In this hands-on, minds-on activity, students investigate the biological causes of Maria’s symptoms and Jayden’s symptoms. To explore the causes of these symptoms, students carry out two experiments and interpret the results, and they answer additional analysis and discussion questions.

Students learn about enzyme function and enzyme specificity as they figure out that Maria’s symptoms are due to lactase deficiency (resulting in lactose intolerance) and Jayden’s symptoms are due to sucrase deficiency.

In the final section, students are challenged to generalize their understanding of enzymes to interpret a video of an experiment with saliva, starch and iodine. This activity can be used in an introductory unit on biological molecules or later during a discussion of enzymes.

This analysis and discussion activity helps students to understand the relationships between food, physical activity, cellular respiration, and changes in body weight. Analysis of a representative scenario helps students to understand how challenging it is to prevent weight gain by exercising to offset what seems to be a relatively modest lunch.

In an optional research project, each student asks an additional question and prepares a report based on recommended reliable internet sources.

The Student Handout is available in the first two attached files and as a Google doc designed for use in distance learning and online instruction. The Teacher Notes, available in the last two attached files, provide instructional suggestions and background information and explain how this activity is aligned with the Next Generation Science Standards.

The Teacher Notes present a sequence of activities that will help students understand the basic structure and function of proteins and DNA.

To understand how genes influence our characteristics, students learn that different versions of a protein can result in different characteristics, and a gene in the DNA determines which version of a protein is synthesized by a person’s cells.

This information is conveyed through a PowerPoint with a sequence of discussion questions and videos, a Student Handout, and an optional hands-on learning activity. This sequence can be used in an introductory unit on biological molecules or to introduce a unit on molecular biology.

This game reviews introductory chemistry, including organic compounds and chemical reactions. To access the game, open the PowerPoint attachment below; in full screen display, click on the slideshow icon on the right in the bottom bar. Clicking on a number in the gameboard will bring you to a question. When that question has been answered click on the yellow box in the lower right corner and you'll be brought back to the gameboard screen.  Spaces for questions that have already been answered will now appear blank, just like on the TV show. 

 Two ways of organizing the Jeopardy game are recommended in the Teacher Notes available in the second attachment below.

Students in Brain, Education, and Inquiry at Bryn Mawr College write web papers on topics of interest to themselves. These are made available via links from the index below to encourage further exploration by others having similar or related interests. All papers have associated on-line forums for continuing conversation.
