2 Vehicles and their propulsion systems are designed by analyzing the forces that act on the vehicle. For example, the designs of propellers and jet engines are based on the aerodynamics of airplanes.
Nature of Science:
1 Recognize that our current understanding of forces has developed over centuries of studies by many scientists, and that we will continue to refine our understanding of forces through continued scientific investigations and advances in data collection.
2 Find, evaluate, and select appropriate information from reference books, journals, magazines, online references, and databases to answer scientific questions about motion and acceleration.
2 There are different forms of energy, and those forms of energy can be changed from one form to another – but total energy is conserved
1 Which forms of energy can be directly observed, and which forms of energy must be inferred?
1 Share experimental data, and respectfully discuss conflicting results.
2 Recognize and describe the ethical traditions of science: value peer review; truthful reporting of methods and outcomes; making work public; and sharing a lens of professional skepticism when reviewing the work of others.
3 Use tools to gather, view, analyze, and report results for scientific investigations designed to answer questions about energy transformations.
2 Understand that scientists work from the assumption that the universe is a single system in which the basic rules are the same everywhere. For example, the speed of light in a vacuum is constant across space and time.
3 Select and use technology tools to gather, view, analyze, and report results for scientific investigations about the characteristics and properties of waves.
2 Life Science
1 Human activities can deliberately or inadvertently alter ecosystems and their resiliency
1 Do humans have a unique responsibility to the ecosystems in which they live?
1 Critically evaluate scientific claims in popular media and peer generated explanations regarding interactions in ecosystems, and determine if the evidence presented is appropriate and sufficient to support the claims.
2 Organisms reproduce and transmit genetic information (genes) to offspring, which influences individuals' traits in the next generation
2 How does investigating characteristics of the various bodies in the solar system provide clues to Earth's origin and evolution?
3 Why do objects such as satellites, Moons and planets stay in orbit?
4 How is the life cycle of a star such as the Sun similar to the cycle of life on Earth?
Relevance and Application:
1 Various technological methods and equipment such as telescopes are used to investigate far-away objects in the solar system and beyond.
2 By representing galaxies and solar systems, planetariums allow people to simulate the experience of outer space.
Nature of Science:
1 Understand that scientists work from the assumption that the universe is a single system in which the basic rules are the same everywhere – that planets follow the same rules about forces as other objects.
2 Recognize that our current understanding of the solar system has developed over centuries of studies by many scientists, and that through continued scientific investigations and advances in data collection, we will continue to refine our understanding of the solar system.
4 The relative positions and motions of Earth, Moon, and Sun can be used to explain observable effects such as seasons, eclipses, and Moon phases
1 Why do we observe changes in the relative positions of Earth, Moon, and Sun from Earth over time?
