When we look at the night sky, we see stars and the nearby planets of our own solar system. Many of those stars are actually distant galaxies and glowing clouds of dust and gases called nebulae. The universe is an immense space with distances measured in light years. The more we learn about the universe beyond our solar system, the more we realize we do not know. Students are introduced to the basic known facts about the universe, and how engineers help us explore the many mysteries of space.

The marine environment is unique and requires technologies that can use sound to gather information since there is little light underwater. The sea-floor is characterized using underwater sound and acoustical systems. Current technological innovations are allowing scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles allows scientists to map and understand the sea floor, and in some cases, the water column. In this lesson, the students will be shown benthic habitat images produced by GIS. These imaged will lead to a class discussion on why habitat mapping is useful and how current technology works to make bathymetry mapping possible. The teacher will then ask inquiry-based questions to have students brainstorm about the importance of bathymetry mapping.

With the assistance of a few teacher demonstrations (online animation, using a radiometer and rubbing hands), students review the concept of heat transfer through convection, conduction and radiation. Then they apply an understanding of these ideas as they use wireless temperature probes to investigate the heating capacity of different materials sand and water under heat lamps (or outside in full sunshine). The experiment models how radiant energy drives convection within the atmosphere and oceans, thus producing winds and weather conditions, while giving students the hands-on opportunity to understand the value of remote-sensing capabilities designed by engineers. Students collect and record temperature data on how fast sand and water heat and cool. Then they create multi-line graphs to display and compare their data, and discuss the need for efficient and reliable engineer-designed tools like wireless sensors in real-world applications.

Historically, seafloor mapping occurred with a simple data collection method: soundings. Soundings are taken by dropping a weight with a pre-measured rope off the side of a boat and noting the measurement on the rope when the weight hits the bottom. In this activity, student teams replicate the creation of seafloor bathymetry by taking a simplified form of soundings of an unseen seafloor model inside a shoebox and translating their collected data into a visualization of the topography, enabling them to better understand and appreciate modern remote sensing.

The marine environment is unique and because little light penetrates under water, technologies that use sound are required to gather information. The seafloor is characterized using underwater sound and acoustical systems. Current technological innovations enable scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles enables researchers to map and understand the sea floor. Similar technologies also aid in animal tracking, a method used within science and commercial industries. Through inquiry-based learning techniques, students learn the importance of habitat mapping and animal tracking.

Students learn about the remote sensing radio occultation technique and how engineers use it with GPS satellites to monitor and study the Earth's atmospheric activity. Students may be familiar with some everyday uses of GPS, but not as familiar with how GPS technology contributes to our ongoing need for great amounts of ever-changing global atmospheric data for accurate weather forecasting, storm tracking and climate change monitoring. GPS occultations are when GPS signals sent from one satellite to another are altered (delayed, refracted) by the atmosphere passed though, such that they can be analyzed to remotely learn about the planet's atmospheric conditions.
