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
- Explain how the number of protons in the nucleus determines an atom's electron configuration and defines it as a particular element.
- Predict how atoms will interact (with other atoms) based on their electron configuration, particularly their outermost electrons.
- Explain how neutrons affect the mass and stability of the nucleus and atoms’ interactions with each other.
- Explain processes of radioactive decay, including the role of nuclear stability and the emitted particles and radiation.
- Compare the decay of an individual nucleus with the rate of decay of a large group of identical nuclei.
- Explain the process of estimating the age of substances by using the decay rate of radioactive isotopes.
