Students act as R&D entrepreneurs, learning ways to research variables affecting the market of their proposed (hypothetical) products. They learn how to obtain numeric data using a variety of Internet tools and resources, sort and analyze the data using Excel and other software, and discover patterns and relationships that influence and guide decisions related to launching their products. First, student pairs research and collect pertinent consumer data, importing the data into spreadsheets. Then they clean, organize, chart and analyze the data to inform their product production and marketing plans. They calculate related statistics and gain proficiency in obtaining and finding relationships between variables, which is important in the work of engineers as well as for general technical literacy and decision-making. They summarize their work by suggesting product launch strategies and reporting their findings and conclusions in class presentations. A finding data tips handout, project/presentation grading rubric and alternative self-guided activity worksheet are provided. This activity is ideal for a high school statistics class.

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.

Students learn about biomedical engineering while designing, building and testing prototype surgical tools to treat cancer. Students also learn that if cancer cells are not removed quickly enough during testing, a cancerous tumor may grow exponentially and become more challenging to eliminate. Students practice iterative design as they improve their surgical tools during the activity.

Ecology: Population Growth is a Canadian adaptation of Connecting Concepts: Interactive Lessons in Biology by Robert Jeanne and Jan Cheetham (University of Wisconsin). It includes interactive lessons on exponential growth focusing on the zebra mussel population, logistic growth using fish as an example, and elephant population growth. / Croissance des populations est une adaptation canadienne de Connecting Concepts: Interactive Lessons in Biology de Robert Jeanne et Jan Cheetham (University of Wisconsin). Ces leçons interactives portent sur la croissance exponentielle à l’aide d’une population de moules zébrées, la croissance logistique selon l’exemple des poissons et la croissance d’une population d’éléphants.

The purpose of this task is to introduce students to exponential growth. While the context presents a classic example of exponential growth, it approaches it from a non-standard point of view. Instead of giving a starting value and asking for subsequent values, it gives an end value and asks about what happened in the past. The simple first question can generate a surprisingly lively discussion as students often think that the algae will grow linearly.

In this lesson, through various examples and activities, exponential growth and polynomial growth are compared to develop an insight about how quickly the number can grow or decay in exponentials. A basic knowledge of scientific notation, plotting graphs and finding intersection of two functions is assumed.

There is a description of the lesson that includes learning outcomes. This activity includes instructor guides, learning outcomes, student handouts, graphic organizers, and answer keys. There are two worksheets, one targeted to math students and the other targeted to biology/science students. Each worksheet is complemented with corresponding answer keys for faculty. There is background information, links to additional/supplemental information, teaching tips and a breakdown of the vocabulary differences between the math and biology classroom provided in the answer key handouts. Also, a link is provided to an original paper (Journal of Bacteriology, 1935) where bacterial growth rates were determined experimentally.
