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.
Force and Motion: Newton's First Law
- Recognize and give examples of forces.
- Recognize and give examples of balanced and unbalanced forces.
- Equate the term “unbalanced force” with “a net force that does not equal zero.”
- Apply, in an informal way, Newton’s first law.
- Explain the role of the force of friction in determining how well Newton’s first law seems to apply or not apply to a given physical situation.
- Explain the reasoning Galileo used to justify the second part of Newton’s first law.
- Explain how the force of friction applies to the second part of Newton’s first law.
- Recognize the concept of inertia (as opposed to a force, momentum, etc.).
- Recognize that an object at rest may have forces acting on it.
- Distinguish between “impulse” and “sustained” forces (and recognize both).
- Recognize that objects do not have internal forces that keep them moving.
