In this unit, students explore how communication systems transmit information from one person or place to another. In this lesson, students use what they know about the science phenomena of electromagnets and magnetic fields to design a speaker, a common decoding device in many audio technologies. This page highlights key components of this lesson.
In this unit, students focus on the Earth-Sun-moon system to explore how gravity pulls objects including satellites into orbit. In this lesson, students engineer an insulating solution for a prototype satellite that minimizes the amount of thermal energy transferred into or out of it.
In this unit, students build on their scientific knowledge about matter, energy, and heat transfer to explore the phenomena of weather and climate. They investigate how the sun powers the global water cycle, which in turn has very local impacts that affect the phenomena of regional climates around the world. They then use that knowledge to figure out and design a technology that solves the problem of drought-related water shortages.
In this unit, students explore forest ecosystems, studying the science phenomena of interactions between living things and the environment. In this lesson, students build on their understanding of how energy affects the growth of organisms by exploring the phenomena of forest food webs, and analyzing how the phenomena of drought can have a ripple effect through the ecosystem. This page showcases all components of this lesson.
In this unit, students explore how engineers and architects design structures that help human populations survive and thrive in their environment. Students take on the challenges of civil engineers as they design different types of bridges to discover a design that can carry the maximum load. This page highlights the components of this lesson.
In this unit, students apply what they have previously learned about forces, motion, and matter to the solar system, focusing on the phenomena of gravity’s role in the universe. In this lesson, students engineer a solution to collisions between moving objects in space. This page is a high-level extract of this lesson.
In this unit, students evaluate how Earth is heated unevenly by investigating how the angle that the sun’s rays hit Earth affects temperatures at different locations. In this lesson, students use their scientific knowledge of phenomena related to global warming and climate to engineer a model greenhouse that reaches a specific temperature. This pages provides a snapshot of this lesson.
