Product Detail: Science Object

Description

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the third of four Science Objects in the Force and Motion SciPack. It provides a conceptual and real-world understanding of Newton’s Second Law of Motion. An object’s change in motion is proportional to the net force applied to the object and inversely proportional to the mass of the object (being the measure of its inertia). The magnitude of the change in motion can be calculated using the relationship F = ma, which is independent of the nature of the force acting on the object.

Ideas For Use

Science Objects are two hour learning experiences teachers can use to enhance their understanding of a particular scientific concept. Teachers can access any topic “on demand” from the Internet. Topics are based on the science literacy goals in the national standards (NSES, Science for All Americans, Benchmarks, and the Atlas of Scientific Literacy) and tied to state standards.

Each Science Object provides an understanding of the science content by providing a structured set of learning experiences through simulations and practice assessments. Science Objects challenge teachers to explore and explain real world phenomena and are founded on the principle that learners must be challenged with a problem, observation, data, etc., in order to develop scientific understanding. Science Objects utilize the five phases of inquiry-based learning: Engage, Explore, Explain, Elaborate, and Evaluate.

Learning Outcomes:

Force and Motion: Newton's Second Law

• Understand that the “F” in F = ma stands for the net force acting on an object, “m” stands for the mass of the object, and “a” stands for the resulting acceleration of the object.
• Demonstrate the cause-effect relationship associated with Newton’s Second Law—that net forces cause accelerations and not the other way around.
• Know that a net force was applied if an acceleration is observed, and, if the application of a net force is observed, the result will be an acceleration.
• State and apply Newton’s second law.
• Distinguish between the role of “F” and the role of “m” in Newton’s second law.
• Recognize that an object can apply a force to another object, but an object cannot carry a force with it.
• Use and interpret ratios and proportions, such as through appropriate use of the phrases “for each,” “per”,” or “for every."
