How to address violence in the news with your kids.
High school and middle school physical science (and math) teachers can use Lab4Physics to help students practically apply concepts in their classes. Have the students use the pre-designed experiments first to help them figure out how to use the tools provided by their devices. Then empower them to design their own investigations.
Math teachers might show four different linear graphs to their students. Then, have students use the speedometer tool to create those same four graphs. By physically moving faster or slower, students will learn what slope actually means.Continue reading Show less
Lab4Physics uses the accelerometer, camera, and microphone already built into smartphones (and tablets) to gather data for physics experiments. Some of the topics include Movement, Waves, and Force and Energy. Students can select a pre-designed experiment to puzzle through questions such as “How many people does it take to move a school bus?” Or, students can use tools such as the sonometer or speedometer to design and conduct their own experiments. Either way, students will need inexpensive materials such as string, tape, and pebbles to conduct the investigations. Each student group will use the app on a device to gather data in real time.
The Teacher's Resources site is a portal where you can find tips from other teachers, letter templates to send home to parents, tutorial videos, and other helpful support. Along with the lesson plans provided on the site, teachers can create their own experiments.
Lab4Physics is an incredibly low-cost way for students to design and conduct physical science investigations. Equipping a physics lab with sensor tools and software can cost districts over $5,000. This app accomplishes many of the same things using the smartphones that students already have in their pockets.
An extensive teacher resource website provides activities aligned to the Next Generation of Science Standards. Whether spinning like a tornado using the accelerometer or transforming their phones into pendulums, students are gathering real-time data themselves. After using tools such as the accelerometer, students can manipulate the way the data is represented, looking at acceleration, velocity, or position over time. This tool embodies a shift in science where students are the ones actually doing the science and figuring out the best way to make sense of and share their results.
Key Standards Supported
Linear, Quadratic, And Exponential Models
Interpret the parameters in a linear or exponential function in terms of a context.
Key Standards Supported
Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.
Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative position of particles (objects).
Motion and Stability: Forces and Interactions
Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
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.
Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects.
Waves and Their Applications in Technologies for Information Transfer
Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
