MicroSTEM 7-19: Ionic Compounds

MicroSTEM 7-19: Ionic Compounds

Today, in MicroSTEM, the students built upon their knowledge of atoms and ions as they used their own bodies to represent atoms and ions that bond to form ionic compounds. The students played a game where they were challenged to find a partner “match” to create an ionic compound with a net charge of zero. Also, today in MicroSTEM, the students built simple ionic compounds and then created crystalline structures with the whole class.

Ask your students:  To create a neutral ionic compound with a Sodium ion (+1 charge), what charge would the other ion have to be? (-1 charge)

Integrated Science – Wednesday, 7-19

In the morning, students performed a Red Cross dialysis simulation lab using osmosis principles. They tested 12 mystery solutions to see which would be the best cleaning solution and the best dialysate solution. After they got their results, they made posters to compare with others. Visitors from Northern Illinois University who are doing research on exemplary STEM enrichment programs filmed the lab and interviewed teachers and students about their experience at IMSA this week. After lunch and free time, the students learned about photosynthesis and created their own experiments to demonstrate their knowledge. They were allowed to test several variables and their goal was to induce photosynthesis in a piece of spinach.

STEMvironment 7/19: Solar Power!

STEMvironment 7/19: Solar Power!

In class today, students learned how to apply the principles of solar energy, and how to run good tests of their solar device. Students created a solar oven that harnessed the power of the sun’s light to heat and cook marshmallows! By collecting data of their ovens’ temperature and then graphing it, students were able to compare their ovens, and discover some of the principles behind solar heating.

 Ask your student: What happened to the temperature inside the oven? (It increased) What part of the oven kept the heat in? (The black paper) What part reflected the heat inside of the oven? (The foil, which acted as a mirror)
