Faculty and their graduate students work with the Dartmouth Center for the Advancement of Learning (DCAL) to develop inquiry-based science 'modules' related to their research. Ideally, these modules are 1-2 hours in length and incorporate hands-on activities. Training through DCAL is available on the development of effective inquiry-based modules. Once a module is developed it is published on the Dartmouth Outreach website and Sara Riordan, Science Outreach Coordinator, will connect researchers with K-12 teachers in the area who might be interested in adopting the module or having a graduate student or faculty member visit their classroom to present the module.

developed by Simone Whitecloud, PhD Candidate**Teacher training: Measuring Photosynthesis and Respiration in real time with an Infared Gas Analyzer (IRGA),**

** Supporting Materials: IRGA Welcome presentation for teachers; IRGA Instructional Video1; IRGA Instructional Video2, IRGA Instructional Video3**This lesson introduces how an instructor may use an Infrared Gas Analyzer (IRGA) to teach students about photosynthesis and cellular respiration by measuring carbon dioxide uptake and release in plants. From CO2 levels, the IRGA calculates the photosynthesis and respiration rates of plants, which allows students to see how these rates change in response to various environmental conditions. For example, students can observe a plant switching from photosynthesis to respiration when sunlight is removed, or can see changes in photosynthetic rate in response to watering with cold versus warm water. This lesson serves well to connect cellular respiration and photosynthesis once the students have understood the concepts of each, and fits well with Science Standards for grades 7 & 8, although the IRGA could easily be used by more advanced students for a research project/science fair project. For instance, I used it for my PhD.

This lab uses crayons as substitutes for rock so that students can gain first hand experience with the rock cycle completing something that usually takes millions of years in 50 minutes.

**McNuggets Module**developed by Zeb Engberg, PhD Candidate, Department of Mathematics, with Jeanine King

**Overview: **McNuggets are a chicken-related food sold by McDonalds. In the final decade of the last century, McNuggets could be purchased in boxes of 6, 9, and 20. As a customer, what possible amounts of McNuggets are you able to order from McDonalds? For example, it is possible to order 15 McNuggets because it can be obtained from a box of 6 and a box of 9. On the other hand, it is impossible to order 16 McNuggets. A McNugget number is an integer that can be obtained by adding together a combination of McNuggets coming from boxes of 6, 9, and 20 McNuggets. Conversely, a non-McNugget number is an integer which cannot be obtained from any combination of 6, 9, or 20 McNuggets. In the mathematical community, this sort of problem is generally called the *Frobenius* problem (see the Mathworld article or Wikipedia entry for more information), and it can be phrased in terms of postage stamp values, coins, points-values in a game of football, etc. There are many interesting unsolved problems connected to the* Frobenius* problem.

**Overview:** This module explores the concepts of freezing point depression, heat transfer, hydrogen bonding, and material science while asking the question, "why does ice cream have a smooth, soft consistency, while frozen water or milk is hard?"

**Building Motions in Earthquakes,**developed by Vicki V. May, PhD, Instructional Associate Professor, Thayer School of Engineering at Dartmouth College; Adapted from:*FEMA Seismic Sleuths and SDSC TeacherTech Science Series*

**Overview: **During an earthquake, buildings move – or oscillate. If the frequency of this oscillation is close to the natural frequency of the building, resonance may cause severe damage. This lesson encourages students to observe how the mass, stiffness, and height of buildings affect their motion and how buildings respond to resonant motions.

**Thinking Like Plants and Pollinators**, developed by Zak Gezon, PhD Candidate, Department of Ecology and Evolutionary Biology, with Sue Jukosky and Rebecca Irwin

**Overview:** About 90% of flowering plants rely on bees and other animals for reproduction through pollination. Pollinators, in turn, benefit from plants by receiving food in the form of nectar and pollen. This "win-win" relationship between plants and pollinators is called a mutualism. This lesson encourages students to understand mutualisms from the POV of both plants and pollinators, and gain an intuition for the effects that human disturbance can have on plant- pollinator interactions.

**Exploring the Stroop Effect,**developed by Sergey Fogelson, PhD Candidate, Department of Psychological and Brain Sciences, and Rick Schluntz; Adapted from: http://www.ithaca.edu/faculty/stephens/stroopi.html

**Overview: **Mental operations can come into conflict with each other. For example, it is exceedingly difficult to both remember a list of 15 words and count backwards from 500 in multiples of 7. This is because distinct mental processes (remembering, computing a number) can share mental resources. This lesson explores a similar kind of mental conflict directly, by replicating a famous psychological effect discovered by John Ridley Stroop.

**From DNA to Protein**, developed by Jessica Day, PhD Candidate, Department of Biochemistry

**Supporting materials:*** Worksheet for From DNA to Protein*
