This lesson introduces the ways that engineers study and harness the wind. Students will learn about the different kinds of winds and how to measure wind direction. In addition, students will learn how air pressure creates winds and how engineers build and test wind turbines to harness energy from wind.
In this activity, students learn about ocean currents and the difference between salt and fresh water. They use colored ice cubes to see how cold and warm water mix and how this mixing causes currents. Also, students learn how surface currents occur due to wind streams. Lastly, they learn how fresh water floats on top of salt water, the difference between water in the ocean and fresh water throughout the planet, and how engineers are involved in the design of ocean water systems for human use.

This lesson provides a basic introduction to celestial navigation for navigators, sailors, and others interested in the topic. It begins with the relationship between celestial coordinates and Earth coordinates and examines key celestial navigation parameters—geographic position, sextant altitude, observed altitude, azimuth, and computed altitude—that can be used to identify to a ship's position. A U.S. Navy navigator demonstrates the main celestial sights performed over the course of a day, including the morning three-star fix, morning Sun line, Local Apparent Noon Sun line, afternoon Sun line, and evening three-star fix, and demonstrates how the sight reduction culminates in a marked intercept and line of position on a navigation plot. The concepts of fix, running fix, estimated position, dead reckoning, and assumed position are also discussed. Although no formal background is needed for this lesson, some familiarity with the basics of navigation and the Universal Plotting Sheet will be useful to the learner.
In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios. This resource includes background information about the Coriolis effect and helpful hints.
Build a model of the Earth, with its spin-axis, and a lamp as the Sun to demonstrate the concept of seasons.
--Understanding why we have seasons and the cause of seasonal variation in temperature.
--Learning about how the Earth rotates on a tilted axis compared to its orbit around the Sun.
--Students learn about seasons by building a model of the Earth and the Sun, and investigating how sunlight hits the Northern and Southern Hemispheres during different seasons.
--Students explain that the same amount of light hitting the ground heats up a small area more than a large area
--Students show that the angle at which the sunlight hits the Earth influences how much the sunlight heats up the Earth.
Students demonstrate that the angle at which the sunlight hits the Earth is related to the tilt of the Earth’s rotational axis compared to the Earth’s orbit around the Sun.
This free, standards-based website developed for elementary teachers provides hand-picked, reviewed, on-line resources to enhance teacher content knowledge regarding reasons for the seasons.

How does our climate affect us? How do we decide what to wear each day? What factors determine if our clothing choices are comfortable? What is the source of our water? Students explore characteristics that define climatic regions. They learn how tropical, desert, coastal and alpine climates result in different lifestyle, clothing, water source and food options for the people who live there. They learn that a location's latitude, altitude, land features, weather conditions, and distance from large bodies of water, determines its climate. Students discuss how engineers help us adapt to all climates by designing clothing, shelters, weather technologies and clean water systems.
In this lesson, students are shown the very basics of navigation. The concepts of relative and absolute location, latitude, longitude and cardinal directions are discussed, as well as the use and principles of a map and compass.
