Throughout this academic year, seventh-grade science students have literally and figuratively probed the intricate world of body systems. Their most recent unit on cells and cellular activity had students engaged in researching organelles, the small but mighty structures within our body, and understanding the mysteries of cellular respiration.
Organelles or “little organs” play a special role in the cellular world, like the heart, liver, stomach, and kidneys, which function within a human or animal. These microscopic structures are a significant part of maintaining a cell’s vitality.
The nucleus, one of the most famous organelles, is the cell’s command center, housing essential DNA. Another key player is the mitochondria, which produce ATP, a vital energy source for organisms. Lysosomes are responsible for the digestion and recycling of toxins and waste, with their production orchestrated by the Golgi complex. This larger organelle also supports the various functions of the cell.
Once familiar with the parts and functions of a cell, students created 3D interactive models based on a chosen type of body cell, such as the pancreas or liver. Using the power of technology, they employed Scratch—a coding platform using blocks of code—and Makey Makey—an innovative electrical wiring tool that interacts with Scratch.
Makey Makey is a USB device that transforms everyday objects into computer interfaces. Students can turn ordinary objects into keys on the keyboard, thus creating the name Makey Makey (Make + Key).
With the help of Middle School Science Teachers Nolan Clarke, Michelle Bouchard, and Branson Lawrence, students combined materials from the classroom and Middle School Makerspace to build and operate their specialized cells. This hands-on project provided opportunities for cooperation within groups, combining knowledge of cells, electricity, and coding, as well as using power tools and the ever-important glue gun.
Students gained practical insights and knowledge through this exploration of cells and the blend of creativity and technology. The fascinating world of organelles provides endless opportunities for exploration!
