Day 4 activities
Looking at Bacteria Under a Microscope:
The children learned the types of bacteria living in a lagoon water treatment system and then viewed some of those bacteria under a microscope. This bacteria was taken from water samples from the local lagoon treatment facility which the children visited later that day.
Logan Lagoon Waste Water Treatment Facility Visit:
The children visited the local lagoon waste water treatment facility and they learned the process by which the waste water coming from Logan and the surrounding towns in the Cache valley area gets treated. They took a tour in the lagoons and learned how long it takes for the water to leave and go to the irrigation canal nearby. The children also gathered samples from the water output of the facility and performed chemistry tests on the water. One of the students said in their journal to the question Before today I thought "Waste water could never be used again" but now I think "It takes a long process but it can!" Another student said "Today I learned about how water treatment plants work and realized how much work it takes to clean the water.".
Hyrum Waster Water Treatment Plant Visit:
The children also visited the Hyrum mechanical treatment plant and saw the differences between the process used in a mostly natural treatment facility such as the lagoons as compared to a mostly mechanical facility like the Hyrum plant. The children also gathered samples from the water output of the facility and performed chemistry tests on the water. One of the students wrote in the journal: "Cleaning water is really hard and I am super grateful towards the people who work every day to clean water because I would never do the job myself." Another student answered the questions, Before today I thought : "That sewage would be way more thick" but now I think "That it is mostly water." One of the students wrote as an answer to the question what would you tell a friend about today's activities: "The place was really smelly but I think it was worth the knowledge. The E-coli (Bacteria) number was over 10 million before, but the number after they cleaned it was 0"
Creating Posters and Presentations:
Having collected data all week, the children split into their groups and worked for a few hours on creating both a poster presentation and a slide presentation about what they learned throughout the week.
