Springfield Engineering Explorations 8/2: A Series of Circuitous Events
In this lesson, our engineers applied the knowledge they learned earlier in the week in a race to assemble two different types of circuits, parallel and series. Their creativity really lit up the room as they explored the difference between these two circuit types by powering LED lights in each of these styles.
Ask your student: What is the main difference between parallel and series circuits? (Only one path in a series circuit; parallel there are multiple paths) Which circuit style causes voltage drop? (series)
Fun Fact: Refrigerators, freezers, and water heaters use series circuits while electrical outlets in a room, house, or building use parallel circuits.
Springfield STEMvironment 8/2: 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)
Springfield MicroSTEM 8-2: 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)
