 __Name of Session: Oh Just Grow Up Already!__  __Session Leaders:__ Joy and Sally  __Length of Session:__ Part 1 (Day 1): 1 hour, 15 minutes Part 2 (Day 8): 45 minutes  __Learning Goals for DVI Fellows:__ The Learner will: ·  Understand the nature of germination and the function of seed structures (Part 1). ·  Be able to distinguish between manipulated (independent), controlled, and responding (dependent) variables (Part 1). ·  Understand how to develop an experiment to further explore personal observations and questions designed by the investigator (Part 1). ·  Explain the initial stages of plant development through daily observations (Part 2). ·  Realize that environmental conditions have an influence on individual seed success (Part 2). ·  <span style="FONT-FAMILY: 'Arial','sans-serif'">Graph experimental outcomes (Part 2). <span style="FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-FAMILY: 'Arial','sans-serif'">__Summary of Activities:__ <span style="FONT-FAMILY: 'Arial','sans-serif'">__Materials Required:__ <span style="FONT-FAMILY: 'Arial','sans-serif'">Peanuts <span style="FONT-FAMILY: 'Arial','sans-serif'">Easel-sized Sticky Pads <span style="FONT-FAMILY: 'Arial','sans-serif'">Sticky notes <span style="FONT-FAMILY: 'Arial','sans-serif'">Markers <span style="FONT-FAMILY: 'Arial','sans-serif'">Paper Towels <span style="FONT-FAMILY: 'Arial','sans-serif'">Staplers <span style="FONT-FAMILY: 'Arial','sans-serif'">Quart size Ziploc bags (~60) <span style="FONT-FAMILY: 'Arial','sans-serif'">Lima Bean Seeds (~500, soaked O/N) <span style="FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-FAMILY: 'Arial','sans-serif'">__Session Overview:__

// Engage //
<span style="FONT-FAMILY: 'Arial','sans-serif'"> //<span style="FONT-FAMILY: 'Arial','sans-serif'">Explore //<span style="FONT-FAMILY: 'Arial','sans-serif'">
 * <span style="FONT-FAMILY: 'Arial','sans-serif'">The “Anatomy of an Investigation” will be discussed as an introduction to inquiry projects and using inquiry boards. Inquiry boards will be used to begin the exercise, allowing fellows to brainstorm ideas for their projects and discuss the differences between dependent and independent variables. In addition, pertinent background information will be presented regarding seed structure and germination (Part 1).
 * <span style="FONT-FAMILY: 'Arial','sans-serif'">Fellows will dissect seeds and explore their anatomy (Cotyledons and Embryo). They will also compare different seeds and explore the differences between monocots and dicots (Part 1).

// Explain //

 * <span style="FONT-FAMILY: 'Arial','sans-serif'">Fellows will observe germinating seeds that were set up at different time periods prior to this workshop (1 night, 1 week, 2 weeks prior). In groups, they will discuss how germination occurs, and the role that the cotyledons play in the process. They will address questions about why are seeds are used as a food source and how seeds are able to germinate in the absence of light (e.g. in the dark ground) (Part 1).
 * <span style="FONT-FAMILY: 'Arial','sans-serif'">Fellows will discuss the influence of different environmental conditions on the germination of seeds (Part 1).
 * <span style="FONT-FAMILY: 'Arial','sans-serif'">The difference between manipulated, controlled, and responding variables will be discussed and possible variables that could be altered in seed germination will be brainstormed. Fellows will also make predictions about the outcome of experiments (Part 1).

// Elaborate //

 * <span style="FONT-FAMILY: 'Arial','sans-serif'">Fellows will work in pairs to set up the experiments to test their predictions (Part 1).
 * <span style="FONT-FAMILY: 'Arial','sans-serif'">Fellows will observe and record changes in their seeds over a one week time period (Part 2).
