This article provides two activities, exploring genetic drift of small breeding populations, highlighting the black-footed ferret ("Mustela nigripes"). According to the U.S. Fish and Wildlife service, all black-footed ferrets are descended from 18 individuals, making them extremely vulnerable to genetic drift. They were thought to be…

Science is full of amazing facts, but at times it may be difficult to fully appreciate their significance without an understanding of the scientific practices that gave them meaning. The teaching of evolution may be an example of this situation; there are many interesting facts to consider, but it is equally important for students to learn where…

One way to tackle climate misconceptions is to have students work with data to show how the climate is changing in their local community. The National Oceanic and Atmospheric Administration (NOAA) has weather stations nationwide that collect data on air temperature and precipitation that are freely available online. This article describes a lesson…

Many students probably take pictures daily. Whether snapshots of their friends at a Justin Bieber concert or of their latest skateboard trick, these images document changes in a student's life. Digital cameras can do more, however, than record memories to post on Facebook. They can also help students examine changes in their environment. This…

In science, inquiry is used as students explore important and interesting questions concerning the world around them. In mathematics, one contemporary inquiry approach is to create models that describe real phenomena. Creating mathematical models using spreadsheets can help students learn at deep levels in both science and mathematics, and give…

Describes student-friendly data sets accessible over the Internet that enable students to use large sets of real data to create graphs, apply basic statistical techniques, construct models, and draw conclusions about how the earth functions. Lists useful online data sets. (JRH)

With schools being asked to accomplish more and more, it is increasingly important to, whenever possible, address multiple goals in teaching. Educating the whole child dictates that we find ways to ensure our graduates are well-rounded, independent thinkers capable of becoming well-adjusted, contributing adults. Thus community service has become a…

Presented is an activity in which students work in research teams to gather data, integrate computer analyses, and discover the relationships between variables by using a second class lever. A diagram of the lever, a list of processes involved in this activity, and an idealized data table are included. (KR)

Describes how spreadsheets can be used for helping students learn about direct current electrical circuits. (PR)

Described is the generation of a scale model of the solar system and the milky way galaxy using a computer spreadsheet program. A sample spreadsheet including cell formulas is provided. Suggestions for using this activity as a teaching technique are included. (CW)

This article describes how Cahokia middle and high school students conduct inquiry-based science through a pitfall trap experiment. In a collaborative effort, students designed and conducted pitfall trap investigations that combined their interest in the natural world with their love of technology. The students set up their own experiments to…

Describes a two-week lesson on electric fields that combined lecture, interactive video, lab experimentation, computer spread sheets, and computer-assisted-graphing. (PR)
