Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Measuring Noise Pollution
Read the Fine Print
Educational Use
Rating

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.

What Happened to the Water? Designing Ways to Get and Clean Water
Read the Fine Print
Educational Use
Rating

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.

Wonder #73: Why is Pluto No Longer a Planet?
Only Sharing Permitted

Rating

In this lesson, students will hone their investigative skills and form an opinion based on the credible evidence that they uncover. After learning about the decision to deem Pluto a "dwarf planet," students will have time for individual investigation. After using their background knowledge to choose credible sources, they will analyze the information they gather to form their own opinion, which they will support in a video response to a prompt on Flipgrid.
