Chapter Overview
Chapter 11 Technology in Everyday Life connects scientific concepts with practical engineering, agriculture, food science, and medical applications. Students examine water conservation strategies, identifying key factors causing water scarcity and building working models of drip and sprinkler irrigation systems to maximize agricultural water efficiency.
The chapter explores food preservation technologies designed to prevent microbial spoilage and extend shelf life. It details six essential preservation methods: Canning (heat sterilization in airtight containers), Freezing (low temperature micro-growth inhibition), Drying/Dehydration (moisture removal), Pickling (acidic pH preservation), Dry Salting (osmotic moisture extraction), and Curing (salt and nitrate treatment).
Additionally, the chapter investigates healthcare devices, explaining how a Stethoscope amplifies acoustic heart and lung sounds through a chest piece, diaphragm, and binaural tubing, as well as the germicidal mechanism of alcohol-based Hand Sanitizers in destroying pathogens. Mastering these applied technologies prepares FBISE students for conceptual SLO board exam questions.
