Springfield Engineering Explorations 8-3: Racing Against the Sun

Springfield Engineering Explorations 8-3: Racing Against the Sun

Today, our engineers explored how their knowledge could be applied to the real world, by building solar cars! In this first part of a two part lesson, the students tested how different types of light effected their motors. Then, they got the wheel rolling by creating the body of their solar cars. Tomorrow they’ll complete their cars and put them to the test!

Ask your student: What is a solar cell? (It’s the “battery” of the car; it converts light into energy)

Fun fact:  The first solar cars were built in the 1950’s.

Springfield STEMvironment 8/3: Pond Water!

Springfield STEMvironment 8/3: Pond Water!

Today, in STEMvironment, the students analyzed samples of water from a local pond to look for insect nymphs which can be seen with the naked eye. Students learned the importance of a healthy ecosystem and that in aquatic ecosystems, the more diverse the organisms in a body of water, the more vibrant and healthy it is. Using this knowledge, students could analyze the health of the ecosystem from which the water sample was gathered.

Ask your student: What is a macroinvertebrate? (A small animal without a backbone that can be seen without a stereoscope or microscope)

Springfield MicroSTEM 8-3: Magnifying Microscopes

Springfield MicroSTEM 8-3: Magnifying Microscopes

Today, the investigation of different kinds of magnifying devices continued. Students got the chance to go outside and collect various samples of their choice. After collection, the samples were brought inside to be analyzed with a compound light microscope. Students also reviewed the various parts of a compound microscope, and the importance of each part in the function of the microscope as a whole.

Ask your student: What similarities and differences did you notice when you were using the different tools for magnification (MicroPhone lens, hand lens, compound light microscope, and stereoscope)?
