If you're like me, you hate writing "needs support" and/or "lacks evidence" on students' papers. If you do this activity, you won't have to (as much). Here's how it works.

This case study was written for an introductory course for biology majors who are first learning about embryonic development. The case is composed of several parts and involves a storyline about a team of researchers who find frogs and eggs in bamboo plants during a field study. Students consider what these observations mean, learn basics about the stages of animal embryonic development, and make connections to phylogeny and natural selection. Students then apply their understanding of animal embryonic stage development to the chemical atrazine in the environment by examining data from several experiments. As a concluding activity students write a letter to an agency or newspaper of their choosing stating their opinion surrounding the use of atrazine in the environment. The case proceeds in a progressive disclosure format and involves a combination of class discussion, small group work, and homework. Because the case focuses on very basic animal embryonic development, it would also be a great start to a developmental biology course or an embryology course.

This case study was developed to teach students the importance of understanding the behavior of wildlife, explore the difficulty in making management decisions when the public is invested in a species, and to help students develop critical thinking and public speaking skills. Students learn about the conservation status and behavior of the black rhinoceros by reading a primary literature article and answering a series of questions. They then listen to a Radiolab podcast that explores the moral dilemma of whether it is ethically appropriate to shoot an endangered rhinoceros if the purpose is to raise conservation funds. Students are assigned one of five positions and write essays to prepare for a town hall style debate in which they examine the pros and cons of such a decision. The Radiolab podcast is based on real events, and is also representative of many ethical dilemmas that wildlife managers regularly face. This case study is appropriate for several upper division biology courses.

This 5 lesson unit, which was designed by teachers in conjunction with scientists, ethicists, and curriculum developers, explores the scientific and ethical issues involved in stem cell research. The unit begins with an exploration of planaria as a model organism for stem cell research. Next, students identify stages in the development of human embryos and compare the types and potency of stem cells. Students learn about a variety of techniques used for obtaining stem cells and the scientific and ethical implications of those techniques. While exploring the ethics of stem cell research, students will develop an awareness of the many shades of gray that exist among positions of stakeholders in the debate. Students will be provided an opportunity to become familiar with policies and regulations for stem cell research that are currently in place in the United States, the issues regarding private and public funding, and the implications for treatment of disease and advancement of scientific knowledge. The unit culminates with students developing a position on embryonic stem cell research through the use of a Decision-Making Framework. Two culminating assessments are offered: In the individual assessment, students write a letter to the President or the President's Bioethics Committee describing their position and recommendations; In the group assessment, students develop a proposal for NIH funding to research treatment for a chosen disease using either embryonic or 'adult' stem cells.

Aligned with both the Next Generation Science Standards and the Common Core State Standards, the investigations are designed to be much more authentic than traditional laboratory activities-and they enable your students to learn how to read, write, speak, and use math in the context of science.

A mother who didn't believe in vaccines for years is now writing about her experience after all seven of her children became sick with whooping cough and hopes to inspire other parents to reconsider vaccination.

"We have found that the best way to keep a record of activity and ideas is to create a table with four columns-1) Activities we did, 2) Patterns or observations, what happened?, 3) What do you think caused these patterns or observations?, 4) How do these patterns help us think about the essential question or puzzling phenomenon?
