Exploring Technology, Third Edition



Unit 2: Technology Changes History

Lesson 2: Technology Through Time

Student Resource 2.2.3: Design Brief: 3-D Timeline

Background:

Your school is planning a World History Night and the goal is to have every student participate in the events. Some classes are planning short plays of significant events, live action dioramas, posters and models of artifacts from pre-historic times to the present. The Technology Department has decided to participate by constructing a 3-Dimensional Timeline that will illustrate the development of various technologies through the ages. You have already spent a considerable amount of time researching a current technological artifact from one of the following areas of technology: agriculture, manufacturing, sanitation and medicine, transportation, information processing, and communications.

Design Problem:

Your teacher has asked you to design and build three models of the artifact from the Engagement activity to create a three-dimensional timeline of that device through history.

Specifications:

1. Each artifact should fit into a shoe box and have a scale with it to help people visualize the actual size of the artifact.

2. Each model must be from a different Age and labeled as such: Predicted Future, Information, Industrial, Renaissance/Enlightenment, Middle Ages, Iron, Bronze, Neolithic, Mesolithic, or Paleolithic.

3. The first model must be what the artifact looked like when it first appeared in the historical record. The third model will be what the artifact looks like today or in the predicted future. The second artifact will be what the artifact looked like about half way between the other two models

4. The artifacts will be dated.

Deliverables:

1. Each student will submit 3 assembled models.

2. Each student must submit a learning objective summary for the project.

This rubric will be used to evaluate your extension activity:

Standards Addressed:

For your learning objective summary, explain three of the five STL standards and the AAAS standard using supporting details you learned from the lesson.

o The Iron Age was defined by the use of iron and steel as the primary materials for tools. (STL 7K)

o The Middle Ages saw the development of many technological devices that produced long-lasting effects on technology and society. (STL 7L)

o The Renaissance, a time of rebirth of the arts and humanities, was also an important development in the history of technology. (STL 7M)

o The Industrial Revolution saw the development of continuous manufacturing, sophisticated transportation and communication systems, advanced construction practices, and improved education and leisure time. (STL 7N)

o The Information Age places emphasis on the processing and exchange of information. (STL 7O)

o Technology is largely responsible for the great revolutions in agriculture, manufacturing, sanitation and medicine, warfare, transportation, information processing, and communications that have radically changed how people live and
