Beaks as Tools: Selective Advantage in Changing Environments
Read the Fine Print
Rating
0.0 stars
Overview:

In their study of the medium ground finches, evolutionary biologists Peter and Rosemary Grant were able to track the evolution of beak size twice in an amazingly short period of time due to two major droughts that occurred in the 1970s and 1980s. This activity simulates the food availability during these droughts and demonstrates how rapidly natural selection can act when the environment changes. Students use two different types of tools to represent different beak types to see which is best adapted to collect and eat seeds of different sizes. Students collect and analyze data and draw conclusions about traits that offer a selective advantage under different environmental conditions. They have the option of using an Excel spreadsheet to calculate different descriptive statistics and interpret graphs.

The Cochlea
Read the Fine Print
Rating
3.0 stars
Overview:

This animation illustrates how we hear sound. Sounds from the outside world pass as vibrations through tiny bones in our ear to the cochlea. Within the coiled tube of the cochlea, different regions of the basilar membrane sense different sound frequencies at specific. This animation demonstrates how high-frequency sounds penetrate only a short distance along the basilar membrane and how vibrations from low tones are sensed at the farthest end of the basilar membrane.

Connect Past With Present: How Scientists Use Fossils to Draw Modern Conclusions
Read the Fine Print
Rating
5.0 stars
Overview:

In this lesson, students watch a video of scientists finding, collecting, and dating fossils. They then answer questions about scientific processes and work with ratios and proportions to solve simple algebraic equations relating to fossil data. Recommended for middle school life/earch science, high school environmental science, or high school biology.

Coral Bleaching Activity
Read the Fine Print
Rating
0.0 stars
Overview:

In this computer-based activity, students download, graph, and analyze authentic satellite temperature data for coral reef sites around the world. The activity includes a mapping component so the students work individually on one particular coral reef location and then the findings for the whole class are summarized on a set of world maps. After observing global trends in the data, students evaluate the threat to coral reefs from heat stress, which has been occurring with increased intensity and frequency in recent years.

The Day the Mesozoic Died
Read the Fine Print
Rating
0.0 stars
Overview:

This film traces the uncovering of key clues that led to the stunning discovery that an asteroid struck the Earth 66 million years ago, triggering a mass extinction of animals, plants, and even microorganisms. Each act illustrates the nature and power of the scientific method. Representing a rare instance in which many different disciplines (geology, physics, biology, chemistry, paleontology) contributed to a revolutionary theory, the film is intended for students in all science classes. Supporting materials are provided.
