STEMvironment 7/17: “Renew-a-Bean”
“Unless someone like you cares a whole awful lot, nothing is going to get better. It’s not.” This week our environmental scientists are exploring the concepts of renewable and nonrenewable energy with help from Dr. Suess’ The Lorax. Today students discovered how quickly nonrenewable energy is used up by playing “Renew-A-Bean.”
Ask your student: What is an example of a renewable resource? What is an example of nonrenewable resource? (Renewabe resource: hydropower, solar power, wind power; Nonrenewable resource: coal, minerals, fossil fuels)
MicroSTEM 7-17: Bacteria Among Us
Students began a two day project today, investigating bacteria that surrounds us. Each student will test their own fingers, and each group of 4 students could pick up to 8 different surfaces to see what kinds of bacteria live there. Alternatively, the students could choose to see what happened to the bacteria from the same surface with some sort of treatment (applying hand sanitizer, soap, etc.). Students were given the chance to make a hypothesis about what they expect to see on their plates. Later on this week, the students will use a microscope to look at the results of their samples, and test their hypotheses.
Ask your student: If bacteria surrounds us, why don’t we get sick more often? (Not all bacteria are pathogenic (disease causing)) What are some examples of places where good bacteria are found? (Almost anywhere has some amount of good bacteria, some examples would be in our intestines and mouth)
Integrated Science Program – Monday 7-17-17
Today was the first day of the Integrated Science Residential Program. In the morning, the students explored polarity in a lab setting. They determined if 6 different solutions were polar or nonpolar by seeing if the solution was attracted to a charged rod. They created posters with their conclusions, and created posters about the field of science. Then the students ate lunch and tie-dyed name tags. After lunch, they began to research their topic for their week-long project on water and ecosystems. Finally, they did a lab to compare dissolving and reacting by combining different solutions in test tubes and recording their observations.
