer portions of the question. Each unit has a student "Task" at the end that serves as an assessment of the unit's concepts. At the end of each quarter, students assemble all of the unit tasks and synthesize a personal final project that answers the essential question in a personal context chosen by the student.

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.

The Integrated Conceptual Science Program Course 1 Integrated Physics and Chemistry is a three dimensional course based on the Conceptual Progression Model of the Next Generation Science Standards. It is designed to be used as part of a three course program that addresses all high school science performance expectations. Course 1 is designed for ninth grade students.
This resource includes the teacher materials, supporting documents, and short videos to support teachers in using the materials.
The Courses were designed using the Ambitious Science Teaching (AST) framework. It is strongly encouraged that before using these materials that you be familiar with AST. We suggest that you watch the AST Overview short video found here: https://datapuzzles.org/ambitious-science-teaching and explore this Google Slide deck that contains many resources designed to further your understanding of AST: https://docs.google.com/presentation/d/1WOUVmlm636_7i2l0GYa9JkX1TCK3NMdySfpxKN7IM7A/edit?usp=sharing

Take a breath — where does the oxygen you inhaled come from? In our changing world, will we always have enough oxygen? What is in water that supports life? What is known? How do we know what we know about our vast oceans? These are just a few of the driving questions explored in this interactive STEAM high school curriculum module.

Students in marine science, environmental science, physics, chemistry, biology, integrated science, biotechnology and/or STEAM courses can use this curriculum module in order to use real-world, big data to investigate how our “invisible forest” influences ocean and Earth systems. Students build an art project to represent their new understanding and share this with the broader community.

This 4-week set of lessons is based on the oceanographic research of Dr. Anne Thompson of Portland State University in Oregon, which focuses on the abundant ocean phytoplankton Prochlorococcus. These interdisciplinary STEAM lessons were inspired by Dr. Thompson’s lab and fieldwork as well as many beautiful visualizations of Prochlorococcus, the ocean, and Earth. Students learn about the impact and importance of Prochlorococcus as the smallest and most abundant photosynthetic organism on our planet. Through the lessons, students act as both scientists and artists as they explore where breathable oxygen comes from and consider how to communicate the importance of tiny cells to human survival.

This module is written as a phenomenon-based, Next Generation Science Standards (NGSS) three-dimensional learning unit. Each of the lessons below also has an integrated, optional Project-Based Learning component that guides students as they complete the PBL process. Students learn to model a system and also design and evaluate questions to investigate phenomena. Students ultimately learn what is in a drop of ocean water and showcase how their drop contributes to our health and the stability and dynamics of global systems.

The students will be introduced to a historical account of global climate change and the human events that may have impacted those changes. Fire has been used by humans throughout history to modify their environment, particularly forests, for human benefit. Over time, the management of forests has changed and the result is an increase in catastrophic wildfires. This storyline explores the use of fire as a forest management tool to improve the health of forests thereby decreasing the incidence of catastrophic fires and the role fire plays in climate change. 

Se presentará a los estudiantes un relato histórico del cambio climático global y las acciones humanas que pueden haber afectado esos cambios. El fuego ha sido utilizado por los seres humanos a lo largo de la historia para modificar su entorno, en particular los bosques, en beneficio de los seres humanos. Con el tiempo, el manejo de los bosques ha cambiado y el resultado es un aumento de incendios forestales catastrófico. Este caso explora el uso del fuego como una herramienta de manejo forestal para mejorar la salud de los bosques, disminuyendo así la incidencia de incendios catastróficos y el papel que juega el fuego en el cambio climático.

Patterns Chemistry is an instructional resource for a year-long high school introductory chemistry course. It meets many of the physical science standards from the Next Generation Science Standards, as well as some earth science standards.

The Patterns High School Science Sequence (https://hsscience4all.org/) is a three year course pathway and curriculum aligned to the Next Generation Science Standards (NGSS).

Each course utilizes:
- Common instructional strategies
- Real world phenomena
- Design challenges to engage students and support their learning.
