Addressing STEM Concepts through a Food Safety Activity

ABSTRACT The activity described in this article engages students in learning about proper meat storage procedures by using the Internet. They apply their knowledge practically through creation of a pamphlet to be displayed in their kitchen at home and a follow-up report on their parents’ kitchen procedures; they may also participate in a classic food storage experiment. This activity is well suited for elementary school children in the second through fourth grades and promotes all basic STEM (science, technology, engineering, and math) concepts. Kitchen activities require all these concepts for successful and safe outcomes. The examination of food storage devices references engineering, and technology is used for the research and pamphlet creation. The section on bacteria introduces life sciences, and physical sciences come into play through the discussion of heat inducing change in the meats. Math skills are integral to the reference table containing temperatures and times.

Scientific Inquiry into Home Electronic Technology Usage.

ABSTRACT This activity promotes ways to save electricity in the home. Students identify electronic devices in the home and examine wattage, hours of use per month, estimated wattage per month, kilowatt hours per month, average retail price per kilowatt hour in each state, and the estimated cost per month. Students gain an appreciation for how saving power saves money and betters the environment. This interdisciplinary activity promotes science, technology, mathematics, and English language arts.

Using an Activity to Simulate the Dangers of Multitasking with Technology while Walking.

ABSTRACT People are increasingly trying to multitask while walking. Text messaging while walking is a significant area for concern. The number of text messages sent is expected to be more than 8 trillion in 2012. Texting is becoming so commonplace that people use this technology while engaged in other activities. The dangers of multitasking have hit the streets as people are becoming involved in more accidents while walking as they text on mobile phones. This simulation activity measures a students ability to multitask by texting and walking. The activity simulates walking in the real world and is best suited for middle school students. Additional activities, after completing the simulation, will challenge middle school students to learn more about multitasking globally through scientific inquiry researched on the Internet. The students will use language arts skills to generate a report or presentation to share with classmates. Their findings will give the entire class a cultural perspective on accident statistical comparisons between different countries.
