Science@IMSA – Tuesday: Carbon Burger

Science@IMSA – Tuesday: Carbon Burger

Our environmentalists resumed their understanding of people’s impact on the Earth.  Today, we learned just how much carbon dioxide is produced in the production of a single cheeseburger. Raising and harvesting the meat, growing and collecting the toppings, and shipping all of the food adds up to a large footprint for just one burger. Students calculated these emissions themselves to get more perspective about their environmental impact.

Ask your student:

What’s the largest source of carbon dioxide in the production of a burger? (Shipping / factory)

Does this change the way you feel about your food?

STEMvironment-Tuesday: The Greenhouse Effect

STEMvironment-Tuesday: The Greenhouse Effect

The greenhouse effect happens when certain gases—known as greenhouse gases—collect in Earth’s atmosphere. These gases include carbon dioxide (CO2), methane, nitrous oxide (N2O), fluorinated gases, and ozone. Today our STEMvironmentalists used data inputs on normal versus actual temperatures in Aurora, IL to identify the pattern of increasing or decreasing on a bar graph. Then they did a lab which helped them deduce the mechanism of greenhouse gases.

Ask your student:

  • What Greenhouse gas is largest contributor to the rising temperatures? (CO2)
  • What can we do to limit this gas?

Gold Medal STEM – Tuesday: Mechanical Swimmer: Materials Analysis

Gold Medal STEM – Tuesday: Mechanical Swimmer: Materials Analysis

Our Olympic engineers were able to analyze the necessary materials for a mechanical swimmer. Bags of materials were categorized by their characteristics and functions. Once they had an understanding of the parts, our students created poster diagrams to display their ideas about the best use of the materials. Everyone shared their analyses to the class by doing a gallery walk.

Ask your student:

What are some material categories? (Adhesives, platforms, buoyancy, support, measurement)

Which materials might have more than one application? How could they also be used?

C.S.IMSA Belleville – Tuesday: Lift a Finger

C.S.IMSA Belleville – Tuesday: Lift a Finger

Our CSI team is well on its way to cracking the case! Today, the scientists-in-training delved into the study of fingerprints. They first fingerprinted themselves in order to learn about the different recognizable fingerprint patterns. Students then examined the fingerprint evidence collected from the crime scene and attempted to match it with prints collected later from suspects.

Our investigators have had a busy two days, but there is more forensic science to be done before the culprit can be apprehended!

Ask your student:

What are the three characteristic fingerprint patterns? (loops, whorls, and arches)

After two days, do you have any theories about the case?
