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
Describe the overall process by which chlorophyll-containing organisms utilize energy from the sun in synthesizing glucose and oxygen.
- Trace the path of a carbon atom that is part of a carbon dioxide molecule in the air through the processes that could lead to it becoming part of a glucose molecule synthesized by a plant. Include other reactants and products that are a part of the process.
- Trace the transformation of the energy from the sun as a living plant uses it to synthesize glucose.
- Explain why complex carbon-based molecules (for example, glucose and lipids) have a higher-energy content than the carbon dioxide and water molecules from which they are synthesized.
- Explain how plants or other photosynthesizing organisms use the products of photosynthesis.
