Use of these programs provides valuable assistance in determining the accuracy and precision of real-world measurements collected in the field. To do this, engineers collect data and rely on technology such as spreadsheets-like Microsoft® Excel® and Google Sheets-to help them analyze the data. In every engineering field, researchers are continually innovating and improving existing devices. This engineering curriculum aligns to Next Generation Science Standards ( NGSS). Students present their findings and conclusions, including making recommendations for temperature sensor improvements. By averaging the standard deviations of each minute’s temperature reading, students determine the accuracy of their temperature sensors. Then, the class combines all the team data points in order to compare data collected from numerous devices and analyze the accuracy of their recording devices by finding the standard deviation of temperature readings at each minute. Groups analyze their collected data by finding the mean, median, mode, and standard deviation. Teams record soil temperature data during a class period while making changes to the samples to mimic real-world crop conditions-such as the addition of water and heat and the removal of the heat. Working as if they are engineers aiming to analyze and then improve data collection devices for precision agriculture, students determine how accurate temperature sensors are by comparing them to each other. ![]()
