Mascaro Center Green Week
The University of Pittsburgh Mascaro Center for Sustainable Innovation came for a week in September to work with students in the 6th grade, focusing on on understanding aspects of sustainability. They tried to impress on the students the need to think about how we use our resources so that future generations may also have the opportunity to use them as well. The Mascaro Center talked about how electricity is made, including the resources used in electricity generation. The students were even able to make a model of a wind turbine and test it. They also discussed how we use water and how it is treated before it comes to our sinks. The week was concluded with a Jeopardy game where the students were able to win prizes!
Mascaro Center Electricity and Water Activities
The Mascaro Center also worked with the 7th and 8th graders twice this year, presenting more in-depth information on electricity and water sanitation. At the end of the electricity lesson, students were able to build and test a model of a solar panel house and experiment with a way of making electricity using lemons. They thoroughly enjoyed the activity. The water lesson was very informative also. After learning about how developing countries clean their water, students were challenged to test the various models. They were able to test the pH and other aspects of the water to see how clean it was.
Pitt Mobile Lab
In September, the Pitt Mobile Lab pulled up to MACS and worked with middle school students on understanding the processes of osmosis and diffusion. The students were broken into small groups and able to participate in hands-on activities that let them see osmosis and diffusion in action.
The diffusion group experimented with iodine passing through a permeable membrane to interact with starch and turn it purple. The osmosis group conducted an experiment to see how gummy bears react when placed in hypotonic, hypertonic and isotonic solutions. At the end of the activities, the students discussed their results and show what they had learned.
Thanks to our friends at the Mascaro Center and Pitt Mobile Lab for helping our middle schoolers to understand the real-world applications of science!
