Shadow Stick: Design A Sun Measuring Device for a Window

I still need to print this design in 3D before I share pictures of it online later this fall. Younger elementary students are tasked with exploring science concepts, specifically (NGSS 1-ESS1), which focuses on the Earth's place in the universe. One key idea, ESS1.A, is that patterns in the sun, moon, and stars can be observed, described, and predicted over time. Students must use Science and Engineering Practices, such as planning investigations, to create devices using 3D design software that allow them to observe classroom windows for shadows or sunlight. These simple devices should be able to track hourly, daily, and seasonal changes in the sun's position. By doing this, students can record their observations over time and see patterns emerge. This concept is extended when students use technology and math skills to create a STEM unit that incorporates design thinking and problem-solving. Both NGSS standards 1-ESS1-1 and 1-ESS1-2 can be supported by using 3D technology software to design devices that capture sunlight and shadows over time, allowing students to measure changes in the sun's position throughout the day and across different seasons.
