This unit introduces students to the purpose and practice of media literacy. It includes pre- and post-visit activities designed to bracket the Believe It or Not? ED Class ( The activities also can be done independent of a visit to the Newseum.) Students will come to understand why not all information is trustworthy and how to differentiate the good from the bad. They practice using a set of tools – the consumer’s questions – to deconstruct and evaluate information sources.

A resource for credible Business and related sources that can be given to students who conducting research in the discipline. The hyper-doc lists a variety of sources with links to websites. It is a downloadable, pdf file.

Through investigating the nature, sources and level of noise produced in their environment, students are introduced to the concept of noise pollution. They learn about the undesirable and disturbing effects of noise and the resulting consequences on people's health, as well as on the health of the environment. They use a sound level meter that consists of a sound sensor attached to the LEGO® NXT Intelligent Brick to record the noise level emitted by various sources. They are introduced to engineering concepts such as sensors, decibel (dB) measurements, and sound pressure used to measure the noise level. Students are introduced to impairments resulting from noise exposure such as speech interference, hearing loss, sleep disruption and reduced productivity. They identify potential noise pollution sources, and based on recorded data, they classify these sources into levels of annoyance. Students also explore the technologies designed by engineers to protect against the harmful effects of noise pollution.

Students become familiar with the concept of a communication system, its various parts and functions. To do this, they encode, decode, transmit, receive and store messages for a hypothetical rescue mission, using a code sheet and flashlight for this process.They also maintain storage sheets from which they can retrieve information as it is required.

In this scenario-based activity, students design ways to either clean a water source or find a new water source, depending on given hypothetical family scenarios. They act as engineers to draw and write about what they could do to provide water to a community facing a water crisis. They also learn the basic steps of the engineering design process.
