This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device. By creating a place where the movement of the Sun could be tracked day after day, Chacoans could mark the passage of time and gain an idea of when seasons were changing. If the Chacoans could use a particular location and the Sun to tell them about time, can we use time and the Sun to tell us about our location? In this easy experiment, you'll see how the position of the Sun in the sky is related to where we are on the earth.
In this activity, learners explore the "nuts and bolts" of gene chips. Learners construct a simple model of a DNA microarray (also known as gene chips) and learn how microarrays can be used to identify and treat disease--including cancer. This resource includes references and an explanation of microarrays.
Students complete a short survey to establish their beliefs about technology. They compare their opinions to the ideas in a novel that depicts technology (such as 1984 or Fahrenheit 451).
This lesson plan asks students to pay attention to the technologies they use. They graphically map their interactions with technology and compose narratives of their most significant interactions with technology.
In this unit, students will explore the different forms of transportation over time—from the New World and early America, to present day—and their impact on society and the environment (Change and Continuity). They will explore the impact of the different forms of transportation on economics, migration, and geography (where people live and how they adapt their environment to their transportation need), as well as how to become critical readers by gathering information from a variety of primary and secondary sources to understand the impact of transportation on history.
This version of the subject Technology Dynamics and Transition Management was taught in co-operation with the Harbin Institute of Technology in China. At the heart of this module lies a model of technology development from a social perspective, which will be applied to water problems in present-day China.
This interactive activity from A Science Odyssey offers a historic tour of 20th century home technologies.
