Students work as physicists to understand centripetal acceleration concepts. They also learn about a good robot design and the accelerometer sensor. They also learn about the relationship between centripetal acceleration and centripetal force governed by the radius between the motor and accelerometer and the amount of mass at the end of the robot's arm. Students graph and analyze data collected from an accelerometer, and learn to design robots with proper weight distribution across the robot for their robotic arms. Upon using a data logging program, they view their own data collected during the activity. By activity end , students understand how a change in radius or mass can affect the data obtained from the accelerometer through the plots generated from the data logging program. More specifically, students learn about the accuracy and precision of the accelerometer measurements from numerous trials.

Do you need proof that driving is a dangerous activity? More Americans have died in car crashes over the past 100 years than in all the wars the U.S. has ever fought combined. More than 40,000 Americans die each year on the nation's highways, most as the result of high-speed collisions. In this video segment adapted from NOVA, learn how engineers developed the air bag, an important automobile-safety device now found in most cars.
Recommended for: Grades 3-12

Students prepare for the associated activity in which they investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Based on the experimental set-up for the activity, students form hypotheses about the acceleration of the device. Students will investigate how the force on the device changes according to Newton's Second Law. Different types of acceleration, including average, instantaneous and constant acceleration, are introduced. Acceleration and force is described mathematically and in terms of processes and applications.

In the first of two sequential lessons, students create mobile apps that collect data from an Android device's accelerometer and then store that data to a database. This lesson provides practice with MIT's App Inventor software and culminates with students writing their own apps for measuring acceleration. In the second lesson, students are given an app for an Android device, which measures acceleration. They investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Then they use the data to create velocity vs. time graphs and approximate the maximum velocity of the device.

Conceptual Physics 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 unit 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 unit, 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 unit, 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.

Students conduct an experiment to study the acceleration of a mobile Android device. During the experiment, they run an application created with MIT's App Inventor that monitors linear acceleration in one-dimension. Students use an acceleration vs. time equation to construct an approximate velocity vs. time graph. Students will understand the relationship between the object's mass and acceleration and how that relates to the force applied to the object, which is Newton's second law of motion.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

Explore the forces at work in a tug of war or pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

The High School Integrated Conceptual Science Program (ICSP) is a NGSS-aligned curriculum that utilizes the conceptual progressions model for bundling of the NGSS, High School Conceptual Model Course 1 and strategies from Ambitious Science Teaching (AST) to focus on teaching practices needed to engage students in science discourse and learning. Course 1 is the High School Integrated Physics and Chemsitry Course.   The goal of these units is to encourage students to continue in STEM by providing engaging and aligned curriculum. The focus of this year long course is on the first year of high school (freshman).  While the course is designed to be taught as a collection of the units, each unit could be taught as a separate unit in a science course.  A video about the new course shared its unique approach to learning and teaching. Wenatchee School District, one of the participating districts, wanted a way to share the program with the community. https://youtu.be/9AGk19YUi2oCourse 1 of the ICSP development was funded by Northwest Earth and Space Sciences Pipeline (NESSP) which is funded through the NASA Science Mission Directorate and housed with Washington NASA Space Grant Consortium at the University of Washington.

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

Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration. This is done through a Lecture on Newton’s Laws of Motion, a Discovery Activity, a Lecture of Force Diagrams, and a Guided Inquiry Activity. The columation of these resources provide the students with opportunities to explore Newton’s Second Law of Motion and understand the mathematical relationships between Mass, Acceleration, and Force.

Patterns Physics is the initial course in the 3-year high school Patterns Science sequence. Patterns Physics focuses on three-dimensional (3D) learning through culturally responsive, phenomena-based storylines that intertwine the disciplinary core ideas of physics and earth science with the scientific and engineering practices and crosscutting concepts as described in the Next Generation Science Standards (NGSS).

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.

Explore forces and motion as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces. Graphs show forces, energy and work.

In this hands-on activity, students learn about two types of friction static and kinetic and the equation that governs them. They also measure the coefficient of static friction and the coefficient of kinetic friction experimentally.
