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.

Students investigate the property dependence between concentrations and boiling point. In section 1, students first investigate the boiling point of various liquid solutions. In section 2, they analyze data collected by the entire class to generate two boiling point curves, one for salt solutions and one for sugar solutions. Finally, in section 3, students use the data they have analyzed to determine how to create a solution that has a particular boiling point and is a cost-effective design.

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 activity, students study gas laws at a molecular level. They vary the volume of a container at constant temperature to see how pressure changes (Boyle's Law), change the temperature of a container at constant pressure to see how the volume changes with temperature (Charles’s Law), and experiment with heating a gas in a closed container to discover how pressure changes with temperature (Gay Lussac's Law). They also discover the relationship between the number of gas molecules and gas volume (Avogadro's Law). Finally, students use their knowledge of gas laws to model a heated soda can collapsing as it is plunged into ice water.

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.
The Integrated Conceptual Science Program Course 1 Integrated Physics and Chemistry is …
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

Our Patterns Chemistry development team of teacher leaders has been working hard through the spring and summer of 2020 to develop distance learning versions of the Patterns Chemistry units. Between March and May they released the below Distance Learning versions of units 4, 5 and 6, as well as paper packets that can be printed for students who do not have access to technology at home. Below are the distance learning version of units 1 and unit 2. The distance learning units can be used in either a fully online or hybrid school model. A Distance Learning version of Unit 3 will be released by the end of September. For schools reopening fully in person, scroll down to see the original Patterns Chemistry unit plans.

Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.
