Description<\/em><\/h3>\n

Provide students with the full story for Part One of the pathway:<\/p>\n

Farmers at Sunrise Farm are planting crops for the season. \u00a0They spread fertilizer on the field. \u00a0The fertilizer contains chemical nutrients that help 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 the pond. \u00a0<\/em><\/p>\n

Sunrise Farm Pond, like all ponds, has some algae growth. \u00a0The algae grow slowly and have a very short lifespan. \u00a0When the fertilizer runs into the pond, the chemical nutrients that help the crops grow also help the algae grow and reproduce much faster than they had previously. <\/em><\/p>\n

The algae grow thick at the top of the water, which makes the water cloudy and blocks the sunlight from getting to the bottom of the pond where many producers live. \u00a0As a result, it is difficult for the producers to grow, and they eventually die. \u00a0The producers at the bottom of the pond make much of the oxygen that the pond needs, and as they die, the amount of oxygen in the pond from these producers decreases.<\/em><\/p>\n

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

Why are the fish dying at Sunrise Farm Pond?<\/em><\/p>\n

After sharing the full Part One story, use the Questions to Ask Students in a class discussion to encourage students to consider how their models relate to events in the story.\u00a0 Finally, tell students that they will explore how decreased oxygen is connected to fish dying at Sunrise Farm Pond.<\/p>\n
