How the first atomic bomb was created (and used)

# data[].attributes.attachment_link.readable_text
Description: The Manhattan Project was a massive research and development project that included scientists, engineers and the army to create the first nuclear weapon. It required the creation of a massive industrial complex across the country that spent over $2 billion to create bombs that were later used against Japan. Most of the cost of the project went into creating fissile material (material capable of sustaining a nuclear fission chain reaction). This project can be used as an anchoring phenomenon in a unit on nuclear physics and the processes of fission, fusion, and radioactive decay.

Description: Conductivity is an excellent way to classify material by their observable properties. Conducting material (e.g. metal), non-conducting material (e.g. plastic), and semi-conducting material (e.g. graphite) should all be used. A simple circuit with a lightbulb is used to determine the conductivity of different materials. These properties can be used to determine if a chemical change has occurred by testing before and after substances have been mixed. These properties can also be used in the design of an engineering solution.

Complete storyline around bonding, types of reactions, and energy

# data[].attributes.attachment_link.readable_text
What students figure out:

By the end of the unit, students develop ideas about chemical reactions, structures and properties of matter, and the relationship between energy and forces. These ideas include:

A stable molecule has less energy than the same set of atoms separated; one must at least provide this energy to take the molecules apart.

When two objects interacting through a field change relative position, the energy stored in the field is changed.

Whether or not energy is stored or released in a chemical process, can be understood in terms of the collisions of molecules and rearrangements of atoms into new molecules, with consequent changes in the sum of all bond energies in the set of molecules that are matched by changes in kinetic energy.

Chemical reaction of road salt and baking soda shows an exothermic reaction and a change in pH

# data[].attributes.attachment_link.readable_text
Description: This video shows a chemical reaction of sodium bicarbonate (baking soda), calcium chloride (road salt), and an indicator phenol red. The chemicals react to form calcium carbonate, sodium chloride, and carbon dioxide gas. This changes the pH inside the bag resulting in a color change in the phenol red. As much air as possible should be removed from the bag as possible to show the production of the gas. This could be used as an example of chemical reaction that releases energy (exothermic). Since the bag is sealed it could be massed before and after to show the conservation of mass (atoms). This phenomenon was submitted by Brian Babulic.

Description: Elephant toothpaste is a dramatic chemistry demonstration that involves the decomposition of concentrated hydrogen peroxide (H2O2) into water and oxygen. Potassium iodide is used as a catalyst to speed up the reaction. Soap is added to trap the escaping oxygen gas and food coloring is often added to the experiment. This phenomenon can be using in elementary science classes to illustrate non-reversible reactions and can be studied in more detail in middle and high school.

Development

Denver Public Schools teachers, working with a team of researchers from the University of Colorado Boulder and Northwestern University, designed five units, which address common high school physical science performance expectations in the NGSS for high school Chemistry.

Storylines

The units are organized around coherent storylines, in which students ask and investigate questions related to an anchoring phenomenon or design challenge. Students use science and engineering practices to figure out Disciplinary Core Ideas (DCI) and crosscutting concepts needed to make sense of and explain the phenomena or solve the problem presented in the challenge.

Phenomena

The phenomena that students work together to explain in chemistry are what to search for in looking for life on other planets (Search for Life), the potential of hydrogen (Fuels Unit) and nuclear energy (Nuclear Unit) as a greener fuel, and why oysters are dying at high rates (Oysters). Each has been chosen with input from thousands of students in a national survey as to what would be interesting and engaging to students like them.

Science and Engineering Practices

Students engage with all eight science and engineering practices, becoming more proficient in learning when and how to use the practices. Lessons engage students in practices where they investigate, make sense of phenomena and problems, construct and critique models, and develop explanations and arguments. The units are designed to support students in becoming more sophisticated in their use of practices over the school year. Design challenges help students integrate knowledge across units; over time, students are expected to take more and more responsibility in problem solving within them.

Embedded Assessments

There are multiple assessments embedded in the materials that can be used for formative and summative purposes. These include exit tickets with multiple-choice questions that assess both student experience and understanding, student models of phenomena, and 3D transfer tasks in which students apply what they have learned to a new phenomenon.
