This week's slideshow highlights: students observing the transfer of energy between organisms and predator prey relationships in our classroom Lake Michigan Aquatic Ecosystem during feeding times; 6th grade students have been busy working in cooperative groups of engineers to design experiments backed up by their team's research to test variables that impact the effectiveness of "green roofs", which they learned can help combat problems such as the "Urban Heat Island Effect" and urban runoff that often leads to increased flooding of cities like Chicago; an 8th grade scientists setting up their STEM Fair Project experiment that they devised to investigate natural substances that can be used to fight bacteria on surfaces; and 5th grade class enjoying some hard-earned game time as they played cooperative board games and card games at the end of class on Friday to continue to strengthen our classroom community! Thank you for checking in with us this week!
