Mystery at Sunrise Farm Pond with students:<\/p>\n<p><em>Farmers at Sunrise Farm are planting crops for the season. \u00a0They spread fertilizer on the field. \u00a0The fertilizer contains chemical <a href=\"https:\/\/www.horizon-research.com\/ASSET\/food-vs-nutrient\/\" target=\"_blank\" rel=\"noopener\">nutrients<\/a><\/em><em> that help the plants grow. \u00a0Much of the fertilizer is used by the plants or absorbed by the soil, but not all. \u00a0When it rains, some of the fertilizer goes into the stream by the field and flows into Sunrise Farm Pond. \u00a0<\/em><\/p>\n<p><em>When one of the farmers checks on the pond a few months after planting the crops, she finds that several of the fish have died. <\/em><\/p>\n<p><em>Why are the fish dying at Sunrise Farm Pond?<\/em><\/p>\n<p>Provide time for students to ask questions about the story (for example about unfamiliar ideas or vocabulary) and the driving question (Why are the fish dying at Sunrise Farm Pond?) as needed.\u00a0 Students then make a drawing of what they think might be important for answering the driving question using the <a href=\"https:\/\/www.horizon-research.com\/ASSET\/wp-content\/uploads\/2018\/01\/5-pond-template.pdf\" target=\"_blank\" rel=\"noopener\">pond cross-section template<\/a>.<\/p>\n<h3><em>Questions to Ask Students<\/em><\/h3>\n<ul>\n<li>What plants or animals do you think are important to include in your drawing to explain why the fish died?<\/li>\n<li>What do you think happens to the fertilizer when it goes into the pond?<\/li>\n<li>How might the fertilizer in the pond lead to dead fish in the pond?<\/li>\n<\/ul>\n<h3><em>Student Thinking<\/em><\/h3>\n<p>Some students may believe that fertilizer is food for plants, and maybe even for other organisms.\u00a0 Students may have little basis for relating the fertilizer to fish death.\u00a0 Alternatively, the fish death may reinforce a student\u2019s <em>incorrect<\/em> idea that all chemical substances humans use are toxic.\u00a0 These students may be especially tempted to make a direct causal link between the fertilizer in the pond and the dead fish.<\/p>\n<div class=\"su-box su-box-style-default\" id=\"\" style=\"border-color:#087c19;border-radius:3px;\"><div class=\"su-box-title\"

Have students consider the limitations and affordances of their model as a representation.\u00a0 Students&#8217; initial\u00a0models\u00a0will serve as a representation of what they understand so far about the situation at Sunrise Farm Pond.\u00a0 As their\u00a0models increase in complexity over time, they will become tools that students can use to construct an explanation of the cause-and-effect relationships present in the pond. <\/div><\/div>\n<div class=\"su-note\"  style=\"border-color:#a5c3e0;border-radius:3px;-moz-border-radius:3px;-webkit-border-radius:3px;\"><div class=\"su-note-inner su-u-clearfix su-u-trim\" style=\"background-color:#bfddfa;border-color:#ffffff;color:#333333;border-radius:3px;-moz-border-radius:3px;-webkit-border-radius:3px;\">\n<b> <a href=\"https:\/\/ngss.nsta.org\/Practices.aspx?id=1\" target=\"_blank\" rel=\"noopener\">Asking Questions<\/a> <\/b> In addition to providing students an opportunity to ask clarifying questions about the story, provide students with time to generate questions about aspects of the pond they think would be important to investigate, prior to posing the suggested questions above. One approach is to have students write down each of their questions on a sticky note, and then as a class, organize the questions based on their focus. When student experiences later in the pathway address these questions, revisit the collection of questions as a class, encouraging students to identify which questions they are now able to answer. For example, students may ask, &#8220;What does the fertilizer do to the pond water?&#8221; and after engaging in Student Experience 3, they will have evidence to support the idea that fertilizer entering the pond causes accelerated algae growth. <\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Purposes To introduce students to the specific scenario and driving question, which form the basis for this pathway.
