Course Summary

Life is a series of complex interactions. The anchor phenomenon for this course, the human body, is no exception. The basis of the human body is the cell. Associations of cells work together to form tissues, which form organs. Organs work together to perform specific functions in organ systems. And finally, the array of organ systems make up a human body.

Middle school students are prepared to explore how organ systems interact to support each and every cell in the body. The guiding question for the course is how do humans live, grow, and respond to their environment? What happens when the body is attacked by an invader or an organ system malfunctions? How do cells get the resources they need to live? How do cells gain access to the energy stored in energy-rich compounds? How do systems support the human organism as it senses and interacts with the environment?

These questions inspire students to find out more, and may spawn a lifetime of learning about their body systems and the environmental factors that affect them. Questions like these have the potential to help students understand and appreciate what may be of highest importance to them, themselves."

"Single-celled archaea that live in incredibly saline pools, an extravagantly feathered bird that courts a mate with song and dance, a fungus that covers over a square mile of forest, nudibranchs that glide along the seafloor, a leopard seal that shoots through Antarctic waters in pursuit of a penguin. Life on Earth is a dizzying array of diversity. Yet all life, no matter the diversity, shares common characteristics. All life is cellular, depending upon cellular processes for survival. And all life shares a genetic organization based on DNA and RNA.

The theory of evolution is the unifying principle that explains both the similarity and diversity of life. Evolution forms the foundation of modern biology and is supported by a vast array of observable evidence. Middle school students are ready to explore the varied lines of evidence, including the fossil record, the similarities between past and present organisms, the genetic principles of inheritance, and how natural selection produces adaptations that lead to changes in species and eventually the creation of new species."

"In this course, some of the concepts students will learn are:

  • The Moon can be observed both day and night.
  • At all times, half of Earth is illuminated (day) and half is dark (night).
  • Daytime and nighttime are the result of Earth's rotation on its axis.
  • The tilt of Earth's axis and Earth's revolution around the Sun results in seasons.
  • Scale is the size relationship between a representation of an object and the object.
  • The Moon shines as a result of reflected light from the Sun. Half of the Moon is always illuminated (except during a lunar eclipse).
  • Craters can be categorized by size and physical characteristics: simple, complex, terraced, ringed (or basin), and flooded.
  • The solar system formed during a sequence of events that started with a nebula.
  • The Moon formed after a massive collision between the forming Earth and a planetesimal about the size of Mars.
  • The distance between solar system objects is enormous.
  • Liquid water is essential for life as we know it.
  • Scientific missions provide data about the composition and environmental conditions on the planets, moons, and other bodies in the solar system.
  • Planetary-system objects move in measurable and predictable patterns.
  • The magnitude and duration of the dip in light intensity during a transit reveals information about the planet."
